Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If flight path is adjusted based on estimation, then communication resource allocation can be optimized, but communication continuity cannot be guaranteed when estimation differs from actual situation
Solution Approach 1:
The patent applies preliminary action by requesting radio resources in advance based on flight path information before the mobile terminal actually needs them. The control apparatus sends a first request message to the core network node with flight path information, enabling the network to allocate resources proactively rather than reactively, ensuring resources are ready when needed and maintaining communication continuity.
Solution Approach 2:
The patent implements feedback by establishing a closed-loop communication system where the control apparatus monitors the mobile terminal's actual position and communication status, then adjusts resource allocation requests accordingly. The core network node receives feedback about the terminal's movement and communicates this to the radio station, enabling dynamic adjustment of resource allocation to match actual needs and maintain reliable communication.
2Measurement precision
If multiple core network nodes are involved in resource allocation, then resource allocation accuracy for moving terminals is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the resource allocation function across multiple specialized core network nodes. The control apparatus separates concerns by having the core network node handle resource allocation decisions while the radio station handles actual resource provisioning. This segmentation allows each node to focus on specific tasks, improving allocation accuracy through specialized processing while managing complexity through functional separation.
Solution Approach 2:
The patent uses an intermediary approach by introducing the control apparatus as a mediating entity between the mobile terminal and the core network. The control apparatus collects flight path information, determines resource requirements, and formulates request messages that are sent to the core network node. This intermediary simplifies the interaction by pre-processing information and presenting it in a standardized format, reducing the complexity burden on individual network nodes.
