Abstract: Accordingly, the embodiments herein provide a method for authentication of an IAB node by an IAB-donor node in a wireless network. The method includes obtaining an IAB authorization information of the IAB node from one of an Access and Mobility Management Function (AMF) and a Mobility Management Entity (MME) of the wireless network, determining whether the IAB authorization information of the IAB node indicates the IAB node is authorized, and allocating a unique identity/parameter to the IAB node during an IAB-Mobile Termination (MT) setup and/or Backhaul Radio Link Control (RLC) channel establishment and/or Routing update phase. Further, the method includes storing the unique identity/parameter in a user equipment (UE)-context, which is used to identify the UE-context during an IAB-Distributed Unit (DU) part setup for authorization check and/or authentication.

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: 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.
