Virtual SIM Registration for Bluetooth Connectivity Loss
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual SIM card technology using short-range wireless communication methods, such as Bluetooth, faces challenges with signal loss and instability, leading to issues with device registration and network service availability when devices are out of range or experience interference, resulting in delayed or missed network notifications.
Innovation Solution
An electronic device with a processor and transceiver that acquires subscriber identification information from another device, registers with the network, and sends a log-off request when the connection is lost, allowing the device to re-register and maintain network connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If short-range wireless communication (Bluetooth) is used to share SIM card services between two devices, then device connectivity and service sharing are improved, but network registration reliability deteriorates when devices are out of range or experience interference
Solution Approach 1:
The patent introduces a virtual SIM card as an intermediary mechanism that decouples the physical SIM card from the second device. The virtual SIM card stores subscriber identification information and enables the second device to register with the network independently, without requiring continuous Bluetooth connection to the first device. This mediator resolves the contradiction by maintaining service sharing capability while eliminating the reliability issue caused by wireless communication interruptions.
Solution Approach 2:
The system performs preliminary action by pre-transferring subscriber identification information from the first device to the virtual SIM card in the second device before any disconnection occurs. This advance preparation ensures that when Bluetooth connection is lost, the second device already possesses the necessary credentials to maintain network registration and service access, thus preventing registration failures.
2Reliability
If the second device continuously registers with the network via Bluetooth connection to the first device, then network service availability is improved, but network service responsiveness deteriorates when connection is lost
Solution Approach 1:
The virtual SIM card acts as an intermediary that enables direct network registration for the second device without requiring continuous mediation through the first device via Bluetooth. By storing subscriber identification information locally, the virtual SIM card allows the second device to independently maintain network registration, eliminating registration delays when Bluetooth connection is lost while preserving continuous network service availability.
3Reliability
If the first device maintains continuous Bluetooth connection to provide network access, then network connectivity reliability is improved, but power consumption and system complexity increase
Solution Approach 1:
The patent extracts the network registration functionality from the first device and relocates it to the second device via the virtual SIM card. By transferring subscriber identification information to the second device, the system eliminates the need for continuous Bluetooth connection maintenance by the first device. The second device independently handles network registration and service access, significantly reducing power consumption while maintaining network connectivity reliability.

AI summary
Disclosed is a control method and electronic device, where the method includes: acquiring subscriber identification information sent by a second electronic device, where the subscriber identification information is identification information registered by the second electronic device at a network side; based on the acquired subscriber identification information, registering at the network side through a second communication connection; and detecting a connection state of a first communication connection to the second electronic device, where if the first communication connection to the second electronic device is detected to meet a first predetermined condition, sending a log-off request to the network side through the second communication connection to enable the second electronic device to perform a registration operation based on the subscriber identification information.
