Abstract:
A communication system that includes a Multimedia Broadcast Multicast Service (MBMS) service provides re-broadcasts of an event to subscribers to the MBMS service. An infrastructure included in the communication system and comprising a server coupled to a RAN controller via a support node receives a first set of MBMS data from an MBMS content provider and conveys the first set of MBMS data along with an associated first Session Description to a subscribed mobile station. The infrastructure then receives a second set of MBMS data from the MBMS content provider, wherein the second set of MBMS data comprises a re-conveyance of the first set of MBMS data, and conveys an MBMS notification along with an associated second Session Description to the mobile station. The mobile station may then determine whether to receive the re-conveyance based on the first and second Session Descriptions.
