Abstract

PURPOSE:To surely telephone a required destination by executing the service, which is executed whichever destination a call comes from, only for the incoming call from a preliminarily designated destination. CONSTITUTION:When a call with a register source extension as the incoming destination comes in the registered state, the telephone number of an originating subscriber and that of a terminating subscriber are inputted to a controller and it is discriminated whether they are registered for the terminating system service or not. When they are registered, it is discriminated whether an execution condition based on the destination number is registered or not to discriminates whether the service should be executed or not. When a flag indicating whether register is effective or ineffective is set to '0' to indicate that register is ineffective, the terminating system service is not executed, and the call is terminated in the original incoming destination. When the flag is set to '1' to indicate that register is effective, the terminating system service is executed, and the connection processing to transfer the call to the registered transfer destination is performed.

Description

[Detailed Description of the Invention] [Summary] Regarding a terminating service control method of an exchange that executes a terminating service registered in advance by the terminating subscriber for an incoming call, the terminating service is provided only for a specific incoming call. The purpose of the present invention is to provide a terminating service control method for an exchange that can perform the above, and the switching processing device includes a registration unit and a service processing unit, and the registration unit detects a registration source in response to a registration request for a terminating service. detects the registration source, and when the forwarding destination reception means receives the calling number and the forwarding destination number, the registration means registers it in the incoming call service table in the memory, and the service processing section is activated by the incoming call and starts the calling/transferring number.
When the calling/terminating number is received by the called number receiving means, the calling service table search means is searched, and when the calling number of the incoming call is registered in advance by the registration section of the called number, the forwarding destination connecting means performs a transfer connection. Configure it to do so.

[Field of Industrial Application] The present invention relates to a terminating service control method for an exchange that executes a terminating service registered in advance by a terminating subscriber in response to an incoming call.

In recent years, various connection services have been provided as incoming call services in telephone exchange technology.For example, there is a service that transfers an incoming call to one's own telephone to another pre-registered telephone.

In the case of incoming calls like this, conventionally, the registered service is executed in the same way for any incoming call from any party, so even for incoming calls from parties that do not originally need to perform the service, it is the same for all incoming calls. The service is performed as follows:
Improvement is desired.

[Prior Art] In a switching system, particularly in a premise configuration, there is a group representative service as a terminating service in addition to a variable call forwarding service that automatically transfers incoming calls to a registered extension. The service consists of a group of multiple phones (each with a phone number set) that are related to work, etc., and the phone number of one of the phones is registered as the group representative number. This service allows incoming calls made to the group representative to be received by other telephones within the group even when the parent extension line is busy.

A conventional technique for variable call forwarding service will be explained.

Conventionally, if a user registers a forwarding destination phone number from their telephone to the exchange before the user is absent, then when the user's telephone receives an incoming call, the processing device of the exchange will automatically send the registered forwarding destination to the exchange. detects and connects the incoming call to its destination,
call. This allows the user at the transfer destination to talk to the other party.

[Problems to be Solved by the Invention] As described above, in the terminating service in the conventional exchange, the service was performed for all incoming calls. For example, in the case of a call forwarding service, when a call arrives at the extension where the forwarding destination has been registered, all calls are forwarded to the extension of the forwarding destination. However, when all incoming calls are forwarded, calls from parties that should not have been forwarded (unnecessarily) are forwarded, and the user at the forwarding destination is burdened with answering the calls each time.

SUMMARY OF THE INVENTION An object of the present invention is to provide a terminating service control system for an exchange that can perform terminating service only for specific terminating calls.

[Means to solve the problem] FIG. 1 is a diagram showing the basic configuration of the present invention.

In FIG. 1, 1o represents the communication path of the exchange, 11 represents the exchange processing device, 12 represents the registration unit, 13 represents the service processing unit, 14 represents the memory, 121 in the registration unit 12 represents the registration unit detection means, and 122 represents the transfer unit. The first receiving means, 123, is a registration means;
In the service processing unit 13, 131 is a calling/terminating number receiving means, 132 is a terminating service table searching means, 133 is a forwarding destination connecting means, and 134 is a terminating destination connecting means.

