RRC Connection Establishment for Seamless Relay Path Addition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in achieving high reliability and throughput in relay scenarios due to poor coverage, where existing methods for path switching in relay technologies do not effectively support the addition of indirect paths without disrupting direct paths, leading to inefficiencies in data transmission.
Innovation Solution
A method for establishing a multi-path connection by sending first information from a first terminal to a second terminal or network-side device through a second terminal to trigger the establishment of a radio resource control (RRC) connection, allowing for the addition of an indirect path while maintaining an existing direct path, using configuration information to ensure smooth transition and efficient data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single path (direct or indirect) is used for terminal communication, then the system complexity is low, but the communication reliability and throughput cannot meet the requirements for large amounts of network information
Solution Approach 1:
The patent segments the communication path into multiple independent paths (direct path and indirect path via relay terminal), allowing data to be transmitted simultaneously through different routes. This segmentation enables multi-path transmission which improves reliability and throughput while maintaining manageable system complexity through standardized path management procedures
2Productivity
If path switching is implemented in relay scenarios, then the communication performance can be improved, but the existing methods disrupt the direct path when adding indirect paths
Solution Approach 1:
The patent merges the direct path and indirect path into a unified multi-path transmission system where both paths coexist and operate simultaneously. The network device configures and manages multiple paths without disrupting existing connections, allowing seamless combination of direct and relayed transmission routes to improve productivity while maintaining path stability
Data Source
AI summary
A connection establishment method, a terminal, and a network-side device are provided. The connection establishment method includes: when there is a first path between a first terminal and a network-side device, sending, by the first terminal, first information to a second terminal or to the network-side device through a second terminal, where the first information is used to trigger establishment of a radio resource control (RRC) connection of the second terminal.
