Cell Handover Reporting Using Predicted Measurement Values
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell handover procedures in communication systems face handover exceptions due to improper parameter configuration in measurement events, which do not adapt to current channel conditions, leading to inefficiencies in measurement reporting and handover processes.
Innovation Solution
Implement measurement reporting evaluation based on predicted values of measurement quantities using a prediction model, allowing terminals to determine optimal handover candidates without immediate measurement, thereby reducing handover exceptions and accelerating the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If measurement reporting evaluation is performed based on actual measurement values, then measurement accuracy is ensured, but measurement reporting delay increases and handover efficiency decreases
Solution Approach 1:
The patent applies preliminary action by predicting measurement values at future time points before actual measurements are taken. The prediction model uses historical measurement data to estimate future measurement values, allowing the terminal to perform measurement reporting evaluation in advance without waiting for actual measurements at those time points, thereby reducing measurement reporting delay while maintaining acceptable accuracy
Solution Approach 2:
The patent uses copying by creating predicted measurement values as substitutes for actual measurement values. Instead of requiring real measurements at every time point, the system generates predicted copies of what measurements would be, allowing measurement reporting evaluation to proceed based on these predicted copies, thus reducing the time loss associated with waiting for actual measurements
2Ease of manufacture
If measurement parameters are configured according to experience, then configuration simplicity is maintained, but adaptability to current channel conditions deteriorates causing handover exceptions
Solution Approach 1:
The patent applies dynamics by transitioning from static experience-based parameter configuration to dynamic prediction-based evaluation. The measurement reporting evaluation is no longer based on fixed pre-configured parameters but adapts to current and predicted channel conditions through the prediction model, allowing the system to respond dynamically to changing channel conditions while reducing handover exceptions
Solution Approach 2:
The patent uses feedback by utilizing historical measurement values as input to the prediction model. The model learns from past measurement data and uses this feedback to improve future predictions, creating a closed-loop system where measurement history continuously informs and improves measurement reporting evaluation, enhancing adaptability without complicating configuration

AI summary
This application relates to the field of communication technologies, and discloses a communication method, apparatus, and system. The method includes: A terminal determines predicted values of first-type measurement quantities of a plurality of cells at at least one time point in a first time period, where the plurality of cells include a serving cell and a candidate cell; and if the predicted values of the first-type measurement quantities of the plurality of cells at the at least one time point satisfy a reporting condition, sends measurement report information to a network device. According to the foregoing method, the terminal may perform measurement reporting evaluation based on the predicted values of the first-type measurement quantities of the plurality of cells at the at least one time point. In this way, the terminal does not need to perform actual measurement at the at least one time point, so that a measurement reporting process can be accelerated, and this helps reduce a handover exception caused by improper parameter configuration corresponding to a measurement event.
