Abstract
A 5G system operating as a Time Sensitive Network (TSN) bridge and a traffic transmission method are provided. The traffic transmission method includes receiving, by a User Plane Function (UPF), a traffic transmission type information from a Session Management Function (SMF); determining, by the UPF, whether a Time Sensitive Communication (TSC) traffic incoming the TSN bridge is a UE-UE TSC traffic based on the traffic transmission type information; and when it is determined that the TSC traffic incoming the TSN bridge is the UE-UE TSC traffic, performing, by the UPF, local switching between Protocol Data Unit (PDU) sessions for transmitting UE-UE TSC traffic.
