Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If communication distribution control is performed from the base station apparatus to the terminal apparatus, then the terminal apparatus can use an appropriate wireless system, but terminal apparatuses that do not support such control cannot utilize this benefit
Solution Approach 1:
The invention introduces a relay station apparatus as an intermediary that performs communication distribution control. The relay station acquires quality information between the terminal apparatus and base station apparatuses, determines appropriate wireless systems, and notifies the terminal apparatus of the determined data transmission method. This resolves the contradiction by enabling distribution control benefits for all terminal apparatuses regardless of their native support capabilities.
2Reliability
If detailed communication distribution control is implemented, then communication quality can be maintained, but the system complexity increases due to additional control mechanisms
Solution Approach 1:
The relay station apparatus serves as a mediator that centralizes the distribution control functionality. It acquires quality information, determines appropriate communication paths, and manages the complexity of controlling multiple wireless systems. This approach maintains communication quality while containing system complexity within the relay station rather than distributing it across all terminal apparatuses.
Solution Approach 2:
The terminal apparatus is provided with information about the determined data transmission method through the relay station, enabling it to autonomously select and use the appropriate wireless system without requiring complex native distribution control capabilities. This self-service approach maintains reliability while reducing the complexity burden on terminal apparatuses.
3Adaptability or versatility
If communication distribution control is performed on terminal apparatuses, then appropriate wireless system selection is enabled, but terminal apparatuses without support for this control cannot benefit
Solution Approach 1:
The relay station apparatus acts as an intermediary that performs the complex distribution control operations and communicates the results to terminal apparatuses. This allows terminal apparatuses to benefit from appropriate wireless system selection without needing to implement or understand the complex control mechanisms themselves, maintaining ease of operation while enabling adaptability.
Solution Approach 2:
The terminal apparatus receives notification of the determined data transmission method from the relay station and autonomously applies it to communicate using the appropriate wireless system. This self-service mechanism enables wireless system selection capability while keeping the terminal apparatus operation simple, as it only needs to follow the provided instructions without implementing complex control logic.
