Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless relay systems in data communication networks require time-consuming and inefficient 360-degree wireless signal scans for attachment and reattachment to wireless access points, leading to potential connectivity losses and increased network resource load.
Innovation Solution
A system and method where a wireless relay performs a 360-degree wireless signal scan, reports results to a relay information server, determines reattachment attributes based on received attachment data, and optimizes subsequent scans to efficiently reattach to the best available access point, reducing the number of scans and load on network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless relay performs full 360-degree wireless signal scan before attaching to access point, then reliability of connection is improved, but loss of time increases and productivity decreases
Solution Approach 1:
The system performs a preliminary 360-degree wireless signal scan during initial attachment to establish baseline connectivity information. This preliminary action stores sector-level signal quality data that can be reused during reattachment scenarios, avoiding the need to repeat the full scan and thus reducing reattachment time while maintaining connection reliability.
Solution Approach 2:
The wireless signal scan is segmented into sector-specific measurements during initial attachment. Each sector's signal characteristics are independently recorded and stored. During reattachment, the relay can selectively re-evaluate only certain sectors based on mobility attributes rather than performing a complete 360-degree scan, thereby reducing time loss while preserving reliability.
2Reliability
If wireless relay performs another 360-degree wireless signal scan after losing connectivity, then reliability of reattachment is improved, but loss of time increases and productivity decreases
Solution Approach 1:
The scanning behavior dynamically adapts based on the reattachment scenario. When connectivity is lost, the system determines mobility attributes (such as whether the relay is stationary or mobile) and adjusts the scan scope accordingly. Stationary relays perform limited re-scanning of specific sectors, while mobile relays perform more comprehensive scans, optimizing network productivity while maintaining reattachment reliability.
Solution Approach 2:
The system changes scanning parameters (scan range, sector coverage, measurement depth) based on mobility attributes determined during reattachment. Instead of always performing full 360-degree scans, the relay adjusts scan parameters to match the specific reattachment context, improving network efficiency while preserving reliable reconnection.
3Measurement precision
If wireless relay performs repeated full scans during reattachment, then measurement precision of signal quality is improved, but use of energy increases and loss of time increases
Solution Approach 1:
Instead of performing complete repeated scans, the system applies partial action by re-measuring only specific sectors or frequency bands that are most relevant to the reattachment scenario. This partial measurement approach maintains sufficient signal quality measurement precision while significantly reducing energy consumption compared to repeated full scans.
Data Source
AI summary
A wireless relay controls wireless scanning in a wireless data communication network. The wireless relay performs a 360-degree wireless signal scan, and attaches to a source wireless access point responsive to the wireless signal scan. The wireless relay reports results from the wireless signal scan to a relay information server responsive to the attachment. The wireless relay receives attachment data from the relay information server responsive to the reporting. If the wireless relay loses connectivity to the source wireless access point, then the wireless relay determines reattachment attributes based on the attachment data, and performs another wireless signal scan based on the reattachment attributes.
