    Abstract: The present disclosure realtes 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). In an embodiment, a method, for managing an Authentication and Key Management for Applications (AKMA) service for a User Equipment (UE) in a communication system is disclosed. The method includes determining, by a network function, that the UE is not allowed to utilize the AKMA service, in response to detecting at least one condition associated with the UE. The method includes transmitting, by the network function, a request to an AKMA Anchor Function (AAnF) for deleting an AKMA context corresponding to the UE from a memory associated with the AAnF. The method includes deleting, by the AAnF, the AKMA context corresponding to the UE from the memory.

    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.
