Wireless communication network in wireless communication system
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the disclosure, a method for operating a base station in a wireless communication system includes receiving, from a terminal, information on a residence time of the terminal and a transmission time of an uplink frame, determining a radio access network residence time based on the transmission time of the uplink frame, and transmitting the radio access network residence time and the residence time of the terminal to a user plane function (UPF).
1. A method performed by a device for a user plane function (UPF) in a 5 th generation system (5GS), the method comprising:
receiving, from a node of a time sensitive network (TSN), a message for synchronization;
generating an updated message for synchronization by including:
information for determining a residence time spent within the 5GS, and
information of a link delay from the node of TSN, wherein the link delay is added to a correction field of the message; and
transmitting, to a terminal in the 5GS, the updated message for synchronization.
2. A method performed by a terminal in a 5 th generation system (5GS), the method comprising:
receiving, from a device for a user plane function (UPF) in the 5GS, a message for synchronization including:
information for determining a residence time spent within the 5GS, and
information of a link delay from a node of a time sensitive network (TSN) in a correction field of the message;
identifying a residence time; and
transmitting, to a slave associated with the TSN, an updated message including the residence time added to the correction field of the updated message.
3. A terminal in a 5 th generation system (5GS), the terminal comprising:
a transceiver; and
at least one processor configured to:
receive, from a device for a user plane function (UPF) in the 5Gs, a message for synchronization including:
information for determining a residence time spent within the 5GS, and
information of a link delay from a node of a time sensitive network (TSN) in a correction field of the message;
identify a residence time; and
transmit, to a slave associated with the TSN, an updated message including the residence time added to the correction field of the updated message.
4. The method of claim 1 , wherein the message comprises a sync frame or a follow up frame.
5. The method of claim 1 , wherein the residence time is added to a correction field of the updated message.
6. The method of claim 1 , wherein the residence time is a difference between a time at which the message is received and a time at which the terminal receives the updated message.
7. The method of claim 1 , wherein the generating the updated message comprises adding the link delay to the correction field of the message.
8. The method of claim 2 , wherein the message comprises a sync frame or a follow up frame.
9. The method of claim 2 , wherein the link delay is added to the correction field of the message for synchronization.
10. The method of claim 2 , wherein the residence time is a difference between a time at which the device for the UPF receives a message from a node of the TSN and a time at which the terminal receives the message.
11. The method of claim 2 , wherein the identifying the residence time comprises adding the residence time to the correction field of the updated message.
12. The terminal of claim 3 , wherein the message comprises a sync frame or a follow up frame.
13. The terminal of claim 3 , wherein the link delay is added to the correction field of the message for synchronization.
14. The terminal of claim 3 , wherein the residence time is a difference between a time at which the device for the UPF receives a message from a node of the TSN and a time at which the terminal receives the message.
15. The terminal of claim 3 , wherein the at least one processor is further configured to add the residence time to the correction field of the updated message.
16. A device for a user plane function (UPF) in a 5th generation system (5GS), the device comprising:
