Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different Radio Access Technologies (RATs) operate independently with their own data formats, then each technology can maintain its own optimization and performance, but seamless data transmission between RATs cannot be achieved
Solution Approach 1:
The patent introduces an aggregation adaptation layer function entity as an intermediary between LTE and 5G networks. This entity receives user plane data in the first format from the LTE network, converts it to the second format suitable for the 5G network, and forwards it to the 5G base station. This mediator approach enables seamless interoperability between different RATs while managing format conversion complexity in a centralized manner.
2Adaptability or versatility
If a format conversion function is added to enable interoperability between LTE and 5G, then data transmission between different RATs is enabled, but the base station structure becomes more complex
Solution Approach 1:
The patent segments the base station functionality into distinct entities: a user plane entity that handles LTE data reception, an aggregation adaptation layer function entity that performs format conversion, and an interface to the 5G base station. This segmentation allows each component to focus on specific tasks, making the overall complex system more manageable and maintainable while supporting multiple standards.
3Reliability
If user plane data is transmitted directly between LTE and 5G networks without conversion, then transmission speed is maintained, but compatibility issues arise due to different data formats
Solution Approach 1:
The aggregation adaptation layer function entity performs format conversion as a preliminary action before data transmission between different RATs. By converting the data format in advance at the source network side, the system ensures compatibility is established before transmission begins, avoiding compatibility issues during the actual data transfer process and enabling reliable communication between LTE and 5G networks.
