Publication number: 20240163665Abstract: 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.Type: ApplicationFiled: March 17, 2022Publication date: May 16, 2024Inventors: Ashok Kumar NAYAK, Rajavelsamy RAJADURAI, Varini GUPTA, Hoyeon LEE

Patent number: 11963095Abstract: 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.Type: GrantFiled: April 7, 2022Date of Patent: April 16, 2024Assignee: Samsung Electronics Co., Ltd.Inventors: Varini Gupta, Ashok Kumar Nayak, Danish Ehsan Hashmi, Hoyeon Lee, Lalith Kumar
