Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for providing communication profiles for electronic subscriber identification modules (eSIMs) in mobile communication devices are inefficient, as they rely on generic profiles that do not account for device-specific capabilities and requirements, leading to suboptimal communication performance.
Innovation Solution
A system where eSIMs are assigned device-specific communication profiles based on device classes, with a profile server and data server working together to determine the device class of a mobile communication device from its electronic identification (eID) and provide the corresponding communication profile, which includes specific capabilities such as data rates and error rates, through a wireless communication interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If generic communication profiles are used for all eSIMs, then the system is simple and easy to operate, but communication performance is suboptimal and does not account for device-specific capabilities
Solution Approach 1:
The patent applies local quality by providing customized communication profiles tailored to specific device classes rather than using a single generic profile for all devices. Each device class receives profiles optimized for its specific capabilities and requirements, thereby improving communication performance without requiring complex manual configuration by users.
Solution Approach 2:
The system implements self-service through automated device class determination and profile assignment. The profile server automatically determines the device class based on the electronic identification and assigns the appropriate communication profile without user intervention, maintaining operational simplicity while enabling optimized profiles.
2Productivity
If device-specific communication profiles are implemented, then communication performance is optimized for specific device capabilities, but the profile server complexity increases
Solution Approach 1:
The patent applies parameter changes by determining device class based on electronic identification parameters and using these parameters to select appropriate communication profiles. The system changes profile parameters (data rates, error rates, connection frequencies) according to the determined device class, thereby optimizing productivity while managing server complexity through systematic parameter-based selection.
Solution Approach 2:
The patent introduces an intermediary mechanism by using the electronic identification as a key to determine device class and subsequently select the appropriate profile. This intermediary approach (eID → device class → profile) simplifies the overall system architecture by creating a clear decision pathway that manages profile server complexity while enabling device-specific optimization.
3Measurement precision
If device class determination is performed by querying a data server, then accurate device-specific profiles can be assigned, but communication delay increases
Solution Approach 1:
The patent applies preliminary action by pre-organizing communication profiles according to device classes in the profile server's memory. When a device connects, the system quickly determines the device class and immediately retrieves the pre-prepared profile, avoiding time-consuming real-time analysis or complex queries. This preliminary organization reduces profile assignment delay while maintaining accurate device class identification.
