Wireless Access Network Device Version Management via Peer-to-Peer Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless access network devices face challenges in managing version updates due to complexity, version mismatches leading to functional failures, and increased network bandwidth consumption, particularly when managing multiple devices with varying configurations and objects.
Innovation Solution
A wireless access network device with controlling and storing means that compares version information tables and acquires update files from adjacent devices to synchronize versions, reducing the need for centralized updates and minimizing network bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If version updates are performed through centralized NMS to all wireless access network devices, then version consistency across the network is improved, but network bandwidth consumption increases and update time increases
Solution Approach 1:
The patent segments the centralized version distribution into localized peer-to-peer transfers. Instead of NMS updating all devices centrally, the update is segmented into local propagations where each device that receives an update becomes a source for its neighbors, dividing the bandwidth burden across multiple small transfers rather than one large centralized distribution
Solution Approach 2:
The patent implements preliminary action by having devices pre-fetch update files from adjacent devices before NMS-directed updates are required. The difference detection mechanism proactively identifies version gaps, and devices automatically acquire updates from neighbors in advance, reducing the need for frequent centralized bandwidth-intensive transfers
2Reliability
If all objects in wireless access network device are updated at once through bundle file, then version synchronization is improved, but file size increases and memory consumption increases
Solution Approach 1:
The patent extracts only the necessary update components from the bundle file. Instead of downloading complete bundle files containing all objects, the difference detection mechanism identifies exactly which objects need updating, and only those specific objects are transferred and applied, eliminating unnecessary file bloat
Solution Approach 2:
The patent applies partial action by updating only the subset of objects that differ between versions rather than performing a complete bundle update. The difference detection compares current object versions against target versions and triggers updates only for mismatched objects, performing exactly enough action to achieve synchronization without excess
3Measurement precision
If comprehensive version management is implemented for all objects, then version control accuracy is improved, but device complexity increases
Solution Approach 1:
The patent implements self-service through automated difference detection and peer-to-peer update acquisition. The device automatically compares its object versions against the load module information, identifies gaps, and fetches updates from adjacent devices without human intervention, maintaining high version control accuracy while automating the complexity rather than requiring manual management processes

AI summary
A wireless access network device includes controlling means that controls communication and storing means that stores first table information that includes version information of each object. The controlling means includes difference detecting means for comparing the first table information in the storing means and second table information that is stored in a load module of the controlling means and for detecting a difference between the first table information and the second table information, the second table information including version information of the each object that is to have its version updated, and acquiring means for acquiring an update file for an object that is to have its version updated from another adjacent wireless access network device when the difference detecting means has detected the difference.
