Method and apparatus for stopping and restarting MBMS service
First Claim
1. A method for communication related to a multimedia broadcast/multicast service (MBMS) service, the method performed by a user equipment (UE) and comprising:
- receiving multicast channel scheduling information (MSI) including a special value;
determining either a MBMS service stop or a MBMS service suspension, based on the special value included in the received MSI;
based on that the MBMS service suspension is determined, maintaining an MRB which is a radio bearer for providing the MBMS service;
after the determining either the MBMS service stop or the MBMS service suspension, establishing a unicast bearer; and
monitoring the MSI, an MTCH, or an MCCH based on that the MBMS service suspension is determined,wherein the monitoring is performed while the establishing the unicast bearer is being performed,wherein based on that the MBMS service stop is determined, resumption of the MBMS service is not considered by the UE, andwherein based on that the MBMS service suspension is determined, the resumption of the MBMS service is considered by the UE based on the maintaining of the MRB.

Abstract
Provided are a method and an apparatus for stopping and restarting an MBMS service in a wireless communication system. A terminal receives multicast channel (MCH) scheduling information (MSI) and checks whether a special value is included in the received MSI. If the special value is included in the MSI, then whether to stop or suspend the MBMS service can be determined. That is, MSI can be considered in stopping the MBMS service. Furthermore, stopping is terminating an MBMS service without a consideration for restarting same, and suspending is terminating an MBMS service with a consideration for restarting same.

9. A user equipment (UE) for communication related to a multimedia broadcast/multicast service (MBMS) service in a wireless communication system, the UE comprising:
-
a memory; a transceiver; and a processor, operatively coupled to the memory and the transceiver, wherein the processor is configured to; control the transceiver to receive multicast channel scheduling information (MSI) including a special value; determine either a MBMS service stop a MBMS service suspension, based on the special value included in the received MSI; and based on that the MBMS service suspension is determined, maintaining an MRB which is a radio bearer for providing the MBMS service; after the determining either the MBMS service stop or the MBMS service suspension, establish a unicast bearer; and monitor the MSI, an MTCH, or an MCCH based on that the MBMS service suspension is determined, wherein the monitoring is performed while the establishing the unicast bearer is being performed, wherein based on that the MBMS service stop is determined, resumption of the MBMS service is not considered by the processor, and wherein based on that the MBMS service suspension is determined, the resumption of the MBMS service is considered by the processor based on the maintaining of the MRB. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
