繰り返すことができるというものであった。There is a call waiting service in a general subscribed telephone as a method of interrupting between terminals already connected and talking. This is because, when one subscriber using the call waiting service is communicating with another subscriber, when a third subscriber makes a call to one subscriber, the third subscriber sends an interrupt tone to the one subscriber. When one subscriber hooks, the other subscriber is put on hold and a connection is established with the third subscriber, and when one subscriber hooks again, the third subscriber is put on hold. To reconnect with other subscribers and repeat this process.

た。However, when a person makes a direct call as in the above-mentioned call waiting service, the person who is the party determines the urgency and importance through the conversation and decides the partner to be given priority. Although it is possible to disconnect a connected call or to make a new call connection, especially when data terminals (DTEs) communicate with each other, the degree of urgency and importance are determined or given priority. There is a problem in that it is not possible to determine which party to call, and it is not possible to preferentially connect calls with high urgency or importance.

うことを特徴とする。According to the present invention, in order to solve the above-mentioned problems, a call connection between terminals subscribed to ISDN, which exchange messages via a control channel and communicate via an information channel. In the method, when a call connection between one terminal and another terminal is made, a call setup message including information indicating a call priority is transmitted from the calling terminal to the called terminal, and when the call connection is completed, one terminal and the other terminal are transmitted. A call setup message containing information indicating the priority of a call from a third terminal to one of the connected terminals or the other terminal in which information indicating the priority of the call is stored in both the terminal and the terminal. Is transmitted, the one terminal or the other terminal that has received the call setup message compares the stored call priority with the call priority in the call setup message from the third terminal. Of the stored call If the priority is high or if the priority of the stored call is equal to the priority of the call in the call setup message, the connected call is continued, a disconnection message is returned to the third terminal, and the call setup message is returned. If the priority of the middle call is high, a disconnection message is transmitted to the connected terminal to disconnect the call forcibly, and information indicating the priority of the new call with the third terminal is transmitted. A similar call connection including storage is performed.

In this case, by comparing the priority included in the message with the stored priority, it is possible to determine which call has a higher priority. Calls with a high degree of importance and importance can be connected preferentially.
