<p>Network-assisted solutions are provided to maintain MBMS service continuity. In one novel aspect, a base station broadcasts MBMS service continuity (SC) indication to a plurality of user equipments (UEs) via a system information block (SIB). The MBMS SC indication comprises MBMS service area IDs (SAIs) supported by the current cell as well as neighbor frequencies. If a UE is in RRC_IDLE state, then the UE makes cell reselection decision based on the MBMS SC indication to maintain MBMS service continuity. If the UE is in RRC_CONNECTED state, then the UE reports MBMS reception status to the base station based on the MBMS SC indication via a dedicated RRC message. As a result, the base station can makes certain decisions including handover for the UE to maintain MBMS service continuity.</p> |
