ABSTRACT:
In a base station providing a large-distance service area (large area) such as a mobile communication system WLL of the CDMA method, the time required for performing call search (path search) is reduced so as to reduce the call connection time. When performing a path search in the base station (8), a predetermined offset value from a reference time is set so that path search is performed only in a doughnut-shaped service area (30). Thus, there is no need of performing path search in the vicinity of the base station (8) and search is performed only in the doughnut-shaped service area (30). Thus, it is possible to reduce the path search time and reduce the call connection time.
