Abstract
In a mobile radio system including at least one mobile station unit and a plurality of base station units, the mobile station unit communicates with a base station through time-division multiplexed control and communication channels. The mobile station unit includes a line quality detecting section for detecting the deterioration of the line quality occurring during communication, and a control section for controlling the entire unit. The control section includes a retrieval section which, when the deterioration of the line quality is detected by the line quality detecting section, interrupts current communication with a base station unit during a predetermined period, receives a control channel from another (new) base station unit during that period and then retrieves predetermined information, and a channel switching section which, when the predetermined information can be detected by the retrieval section, terminates the current communication with the base station and performs a process of connection to the new base station unit on the basis of the predetermined information.
