20j is a base station (BSS) provided for each area (cell) of h to j, and 21h to 21j are each area h to h.
A mobile terminal (MS) held by a patrol car or a security officer currently located in j, 22 is a small terminal (MS0) that generates a signal for requesting rescue, and 23h to 23j are Bs.
No. which is a CCITT standard between the SS and the mobile service exchange. 7 signal system (SS7 protocol: Si
gnaling System no.7) transmission line for communication, 24
Is a mobile service switch (MSC) that is connected to a plurality of BSSs to perform a switching service, and 25 is a voice response device (VR).
E: Voice Response Equipment), 26 is NO. A transmission line for performing communication by the 7-signal system, 27 is a service control device (SCP) that provides data and control information for realizing a service in response to a request from each MSC 24.

Reference numeral 27a in the SCP 27 is a central controller (CC) 27 for performing program control.
b is a main storage device (M
M: Main Memory), 27c is a file device that stores a database corresponding to the service, and 27d is a common channel device (CSE: Common channel Signaling Equipment) that processes the SS7 protocol and performs mutual communication with the MSC 24.

The processing sequence according to the present invention in the system shown in FIG. 2 is shown in FIGS. FIG. 3 is a processing sequence of management information of a mobile terminal, FIG. 4 is a processing sequence of patrolling, and FIG. 5 is a table configuration example.

When the vehicle on patrol in each area shown in FIG. 3 or an MS carried by a person is moving (or stopped), position information (cell number of the BSS of the BSS that is periodically transmitted from the surrounding BSS by radio) ) Is received (a in FIG. 3). Each MS
Receives the signals from multiple BSSs, determines the position information with the highest reception level, determines it as the current position, adds its own MSID (MS identification number) to the cell number, and returns it to the BSS. (B in FIG. 3). Each BSS
When this location registration information (cell number + MSID) is received, a special number (special number for instructing location registration) is added to this and transferred to the MSC 24 (c in FIG. 3). The MSC 24 further notifies the SCP 27 of the same content using the SS7 protocol (d in FIG. 3).

When the SCP 27 receives the CSE 27d, the SCP 27 notifies the CC 27a. When the CC 27a determines the special number, the main memory 27b (or the file device 27).
Register the contents of the in-cell MS management table provided in c).

An example of the configuration of the in-cell MS management table is shown in FIG. Table 2 below. This table stores the information related to the MS (mobile terminal) existing in the cell in the area assigned to each cell number,
The number of initially existing MSs is 50, and an announcement parameter (A-
MS numbers (MSID) such as PRMi, i are constants 51, MSa52, MSb53 are stored. According to FIG. 3, when the SCP 27 receives the cell number and the MSID together with the special number, the M in the area of the corresponding cell number in this table
Register (update) the SID. That is, if it has been stored before, it is retained as it is, and the newly generated MSI
D is newly stored, and the MSID that was previously registered and does not respond this time is deleted.

Next, the processing sequence for activating the patrol will be explained with reference to FIG. 4. When a person carrying the small terminal 22 presses a button for requesting rescue when an emergency situation such as a crime occurs, the small terminal 22 is previously operated from the small terminal 22. The determined special number is transmitted wirelessly (a and b in FIG. 4). This radio signal is received by the BSS in the area at the strongest reception level. Upon receiving this, the BSS 20 adds its own cell number (representing the area where the small terminal exists) to the special number and transmits it to the MSC 24 (c in FIG. 4).

When the MSC 24 receives this, it is triggered by determining the special number and starts the operation of accessing the SCP 27. Access to SCP27 is SS7
Transaction processing protocol (called TCAP: Transaction Capability Application Protocol)
The special number and the calling cell number are notified by the request message (REQ) (d in FIG. 4).

The SCP 27 is provided with an adjacent cell number table as an adjacent cell determination table corresponding to the number of the cell (BSS) transmitted to the BSC by receiving the special number from this small terminal. A of FIG. Table 1 below. In this example, it is shown that the cell j, the cell k, etc. are adjacent cells to the calling cell number (i). The SCP 27 determines and transmits the content of the instruction message to the MSC 24 by the logical processing flow of FIG. 6 described later using the adjacent cell determination table and the intra-cell MS management table shown in FIG. 5 (e in FIG. 4).

[0021] The play announcement sent (PLAY
ANA) The message is the MS to which the announcement is sent.
(Patrol Mobile Terminal) Number and Announcement
It is composed of a message ID. In the example of FIG. 4, [MS2, ANA, A-PRM] is added as the parameter.

