Method and device for managing long-time switching timer in wireless communication system

A user equipment (UE) in a wireless communication system, the UE comprising:

• at least one transceiver;
• at least one processor communicatively coupled to the at least one transceiver;
• and
• at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor to cause the UE to:
• receive, from a base station, a first radio resource control (RRC) reconfiguration message including configuration information associated with the UE to leave an RRC connection state for a multi-universal subscriber identity module (MUSIM) operation, wherein the configuration information includes information associated with a timer for entering an RRC idle state without a response,
• in case that the UE needs to leave the RRC connection state, start the timer,
• receive, from the base station, a second RRC reconfiguration message, and
• in case that the timer is running, stop the timer, upon reception of the second RRC reconfiguration message.

A base station in a wireless communication system, the base station comprising:

• at least one transceiver;
• at least one processor communicatively coupled to the at least one transceiver;
• and
• at least one memory, communicatively coupled to the at least one processor, storing instructions executable by the at least one processor to cause the base station to:
• transmit, to a user equipment (UE), a first radio resource control (RRC) reconfiguration message including configuration information associated with the UE to leave a radio resource control (RRC) connection state for a multi-universal subscriber identity module (MUSIM) operation, the configuration information including information associated with a timer for the UE to enter an RRC idle state without a response;
• and
• transmit, to the UE, a second RRC reconfiguration message, wherein the second RRC reconfiguration message is associated with stopping the timer.
