Solution Overview

Problem

There is no known method for efficiently acquiring a geographical distribution of information related to roaming services in mobile communication networks, especially when a user's terminal is outside the service area of their contracted carrier.

Innovation Solution

A program and information processing apparatus that acquire position information, connection carrier identification, and communication environment details, generating log information that associates these elements to track roaming and communication carrier usage, allowing for the analysis of communication states and geographical distribution of roaming information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a terminal measures line speed manually, then communication environment information can be obtained, but the geographical distribution of roaming information cannot be efficiently acquired

Engineering Contradiction:

Improvecommunication environment measurementVSAvoidroaming information acquisition efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The terminal performs communication environment information acquisition in advance during normal operations, storing the data locally before it can be used for roaming analysis. This preliminary data collection enables efficient subsequent analysis of geographical distribution patterns without requiring dedicated measurement sessions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The terminal automatically acquires, stores, and manages its own communication environment information and position data without external intervention. This self-service approach enables the system to accumulate sufficient data for roaming analysis independently, improving overall acquisition efficiency.

Inventive Principle:

Principle #25Self-service

2Loss of information

If the terminal continuously monitors communication environment, then comprehensive data is collected, but power consumption increases

Engineering Contradiction:

Improvecommunication environment data completenessVSAvoidterminal power consumption

Core Design Contradiction:

Loss of informationVSUse of energy by moving object

Solution Approach 1:

Instead of continuous monitoring, the terminal acquires communication environment information at periodic intervals based on predetermined conditions such as time elapsed, position changes, or communication state transitions. This periodic approach maintains data completeness for roaming analysis while significantly reducing power consumption compared to continuous monitoring.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The terminal acquires communication environment information selectively based on predetermined conditions rather than continuously. By triggering measurements only when specific conditions are met (such as position changes or communication state transitions), the system obtains sufficient data for roaming analysis while minimizing unnecessary power consumption.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

To judge whether there is roaming, a computer is caused to perform a position information acquisition procedure to acquire position information of the computer, a connection carrier information acquisition procedure to acquire connection carrier identification information for identifying a communication carrier of a communication network to which the computer is connected at the position where the position information was acquired, and a log information generation procedure to generate log information in which the position information and the connection carrier identification information are associated with each other.
