Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices perform frequent network scans to ensure availability across carrier networks, then network connectivity reliability is improved, but device energy consumption and network resource utilization deteriorate
Solution Approach 1:
The patent applies dynamics by making the rescan rate adjustable rather than fixed. The network rescan rate is dynamically modified based on roaming handover counts - when handover count exceeds a threshold, the rescan rate is increased to ensure connectivity; when below threshold, the rate is decreased to conserve energy. This dynamic adjustment resolves the contradiction between maintaining reliable connectivity and reducing energy consumption.
Solution Approach 2:
The patent changes the parameter of network rescan rate based on measured handover activity. By monitoring the roaming handover count and comparing it to a threshold, the system adjusts the rescan rate parameter upward or downward accordingly. This parameter change strategy allows the system to adapt scan frequency to actual roaming conditions, improving reliability when needed while reducing energy consumption during stable roaming.
2Reliability
If wireless devices perform frequent network scans to maintain connectivity during roaming, then network availability is improved, but network resource utilization and device battery life worsen
Solution Approach 1:
The system dynamically adjusts the network rescan rate based on actual roaming handover activity. When a device experiences frequent handovers (indicating unstable roaming), the rescan rate is increased to maintain network availability. When handovers are infrequent, the rate is reduced to conserve battery life. This dynamic behavior resolves the contradiction between ensuring network availability and preserving battery life.
Solution Approach 2:
The network system automatically monitors handover counts and self-adjusts the rescan rate parameters without requiring manual intervention. The system serves itself by using its own performance metrics (handover counts) to optimize its scanning behavior, thereby automatically balancing network availability against energy consumption based on actual roaming conditions.
3Device complexity
If fixed network rescan rates are used for all roaming devices, then device complexity is reduced, but network efficiency and resource utilization worsen
Solution Approach 1:
The patent implements feedback by monitoring roaming handover counts and using this information to adjust network rescan rates. The system measures actual handover activity, compares it to thresholds, and feeds this information back to modify the scanning behavior. This feedback mechanism enables the network to efficiently adapt to different roaming conditions without requiring complex device-side decision-making, thereby improving network efficiency while maintaining manageable device complexity.
Solution Approach 2:
The system changes the network rescan rate parameter based on measured handover performance. Rather than using a single fixed rate for all devices, the network dynamically modifies the rescan rate parameter according to actual roaming handover counts. This parameter adaptation improves network efficiency by optimizing scan frequency to match actual roaming needs, while the network-centric implementation keeps device complexity low.
