Abstract
One embodiment of the present invention relates to a method for providing, by a relay UE, a broadcast service in a wireless communication system, the method comprising the steps of: detecting a TMGI; and broadcasting TMGI announcement comprising the detected TMGI and a ProSe layer-2 group ID corresponding to the TMGI.
Claims8
A method of providing a broadcast service by a relay User Equipment (UE) in a wireless communication system, the method comprising:
- receiving, by the relay from a remote UE, a Temporary Mobile Group Identity (TMGI) monitoring request including a service description;
- transmitting, by the relay UE to the remote UE, a TMGI monitoring response including a Proximity Service (ProSe) layer-2 group ID and a TMGI Monitoring Refresh Timer;
- detecting, by the relay UE, a TMGI requested to monitor based on the service description;
- determining, by the relay UE, whether to provide a broadcast service to the remote UE, based on the relay UE detecting the TMGI;
- and
- based on the relay UE determining to provide the broadcast service to the remote UE, broadcasting, by the relay UE, a TMGI announcement including the ProSe layer-2 group ID and the TMGI Monitoring Refresh Timer corresponding to the detected TMGI and the detected TMGI,
- wherein the service description is related to a Multimedia Broadcast Multicast Service (MBMS),
- wherein the service description includes frequency information related to the MBMS, and
- wherein based on the TMGI announcement including a plurality of TMGIs, the TMGI announcement is configured to include only one PLMN (Public Land Mobile Network) ID for TMGIs having a same PLMN ID.
A relay User Equipment (UE) for providing a broadcast service in a wireless communication system, the relay UE comprising:
- a transceiver;
- and
- a processor that:
- controls the transceiver to receive, from a remote UE, a Temporary Mobile Group Identity (TMGI) monitoring request including a service description;
- controls the transceiver to transmit, to the remote UE, a TMGI monitoring response including a Proximity Service (ProSe) layer-2 group ID and a TMGI Monitoring Refresh Timer;
- detects a TMGI requested to monitor based on the received service description;
- determines whether to provide a broadcast service to the remote UE, based on the detection of the TMGI corresponding to the service description;
- and
- based on the relay UE determining to provide the broadcast service to the remote UE, broadcasts a TMGI announcement including the Proximity Service layer-2 group ID and the TMGI Monitoring Refresh Timer corresponding to the detected TMGI and the detected TMGI,
- wherein the service description is related to a Multimedia Broadcast Multicast Service (MBMS),
- wherein the service description includes frequency information related to the MBMS, and
- wherein based on the TMGI announcement including a plurality of TMGIs, the TMGI announcement is configured to include only one PLMN (Public Land Mobile Network) ID for TMGIs having a same PLMN ID.
