METHOD FOR RETRIEVING CHANNELIZING CODE BY USING PILOT PATTERNS, CAPABLE OF QUICKLY PERCEIVING OPERATED STATE OF BASE STATION THROUGH ONLY THE REALIZATION OF PHYSICAL LAYER WITHOUT ADDITIONAL CALL PROCESSING

摘要

PURPOSE: A method for retrieving a channelizing code by using pilot patterns is provided to self-retrieve a channelizing code by using pilot bit patterns of a channel transmitted by a base station, thereby quickly perceiving an operated state of the base station through only the realization of a physical layer without an additional call processing. CONSTITUTION: A system selects an OVSF(Orthogonal Variable Spreading Factor) code for performing a despreading process according to a predetermined OVSF code selection rule(S601), and carries out the despreading process for a signal transmitted from a base station by using the selected OVSF code(S602). The system compares pilot bit patterns of symbols obtained through the despreading with pilot bit patterns prestored on a table(S603). If identical pilot bit patterns exist(S604), the system decides the selected OVSF code as being assigned by the substantial base station(S605).
