Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to an incoming call display method for a terminal connected to an integrated digital communication network (so-called ISDN network), and in particular to an ISDN
This invention relates to a method for displaying the caller's name on the terminal based on caller information sent from the network.

(Background and Problems of the Invention) For example, the inventor previously applied for a patent application in 1987-87 as an effective call display system that can prevent prank calls, threatening calls, etc.
No. 773 (Japanese Unexamined Patent Publication No. 62-243452) proposed an incoming call display method (hereinafter referred to as the prior invention) that can display the caller's name on the terminal.

In this prior invention, a terminal is provided with a memory that registers the correspondence between a telephone number and its subscriber name, and when a call is received, the caller number sent from the ISDN network is converted into a caller name by referring to the memory and displayed. The display of the caller's name is limited to the subscriber registered on each terminal.
Providing a memory for converting a caller number to a caller name and its control circuit in each terminal increases the cost of the terminal as the number of caller names displayed increases. The prior invention is effective for terminals such as home telephones, which require a relatively small number of caller name displays, due to the complexity of inputting data corresponding to caller names. This method is not sufficient as a caller name display method for a terminal such as a telephone that receives calls from a relatively large number of subscribers.

In view of the above, it is an object of the present invention to construct a communication network in which almost all caller names can be displayed on a receiving terminal.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides an identification device for identifying a caller name from a caller terminal in a switching center of an ISDN network, and transmits caller information to a receiving station. The caller's name can be displayed on the receiving terminal, or a translation device from subscriber number to subscriber name can be connected to the ISDN network while the caller's number information is being sent from the calling station to the receiving station. In the process, the caller number information was translated into a caller's name, so that the caller information arrived at the receiving station as the caller's name, or data corresponding to the subscriber number and subscriber name was stored.

A database is provided, and when an incoming call is received, the incoming terminal accesses the database and transfers the caller number information sent from the I5I)N network to the incoming terminal to the database. The subscriber name information corresponding to the received caller number information is sent back to the receiving terminal, and the caller's name is displayed on the receiving terminal.

(Operation) The conversion means from caller number to caller name (caller name identification device, translation device, database) covers all subscribers, excluding some terminals such as special telephones. , almost all callers can be displayed by name on the receiving terminal. In addition, the conversion means is shared by many subscribers, so that it is possible to provide a caller name display service at a low overall cost.

(Embodiment) FIGS. 1, 2, and 3 show the first and second embodiments of the present invention, respectively.
It is a construction diagram of a communication network explaining the second and third embodiments.

To explain the first embodiment, as shown in FIG.
Each switching center 2.3 of the DN network 1 has a respective switching center 2.3.
An identification device 4.5 is provided for identifying the subscriber name from the accommodation terminals of all the subscribers accommodated in the subscriber station 3. This identification device 4
．． 5 has a table storing comparison data of subscriber terminals and subscriber names for all subscribers accommodated in each exchange 2.3.

Assuming that the subscriber who owns terminal A is the calling party and the subscriber who owns terminal B is the called party, exchange 2 is the originating station and exchange 3 is the terminating station.

When a call is made from terminal A, the calling station 2 identifies the subscriber name (caller name) of the caller terminal a from the subscriber terminal-subscriber name comparison table of the identification device 4. When a communication path is established between the originating station 2 and the terminating station 3, the originating station 2 sends the caller name information obtained through the above identification operation to the terminating station 3. The receiving station 3 sends a paging signal to the terminal B, and also transfers the caller name information to the receiving terminal B, and in response to this, the caller's name is displayed on the display section of the receiving terminal B. In addition, in the above operation, the operation of identifying the caller's name at the originating station 2 is performed by the originating station 2 and the terminating station 3.
This may be done after a communication path has been established between the two parties.

Next, explaining the second embodiment, as shown in FIG.
Connected to a relay station 6 included in the ISDN network 1 is a translation device that translates a subscriber number into a subscriber name. This translation device has a table storing translation data from subscriber numbers to subscriber names for all subscribers of the ISDN network 1. Further, the station to which the translation device 7 is connected may be a station at any level including the subscriber accommodation station (switching station 2.3) and the relay station 6, taking into account the construction area of the ISDN network 1. A translation device is provided in one or more stations (in the embodiment, a translation device is provided in relay station 6). ).

As in the first embodiment, the operation will be described assuming that terminal A is the originating terminal and terminal B is the receiving terminal.

When a call is made by terminal A and a communication path is set up between the calling station 2 and the receiving station 3 via the relay station 6, the sending station 2 calls the calling terminal A as determined from the accommodation terminal a of the calling terminal A. The subscriber number information is sent. This subscriber number information is relay station 6
The information is received by the relay station 6, translated into subscriber information (caller name information) by the translation device, and then sent from the relay station 6 to the destination station 3. The receiving station 3 sends a paging signal to the receiving terminal B, and also transfers the caller name information sent from the relay station 6 to the receiving terminal B. Upon receiving this, the display of the receiving terminal B displays the caller's name information. The name will be displayed.

In the above operation, if there is no exchange or relay station (hereinafter referred to as translation station) connected to the translation device 7 on the communication path set between the calling terminal A and the receiving terminal B, The nearest translation station is called from the switching station or relay station on the communication path, and the caller's name information is sent from the translation station to the destination station 3.

Next, explaining the third embodiment, as shown in Fig. 3,
A database 9 that stores correspondence data between subscriber numbers and subscriber names is connected to the switching center 8 of the ISDN network 1 (the switching center 8 is hereinafter referred to as a database subscriber station). The above correspondence data for all subscribers of is stored. Also, the database 9
itself is also a subscriber of the ISDN network 1.

As in the first embodiment, the operation will be described assuming that terminal A is the originating terminal and terminal B is the receiving terminal.

When a call is made by terminal A and a communication path is established between the originating station 2 and the terminating station 3, the originating station 2 sends a message to the terminating station 3 from the originating terminal A determined from the receiving terminal a of the originating terminal A. The subscriber number information is sent. The receiving station 3 sends the subscriber number information to the receiving terminal B together with the paging signal.0 The receiving terminal B accesses the database 9 upon receiving the paging signal. That is, the telephone number in the database 9 is automatically sent from the receiving terminal B, and a communication path is thereby established between the database subscriber station 8 and the receiving station 3. Thereafter, the receiving terminal B sends the subscriber number information sent from the receiving station 3 to the database 9.
receives the subscriber number information, translates it into subscriber name information (caller name information), and sends it to the receiving terminal B via the database subscriber station 8 and the receiving station 3. In response to this, the caller's name is displayed on the display section of receiving terminal B.

In the first to third embodiments described above, subscriber number information or caller name information can be transmitted using either the circuit switched network of the ISDN network 1 or the common line signaling network.

(Effects of the Invention) As explained above, the present invention provides a means for converting a caller number to a caller name in the ISDN network itself or in a specific subscriber (database) connected to the ISDN network. In addition to displaying the caller's name from all subscribers of the ISDN network on the receiving terminal, the above conversion means is shared by all subscribers of the ISDN network, so the caller's name can be displayed at low cost from the perspective of the network. There are advantages that this display service can provide.
