Abstract: A method and apparatus of changing the number of calls in a multicall communication mode including detecting an occurrence of handover, transmitting a special message having inserted therein call-number changing information regarding the increase or decrease of a number of calls to a switching center as a connection destination connected by handover, transmitting the special message to inform a number of calls capable of being supported to a mobile terminal, receiving a reply regarding a desired call to be maintained selected from a plurality of calls, and rearranging the handover process so the desired call is maintained in connection while the call not desired is disconnected. Thereby allowing the user of the mobile terminal to select a desired call to be maintained when handover is executed under the congested state condition in the communication system which hinders smooth handover from one switching center to another.

Abstract: A communication service information providing method is comprised the step of storing both a plurality of communication services which are subscribed to by a subscriber and are made of plural sorts of information representation media, and identification information capable of selectively utilizing the communication services so as to establish a communication, and the step of notifying both the communication service subscribed to by a subscriber that wants to establish a communication, and the identification information corresponding to the communication service to a calling terminal in response to a request issued from the calling terminal. With employment of this structural step, it can acquire and/or confirm both the communication service subscribed to by the subscriber of the communication counter party and the identification information, or the identifier corresponding to this communication service.

Abstract: A method of storing subscriber data in a mobile-communication system includes the steps of providing a high-priority-subscriber-storage area in addition to an ordinary-subscriber-storage area, and storing subscriber data of a relevant subscriber in the high-priority-subscriber-storage area if priority of the relevant subscriber exceeds a predetermined threshold and if the ordinary-subscriber-storage area is full.

Abstract: The present invention mainly proposes a method of changing the number of calls in a multicall communication mode including a step of detecting an occurrence of handover, a step of transmitting a special message having inserted therein call-number changing information regarding the increases and decreases of number of calls to a switching center as a connection destination connected by handover, a step of transmitting the special message to inform a number of calls capable of being supported to a mobile terminal, a step of receiving a reply regarding a desired call to be maintained selected from the plurality of calls, and a step of rear ranging the handover process so that the call desired to be maintained is maintained in connection while the call not desired to be maintained selected from the plurality of calls by the first multicall mode supporting terminal is disconnected.
