Abstract
A method and apparatus for improving search efficiency in a remote unit of a slotted mode, wireless communication system. In a slotted mode communication system the remote unit is in an “active state” only during its assigned slot. A controller in the remote unit passes a selected set of search parameters to a search engine at the beginning of the assigned slot. The search engine performs a search, using the selected set of search parameters, and stores the search results. The controller then immediately passes another set of search parameters to the search engine for the next search without evaluating the results of the just completed search. Searching continues as long as the remote unit is in its assigned slot. When the remote unit enters the inactive state the controller evaluates the results of the searches performed during the active state. Evaluation of the search results provides a basis for the controller to generate new sets of search parameters to be used during the next active state of the remote unit.
