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: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Accordingly the embodiments herein provides a method and system for ciphering of initial NAS message protection procedure. A UE is registered to a first PLMN and a first 5G NAS security context has been established. The UE selects a second PLMN. The UE sends Initial Registration procedure with only cleartext IE to the second PLMN. The second PLMN may initiate and perform authentication procedure. The second PLMN initiates NAS Security mode control procedure and sends a Security Mode Command message containing the selected NAS ciphering method to the UE. The UE sends entire the Registration Request message containing both cleartext IE(s) and non-cleartext IE(s) using the NAS ciphering method sent in the Security Mode Complete message. The second PLMN send Registration Accept message.

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.
