Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to, for example, a communication system compatible with I5DN that is expected to be constructed in the future.

(Prior Art) In recent years, studies have been underway to digitize various communication networks and integrate them into one network from an international perspective, led by the CCITT (Consultative Committee for International Telegraph and Telephone). 15DN (Integrated Service Digital Network) is a specific example of this, and attempts to realize and provide unprecedented services by integrating networks related to voice, insurance, and data.

At CCITT, this ISDN-related recommendation is called the Summer Series, and its recommendations are 1,430.1.441.
1.451 stipulates the basic interface. According to the regulations regarding this basic interface, when making a call, for example, information called a "calling number" corresponding to the "telephone number" of the calling terminal can be sent to the receiving terminal.

Figure 4 shows the format of the message "call setup" specified in 1.451, which corresponds to layer 3 in the 08l (open system interconnection) model defined by l08 (International Organization for Standardization). A message is sent to a receiving terminal when making a call.

Information called "protocol identifier" is inserted into the first octet of the message shown in the figure.

This "protocol identifier" is information indicating what kind of protocol is adopted as layer 3 by the receiving terminal. Information called "message type" is inserted into the third octet. In this "message type", information for identifying the type of message used in layer 3 is inserted. If the message is a call setting message, it is specified that it is coded as "00000101".

After this message type, some pieces of information are inserted, and then the above-mentioned "calling number" and "calling subaddress" information for notifying sender information are inserted. As mentioned above, this “calling number” is the “calling number” of the calling terminal.
"telephone number", i.e. corresponds to the subscriber number.Also,
The "calling subaddress" corresponds to the extension number of the calling terminal.

Following these pieces of information, information called "address number," which is the subscriber number of the receiving terminal, and information called "blue subaddress," which is its extension number, are inserted.

Then, the "terminating number" and "terminating subaddress" are inserted by the originating terminal and sent to the exchange, where they are used as information for switching connection. Since this information is unnecessary for the receiving terminal, it is normally removed by the exchange. on the other hand,
The "calling number" and "calling subaddress" may be inserted at the calling terminal or at the exchange. This information is delivered to the communication terminal and displayed on, for example, a display. This provides a service in which the user on the called side knows the origin of the call.

By the way, with such a service, although it is possible to identify the originating terminal itself, it is not possible to identify the user who is using the originating terminal.

For example, in telephone communications within a company's internal communication network, information such as organization name, job title, and person's name cannot be rejected from incoming calls.
The method of reception may cause problems or cause the reporter to feel uneasy.

(Problem to be Solved by the Invention) In the communication system described above, when receiving a call, the user can identify the originating terminal itself, but cannot identify the user using the originating terminal. There is a problem.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a communication system that allows a user to identify the user who is using the terminal that is the originator when receiving a call.

[Structure of the Invention] (Means for Solving the Problems) The present invention is a system in which, when making a call, a calling terminal can send a message containing identification information for identifying the calling terminal to a receiving terminal, This identification information shall consist of a plurality of pieces. Then, the identification information is selected from these pieces of identification information and included in the message according to predetermined conditions regarding the receiving terminal.

(Function) In this invention, when a call is received, identification information according to predetermined conditions regarding the called terminal is sent to the called party, so that the user on the called party can identify the user, etc. who is using the calling terminal. Can be identified.

(Example) The present invention will be described in detail below.

FIG. 1 is a system configuration diagram according to an embodiment of the present invention, and assumes, for example, a part of an in-house communication network system.

In the figure, 1 is a private branch exchange, and 2 is a line connected to another private branch exchange or a public network.

3 is a group of communication terminals connected to the private branch exchange 1;
A I, A2... are telephone terminals, B1... is FA
X terminal, C1, . . . indicate data terminals.

Furthermore, this communication system is compatible with l5DN. Therefore, the interface connection point S between exchange 1 and terminal 3, that is, 11.122-CCI T shown in the drawing
T Recommendation 1 Series, I, 430°1.441.1.
It satisfies the basic interface specified by 451 etc. Furthermore, when making a call to the 15DN network, the call is made based on the regulations stipulated in 1.451.

