A METHOD FOR MULTIMEDIA BROADCAST MULTICAST SERVICE LINKING FOR PMM IDLE MOBILES

摘要

The present invention relates to methods and arrangements in a mobile telecommunication system for initiating a Multimedia Broadcast Multimedia Service (MBMS) to a User Equipment (UE) in PMM-idle mode controlled by a Radio Network Controller (RNC) wherein the RNC is connected to a Serving GPRS Support Node (SGSN). The method in the RNC according one of the embodiment comprises the steps of: (a)- indicating to the SGSN that the UE transits to the Circuit Switched connected mode, (b)-receiving from the SGSN an MBMS UE context, and (d)- adding MBMS UE context in the RNC to make the RNC aware of that it controls UEs connected to the MBMS.
