IoT Device APN Verification for Service Restriction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems lack effective mechanisms to restrict IoT devices to specific services, leading to potential unauthorized communications across unsupported networks, which can compromise security and network resource allocation.
Innovation Solution
Implementing a method where IoT devices obtain APN information, determine if it matches authorized APNs, and prohibit communications if there is a mismatch, ensuring that devices only connect to networks that support the indicated services by using access point name (APN) information during network discovery and provisioning procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If IoT devices are allowed to communicate across multiple networks without restriction, then network versatility and connectivity are improved, but security and unauthorized access risks worsen
Solution Approach 1:
The patent implements service-based restriction mechanisms during network discovery and provisioning procedures before actual communications occur. The IoT device determines its services and restricts network access based on service compatibility during the initial connection phase, preventing unauthorized communications before they can compromise security.
2Reliability
If IoT devices are restricted to specific services through APN verification, then security and network resource allocation are improved, but device complexity and provisioning overhead worsen
Solution Approach 1:
The patent enables IoT devices to autonomously determine their own services and perform self-verification against available APNs without requiring complex external provisioning infrastructure. The device independently obtains APN information, determines service compatibility, and restricts communications based on matching criteria, reducing the need for manual configuration and external verification systems.
Solution Approach 2:
The patent implements a feedback mechanism where the IoT device receives APN information from network entities, compares it against its authorized services, and adjusts its communication behavior accordingly. The device obtains service information, verifies APN compatibility, and provides feedback by either establishing or prohibiting communications based on the verification result.
3Object-affected harmful factors
If APN verification is performed during network discovery, then unauthorized communications are prevented, but network discovery time and provisioning duration worsen
Solution Approach 1:
The patent performs service determination and APN verification during the initial network discovery and provisioning phase, before any actual data communications occur. By establishing service-based restrictions upfront during network attachment procedures, the system prevents unauthorized communications from occurring in the first place, rather than requiring ongoing verification that would extend communication time.

AI summary
Aspects described herein relate to obtaining, by a device, access point name (APN) information corresponding to a network entity, the APN information indicating one or more available APNs, determining whether at least one APN of the one or more available APNs indicated in the obtained APN information matches authorized APN information stored in the device, and prohibiting communications for the device that correspond to the at least one APN based at least in part on the determination that the at least one APN is not indicated in the authorized APN information.
