Title: Mobile communication system for predicting a transfer location of a mobile station

Abstract: A mobile communication system which performs a handover operation with high-reliability, while the system can flexibly cope with various circumstances in which a mobile station is used, without changing a hardware structure. A plurality of radio base stations form respective radio communication cells. Each of the radio base stations performs a radio channel setting control including a handover with respect to a call originated for the mobile station located in one of the cells. An exchange is connected to each of the radio base stations via a communication link so that the exchange performs a call process of the call in association with the radio channel setting control performed by the radio base stations. After the call becomes a completed call and prior to a handover operation, a movement of the mobile station from one of the cells in which the mobile station is located to another one of the cells adjacent to the one of the cells is predicted based on at least one of procedures of the radio channel setting control and the call process. When the movement is predicted so as to select candidate cells which are candidates of a transferee of the completed call, a free radio channel of the cells is acquired. A path connected to the acquired free radio channel is formed in the communication link.
