CONTINUITY PROVIDING APPARATUS AND METHOD FOR MULTICAST SERVICE

摘要

PURPOSE: A device and a method capable of providing continuity of multicast service are provided to minimize cut of the multicast service when inter-cell occurs on a sleep mode terminal receiving the multicast service. CONSTITUTION: A wireless bearer information receiver unit(310) periodically receives the wireless bearer information about the multicast service from the source base station and stores it. If the hand over occurs among the reception of the multicast service packet, a service support decision unit(320) decides the multicast service support of a target base station. In case the target base transceiver station supports the multicast service, a wireless bearer information setting unit(330) sets the wireless bearer information about the recently received multicast service.
