Abstract: Provided are multicast services to a direct communication terminal not connected to a base station. Upon receiving a multicast packet from the base station, a forwarding terminal connected to the base station establishes a multicast connection with at least one direct communication terminal having a direct communication group identifier mapped to a multicast IP address of the multicast packet, and transmits the multicast packet to the at least one direct communication terminal.

Abstract: PURPOSE: A method and a device for managing multicast resources efficiently provide limited resources for a plurality of users. CONSTITUTION: A resource manager (710) allocates a multicast resource to a multicast group, and generates a MAP information element (MAP IE). The MAP IE includes information of the multicast resource and a transmission indication for indicating whether the multicast resource is fragmented. A transmitter (720) transmits the MAP IE to the multicast group. The MAP IE further includes an allocation period indicating a period in which the multicast resource is allocated, and an expiry date in which allocation of the multicast resource is maintained.
