Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single rigid paging format is used in current 5G networks, then device compatibility is maintained, but network performance is suboptimal due to excessive signaling and resource inefficiency
Solution Approach 1:
The patent implements dynamic paging format selection where the network node chooses from multiple paging formats (compact, standard, extended) based on real-time parameters including message size, latency requirements, and device capabilities. This dynamic adaptation allows the system to optimize performance for different scenarios while maintaining a manageable level of complexity through structured format definitions and selection criteria.
2Reliability
If paging messages are transmitted with high reliability for critical MTC, then transmission robustness is improved, but latency increases due to repeated transmissions and acknowledgments
Solution Approach 1:
The patent changes key transmission parameters based on the paging format selected. For compact formats targeted at critical MTC, the system adjusts message condensation level, modulation schemes, and resource allocation to achieve high reliability with reduced transmission time. The extended format provides alternative parameter settings for scenarios where latency can be tolerated for higher robustness.
3Use of energy by moving object
If compact paging formats are used for low-power devices, then energy consumption is reduced, but information completeness is compromised
Solution Approach 1:
The patent segments paging information into essential and optional components. Compact formats transmit only essential information (device identification and basic paging indication) to minimize energy consumption. Additional information is either transmitted in subsequent messages or pre-configured in the device, thereby maintaining information completeness while reducing the energy required for initial paging reception.
4Quantity of substance
If extended paging formats are used for large messages, then information capacity is increased, but signaling overhead and resource utilization deteriorate
Solution Approach 1:
The patent dynamically selects extended paging formats only when the message size parameter exceeds a threshold. For smaller messages, compact or standard formats are used to conserve network resources. The system adapts the paging format based on real-time assessment of message capacity requirements versus available network resources, optimizing the balance between information capacity and resource efficiency.
