Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently managing and integrating multiple Radio Access Technologies (RATs) for optimal resource allocation, load balancing, and traffic steering across heterogeneous networks.
Innovation Solution
A centralized RAT controller system is introduced to coordinate and manage multiple RATs, including cellular and WLAN networks, by collecting measurement information from RAT communication managers to determine traffic steering instructions and optimize resource utilization across different networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a centralized RAT controller system is introduced to coordinate and manage multiple RATs, then network efficiency and resource allocation are improved, but device complexity and system architecture complexity increase
Solution Approach 1:
A centralized RAT controller is introduced as an intermediary component that coordinates between multiple RAT communication managers and the core network. This mediator collects measurement information from various RATs, makes centralized traffic steering decisions, and manages load balancing across heterogeneous networks, thereby improving overall network efficiency while isolating the complexity within a dedicated control entity
Solution Approach 2:
The RAT controller is designed as a universal management entity that handles multiple functions including traffic steering, load balancing, measurement collection, and coordination across different RATs (cellular and WLAN). This multi-functional approach consolidates various management tasks into a single system, improving productivity while managing complexity through functional integration
2Measurement precision
If measurement information is collected from multiple RAT communication managers, then traffic steering accuracy and resource management are improved, but information processing complexity and communication overhead increase
Solution Approach 1:
Measurement information from multiple RAT communication managers is merged and consolidated at the centralized RAT controller. This combining approach allows comprehensive network state assessment for accurate traffic steering decisions while processing aggregated data rather than handling separate information streams, thereby improving measurement precision without proportionally increasing processing complexity
Solution Approach 2:
The system implements feedback mechanisms where measurement information flows from RAT communication managers to the RAT controller, which then generates traffic steering decisions that are fed back to the communication managers. This closed-loop feedback enables accurate and adaptive traffic steering based on real-time network conditions while maintaining structured information flow to manage processing complexity

AI summary
Some demonstrative embodiments include devices, systems and/or methods of controlling Radio Access Technology (RAT) communication managers. For example, a RAT controller may communicate with a plurality of RAT communication managers to receive measurement information from one or more of the RAT communication managers, and, based on the measurement information, to send traffic steering information to at least one RAT communication manager.
