Terminal Location Reporting to Reduce Redundant Signaling

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In mobile communication networks, terminals redundantly report location measurement data, leading to significant signaling overhead and latency due to repeated reporting of the same data, which is inefficient and resource-intensive.

Innovation Solution

The terminal determines a location-measurement-data report type based on various factors such as location accuracy, latency requirements, moving speed, and location information, selecting from multiple report types to minimize unnecessary data transmission and reduce latency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal reports location measurement data every time it acquires new data, then the location information is kept updated, but signaling overhead increases and resources are wasted due to redundant reporting

Engineering Contradiction:

Improvelocation information updateVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The patent changes the reporting parameter from fixed (reporting every time) to variable (reporting based on change threshold). The terminal compares newly acquired location measurement data with previously reported data and only reports when the change exceeds a predetermined threshold, thus adapting the reporting behavior to actual location changes.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

Instead of reporting all location measurement data unconditionally, the patent applies partial action by selectively reporting only when necessary (when location change exceeds threshold). This reduces the amount of reporting actions to exactly what is needed, avoiding excessive reporting of redundant data.

Inventive Principle:

Principle #16Partial or excessive action

2Measurement precision

If the terminal reports location measurement data frequently, then the location accuracy is maintained, but latency increases due to repeated reporting procedures

Engineering Contradiction:

Improvelocation accuracyVSAvoidlocation measurement latency

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent introduces a dynamic parameter (reporting threshold) that controls when reporting occurs. By comparing the change in location measurement data against this threshold, the system maintains location accuracy by reporting when significant changes occur, while reducing latency by avoiding repeated reporting of minor changes.

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If the terminal always reports location measurement data, then complete location information is provided to the network, but signaling resources are consumed inefficiently

Engineering Contradiction:

Improvelocation information completenessVSAvoidsignaling resource efficiency

Core Design Contradiction:

Loss of informationVSProductivity

Solution Approach 1:

The reporting behavior changes from static (always report) to dynamic (report based on threshold). This ensures location information completeness is maintained by reporting when actual location changes occur, while improving signaling resource efficiency by eliminating redundant reports of unchanged or minimally changed location data.

Inventive Principle:

Principle #35Parameter changes

AI summary

A method for reporting location measurement data includes: acquiring location measurement data; determining a location-measurement-data report type, report content indicated by different location-measurement-data report types being different; and reporting the location measurement data based on the determined location-measurement-data report type.
