Patent ID: 7403799

Claim:
A base station for performing a search for a call from a terminal in a service area having a predefined size, said base station comprising: a search section, said search section including: a data section for inputting first and second distance data of the service area; and a path search section for determining a timing of a path search on the basis of a chip offset, said chip offset being a predetermined offset value based on a base time to perform the search in an area less than said service area and between said first and second distances, wherein the search section determines a time delayed from the base time by the predetermined offset value as a search start time, wherein the search section performs the search during the period from the search start time to a predetermined search finish time, and wherein the search section further includes a chip converting section for converting, in response to inputs of parameters that are to serve as the offset value and the search finish time, the parameters into the offset value and the search finish time.
