Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the network device fixedly configures the measurement gap mode, then the system operation is simplified, but the measurement accuracy deteriorates due to mismatch with terminal device characteristics
Solution Approach 1:
The patent transforms the static, fixed measurement gap mode configuration into a dynamic, adjustable configuration. The network device can now flexibly configure different measurement gap modes (first mode with longer gap period, second mode with shorter gap period) based on terminal device characteristics such as movement speed, enabling the system to adapt to changing conditions while maintaining operational simplicity
Solution Approach 2:
The patent changes the measurement gap mode parameters (gap period, measurement timing) based on terminal device characteristics. By adjusting these parameters dynamically according to movement speed and other factors, the system achieves higher measurement accuracy without significantly increasing operational complexity
2Ease of manufacture
If the measurement gap mode is fixedly configured by the network device, then the configuration process is simplified, but the system performance deteriorates due to inability to adapt to terminal characteristics
Solution Approach 1:
The patent introduces dynamic adaptability by enabling the network device to configure different measurement gap modes based on terminal characteristics such as movement speed. The system can switch between first measurement gap mode (for high-speed terminals) and second measurement gap mode (for low-speed terminals), achieving both ease of configuration and adaptability
Solution Approach 2:
The patent adjusts measurement gap parameters dynamically based on terminal device characteristics. By changing the gap period and measurement timing parameters according to movement speed and other factors, the system maintains configuration simplicity while achieving high adaptability to different terminal scenarios
3Use of energy by moving object
If a longer measurement gap period is used, then the terminal device power consumption is reduced, but the measurement accuracy deteriorates due to insufficient sampling frequency
Solution Approach 1:
The patent dynamically adjusts the measurement gap period parameter based on terminal movement speed. For high-speed terminals, a longer gap period is used to reduce power consumption; for low-speed terminals, a shorter gap period is used to ensure sufficient sampling frequency and measurement accuracy. This parameter adaptation resolves the contradiction between power consumption and measurement accuracy
4Measurement precision
If a shorter measurement gap period is used, then the measurement accuracy is improved due to higher sampling frequency, but the terminal device power consumption increases
Solution Approach 1:
The patent avoids using a uniformly short measurement gap period by introducing conditional parameter selection. Based on terminal movement speed and characteristics, the system selectively applies short gap periods only when necessary (for low-speed terminals requiring high accuracy) and uses longer gap periods for high-speed terminals where power saving is prioritized, thus resolving the contradiction between measurement accuracy and power consumption
