The present invention relates to a subscriber information storage method.

In recent years, switching equipment and terminals have become more sophisticated, and an increasing number of terminals, including telephones, have display and storage functions. Along with this, as one way to improve the convenience of terminals, services are being provided that display the number of the other party's terminal, the name of the user, etc. on the terminal.

In order to display subscriber information such as the terminal number and user's name on the terminal, in conventional switching systems, the subscriber information is stored in the subscriber attribute storage section in the storage device of the switch, and when making a call, When a call is received, when a call is answered, or during a call, the control device of the exchange reads out the subscriber information, sends it to the terminal, and displays it on the display of the terminal.

However, for this purpose, the exchange must accumulate and maintain a large amount of subscriber information that differs from subscriber to subscriber, and in addition to being equipped with a large-capacity storage device, it is necessary to maintain and maintain the subscriber information.
The burden of maintenance and operation, such as preparing backup equipment in case of failure, has become significant, and in order to solve these problems, a method of distributing and storing subscriber information on terminals has become necessary. There is.

A means for inputting the subscriber information and dialing information when making a call, 4 is a communication control means, and the subscriber information stored in the subscriber information storage means 2 is transmitted to the exchange or the exchange. means for transmitting subscriber information to other terminals via the communication control means and receiving subscriber information sent from the exchange or other terminals; 5 is a display means for displaying subscriber information of other terminals received via the communication control means; and means for displaying the subscriber information stored in the subscriber information storage means; 6 is a control means, which controls each of the above means within the terminal 1 and also controls incoming and outgoing connections with the exchange; Means 7 is an exchange, which accommodates subscribers such as the terminal 1 and performs exchange connections.

[For production]

In FIG. 1, the user of the terminal inputs his own subscriber information, such as the user's name, which should be known to the other party in advance, using the input means 3 according to a predetermined procedure. The input subscriber information is accumulated and stored in the subscriber information storage means 2 under the control of the control means 6.

Further, the accumulated subscriber information can be displayed on the display means 5 via the control means 6 by inputting predetermined information from the input means 3, so that the contents can be confirmed.

In the above state, when terminal 1 makes a call, exchange 7 detects the call from terminal 1 and inquires of terminal 1 for subscriber information by a method not shown.

The inquiry is received via the communication control means 4 and transmitted to the control I means 6.

The control means 6 reads subscriber information corresponding to the contents of the inquiry from the subscriber information storage means 2 and sends it to the exchange 7 via the communication control means 4.

Thereafter, the connection is made by the exchange 7 according to the normal connection procedure, but when connecting to the other party's terminal (not shown),
The exchange 7 reads out the subscriber information of the other terminal, and sends the subscriber information of the other terminal to the terminal 1 along with information informing that the other terminal is being called or information indicating a response when the other terminal responds. Furthermore, at the time of a call, the exchange 7 sends the subscriber information of the terminal 1 to the other party's terminal and displays it on the display section of the other party's terminal.

The terminal 1 receives the subscriber information of the partner terminal sent from the exchange 7 at the communication control means 4 and sends it to the control means 6. The control means 6 sends the information to the display means 5, and displays the name of the other party, etc. together with the information indicating the calling or response to the user. Also, when there is an incoming call on terminal l,
Similar to the other party terminal described above, subscriber information of the other party terminal is sent from the exchange 7 at the time of connection, and the control means 6 which receives this information via the communication control means 4 causes the display means 5 to display the information.

In addition to the above, there are various display formats for subscriber information, and it is also possible to transmit and receive subscriber information between terminals and display it without using the exchange 7 as a relay.

Furthermore, if the exchange, subscriber lines, and terminals are digital, as in the case of L5DN (digital integrated service network), it is also possible to display the subscriber information of the other party's terminal during a call using a known method. .

〔Example〕

FIG. 2 is a block diagram of an embodiment of the present invention, and FIG. 3 is a sequence diagram of the embodiment of FIG.

In Figure 2, lla and llb are terminals, 12a and 12b are semiconductor memories, and 13a and 13b are input keys 1148 and 1.
4b is a communication control circuit, 15a and 15b are display devices, 1
6a and 16b are microprocessors, 21 is a switch,
22 is a central control unit, and 23a and 23b are subscriber circuits.

