Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for limiting a scope of authorization provided to a network function service consumer (NFC) device in a wireless network by a network repository function (NRF) server is provided. The method includes receiving an NF-registration request message from a network function producer (NFP) device. The NF-registration request message includes at least one of a set of the first information element indicating a single-network slice selection assistance information (S-NSSAI) of the NFC device allowed to access by the NFP device, a corresponding second information element indicating operations allowed on resources of the NFP device belonging to a S-NSSAI of the NFP device, and a third information element indicating a trust-level of the NFC device.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Methods and systems for handling network slice admission control for User Equipment (UE) are provided. The disclosure relates to network slicing and more particularly, to a system and method of ensuring that a communication system is able to accurately enforce quota on the maximum number of UEs concurrently registering for a network slice defined by a Single Network Slice Selection Assistance Information (S-NSSAI). The disclosure describes how the limits of “Number of Terminals” configured for an S-NSSAI may be accurately maintained in a Network Slice Admission Control Function (NSACF), and thus the enforcement may be performed when the limit is really exhausted. The disclosure also describes that a deregistration notification from a Unified Data Management (UDM) may act as a trigger for an old Mobility Management Function (AMF) to decrement counts in the NSACF as the old AMF is no longer serving the UE.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Disclosed is a method of performing slice management in a telecommunication network, wherein if a current slice is to be replaced by a replacement slice via a replacement procedure, the telecommunication network verifies if the current slice is undergoing or scheduled to undergo an authentication procedure, and if so, the replacement procedure is halted and the authentication procedure is progressed.

Abstract: Embodiments herein disclose a method and device for performing secondary re-authentication for a MA-PDU session in a wireless communication system. The method for performing authentication for a multi-access packet data unit (MA-PDU) session by a session management function+packet data network (PDN) gateway control plane function (SMF+PGW-C) in a wireless communication network is provided, the method comprises performing a procedure for secondary re-authentication of the MA-PDU session for a user equipment (UE) by selecting one of a first access type or a second access type in case that the SMF+PGW-C receives a re-authentication request from a data network-authentication, authorization, and accounting (DN-AAA) server, retrying a procedure for the secondary re-authentication of the MA-PDU session for the second access type in case that the SMF+PGW-C receives a failure indication for the secondary re-authentication that the UE is not reachable in the first access type, and retrying a procedure for the secondary re-authentication of the MA-PDU session for the first access type in case that the SMF+PGW-C receives a failure indication of the secondary re-authentication that the UE is not reachable in the second access type.
