Problems solved by technology

It is used to solve related technologies. After the 5G system is integrated into TSN, delay jitter may occur between TSN End Station and DS-TT, and between DS-TT and UE. This delay jitter will cause the TSCAI ( Time-sensitive communication auxiliary information) parameters are inaccurate, which affects the reliability of the industrial Internet

Embodiment Construction

[0069] 5G TSN technology will be widely used in industrial control, machine manufacturing, high-definition audio and video transmission and other fields. This technology has transformation requirements for terminals, base stations, transmission, and core networks. Terminals and User Plan Function (UPF) need to support TT (TSN Translator) function.

[0070] like Figure 1A As shown, 5GS (5G system) can be regarded as a Bridge (bridge), which consists of a port on the UPF (PSA) side, a user plane tunnel between the terminal UE and the UPF, and a port on the DS-TT side. The main network functions are described as follows:

[0071] CNC: Centralized Network Configuration, a centralized network configuration that can be applied to network devices (bridges).

[0072] CUC: Centralized User Configuration, centralized user configuration, can be applied to user equipment (End Station).

[0073] AMF: Access and Mobility Management Function, access and mobility management functions, regi...

Abstract

The invention discloses a delay jitter synchronization method and device and a storage medium, and relates to the technical field of communication. According to the specific implementation scheme, under the condition that a reporting condition is met, a terminal determines a delay jitter parameter and reports the delay jitter parameter to a network function entity NF. Therefore, the time delay jitter parameter can be determined, and the time delay jitter parameter can be reported to the network function entity NF under the condition that the reporting condition is satisfied, so that the accuracy of the TSCAI parameter can be ensured, and the reliability of the industrial Internet can be improved.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a time delay jitter synchronization method, device and storage medium. Background technique [0002] Currently, IEEE (Institute of Electrical and Electronics Engineers) 802.1 Time-Sensitive Networking (TSN) is becoming the standard Ethernet technology for Industry 4.0 converged networks. 5G and TSN can coexist in factory deployments and meet key requirements such as the flexibility of 5G and the extremely low latency of TSN. It is foreseeable that 5G TSN technology will be widely used in industrial control, machine manufacturing, high-definition audio and video transmission and other fields. [0003] However, after the 5G system is integrated into TSN, delay jitter may occur between the TSN End Station (time-sensitive network terminal) and DS-TT (device-side time-sensitive network translator), and between DS-TT and UE (terminal). , the delay jitter will ...
