Abstract (en)
[origin: WO0176313A1] In a remote unit (50) of a slotted mode wireless communication system, the handoff performance is improved. Search parameters for a preferred base station, and a desired number of neighboring base stations, are passed to a search engine during a preparation period (46) of an active state (42) of the remote unit prior to its assign slot. While in the preparation period (46), the search engine performs (70) searches and the controller evaluates the results. If one of the neighboring base stations' pilot signal is sufficiently stronger than the preferred base station (74) then a handoff is performed, assigning (76) the neighboring base station as the preferred base station. The handoff is completed before the remote unit enters its assigned slot (48).
