Abstract: A wireless communication system is proposed. More particularly, an apparatus and a method for measuring and reporting performance monitoring data in a wireless communication system are proposed. Specifically, the operation method of a user plane function (UPF) in a wireless communication system includes receiving a QoS monitoring request from a session management function (SMF), wherein the QoS monitoring request may include monitoring of at least one of a data rate, a congestion level, a packet transmission count, a packet retransmission count, a packet retransmission ratio, a packet drop count, or a packet drop ratio.

Abstract: To conduct video conferencing between a plurality of distributed clients, a distributed controller receives a request from a first distributed client for a packet from a second distributed client selected as the main speaker, and a distributed media processor creates a switching entry for switching packets from the first and second distributed clients, in response to a request from the distributed controller. The distributed controller sends a packet transmission request to the second distributed client, and the distributed media processor receives a packet from the second distributed client and sends the received packet to the first distributed client based on the switching entry.

Abstract: An apparatus and method for directly exposing, by user plane function/network side-time sensitive networking translator (UPF/NW-TT), event result information to time sensitive networking (TSN) or time sensitive communication time synchronization function (TSCTSF) through service interface (Nupf) in wireless communication system. A method of operating event processing for TSN or TSC includes: when policy control function (PCF) performs TSC event subscription, receiving TSC management and control information for direct reporting notification of event result from TSN-application function or TSCTSF and transmitting the TSC management and control information to session management function (SMF); regenerating the TSC management and control information and transmitting the regenerated TSC management and control information to UPF/NW-TT through N4 interface; and receiving the TSC management and control information from SMF, and when a corresponding event occurs, transmitting the TSC management information including the event result to a target in the control information through SBI.
