    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 technique and system for combining 5G communication systems with IoT technologies to achieve a higher data rate beyond 4G systems. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail businesses, and security and safety related services) on the basis of 5G communication technologies and IoT related technologies. The disclosure provides a method for an electronic device to provide an augmented reality service. The method may include receiving content related information for an object; transmitting a request for at least one content among multiple contents related to the object based on filtering information and the content related information, and outputting at least one content received in response to the request in a virtual region.

    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.
