Dynamic Allowed Area List Reset Mechanism for IoT Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Next-generation networks require an efficient mechanism to manage dynamically generated allowed area lists for user equipment, as existing solutions struggle to dynamically allocate and update allowed areas, leading to potential misuse and operational challenges, especially for IoT devices with varying locations and mobility patterns.
Innovation Solution
Implementing a mechanism where user equipment can trigger a reset of its dynamic allowed area list, with network nodes determining whether to reset it based on request messages, and setting a quarantine time to prevent frequent reset attempts, thereby controlling the change rate of allowed areas and preventing misuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the DAA list is dynamically updated to support IoT devices with varying locations, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic allowed area lists that can be automatically updated and modified during device operation. The DAA list is not static but can change based on device location, mobility patterns, and network conditions, allowing the system to adapt to varying IoT device requirements without requiring complex manual configuration
Solution Approach 2:
The system enables automated management of allowed area lists through self-service mechanisms. Network nodes automatically determine whether to reset the DAA list based on received request messages, and quarantine times are automatically set to prevent frequent reset attempts, reducing the need for manual operator intervention and simplifying device management
2Ease of operation
If operator intervention is reduced for automatic management, then ease of operation is improved, but reliability may worsen due to potential misuse
Solution Approach 1:
The patent implements feedback mechanisms where network nodes monitor reset request messages from devices and automatically adjust quarantine times based on observed behavior. When frequent reset attempts are detected, the system automatically extends quarantine periods, creating a self-regulating mechanism that maintains reliability while enabling automated operation
Solution Approach 2:
The system preemptively prevents potential misuse by implementing quarantine times before actual problems occur. When a reset request is received, the network node proactively sets a quarantine period that prevents subsequent reset attempts during that time, stopping potential abuse patterns before they can compromise system reliability
3Ease of operation
If frequent reset attempts are allowed, then ease of operation is improved, but productivity worsens due to service disruption
Solution Approach 1:
The patent implements periodic action through quarantine times that create structured intervals between allowed reset operations. Instead of allowing continuous or frequent resets, the system enforces periodic waiting periods that prevent service disruption while still permitting operational flexibility within defined time windows
