    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: 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.

    摘要: Provided is a method including: receiving a request for one or more first network slices to be accessed by a terminal; receiving terminal subscription information including information about one or more third network slices subscribed as a default; identifying whether one or more second network slices subscribed by the terminal included in the one or more first network slices are an authentication procedure target; when all of the one or more second network slices are the authentication procedure target, adding all of the one or more second network slices to a pending network slice list; performing an authentication procedure based on at least one of the pending network slice list or the one or more third network slices; and determining, based on a result of the authentication procedure, one or more network slices available to the terminal.

    摘要: The disclosure relates to a communication technique of converging a 5th generation (5G) communication system for supporting higher data rates after a 4th generation (4G) system with Internet of things (IoT), and a system therefor. The disclosure provides a method performed by a first network entity managing a packet data network (PDN) session in a wireless communication system supporting interworking between a first and second networks. The method comprises receiving subscription update information of a user equipment (UE) for which a PDN connection associated with a network slice is established in the second network, the network slice being subscribed in the first network, determining whether to release the PDN connection if the subscription update information includes information notifying that network slice related information of the UE is changed, and performing a release of the PDN connection associated with the network slice if the release of the PDN connection is determined.
