Claim 0:
1. A method for reporting a delay time of a mobile communication system to a time sensitive networking (TSN) server in a TSN application function device of a mobile communication system, the method comprising:
receiving, from a user equipment (UE) communicating with a first TNS node, a residence time based on a grand master (GM) clock of the mobile communication system;
receiving, from a user plane function (UPF) device communicating with a second TSN node, a packet delay budget (PDB) based on a clock of the mobile communication system, wherein the PDB is a transmission elapsed time of a message or a packet between the UE and the UPF;
receiving, from the UPF device, information on a difference between a GM clock of the mobile communication system and a TSN grand master (GM) clock;
calculating a first bridge delay using the residence time and the PDB;
converting the first bridge delay into a second bridge delay based on the difference information, wherein the second bridge delay is based on the TSN GM clock; and
transmitting, to the TSN server, bridge information including the second bridge delay.
