    Abstract: The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate than a 4th generation (4G) communication system such as Long Term Evolution (LTE). According to various embodiments, there is provided an operating method of an application function (AF) in a wireless communication system that includes: transmitting, to a network exposure function (NEF), a Nnef_EventExposure_Subscribe message including an address of a user equipment (UE) to request a subscription of a user plane function (UPF) event exposure service for the UE; and receiving, from the NEF, a Nnef_EventExposure_Notify message including information on the UPF event exposure service for the UE.

    Abstract: The disclosure relates to a 5th generation (5G) or pre-5G communication system to support a higher data rate after a 4th generation (4G) communication system such as long term evolution (LTE). Various embodiments provide a method for operating a terminal in a wireless communication system, the method including: transmitting a PDU session establishment request message to a network node; receiving a PDU session establishment accept message from the network node; and determining a PDU session as an always-on PDU session for an URLLC service.

    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. According to one embodiment of the present invention, the present invention comprises the steps of: an access and mobility management function (AMF) of a 5G core network determining whether a terminal has moved to an area in which packet transmission/reception is possible, or an area in which packet transmission/reception is impossible; transmitting a message including information on the determination result to a session management function (SMF); and transmitting a response message including information associated with a change in the state of a session to the terminal. In addition, the present invention relates to a method and a device for blocking or allowing the transmission/reception of a packet transmission session (PDU session) according to the position of a terminal in a 5G system. In a 5G system, a local area data network service by which a packet session is valid only in a specific area will be supported, and a method is required for allowing the transmission of a packet of a session only in an area that can be divided into a cell or a tracking area. Additionally, in a 5G system, an allowed area in which the transmission/reception of a packet of a session according to each position of a terminal is allowed, and a non-allowed area in which same is not allowed are present, and thus packet transmission may be allowed or not according to area. In order to provide such service, the present invention provides a procedure whereby the state of a session is defined in a packet transmission non-allowed area, and a change in the state of the session occurs when moving from a packet transmission-allowed area to the non-allowed area.

    Abstract: A communication method and system converges a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. The system and method 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. Embodiments provide a scheme for efficiently operating an UP connection of a session in case where a terminal has a plurality of sessions in a mobile communication system, such as a 5G system, having a network structure in which an AMF for mobility management and an SMF for session management are separated from each other. A terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission/reception with low latency.

    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. The present disclosure further relates to a method by a session management function (SMF) in a network including a session that is established via a first user plane function (UPF). The method includes determining whether to change the first UPF to a second UPF, and transmitting, to a terminal via an access and mobility function (AMF), a first message including a maintain time of the session established via the first UPF, when the first UPF needs to be changed.
