Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in flexibly providing personalized communication functions for user equipment due to restrictions imposed by mobile network operators, making it difficult to adapt communication profiles across different devices.
Innovation Solution
A method for user equipment that includes determining if a communication profile is associated with the user, sending a request to a server for support information to obtain a profile if needed, and installing or deleting profiles based on memory availability, using eSIM technology with secure authentication and management modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If communication profiles are manually configured for each user device, then security is improved, but adaptability and ease of operation deteriorate due to operator restrictions
Solution Approach 1:
The system enables self-service by allowing user devices to automatically obtain and configure communication profiles through the backend system without manual intervention. The device sends a first request including identification information, the backend retrieves the appropriate profile, and automatically configures it on the device, eliminating the need for manual security configuration while maintaining security through automated authentication and profile management
Solution Approach 2:
A backend system acts as an intermediary between mobile network operators and user devices. This intermediary manages communication profiles centrally, receiving requests from devices, retrieving appropriate profiles from operators, and delivering them to devices. This mediator enables adaptability across different operators and devices while maintaining security through centralized control and authentication mechanisms
2Ease of operation
If communication profiles are automatically downloaded from remote servers, then ease of operation is improved, but device complexity increases due to additional authentication and management modules
Solution Approach 1:
The patent extracts complex authentication and profile management functionality from the user device and places it in an external backend system. The device only needs to send simple identification information and receive profiles, while the backend handles the complex tasks of authentication, profile retrieval from operators, and secure delivery. This extraction reduces device complexity while maintaining ease of operation for users
Solution Approach 2:
The backend system serves multiple functions: it acts as an authentication server, profile repository, communication interface with mobile network operators, and profile delivery mechanism. This universal platform handles diverse profile types from different operators through a single interface, reducing the need for multiple specialized components in individual devices while maintaining ease of operation
3Adaptability or versatility
If multiple communication profiles are stored in user equipment, then adaptability is improved, but loss of substance increases due to memory consumption
Solution Approach 1:
Communication profiles are pre-configured and stored in the backend system before being needed by user devices. When a device needs a profile, it is automatically retrieved and delivered in advance of actual use. This preliminary preparation in the backend eliminates the need for devices to permanently store multiple profiles, providing adaptability on demand while minimizing memory consumption in constrained device environments

AI summary
The present disclosure relates to a method of providing a communication function in a user equipment, comprising: receiving, at the user equipment, a login request to log the user in to the user equipment; determining, by the user equipment, based on the login, whether the user equipment has a communication profile associated with the user; if it is determined that the user equipment has a communication profile associated with the user, enabling the stored communication profile; if it is determined that the user equipment does not have a communication profile associated with the user stored: sending, by the user equipment, a first request to a first server to request support information for obtaining a communication profile associated with the user; receiving, at the user equipment, the support information from the first server; and obtaining, by the user equipment, the communication profile from the first server or a second server based on the support information.
