Base Station Switching Using GPS Location Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face issues with inaccurate base station switching due to reliance on signal intensity, leading to potential communication quality degradation and switching errors, especially when the switching threshold is set too low or when neighboring base stations have significantly higher signal strengths.
Innovation Solution
Implementing a method where a server end apparatus uses GPS location information from a mobile apparatus to determine the correct base station to switch to, predicting the mobile apparatus's movement direction and speed to accurately time the switch and avoid errors, and utilizing BS distribution data to identify the appropriate serving area and corresponding base station.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If signal intensity is used to determine base station switching, then the switching decision is simple to implement, but switching errors occur frequently and communication quality deteriorates
Solution Approach 1:
The patent changes the parameter used for switching decisions from signal intensity to GPS location information. By using location coordinates and comparing them with pre-stored base station coverage areas, the system achieves more accurate switching decisions without the errors associated with signal intensity-based methods.
2Speed
If a low switching threshold is set to enable frequent switching, then switching responsiveness improves, but communication quality severely deteriorates due to unnecessary switches
Solution Approach 1:
The system performs preliminary actions by pre-storing base station distribution data and coverage area information before switching is needed. When switching is required, the system quickly compares current GPS location with pre-stored data to determine the appropriate base station, achieving fast response without unnecessary switching.
3Measurement precision
If GPS location information is used to determine base station switching, then switching accuracy improves significantly, but device complexity increases due to GPS requirements
Solution Approach 1:
The patent introduces GPS location information as an intermediary parameter that bridges the mobile device and base station selection. Instead of directly measuring signal intensity and making complex decisions, the system uses GPS coordinates as a mediator to determine which base station covers the current location, simplifying the overall decision process while improving accuracy.

AI summary
A wireless communication system and a method for switching a base station (BS) thereof are provided. In the present invention, a globe positioning system (GPS) of a mobile apparatus is capable of obtaining a location information about the mobile apparatus. On receiving the location information transmitted from the mobile apparatus, a server end apparatus switches to a corresponding BS of a serving area where the mobile apparatus is located so as to serve the mobile apparatus.
