Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If home routing approach is used to route data traffic from visited mobile communication network to home mobile communication network, then data traffic can be routed through established operator agreements, but communication path becomes long causing latency and dissatisfaction
Solution Approach 1:
The patent segments the routing decision into two parts: detection of private network status and selection of appropriate network node. This allows the system to choose between home routing and local breakout based on specific conditions, optimizing both reliability and latency for different scenarios
Solution Approach 2:
The patent implements dynamic routing selection by detecting whether the terminal device is served by a private network and adjusting the routing path accordingly. The system can switch between home routing and local breakout dynamically based on real-time network conditions and private network detection results
2Loss of time
If local breakout approach is used to route data traffic directly from visited mobile communication network to data network, then communication latency is reduced, but more sophisticated routing solutions and detection mechanisms are required
Solution Approach 1:
The patent performs preliminary detection of private network status before establishing the data traffic path. By detecting whether the terminal device is served by a private network in advance, the system can pre-determine the appropriate routing mode (home routing or local breakout), simplifying the overall control complexity
Solution Approach 2:
The patent uses feedback from network detection results to adjust routing decisions. The control system continuously monitors private network status and technical parameters, using this feedback to select appropriate network nodes and routing modes, thereby managing complexity through intelligent adaptation
3Productivity
If sophisticated local breakout policy rules are implemented to manage routing parameters, then data traffic routing can be optimized, but device complexity and detection requirements increase
Solution Approach 1:
The patent creates a universal detection mechanism that can identify private networks through multiple indicators (network identifiers, location information, technical parameters). This multi-functional detection approach improves data routing efficiency while managing complexity through a unified detection framework that handles various network types and scenarios
