Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT devices perform mobility update when moving out of registration area, then mobility management is maintained, but power consumption increases and device complexity increases
Solution Approach 1:
The patent changes the mobility reporting parameters by introducing conditional reporting based on registration area changes rather than continuous reporting. The network device configures the terminal device to report mobility information only when specific conditions are met (e.g., when leaving a registration area), thereby reducing power consumption while maintaining mobility management reliability.
Solution Approach 2:
The patent implements periodic mobility reporting where the terminal device reports mobility information at specific intervals or triggers rather than continuously. The network device can configure reporting periods or trigger conditions, allowing the device to conserve power by remaining in low-power states between reporting instances while still maintaining effective mobility management.
2Reliability
If IoT devices perform mobility update when moving out of registration area, then mobility management is maintained, but device complexity increases
Solution Approach 1:
The patent enables the terminal device to autonomously determine when to report mobility information based on configured conditions and triggers. The device monitors its own location relative to registration areas and automatically initiates reporting when conditions are met, reducing the need for complex network-controlled mobility management procedures.
Solution Approach 2:
The patent simplifies device complexity by changing the mobility reporting parameters from continuous to conditional/periodic reporting. The network device provides configuration parameters that guide the terminal device's reporting behavior, reducing the computational and processing complexity required in the device while maintaining reliable mobility management.
3Productivity
If network devices receive mobility information timely, then mobility management is optimized, but communication overhead increases
Solution Approach 1:
The patent reduces communication overhead by implementing periodic or trigger-based mobility reporting instead of continuous reporting. The terminal device sends mobility information at configured intervals or when specific events occur (e.g., leaving a registration area), providing timely updates to the network device while minimizing unnecessary communication traffic.
Solution Approach 2:
The patent optimizes the balance between mobility management efficiency and communication overhead by changing reporting parameters. The network device configures reporting frequency, triggers, and conditions that ensure mobility information is received timely for effective management while reducing the quantity of communication messages compared to continuous reporting schemes.
