Abstract: Embodiments herein provide a method for managing CAG information. The method includes receiving, by an Access and Mobility Management Function (AMF), a registration request message from a User Equipment (UE) through a cell for registering to a network. Further, the method includes determining, by the AMF, that the UE is one of unauthorized to the cell when the cell is a CAG cell, and authorized to access the network only through a CAG cell when the cell is a non-CAG cell. Further, the method includes sending, by the AMF, a registration reject message to the UE, where the registration reject message includes a CAG information list.

Abstract: Methods and systems for handling emergency services in a wireless network. A method disclosed herein includes enabling at least one User Equipment (UE) supporting only Closed Access Group (CAG) cell/non-public network (NPN) to camp onto at least one non-CAG cell/public network cell to access the emergency services. The method further includes enabling the at least one UE to switch behavior of a timer from a periodic registration timer with a “Strictly Periodic Registration Timer Indication” to a normal periodic registration timer/pre-release 16 behavior for performing the emergency services.

Abstract: Accordingly, Example embodiments herein disclose a method for supporting a user equipment (UE) accessing one or more closed access group (CAG) cells via a radio access network. A core network apparatus may receive via the interface circuitry a request signal that includes a protected CAG identifier (ID) associated with the UE. The core network apparatus may de-conceal the protected CAG ID to determine a CAG ID. The proposed method can be used to define how the wireless communication system will perform the subscription check for the received CAG identifier. Further, the method can also be defined how to perform resume procedure on a CAG cell when the UE (100) is in a 5GMM-CONNECTED with inactive indication or 5GMM-IDLE with suspend indication.

Abstract: A method disclosed herein includes selecting, by the UE, a SNPN for registration, on the SNPN access mode being enabled. The method includes disabling, by the UE, the SNPN access mode, if the selected SNPN does not support at least one emergency service. The method includes enabling, by the UE, a Public Land Mobile Network (PLMN) selection mode to select a PLMN cell supporting the at least one emergency service, on the SNPN access mode being disabled. The method includes performing, by the UE, the at least one emergency service by camping on the selected PLMN cell. The method includes enabling, by the UE, the SNPN access mode for performing a SNPN selection procedure, on completion of the at least one emergency service.
