Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple eSIM profiles are enabled simultaneously on a single eSIM, then the device can support multiple network operators or services, but contactless interface access is limited to a single profile at a time
Solution Approach 1:
The patent segments the contactless interface access by introducing multiple virtual eSIM ports (eSIM ports 1, 2, 3, etc.), where each port can be associated with a specific profile. This allows different profiles to have dedicated access paths to the contactless interface, enabling simultaneous multi-profile support while maintaining profile-specific access control.
Solution Approach 2:
The patent introduces a contactless interface manager as an intermediary component that handles routing between the contactless interface and multiple profiles. This manager receives requests, determines which profile should handle the request based on routing rules or user preferences, and directs the communication accordingly, enabling seamless multi-profile operation.
2Adaptability or versatility
If a single profile is restricted to the contactless interface, then contactless interactions are limited to one profile, but multiple profiles can be enabled and managed
Solution Approach 1:
The patent implements dynamic profile assignment for the contactless interface through routing rules that can be configured based on various criteria such as application type, user preferences, or operational context. The system can dynamically switch between profiles for contactless operations, ensuring that the most appropriate profile is used for each specific interaction while maintaining reliable contactless communication.
3Productivity
If multiple profiles share the same contactless interface parameters, then parameter conflicts arise, but resource utilization is improved
Solution Approach 1:
The patent applies local quality by allowing different profiles to have different parameter sets for contactless interface access. Each profile can be configured with specific parameters (such as application identifiers, routing rules, or access conditions) that are tailored to its requirements. This enables precise control over how each profile interacts with the contactless interface while avoiding parameter conflicts.

AI summary
The present invention relates to a method for controlling communication with multiplexed subscriber profiles, comprising the steps of activating a plurality of subscriber profiles, each being configured to enable mobile network communication via a first communication interface of a host terminal and to access a terminal resource of the host terminal. Activating a subscriber profile comprises determining if a parameter value of a common parameter of at least two subscriber profiles are in conflict to one another. The parameter relates to accessing the terminal resource, and resolving the parameter conflict, in response to determining a parameter value conflict.
