    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: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). The embodiments in the present disclosure allow to transfer remaining data between different base stations in a dual-registration interworking process, which provides terminal mobility between 4G and 5G networks without a data loss. Further, it provides the terminal mobility with no data loss without changing 5G and 4G base station implementation through addition of a simple function of new equipment, such as SMF and UPF. Further, it supports different QoS and forwarding path units in the 5G/4G networks without changing 5G and 4G base station functions. Further, it exempts additional function implementation costs for re-ordering in a terminal and a network through in-order delivery of packets to the terminal without changing the packet order during 4G-5G network movement.

    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.
