PURPOSE:To realize an exchange system for a mobile communication whose affinity with a conventional wire system interface can be improved, and whose constitution is simple by sufficiently preventing a hit when a cordless terminal is moved across radio base stations. CONSTITUTION:A cordless switch 20 is interposed between a base station interface part 71 which operates an interface between a radio base station 50 and a switchboard main body, and transformer coders 72 and 73 which exchange encoded data on a radio line with the encoded data in the switchboard. The cordless switch 20 is the device for tracing a movement whose path is switched by a cordless controller when a cordless terminal 60 is moved across the radio base stations. |
