Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE).
Embodiments herein disclose a method performed by a terminal in a mobile communication system. The method includes performing a registration procedure on a first standalone non-public network (SNPN), selecting a second SNPN based on a predetermined condition, and transmitting, to a network entity, a registration request message on the second SNPN for an initial registration, in case that the second SNPN differs from the first SNPN.

Abstract: Accordingly, embodiments herein disclose a method for handling a closed access group (CAG) related procedure in a wireless communication system. A network may receive a radio resource control (RRC) resume request message from a user equipment (UE). The network may determine whether the at least one CAG identifier (ID) broadcasted in a CAG cell is included in an allowed CAG list of the UE (100) in response to the RRC resume request message. The network may proceed with a RRC resume procedure in response to determining that the at least one CAG ID is included in the allowed CAG list.

Abstract: This disclosure provides a method for providing user equipment (UE) radio access capabilities in a handover procedure. The method includes identifying, by a source next-generation radio access network (NG-RAN), that a target public land mobile network (PLMN) does not support a UE radio access capabilities identifier (RAC ID) assigned by a source PLMN in an inter-PLMN handover procedure. Further, the method includes providing, by the source NG-RAN, to a target NG-RAN, the UE radio access capabilities instead of the UE RAC ID in response to identifying that the target PLMN does not support the UE RAC ID assigned by the source PLMN.

Abstract: Methods and systems for controlling permissions of a UE for accessing a network. A method disclosed herein includes initiating, by a User Equipment (UE), a registration procedure with a serving network for accessing a selected network, wherein the selected network includes one of at least one CAG cell of an NPN and a VPLMN. The registration procedure indicates a network selection mode using which the UE has selected the network and the network selection mode includes one of an automatic mode and a manual mode. The method further incudes determining, by the serving network, a reject mode for rejecting the registration request of the UE based on the network selection mode indicated in the registration request, when the permissions of the UE to access the selected network have not been verified, wherein the reject mode includes a protected reject mode and an unprotected reject mode.

Abstract: A method for managing a Closed Access Group (CAG) feature using an Access and Mobility Management Function (AMF) server. The method includes receiving a registration request message from a User Equipment (UE) for registering for a CAG subscription. The method includes determining that the UE is subscribed to access the network through a CAG cell only. The method includes determining whether the registration request message includes a CAG support indicator. The method includes determining whether the UE supports the CAG feature based on the CAG support indicator. The method includes sending either a registration accept message including a CAG information list to the UE when the UE supports the CAG feature, or a registration reject message including a 5GMM cause value other than a 5GMM cause #76 to the UE when the UE does not support the CAG feature.
