Method of receiving MBMS service in wireless communication system and apparatus thereof
Disclosed are a method of receiving a MBMS service in a wireless communication system and an apparatus thereof. The method of receiving a Multimedia Broadcast/Multicast Service (MBMS) service in a wireless communication for supporting an MBMS, includes: receiving, by a User Equipment (UE), state information of an interested MBMS service provided by a preconfigured MBMS Point to Multipoint Radio Bearer (MRB) from a network; and determining, by the UE, whether to make a cell reselection priority of a MBMS frequency providing the interested MBMS service to be a highest priority according to the state information of the MBMS service.
1. A method of receiving a Multimedia Broadcast/Multicast Service (MBMS) service in a wireless communication for supporting an MBMS, the method comprising:
receiving, by a User Equipment (UE), a change notification indicating that state information of an interested MBMS service provided by a preconfigured MBMS Point to Multipoint Radio Bearer (MRB) from a network is changed from the network;
receiving, by the UE, the state information of the interested MBMS service; and
determining, by the UE, whether to make a cell reselection priority of a MBMS frequency providing the interested MBMS service to be a highest priority according to the state information of the interested MBMS service,
wherein the change notification is transmitted through a paging message, and
wherein a paging occasion and a paging cycle with respect to the paging message and a Paging Radio Network Temporary Identifier (P-RNTI) for identifying the paging message are dedicatedly defined in the MBMS service.
2. The method of claim 1 , wherein the state information of the MBMS service indicates an activation state to which data of the MBMS service are transmitted or indicates a deactivation state to which the data of the MBMS service are not transmitted.
3. The method of claim 2 , wherein the UE makes the cell reselection priority of the MBMS frequency providing the interested MBMS service to be the highest priority when the state information of the MBMS service indicates the activation state.
4. The method of claim 2 , wherein the UE does not change the cell reselection priority of the MBMS frequency providing the interested MBMS service when the state information of the MBMS service indicates the deactivation state.
5. The method of claim 1 , further comprising performing, by the UE, a cell reselection procedure.
6. The method of claim 1 , wherein the state information of the MBMS service is transmitted through one of system information, a Medium Access Control (MAC) Control Element (CE), or a paging message.
7. A User Equipment (UE) for receiving a Multimedia Broadcast/Multicast Service (MBMS) service in a wireless communication for supporting an MBMS, the UE comprising:
a Radio Frequency (RF) which transmits/receives a wireless signal; and
a processor,
wherein the processor:
receives a change notification indicating that state information of an interested MBMS service provided by a preconfigured MBMS Point to Multipoint Radio Bearer (MRB) from a network is changed from the network,
receives the state information of the interested MBMS; and
determines whether to make a cell reselection priority of a MBMS frequency providing the interested MBMS service to be a highest priority according to the state information of the interested MBMS service,
wherein the change notification is transmitted through a paging message, and
wherein a paging occasion and a paging cycle with respect to the paging message and a Paging Radio Network Temporary Identifier (P-RNTI) for identifying the paging message are dedicatedly defined in the MBMS service.
