US 2010/0142430 A1 · MULTIMEDIA DATA SERVICE APPARATUS OF MOBILE COMMUNICATION SYSTEM SUPPORTING MULTICAST AND MULTICAST SERVICE ACTIVATION AND DEACTIVATION METHODS FOR MULTIMEDIA DATA SERVICE

Abstract

A multimedia data service apparatus of a mobile communication system for supporting multicast and multicast service activation and deactivation methods for a multimedia data service used by the mobile communication system are provided. Information for mobility management is searched for according to a multimedia data service join request from a packet data network gateway of the mobile communication system, and multimedia data is multicasted to a user equipment. Accordingly, a multicast service can be provided in a system of 3rd Generation Partnership Project (3GPP) Release 7 or later.
