  • Method for Multimedia Broadcast Multicast Service Linking for Pmm Idle Mobiles
    Publication number: 20070232308
    Abstract: A method and arrangement in a mobile telecommunication system for initiating a Multimedia Broadcast Multimedia Service (MBMS) to a User Equipment (UE) in Packet Mobility Management-idle (PMM-idle) mode controlled by a Radio Network Controller (RNC). The RNC is connected to a Serving GPRS Support Node (SGSN). The RNC indicates to the SGSN that the UE is transiting to a Circuit Switched connected mode. The RNC receives an MBMS UE context from the SGSN. The MBMS UE context is added to the RNC to make it aware that the RNC controls UEs connected to the MBMS.
