Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 7:
8. A time sensitive networking (TSN) application function (AF) device for reporting a delay time of a mobile communication system to a TSN server, the TSN application function device comprising:
a network interface configured to communicate with nodes of the mobile communication system and a TSN node;
a memory configured to store a delay time of data of the TSN node; and
at least one processor is configured to:
receive, from an UE communicating with a first TNS node through the network interface, a residence time based on a grand master (GM) clock of the mobile communication system,
receive, from a user plane function (UPF) device communicating with a second TSN node through the network interface, 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,
receive, from the UPF device, information on a difference between the GM clock of the mobile communication system and a TSN grand master (GM) clock,
calculate a first bridge delay using the residence time and the PDB,
convert 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
transmit, to the TSN server, bridge information including the second bridge delay.
