Cell Measurement Reporting for Service-Quality-Aware Handover
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell handover processes in wireless communication often result in terminals being handed over to cells with high RSRP but poor service quality due to undiversified determining conditions, affecting user experience.
Innovation Solution
An electronic device adjusts communication quality parameters of neighboring cells based on predefined thresholds and coefficients to proactively suppress measurement reporting to cells with poor service quality, sending adjusted reports to the base station to guide informed handover decisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal performs measurement based on specified parameters (e.g., RSRP) and reports to the source base station, then the handover decision can be made efficiently, but the terminal may be handed over to a cell with high RSRP but poor service quality, affecting user experience
Solution Approach 1:
The terminal performs preliminary evaluation of service quality parameters (such as SINR, RSRQ, or throughput) before reporting measurement results. This preliminary action allows the terminal to identify and suppress cells with poor service quality in advance, preventing them from being selected for handover. The terminal adjusts the first parameter (e.g., RSRP) based on the second parameter (service quality indicator) before inclusion in the measurement report, thereby proactively guiding the base station's handover decision away from poor-quality cells.
Solution Approach 2:
The patent introduces an intermediary mechanism where the terminal acts as a mediator between the raw measurement data and the base station's handover decision. By adjusting the first parameter based on the second parameter (service quality indicator) before reporting, the terminal provides modified measurement information that reflects both signal strength and service quality. This intermediary processing ensures that the base station receives comprehensive information for making reliable handover decisions without directly implementing complex service quality evaluation at the base station side.
2Loss of information
If the terminal reports measurement results of all neighboring cells, then the base station has complete information for handover decisions, but the reporting overhead and processing complexity increase
Solution Approach 1:
The terminal extracts and suppresses measurement results from cells with poor service quality by adjusting their first parameters (e.g., RSRP) based on unfavorable second parameters (service quality indicators). This extraction process removes problematic cells from the measurement report or reduces their visibility, allowing the base station to focus on cells with better service quality. The terminal selectively processes only those cells that meet certain service quality criteria, reducing the overall complexity of measurement reporting while maintaining information quality.
Solution Approach 2:
The patent applies local quality differentiation by treating different neighboring cells differently based on their service quality characteristics. Instead of uniformly reporting all measurement results, the terminal adjusts the first parameter for each cell based on its specific second parameter value. Cells with good service quality retain their original first parameter values, while cells with poor service quality have their first parameters adjusted downward. This localized processing approach maintains necessary information diversity while reducing overall reporting complexity.

AI summary
This application provides a measurement reporting method and an electronic device. In this method, the electronic device obtains communication quality parameters of at least one neighboring cell. When detecting that a second parameter of a first cell is less than a first threshold, the electronic device lowers a first parameter of the first cell, and reports an adjusted first parameter of the first cell and an unadjusted first parameter of a second cell to a source base station, so that the first parameter for measurement reporting is suppressed on an electronic device side, thereby reducing a probability that the electronic device is handed over to a cell whose service quality is poor due to impact of the second parameter.
