APPARATUS AND METHOD FOR RECEIVING AND TRANSMITTING CONTROL MESSAGE OF MULTIMEDIA BROADCASTING SERVICE IN MOBILE COMMUNICATION SYSTEM

摘要

The present invention relates to a method and apparatus for transmitting and receiving a control message of a multimedia broadcasting service in a mobile communication system, and more particularly, to a method and apparatus for receiving a control message of a multimedia broadcasting service in a mobile communication system having control channels for a plurality of multimedia broadcasting services The method comprising the steps of: determining a mapping relationship between a plurality of control channels and a bitmap and setting a corresponding bitmap in a notification message; receiving the notification message transmitted from the base station; Analyzing the map according to the mapping relationship, selecting at least one control channel among the control channels for the multimedia broadcasting service, and receiving control information of the control channel. According to the present invention, unnecessary reception of control messages is minimized, thereby extending the battery life of the terminal.;Long Term Evolution (LTE), Mutlimedia Broadcast Multicast Service (MBMS), Protocol Data Unit (PDU), Notification, BITMAP
