Abstract:
Disclosed is a method for requesting and feeding back a multimedia broadcast multicast service (MBMS) state, the method being used for allowing a network side to inform a related user equipment (UE) to feed back MBMS state information and allowing the informed UE to feed back the MBMS state information. The request method comprises: when necessary to acquire the receiving state of an MBMS, a base station transmits, through a physical downlink control channel (PDCCH) scrambled by a radio network temporary identifier (RNTI) belonging specially to an MBMS service, or through a system message, a multicast control channel (MCCH) change notification to the UE; and the base station transmits an MBMS state report request to the UE through the changed MCCH. The present invention also discloses a device for implementing the method.
