This incoming call response is a signal that responds to the outgoing call request, and is a signal that complies with a communication method that the communication device 6 complies with. When the incoming call response reaches the communication device 5, a call connection is established between the communication device 5 and the communication device 6, and a call state is established, and a security guard possessing the communication device 5 and a security staff possessing the communication device 6 Calls can be made between them.

  When the communication device 5 receives the incoming response from the communication device 6, the communication device 5 and the communication device are based on the priority and the communication possible time for the communication device 5 and the priority and the communication available time for the communication device 6. A communication permission time determining process for determining a communication permission time during which communication between the six terminals is permitted is performed (step S103). Details of the communication permission time determination process will be described later. The communication device 5 measures the time from the start of communication with the communication device 6 until the communication permission time determined in the communication permission time determination process elapses (step S104). A disconnection request is transmitted (step S105). This disconnection request is a signal for disconnecting the call connection with the communication device 6 and ending the call, and is a signal in accordance with a communication method that the communication device 5 complies with.

  The communication device 6 that has received the disconnection request returns a disconnection response to the communication device 5 (step S106). This disconnection response is a signal that responds to the disconnection request, and is a signal that complies with a communication method that the communication device 6 complies with. Thereafter, the communication connection between the communication device 5 and the communication device 6 is disconnected.

  Next, details of the center device 4 to which the present invention is applied will be described. FIG. 3 shows a functional block diagram of the center device 4. As illustrated in FIG. 3, the center device 4 includes a communication processing unit 41, an IP communication processing unit 42, a storage unit 43, a display unit 44, an operation unit 45, and a control unit 46.

Is included.

The user table and time table will be described in detail.
The user table is information in which the identification information of the communication devices 5 and 6 is associated with the priority regarding the user who owns the communication device, and the user or the user who owns each communication device 5 or 6 It is updated when the current state of the person is changed. For the identification information of the communication devices 5 and 6, the telephone numbers of the communication devices 5 and 6 are used.
The priority includes the department belonging to the user who is in charge of the user who uses the communication devices 5 and 6, the user's job title (position), the user's own duties, the contents of work performed by the user, etc. It is determined according to the current status indicating the current business status of the user. For example, when departments are used as priorities, control departments that manage guards at facilities where the center device 4 is installed, business departments to which guards belong, sales departments that handle customers such as sales, general affairs, accounting, etc. The management department is set as the control department, the business department, the sales department, and the management department in descending order of priority.
Note that the high priority does not always correspond to the length of the callable time.

Next, the time table will be described in detail.
The callable time is preset for each priority. For example, the control department is not limited because it is necessary to make a high-priority communication with the related places. The business department is assumed to be outside the company where there is a risk of information leakage due to countermeasures, etc., and it is necessary to receive an emergency response instruction from the control department without delay. . The sales department is 30 minutes and the management department is 20 minutes. As described above, a department with a high priority is not necessarily allowed to talk for a long time, but sets a callable time required for a user who works for the job.
The priority is information according to the duties of the user who uses the communication devices 5 and 6, and represents the degree to which the callable time set for the duties should be emphasized in relation to other duties. Yes.
Here, job information in the present invention is information that is input to the center device to determine priority, and is at least of the user's department, position, and current job status. Any one shall be included.
In this way, the storage unit 43 stores a time table representing the relationship between the department to which the priority belongs and the callable time set for each.

When the user's current state is used in addition to the department to which the user belongs as a priority, the current state is set as a detailed category of the department to which the priority is assigned in the user's current state. For example, the current status (current business status) of the users in the business department, that is, the current status of work (current business status), “on-going” is the status where the site is being checked at the property where the anomaly has occurred. Immediately after the response has been completed, regular inspection of the target property in the building or around the building is in progress, and there is no instruction or plan for the response to the security headquarters or standby “Waiting”, which is a state of waiting at a place, is set as “handling”, “patrolling”, “waiting”, and “handling completed” in descending order of priority.
The callable time corresponding to each current state is set to be shorter as the urgency of the work is higher. For example, during handling, it should be set to 1 minute since calls that are more than necessary should be restricted, 3 minutes during patrol, 15 minutes during standby, and 30 minutes after the handling of reporting the handling result.
The current status may be used in the same way for other departments. For example, in the sales department, as the current state of the salesperson who is a user, “serving customers”, which is in the state of serving customers, is 5 minutes, and “moving” is the state where he is heading to the next destination. “In office”, which is a state where office work is performed at the office for 10 minutes, is set to 30 minutes, and priority is set in the order of customer service, movement, and office.

  Further, when the user's position is used as the priority, the higher the position is, the higher the priority is, and the callable time is set to be long. For example, the manager is 30 minutes, the leader is 20 minutes, the senior staff is 15 minutes, and the staff is 10 minutes. In addition, the department and position are used in combination, and the position is set as a detailed classification within the department. The higher the position within the department, the longer the available call time and the higher the priority.

