Multicasting is an efficient way for delivering rich
multimedia applications to large user groups as it allows the
transmission of packets to multiple destinations using fewer
network resources. Content and service providers are
increasingly interested in supporting multicast
communications over wireless networks and in particular over
Universal Mobile Telecommunications System (UMTS). To
this direction, the third Generation Partnership Project (3GPP)
is currently standardizing the Multimedia Broadcast/Multicast
Service (MBMS) framework of UMTS. In this paper, we
present an overview of the MBMS multicast mode of UMTS.
We analytically present the multicast mode of the MBMS and
analyze its performance in terms of packet delivery cost under
various network topologies, cell environments and multicast
users? distributions. Furthermore, for the evaluation of the
scheme, we consider different transport channels for the
transmission of the data over the UTRAN interfaces and
propose a cost based scheme for the efficient radio bearer
selection that minimizes the packet delivery cost.
