Multi-path Communication Management for Remote Terminal Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies in Release 17 do not support simultaneous activation of multiple paths (direct and indirect) between a remote terminal equipment and a network device, nor do they provide a dynamic handover mechanism between these paths.
Innovation Solution
A multi-path processing method and apparatus that allow for the activation, deactivation, and handover of both direct and indirect paths by receiving indication information and processing it accordingly, enabling dynamic path management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single path (direct or indirect) is used for communication between remote terminal equipment and network device, then the communication system is simple to manage, but the reliability and data transmission rate are limited
Solution Approach 1:
The communication path is segmented into multiple independent paths (direct path and indirect path through relay UE), each capable of carrying user data separately. This segmentation allows the system to use multiple paths simultaneously for parallel data transmission, thereby improving reliability and throughput while maintaining manageable complexity through independent path control
Solution Approach 2:
The patent introduces dynamic activation and deactivation mechanisms for different communication paths based on real-time conditions. The network device can dynamically activate one or both paths (direct/indirect) according to signal quality, network load, and terminal requirements, enabling flexible adaptation without requiring permanent complex multi-path configuration
2Productivity
If multiple paths are activated simultaneously to improve data transmission rate, then the productivity increases, but the complexity of path activation and handover management increases
Solution Approach 1:
The patent merges the control of multiple paths at the network device level, where the network device consolidates activation and handover decisions for both direct and indirect paths. This centralized control approach allows simultaneous activation of multiple paths for improved productivity while simplifying management by centralizing the complexity at the network side rather than requiring complex terminal-side coordination
Solution Approach 2:
The system implements feedback mechanisms where the terminal equipment reports path status and quality information to the network device, which then uses this feedback to dynamically adjust path activation and handover decisions. This feedback loop enables intelligent path management that adapts to changing conditions, improving data transmission rate while keeping management complexity under control through automated decisions
3Adaptability or versatility
If dynamic handover between paths is implemented to adapt to changing network conditions, then the adaptability improves, but the complexity of handover processing increases
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple communication paths (direct and indirect) before actual data transmission begins. The network device prepares path parameters and activation configurations in advance, so when handover is needed, the terminal can quickly switch between pre-configured paths without complex real-time processing, thereby improving adaptability while reducing handover processing complexity
