Terminal Handover Cell Selection Using Measurement Results
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cell handover methods in communication technologies often result in terminals being handed over to unsuitable cells, leading to inefficiencies in the handover process due to limited selection of target cells.
Innovation Solution
A method and apparatus that increase the number of cells considered for handover by determining a target cell based on measurement results and preset values, allowing for a more suitable cell to be selected for handover, including the use of beam quality and trigger thresholds to identify suitable cells.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the terminal reports measurement results based on trigger conditions, then the handover process can be automated, but the terminal may be handed over to unsuitable cells due to limited cell selection
Solution Approach 1:
The terminal performs preliminary actions by not only reporting the first cell that triggers the condition but also proactively determining and reporting measurement results of N measured cells (where N≥1) in advance. This allows the network device to have multiple candidate cells ready before handover decision, improving the reliability of target cell selection while maintaining automated handover.
2Productivity
If only the first triggering cell is reported, then the reporting process is simple and fast, but the network device has limited options for selecting a suitable target cell
Solution Approach 1:
The terminal performs partial additional action by determining measurement results of N measured cells (where N≥1) in addition to the first triggering cell. This excessive action of reporting more cells than the minimum single triggering cell provides the network device with more selection options and adaptability, while still maintaining relatively efficient handover processing.
3Measurement precision
If the terminal determines target cell based on multiple measured cells, then the cell selection quality improves, but the processing complexity increases
Solution Approach 1:
The terminal performs self-service by autonomously determining measurement results of N measured cells and identifying target cells based on preset values without requiring additional network device intervention. This self-service approach improves cell quality assessment precision while the terminal manages its own processing complexity through autonomous operation.

AI summary
Embodiments of this application provide a communications method and apparatus. The method includes: determining a target cell based on measurement results of N measured cells and a preset value when there is a first cell satisfying a report trigger condition; and sending a measurement result of the target cell to a base station. Based on the foregoing technical solution, the terminal may not only send the measurement result of the cell satisfying the trigger condition to the base station, but also send a measurement result of another cell to the base station. In this way, a quantity of cells that can be selected during determining of handover can be increased, to help the base station select a suitable cell for the terminal.
