In a UE configuration update procedure initiated by a network, when the UE is connected to the network via a satellite, one or more forbidden tracking area identities (TAIs) in a 5G system (5GS) forbidden tracking area information element for roaming and/or regional provision of service are included and transmitted in a configuration update command message transmitted by a 5G core network to the UE to provide an appropriate procedure for updating a tracking area identity (TAI) list stored in the UE while the UE in a 5GMM connected mode maintains a registered state.