  The display unit 44 is configured by a display device such as a liquid crystal display or a touch panel display, and functions as a notification unit for notifying the monitor of the property where the security device 2 that has transmitted the abnormality detection signal is installed, the content of the detected abnormality, and the like. To do. Further, the display unit 44 displays an input screen or the like when the monitor inputs priority information regarding the user who uses the communication devices 5 and 6 to the center device 4, that is, information such as department, job title, and current status. .

  The operation unit 45 is configured by operation devices such as a keyboard and a mouse, and an input for the monitor to input information such as a department to which the user who uses the communication devices 5 and 6 to the center device 4, a position, and a current state is input. Functions as a device. In addition, when the display part 44 is comprised with the touchscreen display, the operation device mentioned above can also be abbreviate | omitted.

The control unit 46 includes one or a plurality of processors and their peripheral circuits. And the control part 46 determines communication permission time according to the priority regarding the user who has the communication apparatuses 5 and 6, and notifies the determined call permission time to the communication apparatus 5. FIG. For this purpose, the control unit 46 includes a setting unit 461 and a determination unit 462 as functional modules implemented by software operating on the processor.
Note that these units included in the control unit 46 may be configured by independent integrated circuits, firmware, a microprocessor, and the like.
Hereinafter, each part of the control part 46 is demonstrated in detail.

The setting means 461 changes the priority set for the communication devices 5 and 6 every time the user who owns the communication devices 5 and 6 changes, and whenever the current state of the user changes, and sets the user table. Update. When the information such as department, job title, and current state is input to the user who owns the communication devices 5 and 6 via the operation unit 45, the setting unit 461 corresponds to the identification information of the communication devices 5 and 6. To set the priority for the user and update the user table. Moreover, if each information regarding a user is acquired from the communication apparatuses 5 and 6, a user table will be updated. The center device 4 may be configured to store the user ID code, the department to which the user belongs, and the position in advance in association with each other, and obtain the authenticated user ID code from the communication devices 5 and 6. .
Since the priority table shows the relationship between the priority and the communicable time, when the information regarding the user of the communication devices 5 and 6 changes and the user table is updated, the communication device 5 and 6 is handled. The communication time is also automatically changed.

  When the setting unit 461 updates the user table, the determination unit 462 refers to the time table and extracts the communicable time for the updated communication devices 5 and 6. Then, the identification information of the communication devices 5 and 6 to be updated, the priority related to the user, and the communication possible time are associated with each other, and the communication devices 5 and 6 in the system are notified via the communication processing unit 41.

  Next, details of the communication devices 5 and 6 to which the present invention is applied will be described. In addition, since the structure of the communication apparatus 5 and the communication apparatus 6 is the same, below, the communication apparatus 5 is demonstrated as a representative. FIG. 4 shows a functional block diagram of the communication device 5. As illustrated in FIG. 4, the communication device 5 includes a communication processing unit 51, a display unit 52, an operation unit 53, a storage unit 54, and a control unit 55.

  The communication processing unit 51 includes an interface circuit for performing wireless communication between the base station device 7 and a mobile phone in accordance with a communication method such as W-CDMA, CDMA2000, or LTE through an antenna. Then, under the control of the control unit 55, the communication processing unit 51 transmits a call origination request, an incoming call response, a disconnection request, and a disconnection response to the partner communication device via the base station device 7 and the mobile phone network 10, and the mobile phone network 10 The call origination request, the incoming call response, the disconnection request, and the disconnection response received from the partner communication device via the base station device 7 are transmitted to the control unit 55. In addition, the communication processing unit 51 controls the identification information of each communication device received from the center device 4 via the mobile phone network 10 and the base station device 7, the priority associated with the identification information, and the communicable time information. To 55.

  The display unit 52 includes a display device such as a liquid crystal display or a touch panel display, and displays a screen for outgoing or incoming call processing, various information received from the control unit 55, and notifies the security guard.

The operation unit 53 is an operation interface for a guard to operate the communication device 5. The operation unit 53 is composed of an input device such as a numeric keypad, accepts various operations from security guards, and outputs signals corresponding to those operations to the control unit 55. A user who owns the communication device 5 first inputs an ID code as an operation for registering that the owner is himself / herself in the communication device 5. In the case of a configuration in which the relationship between each user's ID code and the priority of the department to which the user belongs is registered in the center device 4, the department and position are entered in addition to the ID code. When registering a user, it is desirable to improve reliability by authentication using a password or biometric authentication using a fingerprint or the like. In addition, the contents of work at work are input at any time and registered as the current state of the user. For example, when the user in the business department finishes patrol in the property, the operation unit 53 is operated to change the current state to standby. Each information regarding the user input here is registered in the communication device 5 and is transmitted to the center device 4 by the processing of the control unit 55.
When the display unit 52 is configured with a touch panel display, the function of the operation unit 53 may be realized by displaying a keyboard screen for a guard to input various operations on the touch panel display. In that case, the operation unit 53 outputs signals corresponding to these operations to the control unit 55 when the user operates the keyboard screen.

