Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Method and system for supporting protection of MBS traffic in wireless network. Embodiments herein disclose a method and a system for supporting protection of Multi-cast Broadcast Service (MBS) traffic in a wireless network. The method includes receiving security information in a MBS announcement by user equipment (UE) (100). The method includes determining if MBS traffic protection is applied or not over the service layer; determining whether security capability of the MBS supports handling of the MBS traffic protected at the service layer, when the MBS traffic protection is applied over the service layer; joining a MBS session by sending a Non-access stratum (NAS) request message to a session management function (SMF) device (200), and requesting for the 5GC individual traffic delivery method by including an indication in the NAS request message, if the security capability of the MBS does not support handling of the MBS traffic protected at the service layer; and receiving the MBS traffic via 5GC individual traffic delivery method.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose methods for managing a paging operation in a wireless network (1000) by a UE (100). The method includes receiving a paging message from a network device (200), where the UE (100) is in a Radio Resource Control (RRC) inactive state. Further, the method includes determining whether the UE (100) has received at least one of a core network (CN) paging and a group paging in the paging message. Further, the method includes sending at least one of a UE identity, an access type and a Temporary Mobile Group Identity (TMGI) to an upper layer upon determining that the UE (100) simultaneously receives the CN paging and the group paging in the paging message. Further, the method includes transiting the UE (100) into a Radio Resource Control (RRC) idle state from the RRC inactive state.

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 5th generation (5G) or 6th generation (6G) communication system for supporting a higher data transmission rate. A method for handling a Non access stratum (NAS) procedure (e.g., service request (SR) procedure or the like) by a user equipment (UE) in a wireless network is provided. The method includes triggering the SR procedure and determining a transmission failure of the SR or a control plane service request message in response to triggering the SR procedure. Further, the method includes determining whether the SR procedure is triggered for a reason comprising one of requesting the wireless network to release a NAS signaling connection, and rejecting a paging request from the wireless network, or requesting the wireless network to release the NAS signaling connection. Further, the method includes performing one of aborting the SR procedure triggered due to the reason in response to determining the transmission failure, or re-triggering the SR procedure triggered not due to the reason in response to determining the transmission failure.
