Translator Time Synchronization Fault Handling in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Time synchronization faults occur in translators within 5G networks, leading to incorrect time synchronization and errors in time transfer to TSN devices, as translators may not be synchronized with the 5G grandmaster clock, resulting in inaccurate transmission delays and incorrect time information.
Innovation Solution
A method where a translator that is not synchronized with a clock source in a network stops communicating time information with other translators, preventing the propagation of incorrect time synchronization, and a configuration device manages port states to ensure accurate time synchronization by setting slave or master states for translators based on synchronization status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a translator continues to communicate time information with other translators when synchronization fails, then the translator can maintain communication functionality, but incorrect time information propagates through the network causing synchronization errors
Solution Approach 1:
The translator detects synchronization failure with the clock source and proactively stops communicating time information with other translators before incorrect time can propagate. This preliminary action prevents the harmful effect of synchronization errors spreading through the network, resolving the contradiction by prioritizing accuracy over communication continuity.
Solution Approach 2:
The faulty translator is extracted from the time synchronization communication chain by stopping its transmission and reception of time information. This isolates the synchronization failure to a single node, preventing it from affecting other translators and TSN devices, thus maintaining overall network reliability while containing the communication disruption.
2Reliability
If the translator stops communicating time information when synchronization fails, then propagation of incorrect time is prevented, but communication functionality is disrupted
Solution Approach 1:
The translator continuously monitors its synchronization status with the clock source and uses this feedback to control its communication behavior. When synchronization succeeds, normal time information communication occurs; when it fails, communication is automatically stopped. This feedback mechanism dynamically adjusts operation to maintain reliability while minimizing disruption to communication functionality.
3Productivity
If translators continue to calculate and transmit time information during synchronization faults, then communication remains active, but transmission delay calculations become inaccurate
Solution Approach 1:
The translator detects synchronization failure and preemptively stops calculating and transmitting time information, including transmission delays, before inaccurate values can be generated or propagated. This prevents the harmful effect of precision errors in time measurement and transmission delay calculation from affecting the network.

AI summary
This application discloses a time synchronization fault processing method, apparatus, and system, and belongs to the communication field. The method includes: When time of a first translator in a first network is not synchronized with a clock source in the first network, the first translator stops communicating time information with at least one other translator in the first network than the first translator, where the time information is used for obtaining time synchronized with a clock source in a second network.
