Abstract
A radio access network facilitates transmission of a Multimedia Broadcast/Multicast Service (MBMS) to user equipments in plural cells served by a radio base station. A radio network controller includes in a first message of a transport channel setup request either an indication that transport sharing is allowed or an identification of a common transport bearer. The radio base station configures a new transport channel mapped to the common transport bearer such that it is stable with respect to other common transport channels. During operation, the radio network controller provides the MBMS data over the common transport bearer and the radio base station retransmits the MBMS data over the common transport channels to the plural cells. If the MBMS data over the common transport bearer arrives outside of time-of-arrival windows of any common transport bearer, then the radio network controller adjusts the transmission accordingly.
