Description

DETAILED DESCRIPTION OF THE INVENTION [Outline] The telephone number (hereinafter, referred to as a telephone number) of a transfer destination subscriber that has already been registered is collated by a dial operation of the subscriber and notified to the subscriber.

[Industrial applications]

The present invention relates to a call transfer service of a telephone exchange, and more particularly to a call transfer service capable of performing call transfer registration regardless of presence / absence of a transfer destination subscriber and confirming that the subscriber is correctly registered. Is.

[Conventional technology]

In the conventional call transfer service, there were two methods in the procedure for registering transfer.

One of them is a method in which the registrant dials the telephone number of the transfer destination subscriber together with the special number for the call transfer registration, and the transfer destination subscriber confirms the transfer destination by responding and then executes the transfer registration. .

The other is that when the registrant dials the telephone number of the transfer destination subscriber together with the special number for call transfer registration, the exchange side simply does not respond to the transfer destination subscriber and there is a contradiction in the allowable service of the subscriber. It is a method to execute registration immediately after checking that there is no such information.

[Problems to be solved by the invention]

In the first method above, when registering a call transfer, it will be registered after contacting the transfer destination, so errors in the transfer destination can be prevented.
There must be a person who responds to the forwarding destination, and when the other party is absent, there is an inconvenience that the person cannot respond because he cannot respond.

On the other hand, in the second method, the transfer destination dialed by the registered subscriber is unilaterally registered on the exchange side, so that there is a drawback that the error is not noticed until the call transfer is actually performed.

Therefore, an object of the present invention is to provide a call transfer method capable of registering a call transfer regardless of whether the transfer destination is present or absent and further confirming that the subscriber is correctly registered.

[Means for solving problems]

In the switching system, when the telephone number of the transfer destination subscriber is entered to register the call transfer from the first terminal, the first terminal is the terminal of the subscriber who is permitted the call transfer service. After confirming that the telephone number of the transfer destination subscriber is not registered, confirm that the second terminal to which the input telephone number of the transfer destination subscriber is given is accommodated in the exchange system. If confirmed, the input transferee subscriber's telephone number is stored and a call transfer state for transferring an incoming call to the first terminal to the second terminal is set. And a means for notifying the first terminal of the end.

[Action]

The terminal that entered the transfer destination subscriber's telephone number to register the call transfer is the terminal of the subscriber who is permitted the call transfer service, and the transfer destination subscriber's phone number is not registered. If it is confirmed that the terminal having the input transfer destination subscriber's telephone number is accommodated in the switching system, the terminal that registered the call transfer is set to the call transfer state. Call forwarding can be registered regardless of the presence / absence of the forwarding destination subscriber.

If the subscriber who registered for call forwarding confirms the call forwarding destination already registered, dial the special number for registration confirmation and the telephone number of the call forwarding destination subscriber, and the telephone exchange will register the call forwarding destination already registered. The subscriber's telephone number is compared with the telephone number of the call transfer destination subscriber entered for confirmation this time, and if there is a match, information that can identify the match is notified by, for example, a confirmation sound. The person can confirm whether or not the telephone number of the registered call transfer destination subscriber is incorrect.

〔Example〕

In the call transfer method according to the present invention, the registration procedure and the confirmation procedure are separated so that registration can be made regardless of whether the transfer destination subscriber is present or absent.
The registration result can also be confirmed.

FIG. 1 is a diagram for explaining a call transfer method according to the present invention.

FIG. 2 is a flowchart of the call transfer registration process according to the present invention.

FIG. 3 is a flowchart of registration confirmation processing according to the present invention.

In the figure, 1 is a network, 2 is a main control device, 3 is a main storage device, 4 is an auxiliary storage device for registering registered telephone numbers, 5 is a confirmation sound source, 6 is a calling sound source, 10 is a switch according to the present invention, A,
B and C are terminals, respectively.

The registration and confirmation will be explained in detail below. For convenience of explanation, the terminal will be mainly described by the operation of the subscriber who uses the terminal. Subscribers A, B, and C described below are subscribers who are users of terminals A, B, and C, respectively.

(A) In the case of registration In FIG. 2, the storage contents of the main storage device 3 or the auxiliary storage device 4 are shown on the left side, the processing of the main control device 2 of the exchange 10 is shown in the center, and the control contents of the network 1 etc. on the right side. Are shown respectively.

First, the subscriber A dials the registration special number and the subscriber B's telephone number, and the exchange 10 receives the dial by a known means.

The main control unit 2 determines whether or not the subscriber A is a subscriber who is permitted the call transfer service by looking up the service permission / non-permission table SV.

If the subscriber A is not permitted to use this service, a busy tone or the like is sent to notify the subscriber A that the service is not permitted.

When the subscriber A is permitted to use this service, the transfer registration status of the subscriber A is read from the registration table REG,
It is checked whether the subscriber A has already registered the telephone number of the transfer destination subscriber.

If it has already been registered, the transfer destination subscriber is notified that it has already been registered in order to prevent double registration of the called party.

On the other hand, if the transfer destination subscriber's telephone number is not registered, subscriber A
The subscriber mounting table CM is checked by checking whether or not the subscriber B, which is the registration destination dialed by, is accommodated in the exchange 10.

When subscriber B is not installed, a busy tone or the like is sent to notify that effect. Subscriber B when implemented
The telephone number is written in the registration area of the subscriber A and registered, and a transfer registration confirmation sound is sent to the subscriber A.

Subscriber A knows that transfer registration has been performed by hearing this confirmation tone.

Thereafter, the call received by the subscriber A is transferred to the transfer destination subscriber B.

Since the above operation is the same as the second method described in the section of the prior art, the subscriber A intends to dial the special number for registration and the telephone number of the transfer destination subscriber B. Suppose that the telephone number of subscriber C is dialed without noticing it.
In this case, the call received by the subscriber A is transferred to the subscriber C to cause an erroneous call, and as a result, the caller and the subscriber C are annoyed, as described above.

The subscriber A confirms the registration operation in order for the subscriber A to confirm and eliminate such a malfunction.

(B) Confirmation of registration In FIG. 3, as in the case of FIG. 2, the stored contents of the main storage device 3 or the auxiliary storage device 4 are shown on the left side, the processing of the main control device 2 of the exchange 10 is shown at the center, and the network is shown on the right side. The control contents such as 1 are shown respectively.

Subscriber A is a special number for confirmation of call transfer service and subscriber B
The telephone number is dialed and the exchange 10 receives this dial by a known means.

The main control unit 2 determines whether or not the subscriber A is a subscriber who is permitted the call transfer service by looking up the service permission / non-permission table SV.

If the subscriber A is not permitted to use this service, a busy tone or the like is sent to notify the subscriber A that the service is not permitted.

When the subscriber A is permitted to use this service, the transfer registration status of the subscriber A is read from the registration table REG.

If the transfer destination is not registered, the exchange process is performed as in the normal outgoing call, and the process shifts to the process of calling the subscriber B.

When the forwarding destination is registered, the telephone number dialed by subscriber A after the confirmation special number is compared with the telephone number written in the registration area of subscriber A to check whether they match. .

If they do not match, normal call exchange processing is performed, and if they match, the transfer registration confirmation sound source 5 is connected to the subscriber A via the network 1 and a confirmation sound is sent to the subscriber A.

Subscriber A can confirm that he / she has been registered correctly by hearing this transfer registration confirmation tone, and when he / she hears the normal ringing tone, he / she knows that he / she has been mistakenly registered. ) Perform the registration operation described in the case of registration to correct it.

〔The invention's effect〕
