摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for handling registration of a UE by a network apparatus, includes determining a list of NSSAI to which the UE connects to receive at least one service an indication for each single NSSAI(S-NSSAI) in the list of configured NSSAI to indicate whether the UE needs to attempt to connect to that S-NSSAI upon receiving the list of configured NSSAI, and transmitting a message including the list of configured NSSAI and the indication to the UE.

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose a wireless network and methods to maintain a MA PDU session at a NSACF entity. The method includes determining, by a SMF entity, that a PDU session is the MA PDU session based on an indication from a UE. Further, the method includes indicating, by the SMF entity, that the PDU session is the MA PDU session to the NSACF entity in response to determination. The wireless network may maintain the count accurately even though the PDU session is a MA PDU session.

摘要： 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.

摘要： Embodiments herein provide methods for providing priority services to a UE by an AMF. The method includes receiving a request message from the UE, receiving, from a unified data management (UDM), subscription data of the UE, and, based on identifying that the subscription data comprises information related to a priority service and the request message does not include an establishment cause associated with the priority service, sending, to the UE, an accept message for the priority service in response to receiving the request message. The priority service comprises at least one of multimedia priority service (MPS) or mission critical service (MCX).

摘要： The present disclosure relates to the field of network slicing in wireless communication. In accordance with an aspect of the disclosure, a method performed by an access and mobility function (AMF) entity is provided. The method includes receiving, from a user equipment (UE), a registration request including a requested network slice selection assistance information (NSSAI); transmitting, to a Network Slice Admission Control Function (NSACF) entity, a request for determination of an availability of a number of UEs based on the registration request; and in case that a rejection for the request is received from the NSACF, transmitting, to the UE, information on a back-off timer.

摘要： 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.

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein provide method for managing a Network Slice Selection Assistance Information (NSSAI) list in a wireless network by a UE. The method includes receiving at least one event. The at least one event includes: receiving a deregistration request message from a network function (NF) entity, performing a deregistration event at the UE, or successfully completing a tracking area update procedure, a successful registration procedure, or an unsuccessful registration procedure. Further, the method includes deleting: a partially rejected NSSAI list or a partially allowed NSSAI list based on the at least one received event.

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for selecting correct SMF for SNPN onboarding of a UE (100) by a NRF apparatus (300). The method includes receiving a NF profile from a SMF apparatus of a plurality of SMF apparatuses (400a and 400b). Further, the method includes receiving a discovery message for SMF supporting the SNPN Onboarding service and at least one of DNN service and S-NSSAI service from an AMF apparatus (200). Further, the method includes selecting the at least one apparatus of the plurality of SMF apparatuses (400a and 400b) supporting the SNPN Onboarding service and at least one of the DNN service and the S-NSSAI service based on the NF profile received from each SMF sever of the plurality of SMF apparatuses (400a and 400b). Further, the method includes sending the at least one selected SMF apparatus to the AMF apparatus (200).

摘要： The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for NSAC based on availability of a quota at a NSACF apparatus in a wireless network. The method includes registering, by an AMF apparatus or a SMF apparatus, a plurality of UEs to at least one network slice requiring admission control; detecting, by AMF apparatus or SMF apparatus, enablement of a configuration to perform the admission control on an already deployed existing slice based on availability of the quota at NSACF apparatus in the wireless network; sending, by AMF apparatus, a number of UEs per slice update request message to NSACF apparatus to increase a count of the quota for the already registered UEs.
