    Abstract: Methods and systems for triggers of leaving procedure methods and systems for triggers of leaving procedure. The method includes receiving, by the UE, an RRC signaling connection release from a wireless communication network. The RRC signaling connection release indicates that the UE moves to an RRC inactive state. The UE is in a multi-user services identity module (MUSIM) mode. The method includes determining, by the UE, if there is an activity over 3GPP access due to another USIM. The method includes transmitting, by the UE, a non-access stratum (NAS) message including a service request message. The method includes triggering, by the wireless communication network, a release procedure to transfer the UE to an IDLE state in response to receiving the services request message in 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 present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.
    Methods and systems for handling encoding of radio capability information of UE using RACS. A method disclosed herein includes encoding radio capability information of a user equipment (UE) in formats of multiple radio access technologies (RATs) that have been supported by a public land mobile network (PLMN) in which the UE is registered. The method further includes assigning a radio capability identifier (RAC-ID) to the UE for signalling the radio capability information encoded in the multiple formats across the multiple RATs. The method further includes encoding the radio capability information in a specific format of the indicated RAT and assigning the RAC-ID to the UE for signalling the radio capability information and the associated encoding format.
