APPARATUS AND METHOD FOR SUPPORTING PERIODIC MULTICAST TRANSMISSION IN MACHINE TO MACHINE COMMUNICATION SYSTEM

摘要

A method and apparatus for effectively transmitting periodically generated group data of a serving group in a Machine to Machine (M2M) communication system are provided. A method includes determining whether a persistent resource for group data of an M2M communication service group is allocated, if the persistent resource is not allocated, configuring the persistent resource for the group data and transmitting allocation information for the persistent resource to at least one Subscriber Station (SS) registered to the service group, and multicasting the group data to the at least one SS by using the persistent resource.
