Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional radio access technologies require separate controllers and radios for different protocols like 5G and Wi-Fi, leading to increased costs and difficulties in maintaining quality of service, especially during data transfer between these technologies.
Innovation Solution
A converged enterprise wireless access platform using Open RAN architecture integrates licensed cellular and unlicensed Wi-Fi technologies into a single radio network with a single controller, employing software-based signal processing and AI for analytics and spectrum management across both licensed and unlicensed bands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate controllers are used for different radio access technologies (5G, Wi-Fi), then each technology can be independently managed, but system complexity and cost increase
Solution Approach 1:
The patent merges multiple radio access technology controllers (5G NR, Wi-Fi) into a single converged radio access network controller. The controller includes multiple processing subsystems, each capable of handling different RAT protocols simultaneously, thereby reducing the number of separate controllers while maintaining technology-specific management capabilities.
Solution Approach 2:
The radio access network controller is designed as a universal platform that can handle multiple radio access technologies through configurable processing subsystems. Each subsystem can be dynamically allocated to different RATs based on network requirements, enabling one controller to perform multiple functions that previously required separate dedicated controllers.
2Reliability
If separate controllers are used for different radio access technologies, then technology-specific optimization is possible, but Quality of Service maintenance becomes difficult during data transfer
Solution Approach 1:
The converged controller acts as an intermediary that receives data transfer requests and determines the appropriate processing subsystem to handle the transfer. When data needs to move between different RATs, the controller mediates the transfer by routing it through the appropriate subsystems, ensuring QoS requirements are met while maintaining technology-specific optimization.
Solution Approach 2:
The controller dynamically allocates and configures processing subsystems based on real-time network conditions and QoS requirements. This dynamic capability allows the system to adapt to changing data transfer demands between different RATs, maintaining optimal performance and QoS without requiring separate static controllers for each technology.
3Reliability
If multiple separate controllers are deployed, then each can be optimized for its specific protocol, but overall system cost increases
Solution Approach 1:
The patent combines multiple protocol-optimized controllers into a single multi-functional controller that maintains protocol-specific processing capabilities through separate processing subsystems. This merging reduces the total number of physical controllers while preserving the benefits of protocol optimization through software-based processing.
Solution Approach 2:
The controller is designed as a universal platform with configurable processing subsystems that can be optimized for different protocols. This multi-functionality allows a single controller to replace multiple specialized controllers, reducing quantity while maintaining protocol optimization through flexible resource allocation.