  The storage unit 54 includes a semiconductor memory such as a ROM (Read Only Memory) and a RAM (Random Access Memory). The storage unit 54 stores a computer program, various parameters, and various data for controlling the communication device 5, and inputs / outputs such information to / from the control unit 55. The various data includes the identification information of each communication device in the security system 1 input through the operation unit 53 or received from the center device 4, and the priority and communicable time information associated with the identification information. included. Further, a time table stored in the center device 4 may be stored.

The control unit 55 includes one or a plurality of processors and their peripheral circuits. And the control part 55 determines communication permission time based on the priority and communication possible time about the other party communication apparatus 6 which performs voice communication with the communication apparatus 5, and starts the telephone call with the other party communication apparatus 6. When the determined communication permission time elapses, the call is terminated. For this purpose, the control unit 55 includes a setting unit 551 and a determination unit 552.
Note that these units included in the control unit 55 may be configured by independent integrated circuits, firmware, a microprocessor, and the like.
Hereinafter, each part of the control part 55 is demonstrated in detail.

  When the setting unit 551 receives the identification information of each communication device in the security system 1 from the center device 4 via the communication processing unit 51, the priority associated with the identification information, and the communicable time, the received communication device Are stored in the storage unit 54 in association with each other. In addition, when information about the user who possesses the communication device 5 such as the priority and the current state is input via the operation unit 53, the identification of the own communication device 5 stored in the storage unit 54 by these information is performed. The priority associated with the information and the communicable time are updated, and the update content is transmitted to the center device 4 via the communication processing unit 51.

The determination unit 552 acquires the telephone number of the partner communication device 6 input via the operation unit 53 as identification information of the partner communication device 6 when a caller performs a call operation. Further, the determination unit 552 reads the priority associated with the identification information of the communication device 5 and the priority associated with the identification information of the counterpart communication device 6 from the storage unit 54 and compares the priorities of the two. The determination unit 552 reads the communication available time associated with the identification information of the higher priority device from the storage unit 54, and determines the read communication available time as the communication permission time in the call with the counterpart communication device 6. . For example, even if the user belonging to the communication device 5 on the calling side belongs to the management department and can make a 20-minute call, the user department belonging to the communication device 6 on the receiving side is dealing with the business department. Since the priority of the business department is higher than that of the management department, the communication-enabled time of 1 minute set for the user being dealt with in the business department is determined as the communication permission time, and a call can be made between both parties for only 1 minute.
In addition, the determination unit 552 counts the time from the start of a call with the partner communication device 6, and when the determined communication permission time has elapsed, causes the communication processing unit 51 to transmit a disconnection request to the partner communication device 6. The communication with the partner communication device 6 is disconnected.

  FIG. 5 is a flowchart showing the operation of the communication permission time determination process executed by the control unit 55 according to the first embodiment. The communication permission time determination process shown in FIG. 5 is executed in step S103 of FIG.

  First, the determination unit 552 reads the priority associated with the identification information of the communication device 5 that is the device itself from the storage unit 54 (step S201). Further, the determination unit 552 reads the priority associated with the telephone number that is the identification information of the partner communication device 6 input via the operation unit 53 from the storage unit 54 (step S202). Next, the determination unit 552 determines whether the priority for the communication device 5 is equal to or higher than the priority for the partner communication device 6 (step S203). And when the priority about the communication apparatus 5 is more than the priority about the other party communication apparatus 6, the communication possible time linked | related with the identification information of the communication apparatus 5 is read from the memory | storage part 54, and the read communication possible time is the said It is determined as a communication permission time in a call (step S204). On the other hand, when the priority for the communication device 5 is lower than the priority for the other communication device 6, the communication available time associated with the identification information of the other communication device is read from the storage unit 54, and the read communication available time is used as the call communication time. Is determined as the communication permission time at (step S205).

As described above, in the communication system according to the first embodiment, priorities and communication possible times for the communication device and the partner communication device are set in advance in the communication device, and the communication with the partner communication device is performed. When the communicable time for the higher priority device of the own device and the partner communication device has elapsed, the communication with the partner communication device is disconnected. In this way, for voice communication between communication devices, communication permission time is determined by comparing priorities determined by both users' departments and the current status, so careless work is not required. It is possible to suppress long-time calls.
For example, when a security guard in a business department talks to an employee in a sales department, the talk time is limited to the communicable time assigned to the security guard, so a call can be made while the guard is handling on-site. The time is limited to a short time, and an emergency call from a supervisor or the like becomes possible. On the other hand, after the countermeasure is completed and safety is confirmed, a long-time call is possible. In addition, when a security guard in the business department makes a call with a supervisor or supervisor of the control department, the call can be made only for the communicable time allocated to the supervisor or supervisor. Can report and receive instructions.

  The present invention is not limited to the above-described embodiment, and many changes and modifications can be made. For example, the communication device may be a PHS instead of a mobile phone. Moreover, although this embodiment demonstrated the security system as an example, the communication system which concerns on this invention is applicable also to the system used by the police, the Self-Defense Force, the local government, etc.

