    Abstract: The present invention relates to a communication technique for converging IoT technology with 5G communication systems for supporting higher data transmission rates than 4G systems and to a system therefor. The present disclosure can be applied to intelligent services (e.g., smart home, smart building, smart city, smart car or connected car, health care, digital education, retail business, security- and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The present invention proposes two methods, a method for resolving the congestion situation of a CN while keeping a terminal RRC-inactive and a method for resolving the congestion situation of a CN by switching a terminal to RRC-idle.

    Abstract: The present disclosure relates to a communication technique of fusing a 5G communication system for supporting higher data transmission rate beyond a 4G system with an IoT technology and a system thereof, and provides an intelligent service based on the 5G communication technology and the IoT related technology. A method of a terminal in a wireless communication system includes receiving, from an AMF, a first message including first information for identifying the AMF, the first information being assigned upon a successful registration to a first access; determining whether a second access is located in a same PLMN of the first access; and transmitting, to an access network entity of the second access, a second message requesting registration to the second access and including second information for identifying the AMF, in case that the second access is located in the same PLMN of the first access.

    Abstract: The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). According to an embodiment, a method performed by a UE is provided. The method comprises transmitting, to an access and mobility management function (AMF), information indicating that the UE supports network slice replacement feature, and in case that there is a protocol data unit (PDU) session associated with a single network slice selection assistance information (S-NSSAI) that needs to be replaced, receiving, from the AMF, a mapping of the S-NSSAI to an alternative S-NSSAI.

    Abstract: A method of a network function (NF) entity performing communication in a wireless communication system includes: in case that a first registration request of a user equipment (UE) for a slice is received at an access and mobility function (AMF) entity through a first network, receiving a first slice availability request message for the slice from the AMF entity; determining whether the slice is available for the UE, based on a network slice policy; and transmitting, to the AMF entity, a response message including information regarding slice availability of the UE according to the first registration request, wherein in case that a second registration request of the UE for the slice is received at the AMF entity through a second network, slice availability of the UE according to the second registration request is determined based on at least one of the network slice policy or the information regarding the slice availability of the UE according to the first registration request.

    Abstract: The disclosure relates to a method and a device for controlling a data rate in a network slice of a wireless communication system. A method for controlling a bit rate of a network slice by a session management function (SMF) device of a wireless communication system is provided. The method includes receiving a slice control policy information from a policy and charging function (PCF) device, transmitting, to a user plane function (UPF) device, a parameter for controlling each slice based on the received slice control information, and receiving, from the UPF device, a response signal for whether the transmitted parameter is acceptable.
