Abstract:
1. A method of paging UEs to provide MBMS service in mobile communication system, the method comprises steps of: (a) Broadcast and multicast service center (BM-SC) sending data to Service GPRS Supporting Node (SGSN) via Gateway GPRS Supporting Node (GGSN); (b) After Service GPRS Supporting Node (SGSN) receives data from Gateway GPRS Supporting Node (GGSN), it sending MBMS notification to Radio network controller (RNC); (c) After RNC receives the notification from SGSN, it organizing the frame according to a paging channel (PCH) Iub frame protocol (FP) according to the notification, wherein the frame includes a MBMS Indicator bit (MI) to the frame of the frame protocol (PCH IubFP), which includes MBMS PI and paging message; (d) Radio Network Controller (RNC) sending the frame of frame protocol (PCH IubFP) to Base Station (Node B); and (f) Base Station (Node B) transmitting a Temporary MBMS Group Identity (MBMS TMGI) or MBMS Paging Indicator (PI) to by using the last 12 bits of a paging indicator channel (PICH) and Secondary Common Control Physical Channel (SCCPCH) frame that carries paging message for User Equipment (UE).
