Multi-Tier Signal Encryption for Wireless Billing Consolidation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users of wireless communication devices, particularly those utilizing GSM networks, face challenges with multiple SIM cards requiring separate billing accounts, leading to higher airtime rates and cumbersome management due to the inability to consolidate airtime usage across devices.
Innovation Solution
A multi-tier signal encryption mechanism is implemented, where a secondary wireless communication device provides keys and ciphering algorithms to a primary device, allowing for secure signal transmission and consolidation of billing across multiple devices under a single account, using a common secondary signal encryption mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple SIM cards are used in wireless communication devices, then each device can operate independently with its own billing account, but the subscriber must manage multiple billing accounts and pay higher collective airtime rates
Solution Approach 1:
The patent merges the signal encryption functions of multiple SIM cards into a single SIM card. The primary SIM card provides authentication and key generation, while the secondary SIM card provides ciphering algorithms. This combination allows multiple wireless devices to share a single billing account, eliminating the need to manage multiple billing statements while maintaining secure communication for each device.
Solution Approach 2:
The patent makes a single SIM card universal by enabling it to serve multiple wireless devices simultaneously. The SIM card contains both authentication credentials and signal encryption capabilities that can be shared across different devices, allowing the subscriber to consolidate billing while maintaining device independence.
2Reliability
If multiple SIM cards are used for each wireless device, then each device has dedicated encryption credentials, but obtaining and managing multiple SIM cards is time-consuming and cumbersome
Solution Approach 1:
The patent combines the functions of multiple SIM cards into a single SIM card that can serve multiple devices. Instead of acquiring separate SIM cards for each device, the subscriber obtains one SIM card that provides authentication and encryption services to all devices, significantly reducing the time and effort required for SIM card management.
Solution Approach 2:
The patent creates a virtual copy of the SIM card's encryption functionality across multiple devices. The primary SIM card generates authentication credentials, and these credentials are securely distributed to multiple devices, allowing each device to have dedicated encryption capabilities without requiring physical SIM card copies.
3Ease of operation
If separate billing accounts are used for each SIM card, then each device can be billed independently, but the collective airtime rates are higher than a single consolidated plan
Solution Approach 1:
The patent merges multiple billing accounts into a single billing account associated with one SIM card. By consolidating airtime usage from multiple devices under a single account, the subscriber qualifies for lower bulk airtime rates while still maintaining the ability to track and manage usage by individual devices through the single billing statement.
Data Source
AI summary
One or more systems and methods are disclosed to provide secure transmission of signals by a primary wireless communication device that utilizes a secure multi-tier signal encryption mechanism. A secondary signal encryption mechanism of a secondary wireless communication device generates an intermediary algorithmic output required in the encryption processing at a primary signal encryption mechanism of a primary wireless communication device. In one embodiment, the secondary signal encryption mechanism comprises a subscriber identity module (SIM) card. In one embodiment, wireless signal transmission occurs over a GSM/GPRS/EDGE network.
