Software-Defined Radio Chipset for Multi-Network Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile devices are limited to operating on a single service provider's network technology, such as GSM or CDMA, due to hardware and software constraints, preventing seamless switching between competing technologies and requiring physical changes in SIM cards, which is cumbersome and does not allow operation on different network technologies.
Innovation Solution
A mobile device equipped with a software-defined radio chipset module stores software builds and provisioning data for multiple service providers in non-volatile memory, enabling it to communicate on various networks and switch between them by loading appropriate software builds and parameters, while preventing conflicts through a connection manager tracker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mobile devices store provisioning data for a single service provider, then the device can operate reliably on that provider's network, but the device cannot operate on multiple service provider networks including different technology types
Solution Approach 1:
The mobile device is designed with a universal architecture that can support multiple service provider networks and communication technologies (GSM, CDMA, and future technologies). The device stores multiple software builds and provisioning data sets in non-volatile memory, allowing it to function on different network types without requiring separate devices. This multi-functionality enables a single device to replace what would traditionally require multiple specialized devices.
Solution Approach 2:
The device dynamically changes its operational parameters by loading different software builds and provisioning data sets corresponding to different service providers. When switching between service providers, the device modifies its configuration parameters, communication protocols, and software environment to match the target network's requirements. This parameter transformation allows seamless adaptation from one network type to another.
2Ease of operation
If a user wants to switch between service providers on a conventional mobile device, then the user can maintain service continuity, but the user must physically interchange SIM cards which is cumbersome and time-consuming
Solution Approach 1:
The patent replaces the mechanical SIM card interchange system with a software-based switching mechanism. Instead of physically removing and inserting SIM cards, the user can switch between service providers through software commands that load the appropriate provisioning data and software build from non-volatile memory. This substitution eliminates the mechanical manipulation required for SIM card changes and enables instant switching.
Solution Approach 2:
Multiple software builds and provisioning data sets are pre-loaded into the device's non-volatile memory before the user needs to switch service providers. This preliminary preparation allows the device to have all necessary service provider configurations readily available, eliminating the need for physical SIM card insertion during the switching moment. The user simply activates the desired service provider from the pre-loaded options.
3Adaptability or versatility
If a mobile device is equipped with hardware to operate on GSM networks, then the device can communicate on GSM networks, but the device cannot operate on CDMA networks due to fundamental hardware differences
Solution Approach 1:
The device incorporates a universal radio chipset that can support multiple communication technologies including GSM, CDMA, and future network types. This single hardware platform replaces what would traditionally require separate dedicated hardware for each network technology. The universal chipset, combined with software-defined radio capabilities, allows the device to adapt its physical layer operations to match different network requirements through software configuration rather than hardware changes.
Solution Approach 2:
The device employs dynamic reconfiguration of its radio hardware through software control. The radio chipset can change its operational characteristics, modulation schemes, and coding methods based on the loaded software build and the target network type. This dynamic adaptability allows the same physical hardware to function across different communication technologies by continuously adjusting its parameters rather than requiring fixed hardware configurations for each technology.
