Open Wireless Architecture (OWA) Virtualization System for Wireless Mobile Terminal Device

An Open Wireless Architecture (OWA) Virtualization System for Wireless Mobile Terminal Devices is a comprehensive framework designed to enhance the flexibility, openness, and performance of mobile devices. This system comprises several key components that work together to create a virtualized layer between the physical transmission layer and the user applications/operating systems.

?

KEY COMPONENTS

?

OWA Baseband Processing Sub-Layer

?

This sub-layer supports open baseband processing for various existing and future Radio Transmission Technologies (RTTs) using Open Interface Parameters (OIP) and baseband management systems. It allows for flexible and efficient processing of different wireless standards.

?

Wireless Adaptation and Virtualization Sub-Layer

?

This component maps RTT-specific baseband signals from both Principal and Supplemental RTTs into Open Baseband Signals and OIP for the OWA Baseband Processing Sub-Layer, and vice versa. It adapts data rates, bandwidth, timing, and control between different RTTs.

?

OWA BIOS Interface and Framework

?

The OWA BIOS manages system I/O architecture, interface definitions, controls, and system initialization for the OWA wireless mobile terminal system platform. It provides a foundation for the entire system's operation.

?

Software Defined Module (SDM)

?

SDM defines Portable Air-Interface Modules based on the OWA wireless mobile terminal system platform. This allows for flexible changes in RTTs or wireless standards through an external memory card or standards module.

?

Host OS Interface

?

This interface connects to the Home and Principal operating system of the wireless mobile terminal device. Users can reconfigure the Principal OS with different operating systems as needed.

?

Visitor OS Interface

?

The Visitor OS Interface connects to Supplemental, Foreign, or Visitor operating systems, allowing new or visiting applications to run.

?

Virtual Machine Manager

?

This component manages the mapping and monitoring of the virtual machine system between the Visitor OS and Host OS. It supports seamless handover and switching between different operating systems.

?

Open OS BIOS

?

The Open OS BIOS multiplexes and schedules the Principal OS and Supplemental OS, while providing an open OS API for the user's application layer.

?

BENEFITS AND IMPLICATIONS

?

The OWA Virtualization System offers several advantages:

?

Flexibility: It allows mobile devices to support multiple RTTs and operating systems concurrently.

Openness: The system ensures independence and openness in both architecture and operations.

Efficiency: It optimizes wireless mobile terminal system performance and maximizes wireless spectrum utilization efficiency.

Future-proofing: The system can adapt to new wireless standards and operating systems without requiring hardware changes.

Seamless operation: Users can operate across different OS and RTT platforms seamlessly.

?

By implementing this virtualization layer, mobile devices can become more versatile, supporting various applications across different operating systems and wireless standards. This approach addresses the limitations of single-OS platforms like Android, which may struggle to support the rapidly increasing number of mobile applications globally in the long term.

?

The OWA Virtualization System represents a significant step towards creating truly open and flexible mobile devices that can adapt to changing technologies and user needs.
