Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional access point devices use separate spectrum allocation for cellular and WLAN communications, then each communication standard can be optimized independently, but the overall spectrum utilization efficiency deteriorates and operational costs increase
Solution Approach 1:
The patent combines cellular and WLAN spectrum allocation into a unified management system that dynamically allocates frequency bands across both communication standards. The spectrum management device consolidates licensed and unlicensed spectrum resources, allowing simultaneous optimization of both cellular and WLAN communications while improving overall spectrum utilization efficiency and reducing operational costs through shared resource management.
Solution Approach 2:
The spectrum management device performs universal spectrum allocation functions for both cellular and WLAN access point devices. It manages both licensed and unlicensed frequency bands across multiple communication standards, providing a multi-functional platform that can dynamically allocate spectrum resources based on varying network demands and service requirements.
2Adaptability or versatility
If access point devices are statically configured with fixed frequency bands, then device complexity is reduced, but adaptability to changing network demands deteriorates
Solution Approach 1:
The patent introduces a spectrum management device as an intermediary between access point devices and spectrum resources. This mediator handles the complex task of dynamic spectrum allocation, allowing access point devices to remain relatively simple while adapting to changing network demands. The spectrum management device receives allocation requests, determines optimal frequency band assignments, and configures access point devices accordingly, thus providing adaptability without significantly increasing access point device complexity.
Solution Approach 2:
The system implements dynamic spectrum allocation where frequency band assignments are not fixed but can be adjusted in real-time based on network conditions, traffic patterns, and service requirements. The spectrum management device continuously monitors network state and reconfigures frequency band allocations dynamically, enabling access point devices to adapt to changing demands while the management system handles the complexity of coordination and optimization.
3Reliability
If private networks allocate sufficient frequency bands for peak load requirements, then network reliability is improved during high-demand periods, but operational costs increase due to underutilization during low-demand periods
Solution Approach 1:
The patent implements dynamic spectrum allocation that adjusts frequency band assignments based on real-time network load conditions. During peak demand periods, the spectrum management device allocates additional frequency bands to ensure network reliability and sufficient capacity. During low-demand periods, it reduces allocations to minimize operational costs, thus achieving cost-effective network operation while maintaining required service levels through on-demand resource provisioning.
Solution Approach 2:
The system changes spectrum allocation parameters dynamically based on network conditions. The spectrum management device monitors traffic patterns, user density, and service requirements, then adjusts the number and configuration of frequency bands allocated to access point devices. This parameter adjustment ensures adequate network capacity during peak loads while optimizing resource utilization and reducing costs during off-peak periods.
4Measurement precision
If spectrum allocation is performed manually for each access point device, then allocation precision can be optimized for each device, but the time and complexity of spectrum management increases
Solution Approach 1:
The spectrum management device implements automated self-service spectrum allocation by monitoring network conditions, determining optimal frequency band assignments, and configuring access point devices without manual intervention. The system automatically evaluates spectrum availability, predicts traffic patterns, and adjusts allocations in real-time, thus maintaining precise spectrum allocation while eliminating the time-consuming manual configuration process for each access point device.
Solution Approach 2:
The system employs feedback mechanisms where the spectrum management device continuously monitors network performance, traffic patterns, and spectrum utilization metrics. Based on this feedback, it automatically adjusts spectrum allocations to optimize performance for each access point device. The feedback loop enables precise, adaptive spectrum management that responds to changing conditions in real-time without requiring manual reconfiguration of each device.
