Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by an AMF in a wireless communication system is provided. The method includes receiving, from a UE, requested NSSAI including a plurality of S-NSSAI, identifying whether each of the plurality of S-NSSAI is available, identifying a number of S-NSSAIs included in an allowed NSSAI; in case that the number of S-NSSAIs in the allowed NSSAI is less than a maximum number of S-NSSAIs for the allowed NSSAI, determining to include alternative S-NSSAI for a first S-NSSAI that is not available, and in case that the number of S-NSSAIs in the allowed NSSAI is at least equal to the maximum number of S-NSSAIs for the allowed NSSAI, determining S-NSSAIs for the allowed NSSAI based on whether the each of the plurality of S-NSSAI is associated with a PDU session.

Abstract: An embodiment of the present disclosure provides an operating method of a Session Management Function (SMF) entity in a wireless communication system. The operating method may include receiving, from an Access And Mobility Management Function (AMF) entity, a Protocol Data Unit (PDU) session creation request message, receiving, from a Unified Data Management (UDM) entity, subscriber information associated with a session of a user equipment (UE), transmitting, to the AMF entity, a response message with respect to the PDU session creation request message, selecting a Policy Control Function (PCF) entity, transmitting, to the selected PCF entity, a session management policy information creation request message comprising Session Migration Information, receiving, from the PCF entity, policy information about a PDU Session which is determined based on a maximum bitrate (MBR) value (UE-Slice-MBR) corresponding to a slice for the PDU Session, and selecting a User Plane Function (UPF) entity to support session continuity by considering an MBR, based on the policy information about a PDU Session.

Abstract: Methods and apparatus performed in a wireless communication system are provided. An attach request message for a first network supported by a user equipment (UE), is transmitted to a management entity. The attach request message includes first UE network capability information indicating support of a second network supported by the UE. An attach accept message indicating completion of attach to the first network is received from the management entity. A packet data network (PDN) connectivity request for the first network is transmitted to the management entity. A first session for the first network is established through a session management entity supporting mobility between the first network and the second network. In case that the UE supports the second network, regardless of enabled or disabled status of UE network capability for the second network, the session establishment request includes information related to a second session for the second network.

Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal in a mobile communication system is provided according to one embodiment of the present disclosure. The method comprises the steps of: transmitting a first message, comprising network function information of the terminal, to a mobility management entity associated with a first network; if the network function information instructs support for a second network, receiving a second message comprising connection reactivation request information from the mobility management entity; releasing the connection with respect to the first network in response to the second message; transmitting a third message, for reestablishing connection to the first network, to the mobility management entity on the basis of the connection reactivation request information. The third message comprises an identifier of a first session for the second network corresponding to the connection with respect to the first network allocated by the terminal.

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: The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate after a 4th generation (4G) communication system such as long term evolution (LTE). According to various embodiments, a method for operating a network node in a wireless communication system is provided. The method comprises obtaining slice policy information including a maximum data rate, monitoring a data rate of protocol data unit (PDU) sessions associated with the slice, determining whether a sum of data rates of PDU sessions associated with the slice exceeds the maximum data rate, transmitting, to a second network node, a policy enforcement request message for controlling the sum of data rates of the PDU sessions associated with the slice.
