Multi-Path Data Transmission for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data transmission methods between terminals and network-side devices rely solely on single-path processing, leading to interruptions in data reception and transmission upon radio link failures, which disrupts service continuity.
Innovation Solution
Implementing a multi-path data transmission method that includes both direct and indirect paths between a terminal and a network-side device, allowing the terminal to suspend data transmission through a failed path and resume once the link is restored.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single-path data transmission method is used, then the transmission path is simple, but data transmission interruption occurs when radio link failure is detected
Solution Approach 1:
The transmission path is segmented into multiple independent paths (direct path and indirect path via relay node). Each path can operate independently, so when one path fails due to radio link failure, the other path can continue to transmit data, thereby avoiding transmission interruption and improving service continuity.
Solution Approach 2:
The patent introduces a spatial dimension to the transmission path by utilizing a relay node to create an indirect path. This adds a dimensional layer to the transmission architecture, allowing data to be transmitted through multiple spatial routes (direct and via relay), which provides redundancy and improves reliability without causing complete transmission failure when one path is blocked.
2Reliability
If a multi-path data transmission method is used, then data transmission interruption is reduced, but the transmission path becomes more complex
Solution Approach 1:
The patent implements dynamic path selection and switching mechanisms. The terminal can dynamically detect radio link failures and switch between direct and indirect paths based on real-time network conditions. This dynamic adaptability allows the system to maintain data transmission continuity while managing the complexity of multiple paths through intelligent control rather than static configuration.
Solution Approach 2:
A relay node is introduced as an intermediary element in the indirect path. This intermediary simplifies the overall system architecture by providing a dedicated intermediate point for data routing. The relay node handles the complexity of indirect transmission, allowing the terminal to manage multi-path complexity more effectively through a structured intermediary rather than direct peer-to-peer complex routing.
3Productivity
If direct path is used for data transmission, then transmission speed is high, but transmission fails when radio link failure occurs
Solution Approach 1:
The patent changes the transmission parameter from a single direct path to multiple paths with different characteristics. The direct path provides high speed when available, while the indirect path via relay node provides reliability when the direct path fails. The system dynamically adjusts which path to use based on real-time radio link conditions, optimizing both speed and reliability through parameter change rather than fixed configuration.
Data Source
AI summary
A data transmission method is disclosed. The method includes: transmitting, by a first terminal, data with a network-side device through a multi path, wherein the multi path comprises a direct path through which the first terminal is in directly communication with the network-side device and/or an indirect path through which the first terminal is in communication with the network-side device via a second terminal; and suspending, in a case that the first terminal detects that a first path of the multi path fails, data transmission through the first path.
