Solution Overview

Problem

In mobile communication systems, the collection of measurement data using radio terminals often results in a mix of important and unimportant data, leading to inefficient optimization efforts as operators may recognize non-issues as critical problems due to the inclusion of excessive unimportant data.

Innovation Solution

A method where a base station transmits configuration messages to radio terminals indicating areas where measurement data is unnecessary, allowing the terminals to exclude or stop data collection in those areas, thereby reducing unnecessary data reporting to the network.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If radio terminals report all measurement data to the network, then complete measurement information is collected, but the network receives excessive unimportant data leading to inappropriate optimization

Engineering Contradiction:

Improvemeasurement data completenessVSAvoidsignal-to-noise ratio of measurement data

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent extracts and removes unimportant measurement data from the reporting process by introducing the concept of 'measurement unnecessary area'. The base station identifies and designates specific areas where measurement data is not needed, and radio terminals exclude data from these areas before reporting. This extraction principle separates important measurement data from unimportant data, ensuring only valuable information is transmitted to the network, thereby maintaining data completeness while improving the signal-to-noise ratio.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by making the measurement reporting behavior spatially variable. Instead of uniformly reporting all measurement data across all areas, the system designates specific 'measurement unnecessary areas' where reporting is suppressed. The radio terminal's reporting behavior changes locally based on its position relative to these designated areas, allowing important data to be reported from critical regions while excluding unimportant data from non-critical regions.

Inventive Principle:

Principle #3Local quality

2Reliability

If radio terminals perform measurement in all areas, then comprehensive coverage is achieved, but processing burden and energy consumption increase

Engineering Contradiction:

Improvemeasurement coverageVSAvoidenergy consumption of radio terminal

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent extracts unnecessary measurement activities from the terminal's operation by designating 'measurement unnecessary areas'. When a radio terminal determines it is located within these designated areas, it stops performing measurements and excludes any data from these areas from reporting. This extraction of unnecessary measurement tasks reduces the terminal's processing burden and energy consumption while maintaining comprehensive coverage in important areas.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies partial action by having radio terminals perform measurement only in necessary areas rather than in all areas uniformly. The terminal adjusts its measurement activity level based on its location relative to the designated measurement unnecessary areas, performing full measurement in important regions and no measurement in non-critical regions, thereby optimizing energy consumption while maintaining adequate coverage.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If all measurement data is collected and reported, then no important data is missed, but network processing complexity and time increase

Engineering Contradiction:

Improvedata collection completenessVSAvoidnetwork optimization efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent extracts unimportant measurement data from the network processing stream by preventing its generation at the terminal side. Through the measurement unnecessary area designation mechanism, the system ensures that terminals do not collect or report data from areas where measurement is not needed. This extraction of unnecessary data processing tasks from the network reduces processing complexity and time, thereby improving optimization efficiency while maintaining completeness of important data collection.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A measurement collection method used in a mobile communication system, comprises: a base station includes unnecessary area information, which indicates a measurement unnecessary area requiring no measurement data, into a configuration message as one of a parameter, and transmits the configuration message to a radio terminal; and the radio terminal excludes measurement data, which corresponds to the measurement unnecessary area indicated by the unnecessary area information, from a report object to the network, or stops measurement in the measurement unnecessary area and reports measurement data including a measurement result, other than that in the measurement unnecessary area, to the network.
