ABSTRACT:
A method and apparatus for improving searching in a remote unit of a slotted mode, wireless, communication system. In a slotted mode communication system, the remote unit enters an “active state” during its assigned slot. While in the active state, a controller in the remote unit passes selected sets of search parameters to a search engine. The order that the searches are performed is based on the measured signal strength and the age of the measurement. The search engine performs searches using the selected sets of search parameters. Searching continues as long as the remote unit is in the active state. When the remote unit enters the inactive state, searching ceases. While in the inactive state, the controller evaluates the results of the searches performed during the previous active state. During the next active state, the next sequence of searching is performed based on measured signal strength and the measurement age corresponding to the measurements made during the previous active state.