  When the priority for the communication device 5 is the same as the priority for the partner communication device 6, the communicable time for the partner communication device 6 is not used as the communication permission time, but the communicable time for the partner communication device 6 is used. It is good also as communication permission time. Alternatively, when the priority for the communication device 5 is the same as the priority for the partner communication device 6, the longer of the communicable time for the communication device 5 and the communicable time for the partner communication device is set as the communication permission time. Also good. Alternatively, if the restriction on the call time is strongly operated, the shorter of the communicable time for the communication device 5 and the communicable time for the partner communication device 6 may be used as the communication permission time.

  Alternatively, the communication permission time determination process and the communication disconnection process may be performed by the incoming communication device 6 instead of the outgoing communication device 5. In this case, the determination unit 552 of the incoming communication device 6 acquires the identification information of the communication device 5 included in the outgoing call request received from the outgoing communication device 5 via the communication processing unit 51, and identifies the own device. The priority associated with the information and the priority associated with the identification information of the communication device 5 are compared, and the communication allowable time for the device with the higher priority is set as the communication permission time, and communication with the communication device 5 is started. When the communication permission time elapses, the communication processing unit 51 is disconnected from the communication device 5.

  Further, the communication device 5 receives the priority and communication available time information about the counterpart communication device 6 from the counterpart communication device 6 via the communication processing unit 51 instead of acquiring the priority and the communicable time information by reading from the storage unit 54. May be obtained by In this case, the control unit 55 of the communication device 6 on the incoming side includes the priority and communication available time information about the own device in the incoming response and transmits the information to the communication device on the transmission side. The determination unit 552 of the communication device 5 on the transmission side can communicate with the device having the higher priority by comparing the priority for the own device with the priority for the other communication device 6 received from the other communication device 6. The time is determined as the communication permission time. In this case, the storage unit 54 does not need to store the priority and communicable time information for communication devices other than its own device, and can simplify the management of the priority and communicable time information. Further, when the communication device 5 stores the time table stored in the center device 4, priority can be acquired from the partner communication device 6, and communication with the partner communication device 6 can be performed with reference to the time table. Time may be specified.

  Further, when the identification information of the communication devices 5 and 6 is information other than the telephone number, the control unit 55 includes the identification information of the own device in the incoming call response when the incoming call is received, and transmits the call via the communication processing unit 51. To the communication device 5 on the side. The determination unit 552 of the communication device 5 on the transmission side acquires identification information of the partner communication device from the incoming response received from the partner communication device 6 via the communication processing unit 51.

  Further, the communication devices 5 and 6 may display the communication permission time determined in the communication permission time determination process on the display unit 52 to notify the user of the communication permission time. Further, the determination unit 552 transmits information indicating the determined communication permission time to the partner communication device via the communication processing unit 51, and the determination unit 552 on the partner communication device side also causes the display unit 52 to display the communication permission time. The communication permission time may be notified to the user. Furthermore, the remaining time of the communication permission time may be displayed in a countdown manner according to the elapsed time from the communication connection. Note that the information indicating the communication permission time is transmitted as a message in accordance with a communication method that the communication device 5 complies with.

Moreover, you may set a priority as a priority regarding a user according to the place where the user of the communication apparatuses 5 and 6 is present. For example, when setting the priority based on the current position instead of the priority based on the current status for the user belonging to the business department, the location of the property to be dealt with and the surrounding area designated by the monitor are set to the first specific position. The location of the property to be visited and its surrounding area is the second specified position, the location of the establishment used when standing by and the surrounding area is the third specified position, and other places such as crowds Treat as non-specific position. And the first specific position, the second specific position, where there is a high business urgency and the need to minimize the call time, the non-specific position where there is a risk of leakage of call contents to a third party, and the business urgency The priority is set higher in the order of the lower third specific position. The possible call time is, for example, 1 minute at the first specific position, 2 minutes at the second specific position, 15 minutes at the third specific position, and 3 minutes at the non-specific position.
When using the current position of the user as a priority, the communication devices 5 and 6 are provided with a positioning function using GPS satellite or mobile phone base station communication, and the device is included in any specific position, or not It is determined whether it is included in a specific position, and the priority of the own device is set. Then, when a call is made from the communication device 5 to the communication device 6, information indicating the priority or the current position of the communication device 6 is added to an incoming call response from the communication device 6, so that the communication devices 5, 6 The communication device 5 determines which priority is higher, and determines the communication permission time. In this way, for voice communication between communication devices, the communication permission time is determined by comparing the priority determined by the department to which both users belong and the current location. It is possible to suppress long-time calls.

Further, the present invention can be applied not only to hardware but also to a program that causes hardware to perform predetermined processing.
For example, a multi-function mobile phone, a so-called smartphone or the like can be used as the communication device 5 and can be implemented as one of applications that are downloaded and installed from the mobile phone network 10 to a smartphone as appropriate.
In this case, general functions as a communication device such as the communication processing unit 51, the display unit 52, the operation unit 53, the storage unit 54, the hardware resources of the control unit 55, and the call processing in the control unit 55 in the above-described embodiment. The software resource that realizes is installed in the smartphone in advance. Therefore, the program to which the present invention is applied is a program that realizes the functions of the setting unit 551 and the determination unit 552 in the control unit 55, and this program controls the above-described hardware resources and software resources included in the smartphone in advance. You just have to do it.

