Abstract
While a plurality of cellular mobile communication systems have their respective service areas regionally overlapping each other in part, a mobile station is configured to perform a standby for calling or communication while selecting one of the plural systems in the overlapping areas, and is arranged as follows: the mobile station preliminarily stores cell information notified of by a base station and indicating whether the mobile station is transferable to each surrounding cell while maintaining the current system; when the arrival of transfer timing to a surrounding cell is detected, the mobile station extracts the information about the pertinent cell and judges whether the surrounding cell is a transferable cell, based on the cell information; when the surrounding cell is a transferable cell, the mobile station transfers to the surrounding cell; when the surrounding cell is not a transferable cell, the mobile station directly transfers to a cell of a different system. This makes it feasible to decrease communication down time and decrease power consumption of the mobile station.
