Abstract
Provided is an operation method of a user plane function (UPF) apparatus in a wireless communication system, the operation method including: obtaining a subscription request message from either a TSN AF or a TSCTSF or both on the basis of an exposure service for a UPF event, the subscription request message including TSC management information; performing triggering for subscription to the UPF event on the basis of the TSC management information; and providing a notification message to either the TSN AF or the TSCTSF or both, the notification message including the TSC management information.
Claims8
An operation method of a user plane function (UPF) apparatus in a wireless communication system, the operation method comprising:
- obtaining a subscription request message from either a Time-Sensitive Networking Application Function (TSN AF) or a Time Sensitive Communication Time Synchronization Function (TSCTSF) or both on the basis of an exposure service for a UPF event, the subscription request message including Time-Sensitive Communication (TSC) management information;
- performing triggering for subscription to the UPF event on the basis of the TSC management information;
- providing a notification message to either the TSN AF or the TSCTSF or both, the notification message including the TSC management information;
- obtaining the TSC management information from the TSN AF or the TSCTSF;
- in response to the obtaining of the TSC management information, providing the TSN AF or the TSCTSF with a request message for subscription or unsubscription to the UPF event;
- and
- obtaining the notification message from the TSN AF or the TSCTSF.
A user plane function (UPF) apparatus in a wireless communication system, the UPF apparatus comprising:
- a transceiver;
- and
- at least one controller operably connected to the transceiver,
- wherein the at least one controller is configured to:
- obtain a subscription request message from either a Time-Sensitive Networking Application Function TSN AF or a Time Sensitive Communication Time Synchronization Function TSCTSF or both on the basis of an exposure service for a UPF event, the subscription request message including Time-Sensitive Communication TSC management information:
- perform triggering for subscription to the UPF event on the basis of the TSC management information;
- provide a notification message to either the TSN AF or the TSCTSF or both, the notification message including the TSC management information;
- obtain the TSC management information from the TSN AF or the TSCTSF;
- in response to the obtaining of the TSC management information, provide the TSN AF or the TSCTSF with a request message for subscription or unsubscription to the UPF event;
- and
- obtain the notification message from the TSN AF or the TSCTSF.