  Next, a security system according to the second embodiment of the present invention will be described. The overall system configuration of the security system according to the second embodiment is the same as that of the security system 1 according to the first embodiment shown in FIG. However, in the security system according to the second embodiment, when the priority of the communication device on the transmission side is higher than the priority of the communication device on the reception side, communication is permitted for the longer of the communicable time for each communication device. When the priority of the communication device on the caller side is lower than the priority of the communication device on the callee side, the shorter of the communicable times for each communication device is set as the communication permission time. The telephone call is started by the intention of the person on the outgoing side, and is performed in order for the outgoing person to communicate the message to the other party or to hear something from the other party. For this reason, if the caller's priority is higher than that of the callee, for example, the longer communicable time should be set so that a sufficient amount of call time is available to give detailed instructions to subordinates or listen to reports from subordinates. Use. On the other hand, if the priority on the called side is higher than that on the calling side, in order to avoid hindering the work of the user on the called side, for example, to limit to the minimum call time necessary to report to the supervisor, Use the shorter available call time.

  The operation sequence diagram of the communication connection process of the communication device 5 and the communication device 6 in the security system 1 according to the second embodiment is the same as the operation sequence diagram shown in FIG.

  Next, details of the communication device 5 according to the second embodiment will be described. In addition, since the structure of the communication apparatus 5 and the communication apparatus 6 is the same, below, the communication apparatus 5 is demonstrated as a representative. The main configuration of the communication device 5 according to the second embodiment is the same as that of the communication device 5 according to the first embodiment shown in FIG. 4, but the function of the control unit 55 is partially different.

  In the second embodiment, the determination unit 552 determines whether the priority for the communication device 5 on the transmission side is equal to or higher than the priority for the communication device 6 on the reception side. When the priority for the communication device on the transmission side is equal to or higher than the priority for the communication device on the reception side, the determination unit 552 determines the communication possible time for the communication device 5 on the transmission side and the communication on the communication device 6 on the reception side. Of the possible times, the longer time is determined as the communication permission time. On the other hand, when the priority for the communication device 5 on the transmission side is lower than the priority for the communication device 6 on the reception side, the determination unit 552 determines the communicable time for the communication device 5 on the transmission side and the communication device 6 on the reception side. The shorter one of the communicable times is determined as the communication permission time.

  FIG. 6 is a flowchart showing the operation of the communication permission time determination process executed by the control unit 55 according to the second embodiment. The communication permission time determination process shown in FIG. 6 is executed in step S103 of FIG.

  First, the determination unit 552 reads the priority level and communicable time information associated with the identification information of the communication device 5 on the transmission side from the storage unit 54 (step S401). Further, the determination unit 552 reads the priority level and the communicable time information associated with the identification information of the called party communication device 6 from the storage unit 54 (step S402). Next, the determination unit 552 determines whether or not the priority for the communication device 5 on the transmission side is equal to or higher than the priority for the communication device 6 on the reception side (step S403). When the priority for the communication device 5 on the transmission side is equal to or higher than the priority for the communication device 6 on the reception side, the communication possible time for the communication device 5 on the transmission side and the communication device 6 on the reception side The longer time of the communicable time is determined as the communication permission time (step S404). On the other hand, when the priority for the communication device 5 on the transmission side is lower than the priority for the communication device 6 on the reception side, the communication possible time on the communication device 5 on the transmission side and the communication on the communication device 6 on the reception side. The shorter of the possible times is determined as the communication permission time (step S405).

As described above, in the communication system according to the second embodiment, when the priority of the communication device on the outgoing side is higher than the priority of the communication device on the incoming side, the longer communication possible time for each communication device Is the communication permission time, and when the priority of the calling communication device is lower than the priority of the receiving communication device, the shorter of the communicable times for each communication device is set as the communication permission time. As a result, as in the first embodiment, it is possible to suppress inadvertent long-time use within a range that does not hinder business operations.
For example, when a supervisor sends a message to a subordinate communication device with a low priority from a communication device with a high priority to confirm the situation with the subordinate, the longer communication possible time assigned to each communication device Time is allowed and the situation can be checked over time. Conversely, when a subordinate sends a call from a lower-priority subordinate communication device to a higher-priority communication device in order to report the situation to the superior, the communication time is communicated to each communication so that the situation is simply reported. It is possible to limit to the shorter communicable time of the communicable time allocated to the device.

If the priority for the communication device 5 on the sending side is the same as the priority for the communication device 6 on the receiving side, the shorter of the communicable time for the communication device 5 and the communicable time for the counterpart communication device 6 This time may be the communication permission time.
Moreover, also in the security system of 2nd Embodiment, the change and deformation | transformation similar to 1st Embodiment are possible.

