Solution Overview

Problem

Users face inconvenience and high costs when traveling abroad due to expensive international roaming services and the need to frequently change SIM cards, which existing solutions do not adequately address.

Innovation Solution

A method and system that pre-configures virtual SIM data on mobile terminals, allowing them to connect to mobile communication networks using pre-configured virtual SIMs, which can switch to standby mode if no unoccupied SIM card slot is available, and automatically select optimal virtual SIM numbers for communication, reducing confliction and improving user experience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If international roaming service is enabled for the SIM card, then network connectivity is achieved, but communication cost increases significantly

Engineering Contradiction:
Improvenetwork connectivityVSAvoidcommunication cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent creates a virtual SIM card that copies the functionality of a physical SIM card without requiring actual roaming SIM cards to be purchased and installed in multiple devices. The virtual SIM card stores subscriber identity data and can be deployed across multiple terminal devices, eliminating the need for users to buy expensive roaming SIM cards while maintaining network connectivity capability.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The virtual SIM card system enables a single virtual SIM card to serve multiple terminal devices (smartphones, tablets, laptops) simultaneously. This multi-functional approach allows one virtual SIM to replace multiple physical roaming SIM cards, providing universal network access across different devices without incurring separate roaming charges for each device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If multiple physical SIM cards are used for different regions, then network connectivity is ensured, but device complexity and user convenience deteriorate

Engineering Contradiction:
Improvenetwork connectivityVSAvoidSIM card management complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Instead of requiring users to physically hold and switch between multiple SIM cards for different regions, the system creates virtual copies of SIM card functionality that can be stored and managed electronically. The virtual SIM card contains the necessary subscriber data and can be deployed to multiple devices without physical manipulation, simplifying the user experience while maintaining regional network connectivity.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system pre-configures virtual SIM cards with regional network information and subscriber data before the user needs to travel. The virtual SIM cards can be pre-provisioned with appropriate MCC (mobile country code) and MNC (mobile network code) settings for different regions, so when a user travels, the correct virtual SIM is already ready to be activated without requiring physical SIM card changes.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If virtual SIM card data is pre-configured on terminals, then ease of operation improves, but the risk of data confliction between multiple terminals increases

Engineering Contradiction:
ImproveSIM card activation convenienceVSAvoiddata confliction risk
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system implements a feedback mechanism where terminal devices report their usage status and availability of SIM card slots to the virtual SIM card management server. The server uses this feedback information to determine which virtual SIM cards should be assigned to which terminals, and whether existing virtual SIM cards can be activated without causing conflicts. This continuous feedback loop enables the system to manage data consistency and prevent confliction while maintaining ease of operation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The virtual SIM card system is dynamic rather than static - virtual SIM cards can be activated, deactivated, transferred, and reconfigured based on real-time conditions. The system can dynamically adjust the assignment of virtual SIM cards to terminals based on current network conditions, device availability, and user needs, allowing the system to adapt and resolve potential conflicts before they occur while maintaining operational convenience.

Inventive Principle:
Principle #15Dynamics

AI summary

The present application relates to an information processing method and device, a computer readable storage medium and a computer device. The method comprises: acquiring a first quantity and a conflict probability, the first quantity being the quantity of mobile terminals for which virtual SIM card data is pre-configured, the conflict probability being the probability that multiple mobile terminals use the same virtual SIM card data for connection with a network at the same time; acquiring a first outbound proportion according historical data; and according to the first quantity, the conflict probability and the first outbound proportion, determining the quantity of the virtual SIM card data. According to the quantity of mobile terminals for which virtual SIM card data needs to be pre-configured, the proportion of users using the virtual SIM card data and the user conflict probability, the method can estimate the quantity of virtual SIM card data, so that the mobile terminal manufacturer can appropriately configure SIM card data according to the estimated quantity of virtual SIM card data.
