Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication relay systems face challenges in satisfying delay requirements when transmitting radio signal data using both CPRI and Ethernet communication methods, as existing methods struggle to accurately reflect delay parameters across different networks.
Innovation Solution
The communication relay system employs a CPRI-Ethernet converting device that acquires and reflects delay parameters from the CPRI network onto the eCPRI network, using map information to adjust delay parameters and ensure accurate transmission, even with multiple conversions between networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If radio signal data is transmitted using both CPRI and Ethernet communication methods simultaneously, then the system can support legacy devices and new devices, but it becomes difficult to satisfy required delay conditions across different communication methods
Solution Approach 1:
The patent introduces a delay parameter reflection mechanism that acts as an intermediary between CPRI and Ethernet networks. The converting device measures delay parameters in the CPRI network and reflects them to the Ethernet network side, enabling coordinated delay management across different communication methods while maintaining compatibility with both legacy CPRI devices and new Ethernet devices
Solution Approach 2:
The system implements a feedback loop where delay parameters are measured in the CPRI network, reflected to the Ethernet network, and used to adjust transmission parameters. This feedback mechanism ensures that delay conditions are satisfied across both communication methods by continuously monitoring and adapting to actual network conditions
2Device complexity
If delay parameters are not accurately reflected across network conversions, then the system can operate with simpler parameter management, but radio signal data transmission fails to meet required delay conditions
Solution Approach 1:
The converting device performs preliminary measurement of delay parameters in the CPRI network before data transmission occurs. By measuring and reflecting delay parameters in advance, the system prepares the necessary information for proper delay management in the Ethernet network, ensuring delay requirements are met without adding complex real-time adjustment mechanisms
