METHOD AND APPARATUS FOR GROUP COMMUNICATION ROBUST TO MOBILITY |
摘要 |
The present invention relates to a method and an apparatus for group communication. More specifically, the present invention relates to a method and an apparatus by which a moving terminal can effectively participate in the group communication. A communication method for a base station in a mobile communication system, according to an embodiment of the present invention, can comprise the steps of: receiving MBMS bearer-related information including a QoS parameter from an MCE; updating bearer information on the terminal by using the received MBMS bearer-related information; determining a handover of the terminal and transmitting a handover request message including the MBMS bearer information, to a second base station incapable of supporting an MME or MBMS; transmitting a handover command message from the second base station to the terminal; and transmitting MBMS data to the second base station for a pre-set amount of time. According to an embodiment of the present invention, although the terminal moves to a region at which the MBMS is not provided, a group communication service is quickly provided through a PTP-type communication channel such that the terminal can seamlessly receive the group communication service. |
