Terminal Measurement Reporting Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, terminals frequently report measurement results of multiple neighboring cells when these results meet a measurement event reporting condition, leading to a waste of signaling resources due to the existing measurement reporting mechanisms.
Innovation Solution
A measurement reporting method where a terminal receives configuration information including timer, height, and speed settings, adjusts reporting frequency based on these parameters, and only reports measurement results when specific conditions are met, such as a threshold of neighboring cells meeting the condition or a timer expiring, thereby reducing unnecessary signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the terminal reports measurement results of multiple neighboring cells whenever they meet the measurement event reporting condition, then the network can obtain comprehensive measurement information, but signaling resources are wasted due to frequent reporting
Solution Approach 1:
The patent changes the reporting trigger mechanism from event-based to parameter-based (threshold-based). The terminal compares the quantity of neighboring cells meeting the measurement event condition against a configured threshold. Only when this quantity reaches or exceeds the threshold does the terminal trigger a measurement report. This parameter-based control reduces unnecessary reporting while ensuring the network receives sufficient measurement information for handover decisions.
2Speed
If the terminal reports every time a new neighboring cell meets the measurement event condition, then the network receives timely updates, but reporting frequency increases causing resource waste
Solution Approach 1:
The patent introduces a threshold parameter to control reporting frequency. Instead of reporting immediately when any new cell meets the condition, the terminal accumulates measurements and only reports when the threshold is reached. This balances timeliness (reporting when sufficient information is available) with resource efficiency (avoiding excessive reporting).
Solution Approach 2:
The patent uses a threshold mechanism that allows partial reporting - not every qualifying cell triggers a report, but enough cells (reaching the threshold) provide sufficient information for network decisions. This partial action approach avoids excessive reporting while maintaining adequate information flow.

AI summary
Embodiments of this application relate to the communications field, and disclose a measurement reporting method and an apparatus, to resolve a waste of signaling resources that is caused by reporting measurement results of a plurality of neighboring cells by a terminal when the terminal learns, through measurement, that the measurement results of the plurality of neighboring cells meet a measurement event reporting condition. A specific solution is as follows: The terminal receives measurement configuration information sent by a network device, where the measurement configuration information is used by the terminal to report a neighboring cell measurement result, and the measurement configuration information includes at least one of timer configuration information, height configuration information, and speed configuration information; and the terminal measures a neighboring cell, and reports a measurement report to the network device according to the measurement configuration information, where the measurement report includes a measurement result of at least one neighboring cell, the measurement result of the at least one neighboring cell meets a first condition, and the first condition is a measurement event entering condition or a measurement event leaving condition. The embodiments of this application are used to report a measurement event.
