1. A method for managing a multicast group in a mobile communication system providing a multimedia broadcast/multicast service (MBMS) to a multicast group consisting of a plurality of terminals, comprising:

  • comparing movement information of a terminal and multicast group member information and determining whether to selectively notify a core network of the movement of the terminal based on the comparison, thereby minimizing unnecessary signaling from a network controller (RNC) to a core network,wherein if the terminal is moved to a multicast area (MA) that the RNC manages and the corresponding MA can provide an MBMS service, the RNC updates the multicast group member information and does not notify the core network of the movement of the terminal.
