ABSTRACT:
A mobile station for communicating with a plurality of base stations, including: a field strength detecting circuit that detects a wave strength received from the base stations and outputs a received wave strength; and a base station switching control circuit that makes a comparison between the received wave strength and a first field strength threshold level, wherein, when the received wave strength is higher than the first field strength threshold level, data communication with one of the base stations which is in a connected state is performed, and when the received wave strength is lower than the first field strength threshold level, a search for base stations is performed.
