Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide method for enforcing NSSRG in EPS by first network entity. The method includes receiving a PDN connection request with APN from UE. The method includes detecting whether any earlier PDN connection for UE is being handled by the first network entity or at least one second network entity. In an embodiment, when earlier PDN connection for the UE is handled by first network entity or the second network entity, the method includes applying NSSRG information for the PDN connection, selecting a S-NSSAI from a plurality of S-NSSAIs that is compatible to a S-NSSAI having same NSSRG information from the plurality of S-NSSAIs used to handle the earlier PDN connection by the network entity, and allocating the selected S-NSSAI to the UE to establish the PDN connection with the APN using allocated S-NSSAI.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein provide a method for managing aerial information of an UUAA context in a wireless network (1000) by a network device (600). The method includes storing an UUAA Mobility Management (UUAA-MM) context or UUAA Session Management (UUAA-SM) context when an UAV (100) is authenticated and authorized for an Uncrewed Aerial System (CAS) service in the wireless network. Further, the method includes detecting an event associated with an UAV (100) in the wireless network. Further, the method includes removing the stored UUAA-MM context or UUAA-SM context for the UAS service for the UAV (100) in response to detecting the event. Further, the method includes transmitting a message to an UASNF device (300) to unsubscribe for the UAS service for the UAV or to remove the UUAA-MM context or UUAA-SM context stored at the UASNF device (300) for the CAS service for the UAV.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments disclosed herein relate to methods and systems for updating a partially allowed network slice selection assistance information (NSSAI) list, and managing a congestion timer/back-off timer for an alternative single-NSSAI (S-NSSAI) in wireless communication networks. The methods include removing network slice support information stored in a user equipment (UE), if a Non-Access Stratum (NAS) message from a network indicates to delete the network slice support information. The methods include applying a back-off timer to the S-NSSAI to be replaced (S-NSSAI-1)/alternative S-NSSAI (S-NSSAI-A)/combination of S-NSSAI-A+S-NSSAI-1, on receiving a Packet Data Unit (PDU) session establishment request, when the network is congested. The methods include applying a back-off timer to the S-NSSAI-A/S-NSSAI-1/combination of S-NSSAI-A+S-NSSAI-1, on receiving a congestion timer from the network function while requesting an alternative S-NSSAI

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an AMF entity in a wireless communication system, the method comprising: identifying whether a first LADN service area for a DNN and S-NSSAI is removed, and transmitting, to a SMF entity, a message for requesting a release of an ongoing PDU session subjected to an LADN in case that the first LADN service area is removed.

Abstract: 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.

Abstract: 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.

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: 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).

Abstract: Methods and system for managing temporary slice deployment in 3GPP. Embodiments herein disclose systems and methods for managing temporary slice deployment in 3GPP. The operator or slice owner can commission the Network Functions (NFs) with validity criteria of temporary network slices. On expiry of the validity criteria, the NFs will decommission the temporary network slice. When the UE requests for these temporary network slices, the Access and Mobility Management Function (AMF) provides the UE with the temporary network slices along with its validity criteria. Before expiry of the validity criteria, the UE releases an ongoing protocol data unit (PDU) session, and then removes the network slice on expiry of the validity criteria. The UE will only be able to access services from the temporary network slice if the UE is located in the temporary network slice's service area.

Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. Embodiments herein disclose methods and systems for managing a user equipment (102) in a wireless network (100). Embodiments disclose initiating, by a Session Management Function (SMF) (106), secondary re-authentication of the UE for existing protocol data unit (PDU) session based on at least one local policy at the SMF associated with DN or based on a configuration in the subscription profile of the UE for the associated DN. Embodiments disclose updating, by the SMF, at least one re-authentication status parameter to a pending state, on receiving a failure message from an Access and Mobility Management Function (AMF) (104) if the UE is unreachable. Embodiments disclose triggering, by the SMF, the re-authentication of the UE for the same existing PDU session, on identifying by the AMF that the UE is reachable.
