Subscriber Profile Provisioning for Secure Module Parameter Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for updating secure modules in mobile communications terminals do not adequately address the need to synchronize the terminal's operating environment parameters with the new operator's settings, leading to potential service disruptions due to parameter mismatches.
Innovation Solution
A method and system for provisioning a subscriber profile to a terminal with a secure module, involving receiving a provisioning request from a remote server containing both the subscriber profile and associated terminal parameters, loading the profile into the secure module, and configuring the terminal's operating environment based on activation notifications from the secure module.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the secure module is updated with a new operator profile, then the subscriber can access new services, but the terminal parameters may mismatch with the new profile causing service disruption
Solution Approach 1:
The terminal receives and stores new operator parameters in advance, before activating the new profile. This preliminary configuration ensures that when the profile switches, the terminal is already prepared with the correct parameters, avoiding service disruption and maintaining reliability while enabling adaptability to new operators
Solution Approach 2:
A parameter management mechanism acts as an intermediary between the secure module profile updates and the terminal configuration. This intermediary ensures that parameters are properly synchronized and matched with the active profile, preventing mismatches that would cause service disruption while allowing flexible operator changes
2Reliability
If the terminal parameters are updated along with the profile, then service continuity is maintained, but the complexity of the provisioning process increases
Solution Approach 1:
The profile update and parameter update processes are merged into a single integrated provisioning operation. When a new profile is installed, the associated parameters are automatically received and configured in the same transaction, ensuring service continuity without requiring separate manual configuration steps, thus managing complexity while maintaining reliability
3Ease of manufacture
If the terminal remains configured with the initial operator parameters, then the configuration is simple, but parameter mismatch prevents proper connection to new operator services
Solution Approach 1:
The terminal configuration is made dynamic rather than static. Parameters are automatically updated to match the active profile, allowing the terminal to adapt seamlessly when switching operators. This dynamic approach maintains ease of initial setup while enabling full adaptability to new services through automated parameter synchronization

AI summary
Described are methods and systems for provisioning a subscriber profile in a secure module, such as a SIM card. The methods and systems may perform operations that may include receiving a request for provisioning a subscriber profile accompanied by parameters of a mobile terminal associated with the subscriber profile, and configuring the terminal when notification is received of the profile being activated, the notification coming from the secure module. Variations of the systems and methods are applicable to terminals including a secure module for hosting a subscriber profile to a mobile communications network.
