MNO Credential Distribution for Embedded UICC Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In machine-to-machine communications, embedded Universal Integrated Circuit Cards (UICCs) in devices like automobile engines or streetlights cannot be easily replaced or re-provisioned, making it difficult for subscribers to switch to different Mobile Network Operators (MNOs without replacing the entire device.
Innovation Solution
A method and system for distributing MNO credentials, allowing devices to select and switch between MNOs by transmitting credential information between equipment, enabling peer-to-peer provisioning and seamless service continuity without requiring physical replacement of the UICC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the UICC is embedded in the communication device, then the device can operate in harsh environments and provide continuous service, but the subscriber cannot easily switch to another MNO by physical replacement
Solution Approach 1:
The patent uses remote provisioning to create a virtual copy of the UICC's credential storage functionality in the cloud. Instead of physically replacing the embedded UICC, the system copies the necessary credential data and provisioning information to enable MNO switching while maintaining the embedded physical form factor and service continuity.
Solution Approach 2:
The patent introduces a remote provisioning server as an intermediary between the embedded UICC and the MNO authentication system. This server mediates the credential distribution process, allowing the embedded UICC to receive updated credentials remotely without physical replacement, thus enabling MNO switching while maintaining reliability.
2Adaptability or versatility
If the UICC is physically replaced to switch MNOs, then the subscriber can change network operators, but the device must be replaced which increases complexity and cost
Solution Approach 1:
The system creates a virtual copy of the UICC's credential storage and management functionality in a remote provisioning server. This allows the embedded UICC to switch MNOs by receiving updated credentials remotely, eliminating the need for physical device replacement and reducing complexity.
Solution Approach 2:
The patent replaces the mechanical process of physically replacing the UICC card with a digital/software-based remote provisioning mechanism. The credential update process is substituted from physical insertion/removal to wireless data transmission, eliminating device replacement requirements and reducing complexity.
3Adaptability or versatility
If remote provisioning is implemented, then MNO switching becomes possible without device replacement, but secure credential transmission and storage becomes more complex
Solution Approach 1:
The patent introduces a remote provisioning server as a secure intermediary that handles all credential transmission and storage operations. This dedicated intermediary component simplifies the overall system architecture by centralizing security functions, making secure credential distribution manageable despite the added complexity of remote provisioning.

AI summary
A system that incorporates teachings of the subject disclosure may include, for example, a method for detecting, by a first device including a least one processor and a first Universal Integrated Circuit Card (UICC), a second device having a second UICC, detecting, by the first device, that the second UICC is unprovisioned, selecting, by the first device, one of a plurality of selectable options, where the selection identifies a first Mobile Network Operator (MNO) selected from a plurality of MNOs, receiving, by the first device, first credential information of the first MNO, and transmitting, by the first device, to the second device the first credential information for enabling the second device to facilitate establishment of communication services with network equipment of the first MNO according to the first credential information. Other embodiments are disclosed.
