Single eSIM Managing Multiple Profiles for Multi-SIM Standby

Solution Overview

Problem

Current electronic devices require multiple SIM card slots or eSIMs to achieve multi-SIM multi-standby functionality, leading to high costs and increased device size.

Innovation Solution

An electronic device with an eSIM that supports the simultaneous establishment of multiple communication connections based on different profiles stored in a single eSIM, allowing for multi-SIM multi-standby without the need for multiple SIM card slots or eSIMs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple SIM card slots or eSIMs are installed to achieve multi-SIM multi-standby, then the functionality of using multiple mobile phone numbers simultaneously is improved, but the cost and occupied space in the electronic device increase

Engineering Contradiction:

Improvemulti-SIM multi-standby functionalityVSAvoidnumber of SIM card slots or eSIMs

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple SIM card slot components into a single eSIM that can store and activate multiple profiles simultaneously. This consolidation reduces the number of physical components while maintaining multi-SIM functionality through software-based profile management.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single eSIM is designed to perform multiple functions by supporting the simultaneous activation of multiple profiles (e.g., first profile for personal use, second profile for work use). This universal design allows one component to replace what traditionally required multiple separate components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple SIM card slots or eSIMs are installed to achieve multi-SIM multi-standby, then the functionality of using multiple mobile phone numbers simultaneously is improved, but the occupied space in the electronic device increases

AI summary

A communication connection method and an electronic device are provided. The method includes establishing, by an electronic device, a first communication connection based on a first profile, where the eSIM comprises the first profile, in response to an operation of establishing a communication connection based on a second profile, establishing, by the electronic device, a second communication connection based on the second profile without terminating the first communication connection, where the first profile and the second profile are comprised in the same eSIM, and the first profile is different from the second profile.
