METHOD FOR ENABLING MULTICAST TRAFFIC FLOWS OVER HYBRID MULTICAST CAPABLE AND NON-MULTICAST CAPABLE RADIO ACCESS NETWORKS (RANS)

摘要

A method for multicast packet communication by mobile entities (113) using oneor more radio access networks(RANs) (107, 109, 111) that include receiving a multicast message at a router(105) and then determining multicast capabilities ofa mobile entity (ME) (113). An optimal multicast delivery mode is selected fordelivering a multicast message to the ME (113) atthe radio access network (107, 109, 111). The multicast message is thendelivered to the ME (113) at the radio access network (107,109, 111) according to the selected delivery mode.
