Abstract :
SIP-based multi-party conference service (MFCS) of IETF is adopted by 3GPP2 as conferencing solution. In MFCS, the service content received by multiple participants is the same. So, it is better to use multicast to support MFCS in 3G network, where air resources are limited. In 3GPP2, broadcast multicast service (BCMCS) is standardized allowing optimization of air resources for delivery of uniform content to multiple access terminals in CDMA2000 communication system. In this paper, a new solution is proposed, wherein service mapping is set up between BCMCS and MPCS in CDMA2000 network. By utilizing BCMCS, the radio and access network´s resources of the CDMA systems could be saved for MPCS.
