A neighbor sector is automatically set to effectively perform soft handover. A base station corresponding to a first sector to communicate with a wireless terminal and a base station corresponding toa second sector to start communication with the wireless terminal due to movement of the wireless terminal or the like transmit a terminal identifier acquired from the wireless terminal, a time and asector identifier to a base station control part (control part in the following). The control part successively stores the received sector identifier into a table correspondingly to the terminal identifier and the time received from the base station. Besides, the control part refers to the table, judges whether different sector identifiers are stored in a previously determined time range, regardsa pair of the two different sector identifiers as neighbor sector candidates and counts the number of times they are regarded as the neighbor sector candidates. With respect to the neighbor sector candidates in which the counte
