Multicast bearer management method and terminal device

A communication device, comprising:

• a receiver, configured to receive service data of a single cell-multimedia broadcast multicast service traffic channel (SC-MTCH);
• and
• a processor, configured to:
• when the receiver is in a process of reception of the service data of the SC-MTCH, suspend a single cell-multimedia broadcast multicast service point to multipoint radio bearer (SC-MRB) corresponding to the SC-MTCH when the receiver determines that it is to receive a first type of data,
• reserve a radio link control (RLC) entity corresponding to the SC-MRB, and release one of a media access control (MAC) layer configuration or a physical layer configuration corresponding to the SC-MRB, and
• when the receiver completes reception of the first type of data, restore or release the SC-MRB based on one of a temporary mobile group identity (TMGI) or a session identity corresponding to the SC-MRB.

A non-transitory computer readable storage medium storing program instructions, which, when executed by a processor, cause the processor to perform operations comprising:

• in a process of reception of service data of a single cell-multimedia broadcast multicast service traffic channel (SC-MTCH) by a terminal device, determining, by the terminal device, that the terminal device is to receive a first type of data;
• suspending, by the terminal device, a single cell-multimedia broadcast multicast service point to multipoint radio bearer (SC-MRB) corresponding to the SC-MTCH, wherein suspending the SC-MRB corresponding to the SC-MTCH further comprises reserving a radio link control (RLC) entity corresponding to the SC-MRB, and releasing one of a media access control (MAC) layer configuration or a physical layer configuration corresponding to the SC-MRB;
• and
• in response to determining that reception of the first type of data is completed, restoring or releasing the SC-MRB based on one of a temporary mobile group identity (TMGI) or a session identity corresponding to the SC-MRB.
