Multi-radio Interface for Wireless Device Application Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE and emerging 5G networks, face challenges in efficiently managing and separating safety-critical and non-safety critical applications across multiple radio computers within a single device, which is essential for ensuring reliability and security in applications like remote surgery or industrial automation.
Innovation Solution
The implementation of a generalized multiradio interface (gMURI) that allows for the independent operation of multiple radio computers, each with its own radio operating system, enabling the separation of safety-critical and non-safety critical applications by using a unified radio application interface and radio control framework, and allowing for secure data exchange between a communication services layer and the radio computers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple radio computers share a common interface and operating system, then device complexity is reduced and resource utilization is improved, but safety-critical and non-safety critical applications may interfere with each other, compromising reliability
Solution Approach 1:
The patent divides the radio communication system into multiple independent radio computers (first radio computer for safety-critical applications, second radio computer for non-safety critical applications). Each radio computer has its own operating system instance and runs independently, preventing interference between safety-critical and non-safety critical applications while maintaining separate execution environments and resource management.
Solution Approach 2:
The patent implements a universal multi-radio interface (MURI) that can serve multiple radio computers with different functionality requirements. The MURI provides common communication services and protocols while supporting both safety-critical and non-safety critical radio functions, reducing overall system complexity despite having multiple radio computers.
2Reliability
If safety-critical and non-safety critical applications run on separate radio computers, then interference is prevented and reliability is improved, but system complexity and resource requirements increase
Solution Approach 1:
The patent segments the application runtime environment by providing separate operating system instances for safety-critical and non-safety critical applications. Each radio computer operates independently with its own OS, ensuring that failures or interference in non-safety critical applications do not affect safety-critical operations.
Solution Approach 2:
The patent combines multiple radio computers under a unified multi-radio interface framework that provides common services, protocols, and resource management. This merging approach allows independent radio computers to cooperate efficiently and share infrastructure resources, reducing overall system complexity.
3Ease of operation
If a unified interface is used for multiple radio computers, then ease of operation and resource sharing are improved, but the ability to guarantee safety-critical performance is reduced
Solution Approach 1:
The multi-radio interface is designed as a universal framework that can serve multiple radio computers with different performance requirements. It provides common communication services and protocols while being configurable to support both safety-critical real-time requirements and non-safety critical best-effort services.
Solution Approach 2:
The interface architecture applies different service quality levels to different radio computers based on their requirements. Safety-critical radio computers receive guaranteed performance and deterministic service, while non-safety critical radio computers receive best-effort service, allowing the unified interface to accommodate diverse performance needs.

AI summary
Apparatuses, systems, and methods for software reconfiguration of a multi-radio wireless device that includes multiple radio computers. A wireless device may be configured to associate a first application with a first radio computer and a second application with a second radio computer. The second application may perform a different function than the first application. The UE may be configured to exchange, via a multiradio interface, data between a communication services layer of the wireless device and the first and second radio computers. In some instances, the first application may be a safety related application and/or a safety critical related application and the second application may be a non-safety related application and/or a non-safety critical application.
