Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a large number of IoT devices are integrated into existing networks, then network connectivity and service coverage are improved, but network signaling load and system complexity increase significantly
Solution Approach 1:
The patent segments access control by introducing access categories (0-31) and access identities (0-15), dividing the network access control into multiple independent groups. This allows different IoT device types to be managed separately, reducing overall signaling complexity while maintaining comprehensive coverage.
Solution Approach 2:
The patent introduces scaling factors (SF) that can be configured by the network to dynamically adjust access control parameters. By changing these parameters, the network can adapt to different load conditions and device types without restructuring the entire access control system.
2Manufacturing precision
If access control parameters are configured for each IoT device type, then access control precision is improved, but configuration complexity and signaling overhead increase
Solution Approach 1:
By segmenting access control into categories and identities, the patent enables precise control for different device types while organizing configurations in a structured manner that reduces overall complexity.
Solution Approach 2:
The access category and access identity framework serves multiple functions simultaneously: device classification, access control, load management, and signaling optimization, reducing the need for separate configuration systems.
3Reliability
If access control operations are executed for each access attempt, then access control effectiveness is improved, but processing time and operational overhead increase
Solution Approach 1:
The terminal device determines its access category and identity in advance before actual access attempts. This preliminary classification allows for faster processing during actual access operations, as the device already knows which control rules apply.
Solution Approach 2:
The scaling factor mechanism allows the network to adjust access control stringency dynamically. During high-load periods, scaling factors can be reduced to decrease processing overhead while maintaining basic control effectiveness.
