TRANSMISSION OF MULTICAST AND BROADCAST MULTIMEDIA SERVICES VIA A RADIO INTERFACE

摘要

The invention relates to a network element (23) for a radio access network (22) of a cellular network supporting the transmission of multicast and broadcast multimedia services via a radio interface Uu to user equipment (25), which network element (23) comprises radio interface protocols associated to different protocol layers including a data link layer (layer 2). In order to enable such transmissions, it is proposed that the data link layer comprises a dedicated multicast broadcast multimedia control sublayer (L2/MBMC) for a multicast broadcast multimedia control protocol (MBMC). The MBMC is to adapt multicast and broadcast multimedia services, originating from a core network of said cellular network, for transmission in the radio interface Uu. The invention equally relates to a corresponding radio access network, to a corresponding cellular network, to a corresponding user equipment, to a corresponding radio access based communication system, and to a corresponding method.
