Patent ID: 11937128
Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A user equipment (UE), comprising:
a processor;
a non-transitory computer-readable storage medium storing a program that is executable by the processor;
a receiver, configured to receive first latency information of a flow, wherein the first latency information indicates a first latency of transmitting the flow from a flow service provider in a time sensitive network (TSN) to a first communications device; and
a transmitter, configured to send information about the flow to a session management function (SMF) network element, wherein the information about the flow is used to determine a quality of service parameter corresponding to the flow;
wherein the receiver is further configured to receive the quality of service parameter corresponding to the flow from the SMF network element;
wherein the program includes instructions for:
determining a first target latency based on the quality of service parameter corresponding to the flow, wherein the first target latency is a latency of transmitting the flow between the UE and a user plane function (UPF) network element;
determining a third latency based on the first latency, the first target latency, and a second target latency, wherein the second target latency is a latency of transmitting the flow from a second communications device to a target network element that is in the TSN network and that is used as a next hop of the second communications device, and the third latency is a latency of transmitting the flow from the flow service provider to the target network element; and

wherein the transmitter is further configured to send third latency information, wherein the third latency information indicates the third latency.
