Standby Synchronization Priority in Redundant Communication Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing redundancy methods in wireless communication systems face challenges in balancing cost and time efficiency, with one-to-one redundancy increasing costs and N+M methods prolonging system startup times due to software installation and data copying.
Innovation Solution
A communication apparatus that determines the degree of impact on communication for each unit and prioritizes synchronization processing with a standby system for units with high impact, reducing the number of standby systems and minimizing downtime.

Engineering Contradiction Analysis
1Reliability
If one-to-one redundancy method is used, then system reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent applies local quality by differentiating the redundancy configuration based on the impact degree of each active system unit. Instead of uniform one-to-one redundancy, the system selectively applies standby units only to active units with high impact degrees, creating non-uniform local redundancy that optimizes both reliability and resource efficiency.
Solution Approach 2:
The patent segments the active system units into different groups based on their impact degrees. By dividing the system into high-impact and low-impact segments, the redundancy strategy can be tailored to each segment, applying full redundancy only where necessary and reducing or eliminating it elsewhere, thereby reducing overall device complexity.
2Device complexity
If N+M redundancy method is used, then device complexity is reduced, but loss of time increases
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing the impact degrees of all active system units in advance. This pre-assessment allows the system to quickly identify which units require standby coverage when failures occur, eliminating the need for time-consuming real-time analysis during failure recovery and thus reducing loss of time.
Solution Approach 2:
The system continuously monitors and updates the impact degrees of active units based on current system state and failure consequences. This feedback mechanism ensures that the redundancy allocation remains optimal even as system conditions change, allowing the system to adaptively adjust which units require standby support without manual intervention.
3Reliability
If redundancy units are increased, then reliability is improved, but loss of substance increases
Solution Approach 1:
The patent changes the parameter of redundancy allocation from a fixed uniform value to a dynamic value based on impact degree. By adjusting the redundancy parameter according to the calculated impact of each active unit, the system achieves optimal reliability with minimal resource consumption, avoiding the waste of maintaining standby units for low-impact components.