In the present invention, by registering in advance the party (caller) that the user wants to perform the incoming call service, when an incoming call is received, it is determined whether the caller is the registered party. The incoming call service is executed only when the service is registered.

[Function] A large number of telephones (not shown) are housed in the communication path IO, and when a user of a certain telephone requests registration of a call receiving service and dials a specific number, the registration unit 12 of the exchange processing device 11 is activated. do. As a result, the registration unit detection means 121
detects the number of the telephone that requested registration (identified from the housing location of the calling telephone) and holds it as the registration number.Next, the calling number (recipient's telephone number) from which the user may perform incoming call services is detected. ) and the forwarding destination number (which is then received by the forwarding destination receiving means 122. Next, the registration means 123 stores the previously held registration source number, the received calling number, and the forwarding destination number in the memory 14. It is registered in the incoming call service table 141.

When there is an incoming call, the service processing section 13 is activated.

In this case, when there is an incoming call, the switching processing device 11 detects the number of the caller of the incoming call, and the switching device 11 detects the number of the caller of the incoming call,
(detected using the same method as at the time of registration) and the called destination number (detected by a dial signal receiver (not shown)) have already been detected, and the calling and called number receiving means 131 of the service processing unit 13 detects these numbers respectively. Uke is taken from the means and kept. Next, the terminating service table search means 132 operates to search the terminating service table 141 in the memory 14 . At this time, it is checked whether the received called number matches the number of the registration source in the table, and if it matches, it is included in the calling number registered by the registration source.
Check to see if the calling number held by 1 exists. If there is a match, the transfer is performed and the calling telephone is connected by the transfer destination connecting means 133 to the telephone of the transfer destination number registered in correspondence with the corresponding registration source in the incoming call service table 141.

If, in searching the incoming call service table 141,
If no match is detected, the terminating service is not executed and the terminating destination connection means 134 connects to the original destination telephone.

Note that the originating telephone number can be detected by detecting the accommodation position of the originating subscriber's line by the exchange and converting the accommodation position into a telephone number. In the case of an (Integrated Digital Service'IA) switching system, the calling number is always transmitted as a control signal to the called destination, so the calling number can be used to search the called service table.

[Embodiment] FIG. 2 is a block diagram of an exchange according to an embodiment of the present invention.
4 is a flowchart of the registration process of the embodiment, FIG. 4 is a flowchart of the execution process of the embodiment, and FIG. 5 is a flowchart of the process of the call forwarding service.

In the embodiment of FIG. 2, the configuration of a private branch exchange is shown, and in the figure, 20 is a line circuit, 21 is a network, 22 is a central office line trunk, 23 is a local trunk, 24 is a trunk for various signals, and 25 is a central control Equipment (denoted by CC), 26
represents memory.

The network 21 in Figure 2 accommodates telephones of many subscribers, each connected to a line circuit (indicated by LC), and the other connected to a trunk (office line trunk, local trunk, signaling trunk, etc.). has been done.

When the CC 25 receives a call from a subscriber, it detects the location of the calling subscriber and connects it to the signaling trunk. The dial from the originating subscriber is received on the signaling trunk, and the CC
25 detects the calling number and the called number. Using this basic function, the CC 25 performs processing related to incoming call services.

The registration operation will be explained using the registration processing flow diagram of the embodiment shown in FIG.

When a user who wants to receive incoming call service dials the special number assigned for registering incoming call service from his/her own telephone, the process of registering incoming call service starts (
Step 30). Next, it is determined whether or not the other party's number needs to be identified (Step 31).
Alternatively, the determination can be made by detecting whether or not there is a dial input from the user in response to an inquiry from the exchange when the incoming call service registration process is started.

If identification of the other party's number is not required, the telephone number (for example, the forwarding destination telephone number) used for the incoming call service that the user inputs (by dialing) as in the past is stored in the memory 26 (
It is registered in the incoming call service table shown in FIG. 2 (step 33). If identification of the other party's number is required, the execution conditions input by the user are registered in the incoming call service table (step 32). The contents of this execution condition are the number of the other party to be identified and the telephone number used for the service.

