Location-Aware RAT Prioritization for Mobile Network Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile devices often default to a specific Radio Access Technology (RAT) without considering the best quality of experience in a particular geographic location, leading to suboptimal network performance.
Innovation Solution
Mobile devices and networks dynamically prioritize RATs based on geographic location, bandwidth, and device capabilities to ensure connection to the RAT that provides the best quality of experience, using onboard lookup tables, measurement reports, and network configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If mobile devices default to a specific RAT, then device operation is simplified, but network performance and user experience deteriorate
Solution Approach 1:
The patent implements dynamic RAT prioritization where the default RAT is not fixed but changes based on geographic location, network conditions, and device capabilities. The system continuously adapts the RAT selection priorities through measurement reports and network feedback, transforming a static default mechanism into a dynamic optimization system that balances ease of operation with network performance.
Solution Approach 2:
The patent changes the parameter of RAT priority ordering based on multiple factors including geographic location, available bandwidth, latency requirements, and device capabilities. By modifying these parameters dynamically, the system achieves optimal network performance without requiring complex manual intervention from users.
2Adaptability or versatility
If devices support multiple RATs, then adaptability improves, but device complexity increases
Solution Approach 1:
The patent implements self-service RAT selection where the mobile device automatically manages its own RAT prioritization based on pre-configured preferences, geographic location, and network conditions. The device autonomously generates measurement reports, evaluates available RATs, and adjusts connections without requiring complex user configuration or manual control.
Solution Approach 2:
The patent performs preliminary configuration of RAT priorities and preferences before actual connection decisions are needed. Devices are pre-configured with RAT capability information and preference settings that are stored and referenced during connection decisions, eliminating the need for complex real-time calculations and reducing operational complexity.
3Ease of operation
If network provides static RAT configuration, then ease of operation improves, but adaptability to geographic location deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where mobile devices continuously report network conditions, measurement data, and connection quality to the network operator. This feedback loop enables the network to dynamically adjust RAT priorities and configurations based on actual performance and geographic location, maintaining both simplicity for users and adaptability for the system.
Solution Approach 2:
The patent transforms static network configurations into dynamic, location-aware configurations. The system automatically adapts RAT priorities based on real-time geographic location data and network conditions, allowing the network to respond to changing environments without requiring complex user configuration or manual intervention.
Data Source
AI summary
A mobile device determines the radio access technology (RAT) to use to connect to a wireless network at a geographic location based on determining the highest priority RAT that the mobile device is compatible with in the geographic location. The highest priority RAT in the geographic location is, for example, the RAT with the largest aggregate bandwidth or the RAT with the best user quality of experience in the geographic location. The mobile device can determine the highest priority RAT based on band and bandwidth information at the geographic location or the wireless network can determine the highest priority RAT based on band and bandwidth or measurement reports received from mobile devices in the geographic location.
