Wireless Bearer Path Failure Recovery via Segmented Operation Sets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, especially in scenarios using both direct and indirect paths, existing technologies lack effective measures to manage and recover from failures in different communication paths, leading to potential network instability and service disruptions.
Innovation Solution
A method for a wireless communication node that configures both a direct and an indirect bearer associated with a Master Cell Group, where specific operation sets are executed based on the type of target bearer failure, including transmitting RRC messages, cell or relay selection, and path switching, to ensure reliable communication and rapid recovery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE uses both direct path and indirect path for communication, then reliability and throughput are improved, but device complexity and difficulty of managing path failures increase
Solution Approach 1:
The patent segments the communication paths into distinct direct path and indirect path bearers (first bearer and second bearer), each with independent failure detection and recovery mechanisms. This segmentation allows the system to manage each path separately, reducing the complexity of handling failures in a unified multi-path system while maintaining the reliability benefits of having multiple paths.
Solution Approach 2:
The patent implements dynamic path selection and switching mechanisms where the UE can adaptively switch between direct and indirect paths based on real-time failure detection. The system dynamically adjusts the active communication path without requiring complex manual configuration, allowing automatic recovery from failures while maintaining manageable system complexity through automated dynamic behavior.
2Reliability
If different operation sets are executed for different bearer types, then service quality and recovery effectiveness are improved, but processing complexity increases
Solution Approach 1:
The patent applies local quality by defining specific operation sets tailored to different bearer types (first bearer for direct path, second bearer for indirect path). Each bearer type has customized failure recovery operations appropriate to its characteristics, rather than applying a uniform recovery mechanism. This allows optimized service quality for each path type while managing complexity through localized, targeted processing rules.
3Stability of the object's composition
If rapid recovery from path failures is implemented, then communication stability is improved, but processing time and resource consumption increase
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple bearers (direct and indirect paths) before failures occur. The failure detection mechanisms and recovery operations are pre-established, allowing the system to rapidly switch to backup paths when failures are detected without requiring complex real-time analysis or configuration. This preliminary preparation enables fast recovery while minimizing processing time during actual failure events.
