Engineering Contradiction Analysis
1Adaptability or versatility
If traditional access control methods are used for zero power consumption terminals, then system compatibility is maintained, but the unique capabilities of zero power consumption terminals cannot be effectively supported
Solution Approach 1:
The network device implements a universal access control mechanism that handles both traditional terminals and zero power consumption terminals through a unified framework. The first indication information structure is designed to work across different terminal types, with specific fields (like second indication information for capability types) that enable multi-functionality without requiring separate access control systems for different terminal categories.
Solution Approach 2:
The access control information is segmented into multiple independent indication information fields, where each field controls a specific aspect: first indication information for access permission, second indication information for capability type, third indication information for power consumption characteristics. This segmentation allows the system to selectively apply different access control rules based on terminal capabilities without increasing overall system complexity.
2Reliability
If access control information is provided for all terminal types, then comprehensive control is achieved, but information overhead increases
Solution Approach 1:
The system implements partial indication by providing only the necessary access control information fields for each terminal type. Traditional terminals receive standard access control information, while zero power consumption terminals receive additional capability-specific fields. This partial approach ensures comprehensive control for each terminal type without transmitting excessive information overhead for all terminal types universally.
Solution Approach 2:
Different portions of the indication information structure are optimized for different terminal types. The first indication information provides universal access control, while the second indication information specifically addresses zero power consumption terminal capabilities. This local quality optimization ensures that each terminal type receives precisely the information it needs without unnecessary overhead.
3Ease of manufacture
If zero power consumption terminals access the system, then ultra-low cost and zero power consumption benefits are achieved, but access control challenges arise due to different capabilities
Solution Approach 1:
The network device acts as an intermediary that translates between the simple capability indicators from zero power consumption terminals and the detailed access control policies. The terminal sends minimal capability information (second indication information), and the network device uses this to retrieve or determine appropriate access control parameters, thereby simplifying the terminal's operation while maintaining comprehensive access control.
Solution Approach 2:
The network device pre-configures access control policies for different terminal capability types. When a zero power consumption terminal accesses the system, it only needs to indicate its capability type, and the network device has already prepared the appropriate access control parameters. This preliminary action eliminates the need for complex real-time access control negotiations, simplifying terminal operation.
