Virtual SIM Profile Transfer for Battery Conservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual SIM systems lack flexibility in allowing temporary transfer of SIM profiles between devices, especially when the primary device is low on battery or unavailable, leading to limitations in continuous service usage and efficient battery conservation.
Innovation Solution
A method and system for temporarily provisioning a virtual SIM profile from a primary device to a target device, enabling continued functionality without draining the primary device's battery, by suspending the SIM profile on the primary device and activating it on the target device, with features like authorization processes, data transfer, and session management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a virtual SIM profile is transferred to another device, then service continuity is maintained when the primary device is unavailable, but system complexity increases due to profile management across multiple devices
Solution Approach 1:
The patent creates a copy of the virtual SIM profile from the primary device to a target device, allowing the profile to be used on multiple devices simultaneously. This copying mechanism enables service continuity when the primary device is unavailable while managing complexity through automated profile replication rather than manual reconfiguration.
Solution Approach 2:
The patent introduces a profile management system that acts as an intermediary between devices, automatically handling profile transfer, activation, and deactivation. This mediator manages the complexity of multi-device profile coordination, allowing seamless service continuity without requiring users to manually manage profiles across devices.
2Adaptability or versatility
If SIM functionality is shared between devices through connection, then multi-device access is enabled, but service availability is limited when the primary device is off or disconnected
Solution Approach 1:
The patent performs preliminary actions by pre-transferring and activating the virtual SIM profile on the target device before the primary device becomes unavailable. This ensures that when the primary device is off or disconnected, the target device already has the active profile and can immediately provide service without requiring connection to the primary device.
Solution Approach 2:
The patent segments the SIM profile functionality from the primary device, allowing it to operate independently on the target device. This segmentation enables the virtual SIM to function autonomously on the target device without requiring the primary device to be online or connected, thus improving service availability while maintaining multi-device access.
3Ease of operation
If devices use separate SIMs with common mobile number, then individual device functionality is maintained, but data plan management becomes complex requiring separate plans
Solution Approach 1:
The patent merges the data plan management functionality with the virtual SIM profile, allowing a single data plan to be associated with the profile regardless of which device it's active on. This combining of plan management with the transferable profile eliminates the need for separate data plans on each device while maintaining individual device functionality through profile-based access.

AI summary
Systems and methods are described for temporarily provisioning a virtual SIM profile at a target device. A virtual SIM profile is received at a target device. A temporary virtual SIM use session of the virtual SIM profile is initiated at the target device. The virtual SIM profile is managed at the target device by disabling use of the virtual SIM profile at the target device in response to receiving an indication to end the temporary virtual SIM use session.
