Communication method, user equipment, non-transitory computer-readable medium, chipset and system

A user equipment for use in a mobile communication system that provides a multicast/broadcast service (MBS), the user equipment comprising:

• a controller configured to determine, in a Radio Resource Control (RRC) inactive state, whether a predetermined condition is satisfied in response to receiving a paging message comprising a session identifier of a multicast session from a network node;
• and
• a receiver configured to acquire, in the RRC inactive state, configuration information used for reception of the multicast session in the RRC inactive state by receiving a multicast control channel (MCCH) for multicast communication in response to the predetermined condition being satisfied.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a user equipment, cause the user equipment to perform processing comprising:

• determining, in a Radio Resource Control (RRC) inactive state, whether a predetermined condition is satisfied in response to receiving a paging message comprising a session identifier of a multicast session from a network node;
• and
• acquiring, in the RRC inactive state, configuration information used for reception of the multicast session in the RRC inactive state by receiving a multicast control channel (MCCH) for multicast communication in response to the predetermined condition being satisfied.
