Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. Embodiments herein disclose a method for providing restricted service access in a wireless network by a first network entity (i.e., target AMF entity (400)). The method includes requesting a NRF entity (600) to grant an access-token to access a second network entity (i.e., initial AMF entity (300)). Further, the method includes receiving a message comprising a restricted service access to the second network entity based on the access-token. Further, the method includes sending a restricted UE context transfer request to the second network entity based on the message comprising the restricted service access. Further, the method includes receiving a UE context transfer response from the second network entity based on the restricted UE context transfer request.

Abstract: Embodiments herein provide a method for handling synchronization of Home Network (HN) security key(s) in a wireless network. The proposed method includes receiving a Non-access stratum (NAS) authentication request message from a network entity (200A), where the UE (100A) holds a first Home network (HN) security key. Further, the method includes determining an authentication response message for the received NAS authentication request message and generating a second HN security key from a plurality of input parameters received in the NAS authentication request message and sending authentication response message to the network entity (200A). Further, the method includes storing the second HN security key in response to receiving a NAS security mode command message from the network entity (200A) or ignore the second HN security key in response to receiving a NAS reject message from the network entity (200A).

Abstract: 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.

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.
