CHO Parameter Adjustment via Terminal Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Conditional Hand Over (CHO) mechanism in wireless communications lacks an effective solution for reasonably configuring CHO parameters on the network side, leading to potential service disruptions and increased failure rates during high-frequency or high-speed user movements.
Innovation Solution
The proposed solution involves a method and apparatus where a terminal records relevant CHO information and reports it to the network side, allowing the network device to adjust CHO parameters based on this information, thereby ensuring more reasonable configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the existing CHO mechanism is used without parameter adjustment capability, then the HO process can be executed, but the CHO parameters cannot be reasonably configured leading to increased failure rates
Solution Approach 1:
The patent implements a feedback mechanism where the terminal device reports CHO execution information (including success/failure status and channel quality measurements) back to the network device. The network device uses this feedback to dynamically adjust CHO parameters such as threshold values and target cell selections, thereby improving HO success rates through continuous optimization based on actual performance data.
Solution Approach 2:
The patent transforms the static CHO parameter configuration into a dynamic adjustment process. Parameters that were previously fixed by the network are now dynamically modified based on real-time channel conditions and HO outcomes reported by the terminal, enabling the system to adapt to varying mobility scenarios and improve reliability.
2Reliability
If CHO parameters are configured statically without adjustment, then the configuration process is simple, but the configurations become unreasonable under varying mobility conditions
Solution Approach 1:
The terminal device collects CHO execution information including channel quality measurements and HO outcome status, then reports this data to the network device. This feedback loop enables the network to assess the rationality of current CHO parameters and make informed adjustments, improving configuration quality without requiring complex terminal-side processing.
3Productivity
If no CHO information reporting is implemented, then the system operation is simple, but the network side cannot adjust parameters to improve performance
Solution Approach 1:
The terminal device is pre-configured with CHO parameters and measurement requirements by the network. Before actual handover execution, the terminal prepares and stores relevant CHO information including measured channel quality and candidate cell data, enabling rapid reporting after HO events occur and facilitating timely parameter adjustments.