Therefore, the message "call setup" shown in FIG. 4 will be sent to the 15DN network. Then, the subscriber number of the calling terminal is inserted into the ``calling number'' of this ``call setup'' message, and the extension number of the calling terminal is inserted into the ``calling subaddress''. On the other hand, in the communication system of this embodiment, when a call is made to a network other than the 15DN network, for example, when a call is made to a terminal connected to an in-house communication network, a "call setup" message is sent as described above. However, information such as the caller's name, organization name, job title, etc. is inserted in the area where the "calling number" or "calling subaddress" should be inserted. When receiving a call on an l5DN compatible terminal, "Call settings"
A service is provided that displays the subscriber number and extension number of the calling terminal from the "calling number" and "calling subaddress" inserted in the message. Therefore, the caller's name, organization name, job title, etc. are displayed on the terminal receiving the call.

The user of this terminal can know the other party from such a display before starting a conversation, and can devise the status of previous contact with the other party, how to respond, etc. In addition,
In this embodiment, as mentioned above, when making a call to the 15DN network, standardized regulations are followed, so the CCI
It does not undermine the TT recommendations.

The second embodiment will be explained in more detail.

FIG. 2 shows the external appearance of the telephone terminal A1 shown in FIG. 1, and FIG. 3 shows the functional configuration.

As shown in FIG. 2, this telephone terminal A1... has a numeric keypad, a "#" key, and a "*" key, as well as function keys FN1 to FN4 having special functions. It also has a display section for performing various displays.

In addition, as shown in FIG.
4, a key human power analysis section 5 that analyzes key human data, and a call source in which the subscriber number, extension number, caller name, organization name, job title, etc. of the own terminal are registered. It has a transmission data creation section 7 that creates transmission data from various messages according to the format shown in FIG. 4, and a transmission control section 8 that controls the protocol with the other party's terminal.

When making a call, take the handset (not shown) off-hook as if making a normal phone call, enter the other party's phone number using the keypad 4, or the numeric keypad or the "#" key.
Manually use the “*” key. The key-manufactured data is sent to the key-manpower analysis section 5 and analyzed. As a result of this analysis, if the destination is a terminal connected to the 15DN network, the subscriber number and extension number of the own terminal are indexed from the source identification information table 6, and the code is passed to the transmission data creation section 7. In addition, if the destination is not a terminal connected to the 15DN network but a terminal connected to an in-house communication network, the sender's name, organization name, job title, etc. as described above are stored in the sender identification information table. The code is similarly indexed from 6 and passed to the transmission data creation section 7. Transmission data is then created by the transmission data creation section 7 based on such a code, and sent to the recipient side via the transmission control section 8.

Furthermore, in this embodiment, when specifying the other party's terminal connected to the intra-company communication network, the sender's name, organization name, or job title can be arbitrarily selected.

First, the operation up to the manual input of the other party's telephone number is similar to the above-mentioned operation, but after this, for example, the function key FNI is input manually, followed by a number using the numeric keypad. In this embodiment, the function key FNI indicates the caller's selection key, and the correspondence between the user and the numbers is determined in advance. Therefore, the key human power analysis unit 5 can identify the caller's name using the function key FNI and the number following it, and can also search for the code from the caller identification information table 6. Similarly, FN2 is the organization name, FN3
If is used as a function key to select a job title, various organization names and job titles can be specified in combination with numbers. Then, similar to the operations described above, transmission data is created based on these codes and sent to the recipient side.

Here, regarding the code of the source identification information table 6, it has been decided to use IA5 in CCITT Recommendation 1,451, so it is used when connecting to the SDN network. On the other hand, when connecting to an in-house communication network, by using a table that even includes kanji codes, it is possible to display kanji characters as shown in display section D in FIG. 2. The technique of displaying kanji from kanji codes in this manner is a well-known technique and can be fully realized by using a ROM that stores kanji patterns, so the explanation thereof will be omitted here. Furthermore, although the example of displaying kanji has been described here, it is also possible to use hiragana, katakana, special symbols, figures, etc.

In addition, as for the method of pre-registering the sender's name, organization name, job title, etc. in the sender identification information table 6, there is a method of creating a ROM in a separate device, or a method using the keypad and function keys shown in Fig. 2. One possible method is to input the code.

As described above, this embodiment satisfies the standard method when connecting to the 15DN network, but when connecting to the in-house communication network, the sender's name, organization name, etc., which are more effective information,
Detailed information such as job title is transferred to the receiving terminal and displayed, which eliminates the anxiety of not knowing where the call is coming from.Also, by knowing the person who is calling, you can plan how to respond in advance. This can be expected to have the effect of being considerate.

In this embodiment, the originating party identification information is controlled by the originating terminal, but this may also be done by, for example, a private branch exchange.

[Effects of the Invention] As described above, the present invention has the effect that when receiving a call, the user can identify the user who is using the terminal that is the originator.