  Next, a security system according to a third embodiment of the present invention will be described. The overall system configuration of the security system according to the third embodiment is the same as that of the security system 1 shown in FIG. However, in the security system 1 according to the third embodiment, the center device 4 determines the communication permission time based on the priority of the communication devices 5 and 6, and the communication device 5 determines the communication permission time determined by the center device 4. When elapses, communication with the partner communication device 6 is disconnected.

  FIG. 7 is an operation sequence diagram of communication connection processing of the communication device 5, the communication device 6, and the center device 4 in the security system 1 according to the third embodiment. In this operation sequence diagram, an example in which a security officer who performs confirmation or countermeasure of the security device 2 transmits a call from the communication device 5 to the communication device 6 possessed by another security officer in order to convey an emergency requirement will be described. To do.

First, when making a call to the communication device 6, the communication device 5 sends a call request to the communication device 6 (step S501).
On the other hand, when receiving a call request from the communication device 5, the communication device 6 returns an incoming call response to the communication device 5 (step S502). When the incoming call response reaches the communication device 5, a call connection is established between the communication device 5 and the communication device 6, and a call state is established. Between the user who owns the communication device 5 and the user who owns the communication device 6. You can make a call.

Upon receiving the incoming response from the communication device 6, the communication device 5 transmits to the center device 4 identification information of the communication device 5, identification information of the communication device 6, and an acquisition request for the communication permission time (step S503). .
When the center device 4 receives the communication permission time acquisition request from the communication device 5, the center device 4 refers to the user table and the time table, the priority and the communicable time associated with the identification information of the communication device 5, and the communication device 6. A communication permission time determination process for determining a communication permission time is performed based on the priority and the communication possible time associated with the identification information (step S504). Details of the communication permission time determination process will be described later. Next, the center device 4 transmits communication permission time information indicating the communication permission time determined in the communication permission time determination process to the communication device 5 (step S505).

Upon receiving the communication permission time information from the center device 4, the communication device 5 measures the time until the communication permission time elapses after starting communication with the communication device 6 (step S506). A disconnection request is transmitted to the communication device 6 (step S507).
The communication device 6 that has received the disconnection request returns a disconnection response to the communication device 5 (step S508). Thereafter, the communication connection between the communication device 5 and the communication device 6 is disconnected.

  Next, details of the communication device 5 according to the third embodiment will be described. In addition, since the structure of the communication apparatus 5 and the communication apparatus 6 is the same, below, the communication apparatus 5 is demonstrated as a representative. In the communication device 5 according to the third embodiment, the functions of the storage unit 54 and the control unit 55 are partially different among the units of the communication device 5 according to the first embodiment shown in FIG.

In the third embodiment, since communication center time 4 is determined based on priority, the center device 4 does not store information on priority and communication time for each of the communication devices 5 and 6. May be.
The setting unit 551 transmits the update content to the center device 4 via the communication processing unit 51 when information regarding the user who possesses the communication device 5 such as the priority and the current state is input via the operation unit 53. .
Instead of performing the communication permission time determination process, the determination unit 552 sends the communication processing unit 51 the identification information of the communication device 5 that is its own device, the identification information of the partner communication device 6, and the request for acquisition of the communication permission time. To the center device 4 through the communication device, and the communication permission time is acquired from the center device 4. And the time after starting communication with the other party communication apparatus 6 is timed, and when the communication permission time notified from the center apparatus 4 elapses, a disconnection request is transmitted to the other party communication apparatus 6 via the communication processing unit 51. And end the call.

Next, details of the center device 4 according to the third embodiment will be described. In the center device 4 according to the third embodiment, the functions of the control unit 46 are partially different among the respective units of the center device 4 according to the first embodiment shown in FIG.
The determination unit 462 determines a communication permission time for voice communication between the communication device 5 and the communication device 6. When receiving the communication permission time acquisition request from the communication device 5, the determination unit 462 refers to the user table stored in the storage unit 43 and uses the identification information of the communication device 5 and the communication device 6 received together with the acquisition request. The associated priority is read, and both priorities are compared. The determination unit 462 refers to the time table in the storage unit 43, reads out the communicable time set for the higher priority among the priorities of the communication device 5 and the communication device 6, and uses this time as the communication permission time. decide.
The determination unit transmits the determined communication permission time via the communication processing unit 41 to the communication device 5 that has transmitted the communication permission time acquisition request.

  FIG. 8 is a flowchart showing the operation of the communication permission time determination process executed by the control unit 46. The communication permission time determination process shown in FIG. 8 is executed in step S504 in FIG.

  When receiving the communication permission time acquisition request from the communication device 5, the determination unit 462 refers to the user table in the storage unit 43 and uses the identification information of the communication device 5 received from the communication device 5 via the communication processing unit 41. The associated priority is read (step S601). Similarly, the priority associated with the identification information of the communication device 6 received from the communication device 5 is read (step S602). Next, the determination unit 462 determines whether or not the priority for the communication device 5 is equal to or higher than the priority for the communication device 6 (step S603). If the priority for the communication device 5 is equal to or higher than the priority for the communication device 6, the communication unit 5 reads the communication available time associated with the identification information of the communication device 5 by referring to the time table in the storage unit 43. The communication available time is determined as the communication permission time for the call for which the acquisition request is made (step S604). On the other hand, when the priority for the communication device 5 is lower than the priority for the communication device 6, the communication available time associated with the identification information of the communication device 6 is read, and the read communication available time is determined as the communication permission time ( Step S605).

