    Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transfer rate beyond a 4G communication system such as LTE. A terminal according to an embodiment of the present disclosure performs the operations of: transmitting a registration request message to a network node; receiving an authentication request message containing information on a security related capability from the network node; verifying the security related capability by using the authentication request message; transmitting a first message as a response to the authentication request message; receiving a security mode command message from the network node; and transmitting, to the network node, a security mode completion message as a response to the security mode command message, wherein the information on the security related capability includes information on a capability related to security between the terminal and the network node.

    Abstract: A method and an apparatus for supporting TSN in a wireless communication network are disclosed. The method for supporting fully-distributed time-sensitive networking (TSN) by a user plane function in a mobile communication system includes receiving a first status frame through a user equipment (UE) connected to a first TSN node, the first status frame including at least one of information about the first TSN node, information about a second TSN node for transmitting a data frame, stream information for transmitting data, and accumulated latency information; transmitting an update request for service quality (QoS) setup to a TSN application function (TSN AF) through a PDU session update procedure for the UE based on the received first status frame; and updating the first status frame upon receiving QoS setup information from the TSN AF, wherein the QoS setup information may include at least one of accumulated latency designated by the TSN AF, the status of the first TSN node, and the status of the second TSN node.

    Abstract: A method, performed by a network entity, of performing time sensitive communication (TSC) includes: establishing a first protocol data unit (PDU) session with a first user equipment (UE) and a second PDU session for a second UE; receiving, from the first UE, an announce message obtained from a first time sensitive network (TSN) node; configuring, based on the announce message, a port state of the network entity; and transmitting, to the second UE or a second TSN node, the announce message.

    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 invention provides a method of a SMF entity in a wireless communication system. The method comprises identifying whether to deactivate an UP connection of a first PDU session of one or more established PDU sessions, identifying whether the first PDU session supports an UP optimization based on the identification, and transmitting, to an AMF entity, a first message for deactivating the UP connection.
