Communication Log Analysis for Wide-Area Network State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for measuring line speed in mobile communication networks only provide snapshots of communication states at specific times and locations, failing to capture actual usage scenarios over wide areas and changes in communication states over time.
Innovation Solution
An information processing apparatus and method that acquires log information from communication terminals, including position and communication environment data, to generate statistical information about communication environments, allowing for classification and analysis of communication states across various positions and time periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If line speed measurement is performed at specific time and place, then measurement simplicity is improved, but comprehensiveness of communication state analysis deteriorates
Solution Approach 1:
The patent segments the measurement process into multiple measurement points distributed across different locations and time periods. Each measurement point collects local communication state data, which is then aggregated to form comprehensive statistical information about the entire communication environment, resolving the contradiction between simple single-point measurement and comprehensive multi-point analysis.
Solution Approach 2:
The patent uses communication terminals to automatically generate and transmit log information copies of communication state data from multiple positions and time points. These copies are aggregated by the information processing apparatus to create a comprehensive statistical picture without requiring complex manual measurement procedures at each location.
2Device complexity
If measurement is performed at single position, then device complexity is reduced, but spatial coverage of communication analysis deteriorates
Solution Approach 1:
The patent makes communication terminals perform multiple functions: they not only communicate normally but also automatically generate log information, record position data, and transmit measurement results to the information processing apparatus. This multi-functionality allows a single terminal type to contribute to comprehensive spatial coverage without increasing device complexity.
Solution Approach 2:
The patent introduces log information as an intermediary data structure that bridges the communication terminal and the information processing apparatus. This intermediary carries position information, communication state data, and timing information, enabling the system to aggregate data from multiple spatial locations without requiring complex direct connections between all measurement points.
3Speed
If communication state is measured at fixed time point, then measurement speed is improved, but temporal coverage of communication changes deteriorates
Solution Approach 1:
The patent implements continuous measurement by having communication terminals automatically generate and transmit log information at multiple time points. The information processing apparatus continuously aggregates this data to track communication state changes over time, maintaining both measurement speed through automated processing and temporal coverage through repeated measurements at different moments.

AI summary
In order to know a communication state similar to an actual usage state of a user over a wide area, provided is an information processing apparatus that sends and receives information to and from a communication terminal via a network. The information processing apparatus includes a log information acquiring section that acquires, from the communication terminal, one or more pieces of log information in which position information identifying each of one or more positions and information relating to a communication environment of the communication terminal at each of the one or more positions are associated with each other; and a statistical information generating section that generates statistical information relating to the communication environment at a position, based on the one or more pieces of log information.
