Wireless Base Station Belonging Information Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless meshed networks, existing methods for managing belonging information between base stations lead to inefficient traffic generation and prolonged synchronization times, especially when dealing with unsynchronized differences and updates from multiple base stations, resulting in potential communication disconnections and network bandwidth compression.
Innovation Solution
A wireless base station system that includes a management table with new/old judgment information for updates, transmitting only the updated portions and judgment information during updates, and synchronizing the belonging information management table based on received notification information from other base stations, reducing unnecessary traffic and enabling prompt synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If LAB is notified every predetermined constant frequency, then synchronization of belonging information is maintained, but communication disconnection time increases and synchronization efficiency deteriorates
Solution Approach 1:
The patent implements periodic notification of LAB (Local Association Base) information at constant intervals between base stations. This periodic action ensures that belonging information is synchronized across the network at regular time points, maintaining reliability while controlling the frequency of communications to avoid excessive traffic.
Solution Approach 2:
The patent employs a feedback mechanism where base stations notify each other of changes in LAB information. When a base station detects that its LAB information has changed, it notifies other base stations, which then update their local copies. This feedback-driven approach ensures synchronization only when necessary, reducing unnecessary traffic while maintaining up-to-date information.
2Loss of time
If transmission frequency of LAB message is shortened to reduce communication disconnection time, then synchronization speed improves, but unnecessary traffic increases and network bandwidth is compressed
Solution Approach 1:
The patent extracts and transmits only the essential LAB information (belonging information of terminals) between base stations, rather than transmitting complete data sets. This extraction principle reduces the volume of transmitted data while maintaining the critical synchronization functionality, thereby reducing unnecessary traffic.
Solution Approach 2:
The patent implements partial notification by sending LAB information changes only when necessary, rather than continuously transmitting all information. This partial action approach maintains synchronization effectiveness while significantly reducing the overall traffic volume compared to full-frequency transmission.
3Quantity of substance
If checksum diffusion mode is used to reduce traffic, then bandwidth consumption decreases, but synchronization time increases due to waiting for next notification frequency
Solution Approach 1:
The patent uses LAB (Local Association Base) information as an intermediary that carries essential belonging information between base stations. This intermediary mechanism allows for efficient transmission of critical synchronization data without requiring complete data exchange, reducing both traffic volume and synchronization delay compared to traditional checksum diffusion modes.
4Reliability
If all base stations notify large-sized LAB routinely each other, then complete information synchronization is achieved, but wireless band is consumed greatly resulting in poor efficiency
Solution Approach 1:
The patent extracts only the essential LAB information (belonging information of terminals) from the complete data set and transmits this extracted subset between base stations. This extraction principle maintains synchronization reliability by transmitting critical information while dramatically reducing the size of transmitted data, thereby reducing wireless band consumption and improving overall network efficiency.

AI summary
The present invention is to allow prompt and reliable synchronization of belonging information management table even in environments where there is a possibility of receiving update notification information from a plurality of wireless base stations, without needing unnecessarily large traffic for synchronization of belonging information management table. Wireless base station stores belonging information management table, to which belonging information of a terminal belonging to the base station is associated with, to new/old judgment information for judgment of new/old of update. Belonging information update unit performs update of belonging information including the new/old judgment information thereof. Further, upon receiving update notification information from other wireless base station, the belonging information update unit updates the belonging information management table based on the update notification information. The update notification information includes at least updated portion in the belonging information and new/old judgment information.
