Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data network modules are configured for specific regions and struggle to comply with varying regulatory constraints across different regions, and they require complex registration processes with multiple network operators.
Innovation Solution
A global data network system that uses a common registration database to provision modules for secure communication across multiple regions, employing a node ID and access code system to ensure secure registration and key management across different network operators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modules are configured for a particular region during manufacturing, then they can comply with regional regulations, but they cannot operate in multiple regions without complex reconfiguration
Solution Approach 1:
The patent implements dynamic configuration where modules can change their operational parameters based on the region they are currently in. The system dynamically adjusts configuration settings when modules roam between regions, allowing a single module to adapt to different regional requirements without manual reconfiguration or complex pre-programming for multiple regions.
Solution Approach 2:
The patent introduces a home network as an intermediary that manages module configuration. When modules roam between visited networks, the home network acts as a mediator that provides configuration information and maintains registration, allowing modules to operate in multiple regions without carrying complex multi-region configurations themselves.
2Adaptability or versatility
If modules register with multiple network operators for multi-regional roaming, then they can operate across regions, but the registration process becomes complex
Solution Approach 1:
The patent merges the registration process by allowing modules to register with a single home network that then manages relationships with multiple visited networks. This consolidation reduces the complexity of registering with each network operator individually while maintaining the ability to roam across multiple networks and regions.
Solution Approach 2:
The home network serves as a universal registration point that handles multiple functions: initial module registration, configuration management, and coordination with visited networks. This multi-functional approach simplifies the overall registration process while enabling multi-network roaming capability.
3Device complexity
If a single key is used for secure communication across all networks, then key management is simplified, but security is compromised
Solution Approach 1:
The patent segments the key management system by associating unique keys with specific network operators. Modules have different keys for different networks, and the home network manages this segmented key structure. This segmentation maintains security by ensuring that compromise of one network's key does not affect others, while the centralized home network management keeps the overall system manageable.

AI summary
Methods, systems, and apparatuses, including computer programs encoded on computer-readable media, configured to receive, at a module from a provisioning server, a node identification and an access code. The module joins a network that the module has not previously joined. The module provides the node identification to the network. The network uses the node identification and access code to verify that the module is valid. The module receives from the network a new encryption key to use when sending data on the network. The module encrypts data using the new encryption key. The encrypted data is transmitted on the network.
