发明名称 LOCATING A REMOTE UNIT
摘要 A base station (101) calculates a location of a remote unit (113) using a first location technique. The first location technique is a single-site estimation of a PN offset for the remote unit (PN>primary< >site<). PN>primary< >site< is then forwarded by the base station (101), along with its base station identification, to locating equipment (107). Equipment (107) then passes a second location request to the serving base station (101) and those base stations neighboring the serving base station (neighbor base stations). PN>primary< >site< is sent with the second location request, along with an identity of the base station that made the first location estimate. The neighboring base stations then calculate a "search window" for each base station to search when locating the remote unit (113). The search range is based on the first location, and the identity of the base station that made the first location estimate.
