Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the GAN system uses additional protocol layers to enable communication over WLAN, then communication versatility is improved, but overhead increases and bandwidth for payload traffic decreases
Solution Approach 1:
The protocol stack is segmented into two distinct parts: native network layers specific to each access network type (WLAN, cellular) and a common upper layer that handles application-specific functions. This segmentation allows each native layer to operate efficiently with minimal overhead while the common upper layer provides versatility across different networks.
Solution Approach 2:
The patent introduces an additional dimensional layering approach where protocol layers are organized not just by function but by network-specific versus common functionality. This dimensional organization allows the system to adapt to different network types by selecting appropriate native layers while maintaining a consistent upper layer interface.
2Extent of automation
If the GAN system forces data back through the carrier network, then network control is improved, but costs to the subscriber increase
Solution Approach 1:
The system dynamically selects which access network to use based on current conditions, allowing data to flow through the most efficient path available. This dynamic approach enables the system to maintain carrier network control when necessary while utilizing alternative networks like WLAN when they provide more cost-effective pathways.
Solution Approach 2:
The common upper layer acts as an intermediary between the application and the various native network layers, enabling intelligent routing decisions. This intermediary can direct traffic through different networks based on cost, availability, and performance considerations while maintaining overall network control.
3Adaptability or versatility
If the GAN system mimics a traditional base station controller, then compatibility with core mobile network is improved, but device complexity increases
Solution Approach 1:
Instead of fully implementing a complete base station controller simulation, the patent uses copying to replicate only the essential protocol functions needed for compatibility. The native network layers copy the necessary interface behaviors to work with existing core networks while avoiding the complexity of full BSC emulation.
