Method and apparatus for reporting selected plmn of rrc-inactive mode ue in next-generation communication system

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

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to:
• reselect another equivalent public land mobile network (PLMN) in an inactive state,
• control the transceiver to transmit, to a base station, a radio resource control (RRC) resume request message including a resume cause configured to mobile originated (mo)-signaling in case that a radio access network (RAN)-based notification area update procedure is triggered, and
• control the transceiver to receive, from the base station, an RRC resume message.

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

• a transceiver;
• and
• at least one processor coupled with the transceiver and configured to:
• in case that another equivalent public land mobile network (PLMN) is reselected by an inactive-state user equipment (UE) and a radio access network (RAN)-based notification area update procedure is triggered,
• control the transceiver to receive, from a UE, a radio resource connection (RRC) resume request message including a resume cause configured to mobile originated (mo)-signaling, and
• control the transceiver to transmit, to the UE, an RRC resume message.
