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.

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: 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). A method for securing unicast message communication is provided. The method includes sending, by a user equipment (UE), a request-message for resuming radio resource control (RRC) connection to a base station, wherein the request message comprises a first-parameter defining “resume cause”. A response pertaining to at least one of network-release or network-resumption is received by the UE, wherein the response comprises a second parameter defining “resume cause”. Based on a successful-mapping between the first parameter and the second parameter, the response is acknowledged by the UE. However, for example, in case of network-rejection of the request due to network congestion, an RRC reject message comprising a first message authentication code is computed by the base station based on a stored network security context and communicated to the UE. Thereafter, a second message authentication code is mapped by the UE with the first message authentication code.
