METHOD FOR GENERATING AND MANAGING A SERVICE CONTEXT TO SUPPLY A MULTIMEDIA BROADCAST/MULTICAST SERVICE IN A MOBILE COMMUNICATION SYSTEM, CONCERNED WITH PREVENTING QOS INFORMATION OF MBMS DATA FROM BEING REPEATEDLY TRANSMITTED

摘要

PURPOSE: A method for generating and managing a service context to supply an MBMS(Multimedia Broadcast/Multicast Service) in a mobile communication system is provided to generate and manage an SRNC(Serving Radio Network Controller) MBMS context only within an RNC before starting a session. CONSTITUTION: A UE(410) sets an RRC connection with an RNC(421), and requests an MBMS through an SGSN(431)(400). If a packet domain service currently exists, the SGSN(431) transmits MBMS ID list information through an MBMS UE linking request message(410). After a session is started, the RNC(421) receives a session start message(440,441,450). The RNC(421) senses that the session is started(450), and stores QoS information and multicast area information received from the session start message(452). The RNC(421) generates a CRNC(Control RNC) MBMS context by using the QoS information and the multicast area information(453).
