Remote SIM Switching for Continuous Wireless Carrier Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication devices face disruptions in communication services due to SIM card issues such as location changes, data quota exhaustion, or SIM card failures, leading to unavailable remote SIMs and disrupted connections.
Innovation Solution
Establish a starter wireless carrier connection using a starter SIM, followed by selecting a first local or remote SIM to create a first wireless carrier connection, then disconnecting the starter connection and establishing a second connection with another SIM to provide communication services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single remote SIM is used to establish wireless carrier connections, then device complexity is reduced, but reliability deteriorates due to disruptions from SIM card issues, location changes, or data quota exhaustion
Solution Approach 1:
The patent segments the SIM functionality into multiple independent SIM cards (first SIM, second SIM, third SIM) that can be independently managed and activated. Each SIM can establish separate wireless carrier connections, allowing the system to divide the communication function across multiple components to improve reliability while maintaining manageable complexity through modular architecture
Solution Approach 2:
The patent combines multiple SIM cards and wireless communication modules into a unified system where they work together to provide communication services. The wireless communication device integrates multiple SIMs and modules, merging their capabilities to ensure continuous service availability even when individual components fail or become unavailable
2Reliability
If multiple wireless communication modules are used to establish multiple wireless carrier connections, then reliability improves through redundancy, but device complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring multiple SIM cards and wireless communication modules in the device before operation. The system prepares multiple potential connection paths in advance, so when disruptions occur, alternative connections are already available and can be activated immediately without requiring complex real-time decision-making or reconfiguration
Solution Approach 2:
The patent changes the parameter of SIM card quantity from single to multiple, and wireless communication modules from single to multiple. This parameter change enables the system to establish multiple wireless carrier connections simultaneously or alternately, improving connection availability and reliability while the system manages the increased complexity through standardized protocols and automated selection mechanisms

AI summary
A method and a wireless communication device for providing communication service to devices connected to the wireless communication device. By establishing a starter wireless carrier connection using a starter SIM from a plurality of local SIMs, the wireless communication device establishes one or more logical data connections with one or more SIM banks. Remote-SIMs are selected from the one or more SIM banks and used to establish further wireless carrier connections to allow communication service to be provided to the devices over wireless carrier connections.
