Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing IoT management platforms face challenges in efficiently managing large quantities of IoT devices, particularly in coordinating between device management servers and connectivity management servers due to separate handling of SIM card and device information.
Innovation Solution
An IoT device data management method that establishes a correspondence between a device and a SIM card, allowing for mutual cooperation between the connectivity management server and the device management server by storing and synchronizing device and SIM card identifiers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device management server and connectivity management server separately manage device information and SIM card information, then each server can independently perform its management functions, but collaboration between the two servers becomes difficult and inefficient
Solution Approach 1:
The patent merges device information and SIM card information into a unified data structure with a one-to-one correspondence relationship. The device management server and connectivity management server both access and maintain this unified data structure, enabling efficient collaboration while preserving independent management capabilities through standardized access interfaces.
2Productivity
If device management server stores both device identifier and SIM card identifier, then data collection efficiency improves and data accuracy is ensured, but data storage and synchronization complexity increases
Solution Approach 1:
The unified data structure serves multiple functions: it stores device identifiers, SIM card identifiers, and their correspondence relationships; it enables both device management and connectivity management operations; and it provides a single source of truth for data synchronization between servers, reducing overall system complexity despite increased storage requirements.
3Reliability
If device management server and connectivity management server establish mutual correspondence, then cooperative operations become efficient, but system initialization and maintenance overhead increases
Solution Approach 1:
The correspondence relationship between device identifiers and SIM card identifiers is established in advance during device registration and SIM card binding operations. The unified data structure is pre-populated with this mapping information, enabling rapid cooperative operations between servers without requiring real-time establishment of relationships during runtime collaboration.

AI summary
In an IoT device data management method, an IoT device sends a data report message to a device management server, to report a device identifier of the IoT device and a SIM card identifier of a SIM card in the IoT device. The device management server stores the device identifier and the SIM card identifier, and may further synchronize the device identifier and the SIM card identifier to a connectivity management server. In this way, the device management server establishes and maintains a correspondence between the device identifier of the IoT device and the SIM card identifier.
