Target Access Point Recommendation Using Velocity Vector
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless devices face challenges in efficiently switching between wireless access points during travel, leading to disruptions in wireless signaling and increased power consumption due to the need for frequent handovers, especially when approaching communication range limits or during access point maintenance.
Innovation Solution
A method for generating target access point recommendations based on the device's velocity vector and geolocation information, which anticipates future connections by selecting access points with the smallest angular position and suitable signaling range, thereby minimizing power consumption and maintaining continuous service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices perform frequent handovers between access points during travel, then connectivity is maintained, but power consumption increases and service disruptions occur
Solution Approach 1:
The system performs preliminary actions by determining the device's velocity vector and geolocation information to predict future access points before handover is needed. The target access point is identified in advance based on movement direction and signal strength projections, allowing the device to prepare for handover proactively rather than reactively, thus reducing unnecessary handovers and power consumption.
2Duration of action of moving object
If wireless devices switch access points at communication range limits, then service continuity is maintained, but handover disruptions increase
Solution Approach 1:
The system determines a target access point in advance by analyzing the device's velocity vector and current geolocation. By projecting future position based on movement direction and identifying access points along the trajectory, the system prepares handover information before the device reaches the current access point's range limit, enabling smoother transitions and reducing service disruption time.
3Measurement precision
If GPS is continuously used for geolocation tracking, then accurate target access point recommendation is achieved, but energy consumption increases
Solution Approach 1:
Instead of continuous GPS operation, the system uses periodic geolocation updates combined with velocity vector determination from movement patterns. The target access point recommendation is generated at specific intervals based on accumulated position data and movement direction, reducing GPS activation frequency while maintaining sufficient accuracy for predicting future access points along the device's trajectory.

AI summary
Recommending a target access point is contemplated. The target access point recommendation may be used to recommend device connection to an access point having capabilities sufficient to facilitate access to electronic services, such as but not necessarily limited to recommending connection of a wireless device to a cellular or Wi-Fi capable access point.
