    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.

    Abstract: Disclosed herein are a communication technique for merging, with an IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system; and a system therefor.
    Embodiments herein disclose a method of protecting sensitive user plane traffic in an User Equipment (UE) (100), the method comprising: transmitting, to a network (200), by the UE (100) a first NAS message comprising an indicator indicating that the UE (200) supports of a secure channel for domain name system (DNS); receiving, from the network (200), by the UE (100) a second NAS message including DNS server security information in response to transmitting the first NAS message; and transmitting, to the network (200), by the UE (100) the DNS over the secure channel based on the DNS server security information.

    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. Disclosed is a method of determining, in a User Equipment, if a PDU session between the UE and a network, can be transferred between 3GPP and non-3GPP access, when the UE is using a Cellular Internet of Things, CIoT, optimisation, wherein the determination is performed on the basis of a Control Plane, CP, only indication and if the determination is positive, then the PDU session is not transferred.

    Abstract: The present disclosure relates to a method and a system for Non-3GPP Interworking Function (N3IWF) selection in a UE for network connectivity. The method comprising receiving, by the UE associated with the system, a configuration message from an AMF in a network. Thereafter, the method comprising configuring each of a plurality of N3IWF identifiers and associated at least one S-NSSAI present in the configuration message, wherein the each of the plurality of N3IWF identifiers is an IP address or a FQDN. Subsequently, the method comprising selecting a N3IWF identifier from the plurality of N3IWF identifiers based on a user selection of a S-NSSAI associated with the N3IWF identifier for the network connectivity. The present disclosure makes user aware of the different N3IWFs available in the network, which allows user to select right N3IWF, and hence, the services the user wants to utilize while connecting via non-3 GPP network.
