Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for collecting reception status information in radio communication systems, such as using dedicated measuring vehicles or mobile radio terminals, are costly and time-consuming, and fail to accurately recognize changes in reception status that affect system operation, leading to increased labor and maintenance expenses and potential service disruptions.
Innovation Solution
A system where mobile radio terminals monitor communication status and acquire reception status and positional information when predetermined conditions are met, sending this data to an information collecting server for immediate recording and analysis, allowing for instantaneous and accurate system adjustments with reduced man-hours and expenses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If dedicated measuring vehicles are used to collect reception status information, then measurement precision is improved, but device complexity and operating costs increase
Solution Approach 1:
The patent uses mobile radio terminals (cellular phones) as copies of dedicated measuring vehicles. These terminals already exist in users' possession and can perform measurement functions without requiring specialized equipment. The terminal's receiver measures reception status information from base stations, replicating the function of dedicated measuring vehicles while eliminating the need for specialized measurement equipment.
Solution Approach 2:
The patent makes mobile radio terminals serve multiple functions: they act as both communication devices for users and as measurement devices for collecting reception status information. The terminal's receiver is used for both normal communication reception and for measuring reception quality metrics, eliminating the need for separate dedicated measuring equipment.
2Measurement precision
If dedicated measuring teams operate measuring vehicles to collect reception status information, then measurement precision is improved, but loss of time and operating costs increase
Solution Approach 1:
The patent enables mobile radio terminals to automatically perform measurements and transmit data without requiring human operators. The terminal self-measures reception status information from base stations and automatically transmits the data to the management server, eliminating the need for measuring teams to manually operate vehicles and collect data.
Solution Approach 2:
The patent enables continuous collection of reception status information as users move through coverage areas. Unlike periodic manual measurements, the system continuously gathers data whenever terminals are in range, providing ongoing measurement coverage without interruption or manual intervention.
3Device complexity
If limited numbers of measuring vehicles are used to visit all coverages, then device complexity is reduced, but productivity decreases
Solution Approach 1:
The patent divides the measurement function across multiple independent mobile radio terminals distributed throughout the coverage area. Instead of using a few centralized measuring vehicles that must sequentially visit all areas, the measurement function is segmented and distributed to many user terminals, allowing parallel measurement across all coverage zones simultaneously.
Solution Approach 2:
The patent transitions from a centralized measurement approach (few vehicles covering all areas) to a distributed measurement approach (many terminals measuring locally). This adds a spatial dimension to the measurement system, utilizing the geographic distribution of users rather than concentrating measurement resources in a single location.
4Loss of energy
If general mobile radio terminals are used to measure reception status information, then operating costs are reduced, but measurement precision and reliability worsen
Solution Approach 1:
The patent implements feedback mechanisms where the management server receives measurement data from mobile terminals, processes it to identify coverage issues, and can send control signals to base stations for adjustment. This closed-loop feedback ensures that measurements are continuously refined and that the system responds to maintain optimal performance.
Solution Approach 2:
The patent replaces the mechanical system of dedicated measuring vehicles with electronic/software-based measurement capabilities embedded in mobile terminals. The measurement function is implemented through software in the terminal's receiver, eliminating the need for specialized hardware while maintaining measurement capability.

AI summary
There are disclosed a method of and a system for collecting information related to operation of a radio communication system inexpensively and easily. A mobile radio terminal monitors a communication status of user communication, and detects as a trigger when the communication status has satisfied a predetermined condition. When a trigger is detected, the mobile radio terminal acquires a reception status of a radio signal and the position of the mobile radio terminal. The mobile radio terminal sends measured information including the reception status and the position to an information collecting server. The information collecting server receives the measured information from the mobile radio terminal and records therein the measured information which has been received.
