Abstract

PURPOSE:To obtain the ISDN terminal device which is connected to an ISDN network, specie, a terminal device which can accurately display information regarding an originator of originator number report or subaddress report service, etc., at the time of termination. CONSTITUTION:The origination number and origination subaddress of an originator side are sent to an opposite terminal side, where originator information corresponding to previously registered origination number information and origination subaddress information on the originator is retrieved in a storage control part 3 based on the sent origination number and origination subaddress and displayed at a display control part 5, so that the accurate retrieval result from the storage control part 3 can be displayed even when a different originator corresponds to termination from the same contractor number, for example, when the origination number information is the same and the originator is different.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ISDN terminal device connected to an ISDN network, and more particularly to a terminal device capable of displaying information about a caller such as a caller's number notification or sub-address notification service when an incoming call arrives.

[0002]

2. Description of the Related Art As a conventional ISDN terminal device, a technique has been proposed in Japanese Patent Laid-Open No. 3-175860, which displays a subscriber's information based on the telephone number of the caller and the telephone number when receiving a call.

[0003]

However, in the prior art, when the incoming call arrives, the ISD is changed according to the telephone number of the caller.
Since the caller information corresponding to the caller's telephone number output by the N communication processing unit is retrieved from the storage unit and displayed on the display unit, even if the caller is different for an incoming call from the same contractor number (When the calling number information is the same but the caller is different) There is a problem that the results retrieved from the storage unit are displayed.

In most cases, only one contractor number can be assigned to an ISDN line (except for dial-in numbers). Therefore, the calling number information alone is insufficient as a means for searching the sender information. This is a problem that arises.

[0005]

The present invention is to solve these problems, and stores a telephone number, a plurality of subaddresses corresponding to the telephone number, and caller information corresponding to each subaddress. Storage unit, an ISDN communication processing unit for outputting the telephone number and subaddress of the caller when receiving a call, and a display unit, and the telephone number and subaddress of the caller output by the ISDN communication processing unit when receiving a call There is provided an ISDN terminal device having control means for displaying the corresponding caller information on the display unit after the corresponding caller information is retrieved from the storage unit.

[0006]

According to the ISDN terminal device configured as described above, the calling party number and calling party subaddress of the sender are transmitted to the partner terminal side, and the partner terminal side is based on the transmitted calling party number and calling party subaddress. Then, the caller information corresponding to the caller's calling number information and calling subaddress information registered in advance is retrieved from the storage control unit and displayed on the display control unit, so that an incoming call from the same contractor number can be received. On the other hand, even when the caller is different (when the calling number information is the same and the caller is different), the accurate search result from the storage control unit can be displayed.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram for explaining an ISDN call control unit of the present invention, FIG. 2 is a schematic diagram of a configuration of an embodiment of the present invention, and FIG.
FIG. 3 is a schematic diagram showing an example of a display on the display unit shown in FIG. 2 of the present invention. In the figure, the same parts are designated by the same reference numerals. In the figure, (1) is calling number information, (2) is calling subaddress information, (3) is a storage control unit, (4) is an ISDN call control unit,
(5) is a display control unit, (6) is a data search unit, (7) is a central control unit (CPU), and (8) is a bus.

Next, the operation in such a configuration will be described. FIG. 1 shows an explanation of an ISDN call control unit according to the present invention. Calling party number information (1) and calling party subaddress information (2).
Are coded or formatted as shown.

FIG. 2 shows an embodiment of the present invention, in which a plurality of calling number information (1), calling subaddress information (2), and a storage control unit (3) for preliminarily storing caller information relating to each of them, Interfacing with ISDN line,
An ISDN call control unit (4) that outputs calling number information (1) and calling subaddress information (2) of the caller when a call arrives; a display control unit (5) that displays information about the calling number and the caller;
A data search unit (6) for outputting the address number of the storage control unit (3) from the calling number information (1) of the caller and the calling subaddress information (2) output by the ISDN call control unit (4) at the time of incoming call; A central control unit (CPU) (7) for controlling the entire ISDN terminal device of this embodiment via a bus is provided.

FIG. 3 is a diagram showing an example of a display on the display unit shown in FIG. 2 of the present invention.

Next, the operation of the present embodiment when receiving an incoming call will be described with reference to FIGS. 1 to 3. The storage control unit (3) has a plurality of calling number information (1) and calling subaddress information (2).
Information regarding the sender, such as the company name, the face (image information) of the sender, the affiliation, and the name, is pre-registered.

The ISDN call control unit (4) detects the calling party number information (1) and the calling party subaddress information (2) among the incoming call information that arrives via the ISDN line, and the calling party number information (1) and the calling party subaddress. The information (2) is notified to the central control unit (CPU) (7) via the bus (8). Central control unit (CP
U) (7) searches the address number of the storage control unit (3) by the data search unit (6) from the notified calling number information (1) and calling sub address information (2), and the storage control unit by this address number. Information about the sender for the calling number information (1) and the calling subaddress information (2) is read from (3), and the display control unit (5) displays the company name of the sender and the sender's name as shown in FIG. 3, for example. Information such as face (image information), affiliation, and name is displayed.

[0013]

As described above, according to the configuration of the present invention, the IS information in the incoming call information coming through the ISDN line is used.
The DN call control unit detects the calling number information and the calling sub address information, and notifies the central control unit of the calling number information and the calling sub address information via the bus. The central control unit searches the address number of the storage control unit by the data search unit from the notified calling number information and the calling subaddress information, and the storage control unit uses this address number to obtain the information about the sender for the calling number information and the calling subaddress information. Since it is read out, even if the caller is different for the incoming call from the same contractor number (when the calling number information is the same and the caller is different), the accurate search result can be displayed from the storage control unit, so that the caller can be displayed. Incorrect display of information will be eliminated. Further, the calling side can accurately notify the called side by the sub address even if the calling side does not have any number of telephone numbers (contract number). Further, if the user / user information is also used as the information at the time of the incoming call in the search means, the sender information at the time of the incoming call can be notified in more detail.
