Multimedia broadcast and multicast service paging
First Claim
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).

Abstract
This invention provides a paging method for Multimedia Broadcast/Multicast Service in mobile communication system paging process and radio resource setup process are merged in this method to try to reduce uplink responses. This invention extends existing PCH IubFP frame structure by adding MBMS Indication bit(MI) to PCH IubFP frame. The PCH IubFP frame includes Paging Indication (PI) and Paging Message. Paging message carries MBMS service information. MBMS Service Identity or MBMS Paging Indicator is added to the reserved 12 bits in Paging Indicator Channel (PICH) frame structure. Radio Network Controller (RNC) transfers Paging Indicator Message and paging message to Base Station (Node B) so as to send over the air-interface.
