ABSTRACT:
A method and apparatus for determining soft handover in a CDMA mobile communication system supporting Multimedia Broadcast/Multicast Service (MBMS) is provided. In the asynchronous CDMA mobile communication system supporting MBMS, when a UE moves to a region where it can receive data from a plurality of Node Bs, the UE determines whether to perform soft combining using a measurement value of a dedicated pilot channel signal, in performing soft handover. In this way, the UE can determine whether to perform soft combining on MBMS data received from a plurality of Node Bs by itself. Therefore, even though an MBMS user moves from a current or existing cell to a new cell, a stable MBMS service is provided to the user, thereby contributing to the user's convenience.
