Communication Apparatus Base Station Speed Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication apparatuses face instability in connections when selecting base stations based solely on the moving state of the device, leading to inappropriate selections and loss of communication due to increasing distance and reduced radio wave reach.
Innovation Solution
A communication apparatus that obtains and compares the moving speeds of both the device and the wireless base station, controlling connections based on a predetermined speed difference to ensure stable communication, thereby preventing connection to base stations with unstable communication states.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If base station selection is based solely on the moving state of the communication apparatus, then the selection process is simple, but connection stability deteriorates when the base station is also moving
Solution Approach 1:
The patent changes the selection parameter from only considering the communication apparatus's moving state to considering both the communication apparatus's moving state and the base station's moving state. This parameter expansion resolves the contradiction by maintaining simple selection logic while improving connection stability through more comprehensive information consideration.
2Ease of operation
If connection is made to a base station in the moving direction of the communication apparatus, then initial connection is established, but communication is lost soon due to increasing distance
Solution Approach 1:
The patent performs preliminary action by obtaining and analyzing the base station's moving state information before making the connection decision. This allows the communication apparatus to predict future distance changes and select a base station that will maintain stable communication, rather than simply connecting to the nearest or most accessible base station.
3Ease of operation
If the communication apparatus connects to a moving base station with opposite moving direction, then connection is established initially, but radio wave reach is reduced as distance increases
Solution Approach 1:
The patent converts the potentially harmful situation of connecting to a moving base station into a beneficial outcome by using the base station's moving state information to make intelligent selection decisions. Instead of avoiding all moving base stations, the system selectively connects to those whose movement patterns are compatible with maintaining stable communication, thus converting the potential harm of mobile base stations into a benefit.
