    Abstract: An embodiment provides a method for supporting video transmission and reception in a bitrate selection server of a mobile communication system. The method includes receiving a metadata request of a video from a terminal. The method also includes transmitting the received metadata request to a media server based on the request; receiving a metadata response from the media server. The method also includes storing the received video metadata and transmitting the received video metadata to the terminal. The method also includes requesting subscriber information of the terminal to a Policy and Changing Rules Function (PCRF) and receiving the subscriber information. The method also includes receiving a video segment request of the video from the terminal. The method also includes determining a bitrate of the video based on at least one of the video metadata and the subscriber information.

    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.

    Abstract: The present disclosure relates to a communication technique for fusing, with an IoT technology, a 5G communication system for supporting a higher data transmission rate than a 4G system, and a system therefor. The present disclosure may be applied to intelligent services, such as smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail businesses, and security and safety related services, on the basis of 5G communication technologies and IoT-related technologies. The present invention, according to one embodiment, may provide a method for requesting a service by a terminal, the method comprising the steps of: receiving, from a first network core, information for instructing a second network priority traffic; on the basis of the information for instructing the second network priority traffic, searching for a cell of a second network; and, if a cell accessible to the second network exists, transmitting a service request to the second network.

    Abstract: The present disclosure relates to a communication method and system for converging a 5G communication system for supporting higher data rates beyond a 4G system with an IoT technology. 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 provides 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. Through the present disclosure, a terminal (UE) can optimize a non-access stratum (NAS) signaling message, and can perform data transmission/reception with low latency.