The explanation will be given below using both FIGS. 2 and 3.

In FIG. 2, the user of the terminal 11a previously inputs his or her subscriber information, such as name, etc., using the input key 13a.

The subscriber information is accumulated and stored in the semiconductor memory 12a under the control of the microprocessor 16a. The same applies to the terminal 11b.

In the above state, when the terminal 11a makes a call, the call information is transmitted to the terminal 11a by a well-known method as shown in (■) in FIG.
a is transmitted to the exchange 21. Exchange 21 is terminal 11
When a call from a is detected, an inquiry is made to the terminal 11a for subscriber information, for example, the name, as shown in (2) in FIG. The inquiry is received by communication control circuit 14a and communicated to microprocessor 16a. The microprocessor 16a reads the subscriber information corresponding to the content of the inquiry from the semiconductor memory 12a, and sends it to the exchange 21 via the communication control circuit 14a, as shown in (2) in FIG.

When the exchange 21 receives subscriber information from the terminal 11a,
A dial tone is sent to the terminal 11a as shown by ■ in FIG. When the terminal 11a inputs the dialed digits using the input key 13a, the dialed digits are sent to the exchange 21 as shown in FIG. When the exchange 21 connects to the other party terminal 11b, it makes an inquiry to the other party terminal 11b for subscriber information, as shown in (2) in FIG. In the other party's terminal 11b, the microprocessor 16b receives the inquiry via the communication control circuit 14b, reads out the subscriber information stored in the semiconductor memory 12b, and sends the inquiry to the exchange 21 via the communication control circuit 14b in accordance with FIG. Notify. When the exchange 21 receives the subscriber information of the terminal ub, it sends the subscriber information of the terminal 11a as calling party information along with an incoming call signal to notify the terminal 11b of the incoming call as shown in FIG. At the same time, the third
As shown in FIG. 2, information informing the terminal 11a that the terminal 11b is being called and the subscriber information of the terminal 11b are sent.

In each of the terminals 11a and llb, microprocessors 16a and 16b receive the above information via communication control circuits 14a and 14b, and display it on display devices 15a and 15b such as liquid crystal displays.

Further, the operation when the terminal 11a receives a call is the same as the operation of the terminal 11b described above.

Note that although the terminal 11a and the terminal 11b have been described above as being housed in the same exchange 21, even if they are housed in different exchanges, the same effect as described above can be achieved by exchanging information between the exchanges. Of course, it is possible to have

Furthermore, the subscriber information of the terminal 11a is sent to the terminal 11b at the same time as the incoming call signal to the terminal 11b, as shown in (■) in FIG. There are various ways to display subscriber information, such as transmitting subscriber information at the same time as the incoming call signal and displaying it on the display device 16b at the time of response. Furthermore, it is also possible to request the exchange to display the subscriber information of the other party's terminal during a call, or to display the subscriber information by directly exchanging it between the terminals 11a and 11b without going through the exchange 21. It is possible. Furthermore, the terminals mentioned above are not limited to voice terminals such as telephones, but may also be non-voice (data) terminals.

As is clear from the above, according to the present invention, there is no need to store subscriber information in the exchange 21, while the terminal 11a
, a memory is required on the llb side to store subscriber information. However, the amount of subscriber information accumulated in terminals is not large, and there is almost no need to specifically increase the storage capacity of the semiconductor memory that high-performance terminals with display functions normally have. Only the storage capacity for storing subscriber information on the side is reduced, and the effect is extremely large.

The present invention has been described above with reference to one embodiment, but even if various modifications can be made to the usage form of subscriber information as described above, the effects of the present invention will not change, and these are excluded from the present invention. It's not a thing.

[Effects of the Invention] As explained above, in the present invention, subscriber information is distributed and stored in terminals, so there is no need to store subscriber information in the exchange, and the capacity of the storage device for storing subscriber information is reduced. This greatly contributes to the economicalization of such a subscriber information storage system, since it is possible to significantly reduce the number of subscribers, and the trouble of maintaining and managing subscriber information on the exchange side is eliminated.
