Identification Unit Remote Provisioning via Tunnel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices with limited access to remote provisioning servers, such as those operating outside their home network or within virtual private networks, face challenges in accessing remote provisioning services due to access limitations, particularly when they lack packet-switched connections or TCP/IP capabilities.
Innovation Solution
A method that enables wireless communication devices to download subscription information by using basic packet-based communication protocols to establish a connection tunnel through a cellular network, allowing the identification unit to submit requests to a remote provisioning server, even with limited access, by employing advanced packet-based communication protocols and cryptographic coding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If wireless communication devices use basic packet-based communication protocol means, then device complexity and cost are reduced, but the ability to access remote provisioning servers is limited
Solution Approach 1:
The identification unit acts as an intermediary between the wireless communication device and the remote provisioning server. It contains advanced packet-based communication protocol means that enable the device to access the server despite the device's limited capabilities. The identification unit translates and forwards requests using appropriate protocols, bridging the gap between simple devices and complex server requirements.
2Reliability
If wireless communication devices operate with limited access modes, then security and network control are improved, but remote provisioning capability is reduced
Solution Approach 1:
The system separates communication capabilities into two segments: the wireless communication device uses basic protocols for normal operation under security constraints, while the identification unit contains advanced protocol means for remote provisioning. This segmentation allows the device to operate securely with limited access while still enabling provisioning through the more capable identification unit.
3Device complexity
If wireless communication devices lack TCP/IP capabilities, then device cost and complexity are reduced, but ability to perform remote provisioning is lost
Solution Approach 1:
The identification unit serves multiple functions: it acts as an authentication credential holder, a communication protocol adapter, and a remote provisioning client. By embedding advanced packet-based communication protocol means in the identification unit, the system enables TCP/IP-based remote provisioning without requiring the wireless communication device itself to have these capabilities, making the identification unit a multi-functional component that bridges capability gaps.
