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: Provided are a method and apparatus for transmitting and receiving media. A method of transmitting and receiving media segments for a base station may include: receiving a segment request message from a user equipment; checking whether the segment request message contains a segment selection delegation indicator through analysis of the segment request message; obtaining, when the segment request message contains a segment selection delegation indicator, play position information from the segment request message; selecting one of two or more segments corresponding to the play position information; and receiving the selected segment from an external server and delivering the received segment to the user equipment. Embodiments of the present invention enable efficient adaptive streaming.