  As described above, in the communication system according to the third embodiment, the center apparatus determines the communication permission time based on the priority of each communication apparatus that performs a call, and the communication apparatus determines the communication determined by the center apparatus. When the permission time elapses, the communication with the partner communication device is disconnected. As a result, as in the first embodiment, it is possible to suppress inadvertent long-time calls within a range that does not hinder business.

In the security system of the third embodiment, the same changes and modifications as in the first embodiment are possible.
The configuration of the second embodiment can also be applied to the third embodiment. In this case, when the center device 4 receives the acquisition request for the communication permission time from the communication device 5, the center device 4 recognizes the communication device 5 that is the transmission source of the acquisition request as a transmission-side device, and receives the other communication device 6 as an incoming call. Recognize as a side device. And, when the priority for the communication device on the caller side is equal to or higher than the priority for the communication device on the callee side, among the communicable time for the communication device on the caller side and the communicable time on the communication device on the callee side, If the longer time is determined as the communication permission time and the priority for the communication device on the caller side is lower than the priority on the communication device on the callee side, the communication possible time for the communication device on the caller side and the communication on the callee side Of the communicable times for the apparatus, the shorter time is determined as the communication permission time. The center device 4 includes the transmission device information indicating which of the communication devices 5 and 6 is the transmission-side device in the acquisition request, instead of using the transmission-side communication device as the transmission-side device. The center device 4 may be configured to discriminate between the transmitting device and the receiving device based on the transmitting device information.

  Next, a security system according to a fourth embodiment of the present invention will be described. The overall system configuration of the security system according to the fourth embodiment is a configuration in which the center device 4 determines the call permission time between the communication device 5 and the communication device 6 as in the security system 1 according to the third embodiment. . However, in the security system 1 according to the fourth embodiment, the communication device 5 and the communication device 6 do not directly perform voice communication, and the center device 4 relays voice communication between them. Then, the center device determines the communication permission time based on the priority of each of the communication devices 5 and 6, and when the call permission time elapses, the communication connection between the communication device 5 and the communication device 6 is disconnected and the call is performed. End.

  FIG. 9 is an operation sequence diagram of communication connection processing of the communication device 5, the communication device 6, and the center device 4 in the security system 1 according to the fourth embodiment. In this operation sequence diagram, in order for the security officer who confirms or copes with the security device 2 to communicate the emergency requirement, the communication device 5 communicates with the communication device 6 possessed by other security personnel via the center device 4. An example of making a call will be described.

First, when making a call to the communication device 6, the communication device 5 transmits a call request to the center device 4 (step S701). This call request includes the telephone number of the communication device 5 that is identification information of the communication device 5 and the telephone number of the communication device 6 that is identification information of the communication device 6.
When the center apparatus 4 receives the call request from the communication apparatus 5, the center apparatus 4 returns an incoming call response to the communication apparatus 5 (step S702). When this incoming call response reaches the center apparatus 4, a call connection is established between the communication apparatus 5 and the center apparatus 4. Next, the center device 4 transmits a call request to the communication device 6 designated as the call destination (step S703).
When receiving a call request from the center device 4, the communication device 6 returns an incoming call response to the center device 4 (step S704). When this incoming call response reaches the center apparatus 4, a call connection is established between the communication apparatus 5 and the center apparatus 4.
Thereafter, the center device 4 artificially connects the communication connection with the communication device 5 and the communication connection with the communication device 6, and receives the voice data received from the communication devices 5, 6 as the communication device on the other side. Transfer processing to transfer to 5 and 6 is executed (step S705). As a result, a call can be made between the user who possesses the communication device 5 and the user who possesses the communication device 6.

  Next, the center device 4 refers to the user table and the time table, and the priority and communication possible time associated with the identification information of the communication device 5 and the priority and communication associated with the identification information of the communication device 6. Based on the possible time, a communication permission time determination process for determining a communication permission time is performed (step S706). This communication permission time determination process is the same as the communication permission time determination process shown in FIG.

The center device 4 measures the time until the communication permission time determined in the communication permission time determination process elapses after the relay of voice communication between the communication device 5 and the communication device 6 starts (step S707). When elapses, the audio data transfer process is terminated, and the pseudo communication connection between the communication devices is disconnected (step S708).
Then, the center device 4 transmits a disconnection request to the communication device 5 (step S709).
The communication device 5 that has received the disconnection request returns a disconnection response to the center device 4 (step S710). Thereafter, the communication connection between the communication device 5 and the center device 4 is disconnected.
The center device 4 transmits a disconnection request to the communication device 6 (step S711).
The communication device 6 that has received the disconnection request returns a disconnection response to the center device 4 (step S712). Thereafter, the communication connection between the center device 4 and the communication device 6 is disconnected.

