Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a terminal device determines communication mode autonomously without network assistance, then device complexity is reduced, but communication performance deteriorates in overlapping or discontinuous coverage scenarios
Solution Approach 1:
The network device acts as an intermediary that provides indication information to assist the terminal device in determining the appropriate communication mode. This mediator supplies critical network status information (such as coverage status, load status, and configuration status of different networks) that enables the terminal to make informed decisions without bearing the full complexity of autonomous determination in complex overlapping coverage scenarios.
2Reliability
If the terminal device autonomously determines communication mode in overlapping coverage scenarios, then network assistance is reduced, but communication performance deteriorates
Solution Approach 1:
The network device serves as an intermediary that provides indication information containing network status and configuration data. This approach improves communication performance by enabling informed mode selection while reducing terminal power consumption compared to full autonomous determination, as the terminal leverages pre-processed network information rather than performing complex autonomous analysis.
Solution Approach 2:
The network device performs preliminary actions by determining and providing indication information about network status (coverage, load, configuration) before the terminal device needs to make communication mode decisions. This advance preparation of information reduces the computational burden and power consumption of the terminal device while ensuring accurate mode selection.
3Reliability
If indication information is provided by network device, then communication performance improves, but device complexity increases
Solution Approach 1:
The network device utilizes its own inherent capabilities to determine and provide indication information. The network device already possesses knowledge of network status (coverage, load, configuration) as part of its normal operation, so it can generate the required indication information using its existing resources without requiring additional complex external systems.
4Productivity
If terminal device performs autonomous mode selection, then network processing is reduced, but mode selection accuracy deteriorates in complex scenarios
Solution Approach 1:
The network device acts as an intermediary that provides accurate indication information about network status to the terminal device. This enables the terminal to make accurate mode selection decisions in complex overlapping coverage scenarios by leveraging the network device's comprehensive knowledge of network conditions, achieving both speed and accuracy.
Solution Approach 2:
The network device performs preliminary determination of network status and generates indication information in advance, providing the terminal device with accurate data needed for precise mode selection. This preliminary action ensures that the terminal has access to reliable network information without delaying the mode selection process.
