Cell Handover Measurement Reporting Using Service-Quality Suppression
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 actively adjusts communication quality parameters, such as RSRP and SINR/RSRQ, before reporting to the base station, suppressing measurement reports for cells with poor service quality and enhancing the handover decision-making process.
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
Solution Approach 1:
The patent changes the measurement parameters from single-parameter (RSRP only) to multi-parameter evaluation (RSRP combined with service quality indicators). The terminal now measures and reports both signal strength and service quality parameters, enabling the base station to make handover decisions based on comprehensive parameter sets rather than单一的signal strength, thus resolving the contradiction between efficient handover and reliable service quality
Solution Approach 2:
The patent introduces feedback mechanisms where the terminal measures service quality parameters of neighboring cells and feeds back this information to the base station. The base station then uses this feedback to adjust handover decisions, creating a closed-loop system that continuously optimizes handover based on actual service quality rather than relying solely on pre-configured RSRP thresholds, thereby improving both efficiency and reliability
2Ease of operation
If the base station uses a single determining condition (e.g., RSRP threshold) for handover decisions, then the handover process is simple and fast, but it cannot distinguish cells with high RSRP but poor service quality
Solution Approach 1:
The patent makes the handover decision system multi-functional by enabling it to evaluate both signal strength and service quality simultaneously. The base station is configured to use multiple determining conditions (RSRP threshold and service quality threshold) that work together universally to assess candidate cells, allowing a single handover decision mechanism to handle both simple signal-based handovers and complex quality-based handovers without requiring separate specialized systems
Solution Approach 2:
The patent segments the handover decision criteria into multiple independent evaluation dimensions (signal strength evaluation and service quality evaluation). Each dimension can be independently configured with its own thresholds and weights, allowing the system to flexibly combine multiple segmentation criteria to make comprehensive handover decisions, thus maintaining simplicity while improving adaptability
Data Source
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.