  Next, details of the communication device 5 according to the fourth embodiment will be described. In addition, since the structure of the communication apparatus 5 and the communication apparatus 6 is the same, below, the communication apparatus 5 is demonstrated as a representative. The configuration of the communication device 5 according to the fourth embodiment is partially different in the functions of the storage unit 54 and the control unit 55 among the units of the communication device 5 according to the first embodiment shown in FIG.

In the fourth embodiment, since communication center time 4 is determined based on priority, the center device 4 does not store information on priority and communication time for each of the communication devices 5 and 6. May be.
When making a call, the control unit 55 transmits a call request including identification information of the communication device 6 on the receiving side to the center device 4. Further, when a call request is received from the center apparatus 4 at the time of incoming call, an incoming call response is transmitted to the center apparatus 4.
In addition, the determination unit 552 does not determine whether or not the communication permission time has elapsed, and disconnects communication according to a disconnection request from the center device 4.

  Next, details of the center device 4 according to the fourth embodiment will be described. The configuration of the center device 4 according to the fourth embodiment is partially different in functions of the IP communication processing unit 42 and the control unit 46 among the respective units of the center device 4 according to the first embodiment shown in FIG.

The IP communication processing unit 42 further includes an interface circuit for performing IP telephone communication according to a protocol such as SIP. And the IP packet of the audio | voice data which the communication apparatus 5 transmitted via the gateway server is received, and it transfers to the communication apparatus 6 via a gateway server. Also, the IP packet of the voice data transmitted from the communication device 6 via the gateway server is received and transferred to the communication device 5 via the gateway server.
In addition, the IP communication processing unit 42 transmits the call request, the incoming call response, and the disconnection response received from the communication device 5 or the communication device 6 via the IP network 11 to the control unit 46. Further, the IP communication processing unit 42 transmits a call origination request, an incoming call response, and a disconnection request to the communication device 5 or the communication device 6 through the IP network 11 according to the control of the control unit 46.

  In addition to the setting unit 461 and the determination unit 462, the control unit 46 has a relay function for executing processing for transferring voice communication between the communication device 5 and the communication device 6. When receiving a call request from the communication device 5, the control unit 46 transmits an incoming call response to the communication device 5 via the IP communication processing unit 42 and transmits a call request to the communication device 6 designated as the call destination. . Then, when the incoming response is received from the communication device 6, the IP communication processing unit 42 executes the transfer process to artificially connect the voice communication between the communication device 5 and the communication device 6, and is received from the communication device 5. The voice data is transferred to the communication device 6, and the voice data received from the communication device 6 is transferred to the communication device 5.

When the communication device 5 is connected to the communication device 6, the determination unit 462 determines a communication permission time for voice communication between the communication device 5 and the communication device 6. The determination unit 462 reads the priority associated with the identification information of the communication device 5 and the priority associated with the identification information of the communication device 6 with reference to the user table stored in the storage unit 43, Compare priorities. Then, the determination unit 462 refers to the time table in the storage unit 43, reads out the communicable time set for the higher priority among the priorities of the communication device 5 and the communication device 6, and permits communication for this time. Decide as time.
In addition, the determination unit 462 measures the time since the communication connection between the communication device 5 and the communication device 6 is started, and the sound between the communication device 5 and the communication device 6 when the determined communication permission time has elapsed. The communication relay of communication is terminated and the call state between the communication devices is disconnected, and a disconnect request is transmitted to the communication device 5 and the communication device 6 to disconnect communication with the communication device 5 and the communication device 6.

  As described above, in the communication system according to the fourth embodiment, the center device is connected to each of the two communication devices and relays the audio signal between the communication devices, and the priority of each communication device is set. The communication permission time is determined based on this. When the call permission time elapses, the relay of the audio signal between the communication devices is ended, and the call state is disconnected. Thereby, the communication apparatus can suppress an inadvertent long-time call within a range that does not hinder business, as in the first embodiment.

In the security system of the fourth embodiment, the same changes and modifications as in the first embodiment are possible.
The configuration of the second embodiment can also be applied to the fourth embodiment.

  Thus, those skilled in the art can make various changes in accordance with the embodiment to be implemented within the scope of the present invention. For example, in the first to fourth embodiments, a communication device owned by a security guard who is outdoors and a communication device possessed by a security guard who is outdoors, or a center device and a security guard outdoors. However, the present invention may be applied to a resident service in which a guard is resident in the facility. For example, between a disaster prevention headquarters installed in the same building as a communication device owned by a security guard who monitors a suspicious person at a predetermined place such as an entrance / exit in a building or visits a predetermined place in the building It may be applied to other communication connections. In this case, a center device is installed in the disaster prevention headquarters, and a more appropriate communication method is selected.

  In each of the embodiments described above, the example in which the call time is limited according to the priority of the communication device on the incoming side or the outgoing side has been described, but 110 (Police), 118 (Coast Guard), 119 With the exception of so-called emergency special numbers such as numbers (firefighting), long-term calls can be made unconditionally.
