Abstract
An apparatus and method for providing multimedia broadcast and multicast services in a CDMA (Code Division Multiple Access) mobile communication system. The apparatus and method enable a common MBMC (Multimedia Broadcast/Multicast Control) layer to be allocated between a plurality of cells, enable MBMC layers to be classified on the basis of types of services, and use the classified MBMC layers. That is, individual MBMC layers do not have to store large-capacity data because a unique service or transmission rate in each of cells is based on a slow rate, and the individual MBMC layers corresponding to respective cells process a service requiring complex scheduling. Moreover, the apparatus and method enable the same information to be provided to a plurality of cells and enable a streaming-type service to be processed in a common MBMC layer commonly used in the cells. The apparatus and method can not only reduce an overhead of storage and processing devices but also minimize a time difference between broadcast and multicast timings of different cells, by enabling the common MBMC layer to commonly process MBMS information for the plurality of cells.
