Solution Overview

Problem

Wireless communication devices face disruptions in communication services when remote SIMs become unavailable due to disruptions in logical or wireless carrier connections, leading to inadequate service provision to connected devices.

Innovation Solution

A method is introduced to select and manage subscriber identity modules (SIMs) by establishing a starter wireless carrier connection using a local SIM, then authenticating with a SIM bank to select and switch between local and remote SIMs to maintain communication services, ensuring continuity through multiple connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single remote SIM is used to establish wireless carrier connections, then the device complexity is reduced, but the reliability of communication services deteriorates when the SIM becomes unavailable

Engineering Contradiction:

Improvecommunication service continuityVSAvoidSIM management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple SIM cards (local and remote) into a unified communication system where the wireless communication device can selectively use any available SIM to maintain service continuity. This merging approach ensures that if one SIM becomes unavailable, another can take over, thus improving reliability without significantly increasing complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The system dynamically selects and switches between different SIM cards based on their availability and operational status. The wireless communication device monitors the state of multiple SIMs and automatically transitions to an alternative SIM when needed, providing adaptive reliability without requiring complex manual configuration.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple SIM cards are managed manually for location changes and data quota replenishment, then the adaptability to different networks is improved, but the ease of operation deteriorates

Engineering Contradiction:

Improvenetwork compatibilityVSAvoidSIM switching operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The wireless communication device automatically performs SIM selection and switching operations without requiring user intervention. The system monitors network conditions, SIM status, and service requirements to autonomously determine which SIM to use, thereby maintaining high adaptability while eliminating manual operational complexity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system continuously monitors the operational status of multiple SIM cards and network conditions, using this feedback to automatically adjust SIM selection. This feedback mechanism ensures optimal network compatibility while simplifying operation, as the device self-corrects based on real-time conditions without user input.

Inventive Principle:

Principle #23Feedback

3Ease of operation

If remote SIMs are used to avoid physical SIM swaps, then the ease of operation is improved, but the reliability deteriorates when logical data connections are disrupted

Engineering Contradiction:

ImproveSIM replacement operationVSAvoidservice availability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system maintains multiple SIM cards (both local and remote) as backup options before any disruption occurs. By having pre-configured alternative SIMs ready, the system cushions against potential connection disruptions, ensuring that service availability is maintained even when logical data connections to remote SIMs are interrupted.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent introduces local SIM cards as intermediary backup options when remote SIM connections are disrupted. These local SIMs serve as mediators that can take over communication services when the primary remote SIM becomes unavailable due to connection issues, thus maintaining reliability while preserving the ease of operation benefits of remote SIM management.

Inventive Principle:

Principle #24Intermediary (Mediator)

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.
