METHOD FOR PERFORMING CELL SELECTION IN A MOBILE COMMUNICATION SYSTEM AND SYSTEM THEREFOR

摘要

A method for performing cell selection in a mobile communication system and a system therefor. Upon receiving a Multimedia Broadcast and Multicast Service (MBMS) service or a unicast service, a User Equipment (UE) performs cell search separately for each frequency band in an overlapping region between an MBMS-dedicated frequency band and a unicast service-available frequency band. In a first example, the UE allocates different cell identification codes for each cell according to types of the corresponding frequency bands to perform cell search. In a second example, the UE uses the system information broadcasted from the network over P-BCH to indicate whether each cell belongs to the MBMS-dedicated frequency band.
