As a method for automatically transferring calls when the other party is not present, there is a known method, for example, as described in Japanese Unexamined Patent Publication No. 10961/1984, in which the person's current location is registered each time using the destination phone. .

[Problem to be solved by the invention]

According to the above-mentioned conventional technology, since the transfer is performed only to the registered terminal, there is a problem that if the registration is forgotten, the transfer cannot be performed or the transfer is performed to the previously registered location.

An object of the present invention is to solve the above problems by sequentially transferring information to possible destination terminals.

[Means to solve the problem]

The above object is achieved by a user of a telephone terminal recording in advance a list of telephone numbers of places he/she often goes to on the terminal, and the exchange searching for the user in accordance with the list.

[Effect]

A storage device in a telephone terminal is provided with means for registering a plurality of telephone numbers of places frequently visited by a user of the terminal. When the exchange detects that the called party is not present at the terminal, the exchange requests the terminal to transfer the destination phone number list registered for each user to the exchange, and when the transfer is completed, the destination phone number registered for each user is transferred to the exchange. A search for an absent person is performed by sequentially calling the terminals of the number.

If the user leaves the original location using the above method,
You can now transfer calls without having to register your destination in the switchboard.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an example of the configuration of a network system to which the present invention is applied. 1 to 4 are telephone terminals each having a display device, a storage device, a keyboard, and a microprocessor;
It is connected to the. The subscriber line 11 has an I5DN (Integrated Service Digital Network) basic interface, and a user information channel and a control information channel are provided independently. Also, among telephone terminals 1 to 4, 1 represents the calling terminal and 2 represents the called terminal. A destination list 2o is stored therein.

The destination list 20 has the format shown in FIG.
It has the following information.

(1) User name 21: Name of the user targeted for the destination list.

(2) Destination phone number 22: Phone number of the place where the above user often goes.

(3) Number of discoveries 23: This is the number of times the user was found as a result of calling the user using the telephone number, and is updated by the exchange 10.

In (2) and (3) above, n pieces can be registered in the destination list, and the destination list can have m sides in the storage device (the values of n and m are (depending on storage device size). In the example of FIG. 1, telephone terminals 3 to 4
represents the terminal registered with the destination telephone number in the destination list.

FIG. 3 is a diagram for explaining the procedure of a service to which the present invention is applied. Transmission and reception of each signal in FIG. 3 is performed using a control information channel on the subscriber line 11.

The operation of the system of the present invention will be explained below with reference to FIGS. 1 to 3.

The originating terminal] sends the outgoing signal to the exchange 10 by adding the telephone number and name of the other party (this information is entered by the user of the originating terminal 1 from the keyboard). . The exchange 10 analyzes the telephone number in the outgoing signal and transmits a calling signal with the name of the other party added to the called terminal 2.

The destination terminal 2 displays the name of the other party on the display device along with the ringing of the call.

A user close to the destination terminal sees the display and, if the corresponding user is absent, returns a negative signal to the exchange 10 by pressing a key on the keyboard, and the exchange 10 forwards it to the origination terminal. do.

The calling terminal 1 displays a message that the other party is absent on the display and waits for the user's action. When the user inputs a call forwarding service request using the keyboard, the calling terminal 1 transmits a service request signal with the name of the other party to the exchange 10.

The exchange 10 extracts the name of the other party from the service request signal, adds it to the destination list request signal, and transmits it to the destination terminal 2. The destination terminal 2 searches whether a destination list corresponding to the name of the called party that has been sent is registered in its own memory, and if it is registered, adds the destination list to the destination list transfer signal. , is transmitted to exchange 1-0.

In accordance with the contents of the received destination list, the exchange 10 transmits a calling signal with the name of the communication partner added to the terminals registered in the destination list in descending order of the number of past discoveries. Sends a call destination display signal with a call destination telephone number attached. The originating terminal displays the called telephone number in the received signal on a display device to inform the originating user of which terminal is currently being called.

The first called terminal 3 operates in the same way as the called terminal 2 described above, and if the user near the terminal 3 is absent, the user corresponding to the name displayed on the display device will deny the call. The signal is returned to the exchange 10. Next, if the called party of the calling terminal 1 is near the called terminal 4, the user inputs an affirmative response from the keyboard and transmits an affirmative signal to the exchange 10.

Upon receiving the affirmative signal from the terminal 4, the exchange 10 counts up the number of discoveries corresponding to the telephone number of the terminal in the destination list 1~, adds the updated destination list to the destination list transfer signal, and sends the destination list to the destination list. At the same time, an affirmative signal is sent to the originating terminal 1, and the originating terminal 1 and the terminal 4 are connected.

According to the above procedure, even if the other party is not near the telephone terminal that first received the call, the exchange automatically searches for the other party and communication is possible.

〔Effect of the invention〕

According to the present invention, even if a user of a telephone terminal forgets to register his or her destination in an exchange when moving, the exchange searches for the user according to the destination list, so that the user can be transferred to the destination. There is.
