Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in providing communication capabilities to all user devices due to limitations imposed by mobile network operators, leading to difficulties in enabling communication functions with reduced resources and energy consumption.
Innovation Solution
A method involving a management server that receives requests to implement communication profiles in user equipment, interacts with mobile network operators to activate these profiles, and sends activation messages to the user equipment, utilizing eSIM technology with secure digital certificates for secure embedding of subscriber information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional communication provisioning methods are used, then communication capabilities can be provided to user devices, but mobile network operator limitations prevent universal coverage and increase complexity
Solution Approach 1:
The patent introduces a management server as an intermediary between users and mobile network operators. This server handles profile management, activation requests, and coordination with multiple MNOs, thereby reducing the complexity burden from individual devices and enabling broader communication capability coverage across different networks and devices.
Solution Approach 2:
The management server provides universal profile management capabilities that work across multiple mobile network operators and various user equipment types. By creating a multi-functional platform that handles provisioning, activation, and profile distribution universally, the system overcomes MNO-specific limitations and enables broader device coverage.
2Reliability
If communication profiles are implemented in user equipment, then communication functions are enabled, but resource and energy consumption increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring communication profiles in the management server and preparing activation messages before they are needed. Profiles are created and validated in advance, and activation can be triggered remotely without requiring extensive processing or energy consumption in the user equipment at the moment of activation.
Solution Approach 2:
The patent extracts the complex profile management and activation logic from the user equipment and places it in the management server. The UE only needs to receive and apply activation messages, significantly reducing its computational burden and energy consumption while maintaining reliable communication function enablement.
3Reliability
If eSIM profiles with digital certificates are used, then security is improved, but device resources required for secure embedding increase
Solution Approach 1:
The patent implements nested security structures where digital certificates are embedded within eSIM profiles, which are in turn managed by the broader profile management system. This nested approach allows secure embedding of subscriber information in a compact manner, maintaining data confidentiality while optimizing device storage resources through hierarchical organization.

AI summary
Methods, apparatuses, and computer-readable media are described to provide a communication function in a user equipment. A first request to implement a communication profile of a user in a user equipment (UE) is received at a management server. A second request from the management server requesting an activation of the communication profile based on the first request is received at a mobile network operator (MNO). An activation message enabling an implementation of the communication profile in the UE is received at the UE.