The MSC 24 receiving this message,
When an incoming call is made to the mobile terminal included in the parameters to make a call (f in FIG. 4), and a vacant call channel is hunted and captured when there is a response, a mobile object such as a patrol car is sent via the call channel. Terminal MS and voice response device 25
Connect them (g, h in FIG. 4). In addition, MSC24,
The received announcement message ID and the announcement parameter (A-PRM) are output to the voice response device 25 to instruct generation of voice (i in FIG. 4). As a result, the announcement message (voice) having the ID designated by the voice response device 25 can be sent to the mobile terminal MS and heard by the person in charge.

FIG. 6 is a flow of logical processing in the service control unit (SCP). In FIG. 6, MSC24
When the request message (REQ.MSG) is received from S1 (S1 of FIG. 6), the program to be started is determined by the special number (S2 of the same). In this case, since it is a special number that requires patrol activation processing, the corresponding program is activated. Then, according to the calling cell number (cell i), the table 1 (see FIG.
A. ) Is indexed to determine up to 6 neighboring cells (S3 in FIG. 6). The table 2 (B. in FIG. 5) is indexed by the determined neighboring cell and originating cell numbers (ID), and the presence / absence of MS in each cell is checked (S4 in FIG. 6).

As a result, the pattern of the patrol activation logic is determined (at step S5). An example of each patrol activation logic corresponding to each pattern will be described later with reference to FIG. 7. The instruction announcement for each MS in each cell is determined (at step S6). A specific example of the instruction announcement by the patrol activation logic will be described later. Next, a play announcement message corresponding to the determined instruction announcement is generated (S7 in FIG. 6).

FIG. 7 shows an example of the structure of a basic cell. In the figure, when the small terminal MS0 that has issued the alarm is in the area of the cell 0 (BSS), the cell that issued the alarm is the cell 0. The basic cell configuration is such that six cells are arranged adjacent to each cell, and FIG. 7 shows only adjacent cells 1 to 6 centered on cell 0. In this case, cell 0 is an example in which a certain area is located in the 1-chome area, cell 1 is located in the 2-chome area, ...

FIG. 8 shows an example of the patrol activation logic corresponding to each pattern in such a basic cell configuration. As shown in FIG. 8, in the case of pattern 1, there is a patrol MS only in the originating cell (cell 0) and there is no patrol MS in adjacent cells 1 to 6, and the patrol invocation logic at this time is used. Is M in the originating cell
The content is such that S1 is assigned to the patrol in the originating cell and the other MSs in the originating cell are assigned the patrols of cells 1 to 6. In pattern 2, when there are MSs in adjacent cells in addition to the originating cell, pattern 3 has no MSs in patrol in the originating cell and Ms in patrol only in adjacent cells.
In the case where there is S, each is determined as shown in the figure.

The actual activation of each patrol to the MS is performed by giving an announcement message, and the announcement sent from the SCP to each MS can be flexibly changed by the data definition of the SCP. That is, the announcement message ID and announcement parameter of the MS corresponding to each activation logic pattern are defined.

As described above, the announcement message ID and the announcement parameter are determined, and the play announcement message is sent from the service control unit (SCP 27 in FIG. 2) to the mobile service exchange (MSC 24 in FIG. 2). The MSC 24 sends the instructed announcement to the instructed MS.

An example of this announcement will be described below. In this example, as shown in FIG. 7, the MS1 of the patrol exists in the cell 0, which is the originating cell, and the cell 1, which is the adjacent cell,
When there are patrol MS2 and MS3 in the cell 5, respectively, the mobile service exchange (MSC2 in FIG. 2)
4) From the voice response device (VRE25 in FIG. 2) to each MS1
~ The following announcement is sent to MS3.

MS1: "Crime occurrence in 1-chome area, patrol the 1-chome area" MS2: "Crime occurrence in 1-chome area, patrol the 2-chome area, 3-chome area" MS3: "1-chome area" Crime occurrence in the district, please patrol the area from 4-chome area to 7-chome area ”Next, a small terminal carried by an individual in case of a crime occurrence (Fig. 2
FIG. 9 shows a configuration example of No. 22).

In FIG. 9, the transmission unit 2 is provided in the small terminal 22.
2a, microprocessor (MPU) 22b, memory 2
2c, a press detection unit 22d, and a button 22e are provided. To explain the operation, when the button 22e is pressed, an output is generated from the pressing detection unit 22d and the MPU 22b is activated. The MPU 22b operates according to a program in the memory 22c, activates the transmission unit 22a, and subsequently supplies the special number data from the memory 22c to the transmission unit 22a, and transmits the special number from the transmission unit 22a according to a predetermined protocol. This transmission can be repeated a fixed number of times.

As described above, since the small terminal carried by an individual has a simple function, the device can be downsized and can be reliably operated even in an emergency such as a crime because a button is simply operated. . The present invention can be applied to applications other than crime, for example, to always confirm the whereabouts of an individual and issue a necessary instruction to a mobile terminal.
