Patent ID: 6892072

Claim:
A method of optimizing a search for cells in a mobile telecommunication network comprising a plurality of cells, each cell accommodating a base station exchanging synchronization data with a mobile device UE via a SCH channel so as to allow subscribers' mobile devices to perform measurements on at least one cell adjacent to a current cell for retrieving a scrambling code specific to said adjacent cell, said synchronization data comprising an integral number of frames, each frame comprising an integral number of slots, and said channel SCH being subdivided into a primary synchronization channel that comprises a primary code C p used for detecting a beginning of a slot, and a secondary channel that comprises a secondary code C s i,k containing N s chips used for detecting a beginning of a frame, the method comprising: applying a digital filtering to measurement samples collected in a plurality of time windows so as to give a major weight to the measurements performed in most recent time windows.
