Zero-touch Cellular IoT Device Onboarding via Private APN
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The onboarding of cellular IoT devices is needlessly complex, requiring human intervention and leading to security weaknesses, increased costs, and operational complexity, as it often involves customizing devices during manufacturing or configuring them in the field, which results in shared secrets and increased deployment time.
Innovation Solution
Implementing zero-touch deployment (ZTD) with an onboarding agent that enables devices to register and onboard securely via a cellular connection, using integrated circuit card identifiers (ICCID) or international mobile equipment identity (IMEI) for authentication, and leveraging embedded SIMs (eSIM, iSIM) for per-device customization without complex backend processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices are customized during manufacturing or configured in the field, then per-device security can be achieved, but deployment complexity and time increase significantly
Solution Approach 1:
The patent applies preliminary action by pre-provisioning devices with unique identifiers (IMEI/ICCID) and security credentials during manufacturing, but deferring actual configuration and customization to occur automatically in the field through zero-touch deployment. This allows per-device security to be established without requiring complex manual configuration processes, as the device autonomously completes its setup using pre-configured credentials and automated enrollment procedures.
2Reliability
If manual configuration is required for device onboarding, then security can be maintained, but deployment time and costs increase
Solution Approach 1:
The patent implements self-service through zero-touch deployment where devices automatically perform their own configuration, enrollment, and setup procedures without human intervention. The device uses its unique identifiers to autonomously retrieve security credentials, register with services, and configure itself securely. This eliminates manual configuration steps while maintaining security through automated enforcement of security policies and credential distribution.
3Device complexity
If shared secrets are used across devices, then deployment complexity decreases, but security is weakened
Solution Approach 1:
The patent applies local quality by ensuring each device has its own unique security credentials and identifiers (IMEI/ICCID-specific) rather than sharing common secrets. The system provisions device-specific certificates, keys, and security parameters tailored to each individual device's identity. This creates localized security per device while maintaining simplified automated deployment through standardized enrollment processes that work uniformly across all devices.
4Adaptability or versatility
If per-device customization is implemented, then security and adaptability improve, but backend process complexity increases
Solution Approach 1:
The patent applies universality by creating a standardized zero-touch deployment framework that handles diverse per-device customization needs through a single unified process. The system uses common protocols and mechanisms (automated enrollment, credential provisioning, service registration) that work across different device types, service providers, and customization requirements. This universal approach enables per-device adaptability without requiring complex specialized backend processes for each scenario.
Data Source
AI summary
In one embodiment, a service receives a device registration request sent by an endpoint device, wherein the endpoint device executes an onboarding agent that causes the endpoint device to send the device registration request via a cellular connection to a private access point name (APN) associated with the service. The service verifies that a network address of the endpoint device from which the device registration request was sent is associated with an integrated circuit card identifier (ICCID) or international mobile equipment identity (IMEI) indicated by the device registration request. The service identifies a tenant identifier associated with the ICCID or IMEI. The service sends, based on the tenant identifier, a device registration response to the endpoint device via the private APN.
