Abstract
In the method of handover control, when a mobile station recognizes that the mobile station has moved to an overlapping area, the mobile station notifies this fact to a network side and in response the network side sets up only a communication channel between a handover target base station and an exchange station for controlling that handover target base station, without setting up a radio channel between the handover target base station and the mobile station, while continuing the communication by not releasing the communication channel between the currently located base station and the exchange station and the radio channel between the currently located base station and the mobile station, so that it becomes possible to reduce a transmission control load for transmission between the base station and the exchange station as well as a control load for controlling the exchange station itself.
