Abstract: The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method for operating a home-session management function (H-SMF) in a wireless communication system, according to an embodiment, may comprise transmitting a first message requesting subscription data for a packet data unit (PDU) session to a unified data management (UDM), receiving, from the UDM, a second message including the subscription data and information about allowing routing of roaming traffic to an edge hosting environment (EHE) of a home network, and selecting a home-edge application server discovery function (H-EASDF) based on the second message.

Abstract: The present disclosure relates to a method and device for transmitting and receiving video content including three-dimensional (3D) data. The method of transmitting video content through a plurality of assets includes identifying whether content transmitted through an asset is a sub-picture; when the content transmitted through the asset is the sub-picture, generating sub-picture asset information comprising information about other sub-pictures constituting a composition picture together with the sub-picture; and transmitting the sub-picture asset information and the content.

Abstract: A method and an apparatus for transmitting video-based point cloud contents (VPCC) data by a server are provided. The method includes generating moving picture experts group (MPEG) media transport protocol (MMTP) packets including at least one asset for the VPCC data, generating a signaling message including an asset group message about the at least one asset, and transmitting the MMTP packets and the signaling message to a client.

Abstract: The present disclosure relates to a communication apparatus and method for supporting a forward error correction scheme in a communication system. To this end, by means of a generation mode among a plurality of generation modes (ssbg_mode #0, #1, #2), a source symbol block having a plurality of source symbols is generated by using a source packet block having a plurality of source packets, and a repair symbol block for the generated source symbol block is generated by means of a forward error correction (FEC) scheme among a plurality of FEC schemes (FEC payload ID mode 0, FEC payload ID mode 1). A first FEC scheme (FEC payload ID mode 1) is applied to generate the repair symbol block, and in response to an occurrence of a discontinuity in packet sequence numbers, a repair packet may be generated to include length repair data and a repair FEC payload identifier (ID).
