A method, performed by a network entity, of performing time sensitive communication (TSC) includes: establishing a first protocol data unit (PDU) session with a first user equipment (UE) and a second PDU session for a second UE; receiving, from the first UE, an announce message obtained from a first time sensitive network (TSN) node; configuring, based on the announce message, a port state of the network entity; and transmitting, to the second UE or a second TSN node, the announce message.
