Terminal Roaming Steering via Protocol Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal roaming methods in WLANs have a low success rate due to the lack of support for IEEE 802.11v and deauth protocols by all terminals, leading to frequent steering failures.
Innovation Solution
A system that includes a control node and access points to measure signal strength, determine roaming behavior features, and steer terminals to neighboring access points based on supported protocols and network conditions, ensuring successful roaming by identifying optimal target access points that meet the terminal's requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the AP uses IEEE 802.11v protocol and deauth protocol to steer the terminal to roam, then the terminal roaming process can be initiated, but the steering success rate is low because not all terminals support these protocols
Solution Approach 1:
The patent applies preliminary action by determining which steering protocols are supported by the terminal before actually performing the roaming steering operation. The AP or controller first queries or detects the terminal's protocol support capabilities, then selects an appropriate steering method based on this pre-acquired information. This ensures that the chosen steering protocol is compatible with the terminal, thereby improving the success rate and reliability of roaming steering.
2Reliability
If the AP attempts multiple times to steer the terminal using IEEE 802.11v protocol, then the roaming steering can be repeated, but the process becomes complex and time-consuming when all attempts fail
Solution Approach 1:
The patent applies dynamics by making the steering process adaptive and flexible based on real-time feedback. When a steering attempt fails, the system dynamically switches to a different steering protocol or method rather than repeating the same failed approach. This dynamic adjustment allows the system to try multiple different strategies (IEEE 802.11v, deauth, or other supported protocols) until roaming succeeds, improving reliability without requiring complex pre-planning for all possible failure scenarios.
Solution Approach 2:
The patent uses feedback mechanisms where the outcome of each steering attempt is monitored and used to determine the next action. When steering fails, the system receives feedback about the failure and adjusts its approach accordingly by selecting alternative protocols supported by the terminal. This feedback-driven approach simplifies the overall process compared to rigid multi-attempt schemes, as the system learns from each attempt and adapts its strategy.
3Productivity
If the AP steers the terminal without considering the terminal's supported protocols, then the steering process is simple, but the steering success rate is low due to protocol incompatibility
Solution Approach 1:
The patent applies self-service by enabling the terminal to actively provide information about its supported steering protocols to the AP or controller. Instead of requiring the AP to complexly query or guess which protocols the terminal supports, the terminal autonomously reports its capabilities through capability indication messages or protocol announcement mechanisms. This self-service approach maintains operational simplicity for the AP while ensuring high roaming success rate through accurate protocol matching.
