A system and method for signaling the availability of a Multimedia Broadcast/Multicast Service (MBMS) user service in multiple variants. Various embodiments involve the usage of the additional capacity introduced by MBMS Over a Single Frequency Network (MBSFN) in order to carry a higher quality or more robust variant of the service in MBMS. The broadcast multicast service center (BM- SC) provides the same MBMS user service in two variants, one for the regular MBMS and the other for MBSFN. The MBSFN variant of the service may be charged differently and would then need to be protected separately. In various embodiments, the user equipment is informed that the same service is present in different variants and therefore can then select one of the available variants for consumption. |
