1. A method of configuring time sensitive communications (TSC), comprising:
monitoring, by a user plane function (UPF), a source and destination of packets in a first protocol data unit (PDU) session of a first user equipment (UE), wherein the packets are communicated through a time sensitive network (TSN);
monitoring, by the UPF, a source and destination of packets in a second PDU session of a second UE, wherein the packets are communicated through the TSN;
assigning, by the UPF, port numbers to device side TSN translators (DS-TTs) served by the UPF;
sharing, by the UPF, the port numbers with a session management function (SMF);
pairing a first device side TSN translator (DS-TT) port of the first UE with a second DS-TT port of the second UE when the first PDU session and the second PDU session are served by a same UPF, wherein the pairing of the first DS-TT port and the second DS-TT port is based on the monitoring of the first and second PDU sessions and a source port number and a destination port number; and
when the first DS-TT and second DS-TT ports are paired, communicating the packets between the first UE and the second UE in a UE-UE communication without traversing the TSN.
