Methods for binding and unbinding a MBMS bearer to a communication group in a 3GPP compliant system

摘要

A 3GPP compliant system includes a radio access network (RAN) partitioned into a plurality MBMS services areas, wherein each MBMS service area has a plurality of MBMS bearers established a priori for transporting media streams. An infrastructure device: receives a request to transmit a media stream to a communication group, wherein the request to transmit is received after the MBMS bearers were established; determines a MBMS bearer in a MBMS service area to assign to transport the media stream; generates a MBMS connect message that binds the communication group to the assigned MBMS bearer, wherein the MBMS connect message includes an identifier for the communication group and an identifier for the assigned MBMS bearer; and sends the MBMS connect message to members of the communication group.
