Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a telephone device such as a private branch exchange.

(Prior art) Conventionally, in a horizontal switching system, for example, for services such as extension service, central line calling, leased line calling, etc., the maximum number of requests for such services is determined, and therefore terminal groups are Each class was divided into classes, and each class had its own priority order.

For example, if all the central office lines are blocked and there is a request to make a central office line call from an A class extension telephone and a B class extension telephone, the processing order will be determined based on the preset priority order of the A class extension telephone and the B class extension telephone. Determined - CI.

However, the extension telephone belonging to each class (Ikugen ())
4. Since the processing order is determined in advance, many calls occur (
In cases where there are only two telephones, a problem arises in that service to extension telephones used by VIPs in each class is overloaded and delayed.

(Problem to be solved by the invention) As mentioned above, in conventional telephone devices, the number of receptions for a given service is fixed. As a result, problems such as delays in service to telephone extensions used by VIPs in each class occurred.
It lacked attentive service.

The present invention was made in view of the problems of conventional telephone devices, and its first purpose is to enable processing of services based on priority for each extension telephone. The present invention is to provide a telephone device that can improve the order of service processing for extension telephones.

[Structure of the Invention] (Means for Solving the Problems) In the present invention, when a predetermined number of extension telephones receives a request for a predetermined service at one time, the extension telephones exceeding the predetermined number are placed in a waiting state and the corresponding The telephone device that responds to the request includes priority registration means in which data regarding the processing priority of extension telephones for the service is registered, and a processing order for extension telephones exceeding the predetermined number among the extension telephones that have requested the service. Process to keep 1
n storage means; When a request for the service is received from an extension telephone, it is detected whether the number of requests exceeds a predetermined number, and if the number exceeds a predetermined number, the processing priority of the extension telephone in the priority order registration means is determined. The telephone device is provided with processing order control means for changing the processing order in the processing order storage means based on data regarding the processing order.

(Function) According to the above configuration, the processing priority data of extension telephones is registered in the priority registration means, and when a service request from an extension telephone with a high processing priority is in a waiting state, the processing order is stored. With a high processing order within the means! Waiting time can be shortened.

(Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 2 is a block diagram of a private branch exchange according to an embodiment of the present invention. In the figure, 1 is from the switch network. The switching circuit 1 is controlled by the control unit 8 and is connected between the extension circuits 31 to 3. and between the extension circuits 31 to 3. and the central office line circuits 51 to 51 to "Ill" or the dedicated line circuits 71 to 7. Connect between.

The extension circuits 3-3 have extension telephones 21-2. are connected to the station line circuits 51-5m, stations t441-41Il are connected to the station line circuits 51-5m, and dedicated lines 61-6. are connected to the dedicated line circuits 71-7o. is connected. The control unit 8 is configured as a microcomputer and processes calls made and received on the line based on its own program.

The extension circuit 3 has an interface function between the extension telephone 2, the exchange circuit 1, and the control section 8. The office line circuit 5 and the leased line circuit 7 are controlled by the control section 8 to perform call processing, transmit incoming calls to the control section 8, and transmit voice signals and the like between the switching circuit 1 and the line. has. Connected to the control unit 8 are a storage unit 9 that stores data on processing priorities, etc., and a maintenance terminal 10 for registering various operational data and the like.

In the private branch exchange as described in 2 above, the control section 8 and the storage section 9 function as a priority registration means 101, a processing order storage means 102, and a processing order control means 103 shown in FIG. Priority order registration means 101 has registered therein data of processing priorities relating to predetermined services for each extension telephone. Registration of this data is determined as an error from the maintenance terminal 10. The control means 103 sets the 1 flag 104 to indicate whether or not it is ready to receive a request for a predetermined service, and when a request for the service is required from the extension telephone 2, When Louis checks the flag and confirms that he is in a state where he can accept the request, he immediately starts processing the request. On the other hand, if the flag 104 indicates that he cannot accept the request, he calls the extension number related to the request. Data on the processing priority of the telephone is retrieved from the priority σ record means 101 and the processing order storage means 102
The identification information of the extension telephone and the data of its processing priority are compared with the data of the processing priority of the extension telephone in the waiting state, and the identification information of the extension telephone and the data of its processing priority are registered in the position of the corresponding order. When the service to the extension telephone receiving the service is completed, the control section 8 refers to the processing priority data in the processing order storage means 102 and starts the service to the extension telephone having the highest priority.

Next, the case of calling from a central office line will be explained. Here, processing within a certain class will be shown, and the relationship with other classes will not be considered because they are not directly related to the present invention.

FIG. 3 shows a memory map within the priority registration means 101. This indicates that extension telephones with extension numbers for which the 1oYES flag is set are treated preferentially. Furthermore, YES
If there is more than one, it will be on a first-come, first-served basis. FIG. 4(a) shows a memory map within the processing order storage means 102 at a certain point in time. Here, it is assumed that the office line assigned to the same class is blocked by the station's extension telephone and is in a call waiting state.

Then, the extension telephone with extension number r2003J [2oo1j is in a standby state.

On the other hand, the control unit 8 performs control over the central office line call according to the program for flowchart 1 shown in FIG.
There is. That is, when the power is turned on, it becomes a star, data is fetched (501), and when it detects that it is necessary to make a call to the central office line (502), it refers to the flag 104 and detects whether there is an empty central office line. 503), and if there is an empty office line, the relevant trunk (inside the office line circuit 5) is captured and a call can be made (504). If there is no open station line, processing order storage means 1
Detects whether 02 is full (can accumulate a queue) (50
5). Here, if it is full, a busy tone is sent to the extension telephone that made the call request (506), and if it is not full, the priority order registration means 101 is referred to and the extension telephone that made the call request is sent 506). It is detected whether a YES flag is set (507). If the YES flag is not set to cell 1, the identification information is stored at the beginning of the empty area in the processing order storage means 102 (508). On the other hand, if the YES flag is set, the Y
The identification information of the extension telephone and the YES flag are registered in the area before the identification information without the ES flag (509).

After this operation is performed, if a request to make a call to the central office line is received from the extension telephone with extension number 2100J in the state shown in FIG. 4(a), the extension number r21
The processing order for extension telephone 00J is registered first. When the central office line becomes vacant, the extension telephone with extension number "r21oo" is called, and when the telephone goes off-hook, control is performed so that the central office line is captured.

In this embodiment, the data regarding the processing priority (\ES flag) may be stored in the processing order storage means 102, or the registration order may be changed by referring to the priority order registration means 101 without storing this data. . Furthermore, the storage area of the registered data in the processing order storage means 102 was changed using the so-called FIFO method.
Data showing the processing order In FIG. 4, it is not necessary to change the ordinal number on the left side to change the storage area of the identification information of the extension telephone.

Furthermore, the data regarding the processing priority is not limited to something that only indicates priority, such as a YES flag, but may also be something that indicates the priority itself, such as NO1, NO2, etc.

[Effects of the Invention Song Dynasty 1 As explained above, according to the present invention, the priority registration means records data on the processing order of extension telephones,
