Handover Tendency Reporting for Reliable Node Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges with unsuccessful handovers due to deteriorated channel quality between user-side devices and target nodes, often triggered by unreasonable measurement reporting events, leading to potential handover failures.
Innovation Solution
A method for user-side devices to generate and report first auxiliary information, including handover tendency information, to network-side devices, which allows the network-side to determine optimal handover commands, thereby reducing failure probabilities by ensuring timely and successful handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement reporting events are triggered based on conventional criteria, then handover decisions can be made, but handover failures occur due to deteriorated channel quality between user-side devices and target nodes
Solution Approach 1:
The patent introduces auxiliary information (handover tendency information, prediction information, confidence levels) that is collected and reported before the actual handover decision is made. This preliminary action allows the network side to assess handover feasibility in advance, identify potential failures, and adjust handover parameters proactively, thereby improving handover success rates while maintaining manageable system complexity through structured information collection.
2Reliability
If handover commands are issued based on basic measurement reports, then handover process is simple, but handover failures occur due to insufficient information about handover tendency
Solution Approach 1:
The patent implements a feedback mechanism where user-side devices report auxiliary information including handover tendency information, prediction information, and confidence levels to the network side. This feedback loop provides the network with comprehensive information about handover feasibility, enabling informed handover decisions that account for channel quality trends, prediction accuracy, and uncertainty levels, thereby reducing handover failures.
3Measurement precision
If conventional measurement reporting is used, then reporting overhead is low, but inaccurate handover decisions are made due to lack of handover tendency information
Solution Approach 1:
The patent segments the measurement reporting into multiple structured components: basic measurement results, auxiliary information (handover tendency information), prediction information, and confidence levels. This segmentation organizes the reporting information systematically, allowing the network to process different types of information appropriately while maintaining manageable reporting overhead through efficient encoding and selective reporting based on confidence thresholds.
