USE OF BROADCAST/MULTICAST FOR M2M AND MTC COMMUNCATIONS

摘要

A wireless communications system sends an multimedia broadcast multicast service (MBMS) wakeup indication to a user equipment (UE) or a group of UEs informing the UEs of an upcoming multicast/broadcast session. A UE may be a member of one or more groups and may be configured to wake up for the upcoming multicast/broadcast session and to receive multicast/broadcast data during the session using MBMS technology, if the data to be multicast/broadcast corresponds to one of the one or more groups of which the UE is a member. The system multicasts/broadcasts the data intended for receipt by a group of UEs through at least one multicast/broadcast mechanism.
