Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If data passes through satellite for processing, then network service can be provided, but processing capability limitation causes high delays and reduced communication efficiency
Solution Approach 1:
The patent extracts the information processing function from the satellite and relocates it to peer protocol entities in terrestrial network devices. This allows the satellite to function purely as a transparent transmission medium, eliminating processing delays while maintaining network service provision capability.
Solution Approach 2:
The patent introduces peer protocol entities as intermediary components that handle information processing in the terrestrial network, acting as a mediator between the terminal device and the satellite. This intermediary approach enables complex processing to occur on the ground while the satellite maintains its simple relay function.
2Reliability
If satellite processes information, then network service is enabled, but device complexity increases due to limited satellite processing capability
Solution Approach 1:
The patent extracts the complex information processing functions from the satellite and places them in terrestrial peer protocol entities. This reduces satellite device complexity to a simple relay function while maintaining full network service capability through ground-based processing.
Solution Approach 2:
Instead of having the satellite perform complex processing functions, the patent inverts the architecture by having terrestrial devices perform processing and the satellite perform only simple transmission. This inversion resolves the contradiction between service capability and device complexity.
3Ease of operation
If multiple satellites correspond to one logical cell, then mobility management is improved, but coordination complexity increases
Solution Approach 1:
The patent uses peer protocol entities as intermediaries to manage the coordination between multiple satellites and one logical cell. These entities handle the complexity of satellite service coordination through standardized protocols, making mobility management easier while managing coordination complexity systematically.
