ABSTRACT:
A method of optimizing the search for cells in a mobile telecommunication network comprising a plurality of cells, each cell accommodating one base station exchanging synchronization data with a mobile device UE via a channel SCH, so as to allow subscribers' mobile devices to perform measurements on at least one cell adjacent to the current cell for retrieving a scrambling code specific to the adjacent cell. The method has a step of applying a digital filtering to measurement samples collected in a plurality of time windows so as to give a major weight to measurements performed in the most recent time windows.
