Abstract: The present disclosure relates to a system and method of providing UE capability of supporting reception of multicast in Radio Resource Control_INACTIVE (RRC_INACTIVE) state. The method comprises sending an uplink-message to a communication network to register the UE's intention of joining a multicast session to receive a multicast service. Further a capability-indication is included in the uplink-message, where the capability indication indicates if the UE is capable of joining the multicast session in Radio Resource Control_INACTIVE (RRC_INACTIVE) state. Furthermore, the multicast service is received in the RRC_INACTIVE state based on capability negotiation between the UE and the communication network, in response to the capability indication.

Abstract: A method for performing a Network Slice Specific Authentication Authorization (NSSAA) procedure for a network slice is disclosed. The method includes performing, by a Network Slice Specific Authentication and Authorization Function (NSSAAF), an NSSAA procedure through a first Access and Mobility Management Function (AMF) selected amongst the first AMF and a second AMF. The method includes determining, by the NSSAAF whether the NS SAA procedure through the first AMF is successful or not. The method includes performing by the NSSAAF, one of skipping the NSSAA procedure for the second AMF in response to determining that the NSSAA procedure is successful for the first AMF transmitting a message to the second AMF for deleting Network Slice Selection Assistance Information (NSSAI) related to the network slice from an allowed list of network slices in response to determining that the NSSAA procedure is unsuccessful for the first AMF.

Abstract: Embodiments herein provide a method and a wireless network device (100) for handing a paging cause of a service. The method includes receiving, by the wireless network device (100), a NAS message includes the paging cause of the service provided by the wireless network device (100) and a first value corresponding to the paging cause from a UE (200). The method includes modifying, by the wireless network device (100), the first value of the paging cause of the service to a second value, and sending a NAS response message to the UE (200), where the NAS response message includes the paging cause of the service and the second value of the paging cause. The second value enables the UE (200) to respond to a paging message based on the second value of the paging cause.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments of present disclosure relates to methods and network system for managing network slice in communication network. Management entity of network system detects UEs having inactive sessions and releases the inactive sessions for UEs. Management entity transmits notification to UEs and to AMF entity of network system indicating release of inactive sessions. Management entity also transmits a request to AMF entity requesting deregistration of UEs having inactive sessions. Further, AMF entity identifies presence of any active sessions for UEs through other management entities for access type corresponding to UEs. AMF entity upon identifying absence of active sessions, deregisters network slice for UEs having inactive sessions. Thereafter, NSACF entity of network system updates parameters associated with network slice for managing network slice. Thus, the present disclosure aids in avoiding wastage of resources of the network slice.

Abstract: Embodiments of present disclosure relates to an apparatus and method for managing security context related to a UE. Initially, registration of a UE with a new AMF in a communication network is identified. Further, generation of new security context by new AUSF selected by the new AMF for authentication of the UE is detected. Further, presence of one or more old security contexts elated to the UE and generated by one or more old AUSFs selected by one or more old AMFs for one or more previous authentications of the UE, is detected. Upon the detection, de-registration of the UE with the one or more old AUSFs is initiated for managing security context related to the UE in the communication network. Thus, stale and inactive security context related to the UE may be deleted in the network and security of communication with the UE is enhanced.