In addition, it is possible to register contents that have been registered in advance such as invalidating them or validating invalid contents. Step 32. Alternatively, the registration is completed by completing the process in step 33.

The memory 26 in FIG. 2 shows an example of a terminating service table registered in this way. In this example, two types of services, call forwarding and extension representative, are provided for each registration source extension ( For the user's extension number), the other party's number and execution conditions are stored. In other words, in the case of missed call forwarding, for the registration source extension 1111, the forwarding destination number is N234j, and the execution condition is that the other party's number is extension r5.
For 678J, the valid/invalid flag is invalid “0”
is registered, and the other party's number is r044゜777, IIIJ
(Incoming call from an outside line), valid "1" is registered. Other extension numbers are similarly registered for the call forwarding service. Similarly, in the case of extension representative, the execution conditions (the partner number and valid/invalid flag) for executing the extension representative service are registered for each registration section extension.

The service processing flow of the embodiment shown in FIG. 4 will be explained.

As explained above with reference to FIG. The number is input and it is determined whether there is a registration for the incoming call service (step 41).
.

This identification is performed by searching whether the input destination telephone number matches the registration source number in the terminating service table (FIG. 2).

If it is not registered, the telephone of the original destination number is called by normal connection (step 42); if it is registered, then it is determined whether the execution condition by the destination number is registered or not. (Step 43). This identification is performed by checking whether or not there is a condition for executing a service based on the called party's number by checking whether there is data in the called party's number column of the incoming call service table.

As a result, if it is found that the execution condition has not been registered based on the partner number, it is determined whether or not to execute the service next. In this case, there are no restrictions on the other party's number, but if the flag indicating valid/invalid registration is "0" indicating invalid, proceed to step 49 and do not execute the relevant incoming call service. , the call arrives at the original destination (same as step 42). In addition, the flag “
1", execute the incoming call service and perform connection processing to forward the call to the registered forwarding destination (step 50).
).

If it is determined in step 43 that there is an execution condition based on the other party's number, the telephone number of the other party of the currently incoming call is searched for in the incoming call service table (step 44).

As a result, if it is found that the incoming call is registered, a connection process is performed to forward the incoming call to the registered forwarding destination (step 46), and if it is not registered, the call is not forwarded and the call is received at the original destination. (Step 47).

Next, the processing flow of the embodiment of the call forwarding service shown in FIG. 5 will be described. Note that this flow shows an example in a private branch exchange, and the flow of execution processing is a simpler procedure than the processing in FIG. 4.

First, a complete request for registration of call forwarding is made from extension (A) by dialing a special number (step 51). Next, the number of the other party to whom the call transfer is to be performed is registered by dialing (step 52), and then the extension number of the transfer destination is registered (step 53). This completes the registration for the call forwarding service.
Each number is stored in a call forwarding service table (not shown), and then service execution processing is performed.

When there is a connection request, it is determined whether the extension of the connection destination (receiving destination) is a registered extension for call forwarding (step 55), and if it is a registered extension, it is determined whether the calling source (recipient) is the number of the call forwarding party. (Step 56). This step 5
The determination in step 5.56 is made by checking the above-mentioned call forwarding service table, and if NO in both steps 55.56, connection is made (to the original destination) according to the dial signal.

If it is found in step 56 that the calling party is registered as the call forwarding execution number, connection processing is performed to call the registered forwarding destination extension (step 57).

In this way, in the case of the variable call forwarding service, by registering the person who is supposed to receive the call at the time of registration, you can receive calls from other or previously unwanted calls without automatically forwarding them to the specified person. Only numbers can be forwarded automatically.

In addition, when registering an extension representative service, for example, when there are two business groups in the representative group, the service is executed only for the party number that is related to both,
If you do not want to perform this service for a party that is related to only one group, you only need to register in advance only the party numbers that are related to the two groups.

[Effects of the Invention] According to the present invention, a conventional incoming call service that is executed for any incoming call when there is an incoming call can be executed only for incoming calls from a pre-designated party. Since the service is not executed for incoming calls from unnecessary parties, it is possible to reliably make calls to necessary parties.
