Mobile Network Selection via Position-Based Database Query
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face challenges in selecting the optimal network for data communication, especially for M2M devices globally distributed and moved, as they lack the necessary information about optimal networks based on location, leading to potential packet service issues and suboptimal communication rates.
Innovation Solution
An information processing apparatus and server system that detects the device's position, obtains communication network information, generates data communication-related information, and manages a database to correlate device positions with available mobile communication networks, enabling the selection of the most suitable network for data communication based on factors like throughput and packet loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic network selection is used, then device operation is simple, but data communication reliability deteriorates
Solution Approach 1:
The system performs preliminary actions by detecting device position and obtaining network information before data communication occurs. The information management server pre-acquires communication network information including packet service availability for each detected position, so that reliable network selection is already prepared when communication is needed, resolving the contradiction between simple operation and communication reliability.
2Reliability
If manual network configuration is performed, then communication reliability improves, but device complexity increases
Solution Approach 1:
The system implements self-service by automatically detecting device position, acquiring network information from the information management server, and selecting appropriate networks without user intervention. The mobile communication control unit autonomously performs network selection based on acquired information, eliminating manual configuration while maintaining reliability, thus resolving the contradiction between communication reliability and device complexity.
3Device complexity
If network information is not pre-acquired, then device complexity is reduced, but communication rate deteriorates
Solution Approach 1:
The information management server acts as an intermediary that handles the complexity of network information management externally. The server acquires and stores communication network information including throughput data for various positions, allowing the mobile device to simply query and use this pre-processed information, thus achieving high communication rates without increasing device complexity.
4Ease of operation
If packet service availability is not checked, then operation is simpler, but data communication reliability deteriorates
Solution Approach 1:
The system implements feedback by continuously detecting device position and using this information to query the information management server for network availability including packet service status. The mobile communication control unit receives feedback about which networks provide packet service at the current position and automatically selects appropriate networks, maintaining simple operation while ensuring packet service reliability through informed selection.
