Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless service providers face challenges in efficiently managing user device connections across multiple radio access networks (RANs) due to network congestion, device capabilities, and application requirements, leading to suboptimal performance and resource inefficiencies.
Innovation Solution
A system and method utilizing a RAN Handover Server (RHS) to analyze user device and network conditions, determining the optimal RAN for user device connections based on factors like network congestion, device capabilities, subscription information, and invoked applications, and instructing the device to hand over connections between RANs to optimize performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user device connects to multiple different wireless technologies through multiple RANs, then technology versatility and service options are improved, but network congestion and resource management complexity increase
Solution Approach 1:
The patent introduces a network controller as an intermediary entity that manages and coordinates connections between user devices and multiple RANs. This mediator handles the complexity of managing multiple wireless technologies by centralizing control, making handover decisions, and optimizing resource allocation across different RANs, thereby resolving the contradiction between technology versatility and management complexity
Solution Approach 2:
The patent dynamically changes network parameters such as handover thresholds, connection priorities, and resource allocation based on real-time network conditions, device capabilities, and service requirements. This allows the system to adaptively manage multiple wireless technologies by adjusting parameters to optimize performance while reducing management overhead
2Reliability
If the system optimizes handover decisions based on multiple factors (network congestion, device capabilities, application requirements), then connection performance is improved, but the complexity of decision-making and processing increases
Solution Approach 1:
The patent segments the complex handover decision-making process into distinct modules or criteria evaluations (e.g., network condition assessment, device capability matching, application requirement analysis). Each segment handles a specific aspect of the decision, making the overall complex process more manageable and efficient while maintaining high connection performance
Solution Approach 2:
The system performs preliminary assessments and preparations for handover decisions by pre-evaluating network conditions, device capabilities, and service requirements before actual handover is needed. This advance preparation reduces the complexity of real-time decision-making while ensuring optimal connection performance

AI summary
A system may be configured to identify that a user device is connected to a first radio access network (“RAN”), via a first technology; and to identify that the user device is capable of accessing a second RAN, via a second technology. The system may further be configured to instruct the user device to concurrently connect to the second RAN and the first RAN, send or receive a first type of traffic via the first RAN, and send or receive a second type of traffic via the second RAN.
