摘要
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.
