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.
