Solution Overview

Problem

Users face challenges in managing and switching cellular wireless service subscriptions across multiple wireless devices, as existing systems lack efficient methods for user-initiated and autonomous switching based on predefined criteria.

Innovation Solution

The implementation of a cellular services switching (CSS) service on each wireless device, which allows for the switching of a common cellular wireless service subscription between different wireless devices based on user-initiated triggers or autonomous criteria such as device status, proximity, and battery level.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a user subscribes to separate cellular wireless service subscriptions for each wireless device, then each device can independently access cellular services, but the user incurs increased cost and complexity in managing multiple subscriptions

Engineering Contradiction:

Improvecellular service access reliabilityVSAvoidsubscription management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple cellular service subscriptions under a single shared subscription that can be dynamically allocated across multiple wireless devices. The CSS service merges the management of what would otherwise be separate subscriptions into one unified system, allowing devices to share access to cellular services without requiring individual subscription accounts for each device.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The shared cellular service subscription is designed to serve multiple wireless devices universally, rather than being dedicated to a single device. The subscription can function across different device types and users, providing multi-functional access that reduces the need for device-specific subscriptions while maintaining reliable service access.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Ease of operation

If cellular service switching is manually initiated by users, then users have control over subscription allocation, but the switching process requires user intervention and time

Engineering Contradiction:

Improveservice switching convenienceVSAvoidswitching time

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-configuring multiple wireless devices with the necessary credentials and permissions to access the shared cellular service subscription before switching is needed. Devices are pre-registered in the system, and the CSS service is pre-installed, so when switching is triggered, the process can proceed without time-consuming setup or manual configuration steps.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The CSS service enables self-service automated switching based on predefined criteria such as device availability, signal strength, or user-defined rules. The system can autonomously determine when and how to switch the cellular service subscription between devices without requiring continuous user intervention, reducing both time loss and maintaining ease of operation through configurable automation.

Inventive Principle:

Principle #25Self-service

3Reliability

If the number of active devices accessing cellular services is limited, then network resource allocation is controlled, but device versatility and user flexibility are reduced

Engineering Contradiction:

Improvenetwork resource managementVSAvoiddevice access flexibility

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system implements dynamic device activation where the set of active devices accessing the shared cellular service subscription can change over time based on predefined criteria and conditions. Rather than maintaining a static limit on active devices, the system dynamically determines which devices should be active at any given moment, allowing flexibility in device access while maintaining controlled resource allocation through automated management.

Inventive Principle:

Principle #15Dynamics

4Productivity

If cellular service subscription information is preloaded on multiple wireless devices, then switching speed is improved, but device memory usage and initial provisioning complexity increase

Engineering Contradiction:

Improveservice switching speedVSAvoidprovisioning complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The system creates copies of the cellular service subscription information and loads them onto multiple wireless devices that may need to access the service. Rather than having each device independently subscribe to services, the subscription data is replicated across devices, enabling fast switching without requiring real-time provisioning or complex authentication processes during the switch.

Inventive Principle:

Principle #26Copying
