Donor Access Point Selection for Relay Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless networks face challenges in providing high-quality service to increasing numbers of devices due to latency overhead in backhaul connections that span multiple wireless links, leading to service degradation such as dropped packets.
Innovation Solution
Selecting a donor access point for a relay wireless device based on signal levels and backhaul connection type, using tracking area codes to determine compatible backhaul connections and reduce latency risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If relay wireless devices are used to improve coverage and service quality, then coverage area and service quality are improved, but latency overhead increases due to multiple wireless links in backhaul connections
Solution Approach 1:
The patent changes the selection criteria parameters for donor access points by introducing backhaul connection type as a key parameter. By evaluating and selecting donor access points based on their backhaul connection characteristics (wired vs. wireless), the system optimizes the balance between service quality and latency, resolving the technical contradiction.
2Area of stationary object
If backhaul connections span numerous communication links, then coverage area is extended, but service degradation occurs due to latency overhead
Solution Approach 1:
The patent introduces backhaul connection type as a critical selection parameter for donor access points. By changing the parameters used to evaluate donor candidates to include backhaul characteristics, the system can select access points that provide both extended coverage and maintained service quality, resolving the contradiction between coverage area and service quality.
3Area of stationary object
If multiple wireless links are used in backhaul connections, then network coverage is expanded, but packet loss increases due to latency overhead
Solution Approach 1:
The patent changes the donor selection parameters to include backhaul connection type evaluation. By selecting donor access points with appropriate backhaul characteristics (preferring wired connections or those with fewer wireless hops), the system reduces packet loss while maintaining expanded network coverage, resolving the technical contradiction.

AI summary
Exemplary embodiments described herein include systems, methods, and nodes for selecting a donor for a relay wireless device. Signal levels corresponding to signals received at a relay wireless device from a plurality of access points are determined. Signal information is received from the plurality of access points, wherein the signal information comprises a group identification for each access point. The signal information for the access points may then be compared to a donor criteria. And the access point corresponding to the greatest signal level that also comprises signal information that meets the donor criteria may be selected as the donor for the relay wireless device.
