Method for managing service context for paging user equipment in a multimedia broadcast/multicast service
First Claim
1. A method for providing MBMS (Multimedia Broadcast/Multicast Service) services to User Equipments (UEs), in a mobile communication system including a Node B, a plurality of the UEs capable of communicating with the Node B in a cell occupied by the Node B, and a radio network controller (RNC) for controlling communication of the Node B, a serving GPRS (General Packet Radio Service) support node (SGSN) for managing the RNC, and the UEs to provide a packet switched (PS) service and a circuit switched (CS) service to the UEs, the method comprising the steps of:
- transmitting MBMS service-related information of a UE that is in a Radio Resource Control (RRC) connected mode and a Packet Mobility Management-Idle (PMM-Idle) state after joining at least one MBMS service, from the UE to the RNC; and
receiving MBMS service by the UE according to the MBMS service-related information to enable the UE to inform the RNC that the user has joined at least one MBMS service.

Abstract
A method for managing information on user equipments (UEs) in a mobile communication system supporting an MBMS (Multimedia Broadcast/Multicast Service) service. A radio network controller (RNC) provides a packet switched (PS) service and a circuit switched (CS) service to the UEs. A UE that is in a Packet Mobility Management-Idle (PMM-Idle) mode after joining at least one MBMS service, transmits MBMS service-related information thereof to the RNC, and the RNC stores the MBMS service-related information in a first service context for the MBMS service held in the RNC, together with information on the UE.

11. A method for providing MBMS (Multimedia Broadcast/Multicast Service) services in a mobile communication system, the method comprising the steps of:
-
receiving, by a Radio Network Controller (RNC), a MBMS joined indication that a Packet Mobility Management-Idle (PMM-Idle) state User Equipment (UE) in a Radio Resource Control (RRC) connected mode has joined at least one MBMS service, from the UE; transmitting, by the RNC, an MBMS service IDentity (ID) request message containing an ID of the UE to a serving GPRS (General Packet Radio Service) support node (SGSN) managing the RNC; receiving, by the RNC, an MBMS service ID response message containing at least one service ID indicating at least one MBMS service that the UE has joined, from the SGSN; and providing MBMS service from the RNC to the UE according to the MBMS service ID response message. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method for providing MBMS (Multimedia Broadcast/Multicast Service) services to User Equipments (UEs), in a system including a Node B, a plurality of the UEs capable of communicating with the Node B in a cell occupied by the Node B, a radio network controller (RNC) for controlling communication of the Node B and the UEs to provide one of a packet switched (PS) service and a circuit switched (CS) service to the UEs, and a serving GPRS (General Packet Radio Service) support node (SGSN) for managing the RNC, the method comprising the steps of:
-
transmitting MBMS service-related information of a UE that is in a Packet Mobility Management-Idle (PMM-Idle) mode after joining at least one MBMS service, from the UE to the SGSN; linking the MBMS service-related information with information about the UE; and storing the MBMS service-related information linked to the information about the UE in a first service context for the at least one MBMS service in the SGSN. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)
