Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote subscription provisioning procedures use extra nodes such as SM-SR and node-specific interfaces, then profile delivery can be achieved, but system complexity increases and integration becomes complex
Solution Approach 1:
The patent extracts and removes the SM-SR node from the provisioning architecture. The subscription server directly communicates with the communication device using standardized protocols, eliminating the need for the intermediate SM-SR node and its node-specific interfaces, thereby reducing system complexity while maintaining profile delivery capability
Solution Approach 2:
The subscription server is designed to perform multiple functions directly, including profile generation, localization decision-making, and direct communication with diverse device types (consumer and M2M) using standardized protocols, replacing the need for specialized intermediate nodes
2Ease of manufacture
If remote subscription provisioning procedures rely on outdated communication protocols, then existing systems can be used, but compatibility with modern communication devices is lost
Solution Approach 1:
The patent changes the communication protocol parameters from outdated protocols to currently supported standardized protocols. The subscription server communicates using modern protocols that are fully supported by both consumer and M2M communication devices, ensuring both backward compatibility and forward adaptability
3Reliability
If manual profile provisioning is used, then profile accuracy can be ensured, but automation is lost and efficiency decreases
Solution Approach 1:
The system enables self-service provisioning where the subscription server automatically performs localization decisions and triggers profile downloads based on device type information and localization rules, eliminating manual intervention while maintaining accuracy through rule-based automated decision-making
Solution Approach 2:
The system implements feedback mechanisms where the subscription server receives device type information from the proxy server, processes it through localization rules, and automatically adjusts provisioning actions accordingly, ensuring accurate profile delivery through automated feedback loops
4Productivity
If location-specific profiles are provisioned after device manufacturing, then profile optimization for current location is achieved, but additional provisioning steps are required
Solution Approach 1:
The system performs preliminary localization decisions and profile preparation actions automatically when the device first connects to the network. The subscription server proactively determines the appropriate location-specific profile and triggers the download before the device needs to use optimized services, eliminating delays

AI summary
There is provided mechanisms for profile handling of a communication device. A method is performed by a subscription server. The method comprises obtaining device type information of the communication device from a proxy server. The method comprises determining a profile handling action for the communication device according to at least one localization rule. According to which of the localization rule the profile handling action is determined depends on a mapping between the device type information and the localization rule. The method comprises notifying the proxy server of the profile handling action.
