1. A method of operating event processing for time sensitive networking (TSN) or time sensitive communication (TSC) in a wireless communication system, the method comprising:
when a policy control function (PCF) performs a TSC event subscription, transmitting TSC management information and control information to a session management function (SMF) using a Npcf_SMPolicy service interface, wherein the control information is required for direct reporting notification of an event result from a user plane function/network side-TSN translator (UPF/NW-TT) to a TSC time synchronization function (TSCTSF);
regenerating, by the SMF, the TSC management information and the control information received from the PCF and transmitting the regenerated TSC management information and the control information to the UPF/NW-TT through an N4 interface; and
receiving, by the UPF/NW-TT, the TSC management information and the control information received from the SMF, and when a corresponding event occurs, directly transmitting the TSC management information including the event result to a notification target address using a Nupf_EventExposure_Notify service interface,
wherein the control information includes a notification target address and a notification correlation identifier,
wherein the notification target address includes an address of the TSCTSF to which the UPF/NW-TT transmits the result of the corresponding event, and
wherein the notification correlation identifier is included in the Nupf_EventExposure_Notify service interface.
