Abstract

PURPOSE:To reduce calling frequency by sending common report information to plural called terminals through a calling terminal as the user information and then extracting and storing the necessary information through each called terminal before decision of the possibility of communication. CONSTITUTION:A calling terminal 11 connected to an ISDN network 10 adds the user information UUI into a user-user information element transferred by the call control information on a D channel and sends the information UUI when a call is set. Then the information UUI is sent in a broadcast form to the called terminals 121-12n set on the same interface of a point-multipoint data link. The information UUI includes the identifiers to show the common report information on the time setting, for example, the information which are shared by the terminals 121-12n or the information on a specific terminal, etc. Each of terminals 121-12n extracts and stores the necessary information when receiving a call based on an identifier and before decision of the possibility of communication.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a user-to-user information communication system, and in particular, without checking contents by a network,
The user information in the user-user information element that is transparently transferred between the terminals is transmitted to the calling side ISD in a broadcast format.
The present invention relates to an inter-user information notification method that can be simultaneously set on a plurality of called ISDN terminals on the same path interface on N terminals.

[0002]

2. Description of the Related Art One of the basic functions provided by ISDN services in Japan is a user information notification service.

FIG. 7 shows the operation between conventional ISDN terminals. In the user information notification service, the calling IS
The DN terminal adds a maximum of 128 octets of information to the user information in the user-user information element transferred by the control information for call control of the D channel at the time of call setup, and the called side ISD.
Notify N terminals. Further, at the time of answering or disconnecting, the called ISDN terminal transfers a maximum of 1 to the user information in the user-user information element transferred by the control information for call control of the D channel.
Information of 28 octets can be added to notify the calling ISDN terminal. The ISDN network is a service that transfers the user information to the ISDN terminal on the other side without changing the user information.

In the conventional information notification system using the information notification service between users, when an ISDN terminal receives an incoming call,
First, the communication capability information element, the lower layer compatibility information element,
The higher layer compatibility information element, the called number information element, the called address information element, and the user-user information element are checked, and if the communicability is matched, the inter-user information is transferred to the partner terminal. On the other hand, if the communication possibilities do not match, the information that arrived is ignored.

[0005]

However, in the above-mentioned conventional method, as shown in FIG. 7, when an incoming ISDN terminal receives an incoming call, each information element is checked and the communicability is consistent. If not, the user information is ignored even if the user-user information element from the calling ISDN terminal is included. Therefore, by using the user information in the user / user information element transferred by the control information for call control of the D channel to the called ISDN terminals connected to the same path interface, the same information or time is used. When it is desired to transmit information, such as settings, to be set from the calling ISDN terminal at the same time, it is necessary to sequentially make calls from the calling ISDN terminal as many as the number of terminals, and there is a problem in that the required time is inefficient.

The present invention has been made in view of the above points, and a plurality of terminals are used instead of calling for the processing of notifying only the terminals having the same communication possibility as to the use of user information as in the prior art. It is an object of the present invention to provide an inter-user information notification method capable of setting the setting information from the calling ISDN terminal to the called ISDN terminal at one time.

[0009]

According to the present invention, when a plurality of callee ISDN terminals are connected on the same path interface of a point-multipoint data link at the time of an incoming call from the ISDN network, the called ISDN terminals are connected to each other before the communication possibility is judged. Use the information notification service of.

This is because the called ISDN terminal is the I side of the calling side.
Before responding to the user information from the SDN terminal, before determining whether communication is possible, the user information at the time of an incoming call is shared by a plurality of ISDN terminals on the called side or is used by each individual ISDN terminal. By identifying whether or not the user information is available and extracting and storing the user information at the same time when it is available, the setting information for a plurality of ISDN terminals on the calling side can be set at one time in the ISDN terminal on the calling side.
