摘要：PURPOSE:To prevent interruption of communication caused by zone change by using a receiver of a mobile station having two receivers not in communication with a zone mobile station and a base station, receiving a radio wave of the base station at a zone being a moving destination and discriminating to which of base stations is closer to the area. CONSTITUTION:A mobile station has two receivers 17, 18 having a diversity function and the receiver 17 uses an antenna 19 to send/receive communication information with a base station 2 through a space path 5. The mobile station 1 uses the receiver 18 not in use at present and makes communication with the base station 3 with an antenna 20 and a space path 6, and the receiver 18 receives a protocol from the base station 3. Thus, the mobile station 1 uses the diversity receiver 18 to change a zone without interrupting communication of a protocol with the base stations 2, 3. Thus, communication interruption attended with zone changeover is prevented and the continuity of talking with a public network is kept.
