Mobile Device Service Provider Activation via Signed Tickets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
GSM mobile devices with service provider locks face revenue loss and logistical complexity for manufacturers, and consumer inconvenience due to restrictions on using SIM cards from different providers.
Innovation Solution
A method for service provider activation in mobile devices that involves a signing process to store an activation ticket incorporating device and SIM card information, and an activation process to verify this ticket, allowing the device to operate with multiple service providers by generating and validating activation tickets securely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a service provider lock is implemented in a mobile device, then the device is restricted to work with a particular service provider's SIM cards, but this results in revenue loss for the service provider and logistical complexity for the manufacturer
Solution Approach 1:
The patent segments the service provider lock mechanism into separate components: a base device without hard-coded locks, individual service provider-specific lock codes, and an activation system. This allows the same device hardware to be sold to multiple service providers without requiring different manufacturing lines, reducing manufacturing complexity while maintaining service provider restrictions through software-based lock codes.
Solution Approach 2:
The patent introduces an intermediary activation system that mediates between the device and service providers. This system stores and verifies service provider lock codes, allowing devices to be activated for different service providers without requiring different hardware. The intermediary handles the complexity of managing multiple service provider restrictions, simplifying the device manufacturing process.
2Reliability
If a service provider lock is implemented in a mobile device, then the device is restricted to work with a particular service provider's SIM cards, but this leads to loss of revenue for the service provider when codes are compromised
Solution Approach 1:
The patent implements preliminary action by requiring device activation before use. The service provider lock codes are verified during an activation process that occurs before the device can be used with the service provider's network. This preliminary verification ensures that only authorized devices are activated, preventing revenue loss from compromised codes while maintaining reliable service provider restrictions.
Solution Approach 2:
The patent incorporates feedback mechanisms where the activation system continuously verifies service provider lock codes and maintains records of activated devices. This feedback loop allows the service provider to monitor and control device access, ensuring that restricted devices remain restricted and preventing revenue loss from unauthorized usage.
3Adaptability or versatility
If a service provider lock is implemented in a mobile device, then the device is restricted to work with a particular service provider's SIM cards, but this causes inconvenience for consumers who want to switch providers
Solution Approach 1:
The patent implements dynamics by making the service provider lock status changeable through activation and deactivation processes. Instead of a fixed hard-coded restriction, the device's service provider association can be dynamically modified by the consumer through the activation system, allowing flexibility to switch providers while maintaining controlled access through the activation mechanism.

AI summary
Systems and methods for activating a mobile device for use with a service provider are described. In one exemplary method, a mobile device having a currently inserted SIM card may be prepared for activation using a signing process in which an activation server generates a signed activation ticket that uniquely corresponds to the combination of the device and SIM card, and that is securely stored on the mobile device. In another exemplary method the mobile device may be activated in an activation process in which the device verifies an activation ticket against information specific to the device and SIM card, and initiates activation when the verification of the activation ticket is successful.
