ANDSF Application Wi-Fi Offloading for QoE-Based Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting media devices to Wi-Fi networks often result in inefficient data speed usage due to random connections with lower-speed networks, leading to suboptimal utilization of available high-speed networks.
Innovation Solution
An ANDSF application is used to configure, validate, and offload user devices to wireless networks based on Quality of Experience (QoE) parameters, utilizing intelligent network services, 3GPP standard policy management, and EDGE analytics to monitor device events and manage policy pull cache, evaluation, and application.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If media devices connect to Wi-Fi networks randomly, then device complexity is reduced, but data speed utilization deteriorates
Solution Approach 1:
The media device autonomously evaluates available Wi-Fi networks based on stored policy information and automatically selects the optimal network without user intervention. The device self-determines which network to connect to based on criteria such as speed, reliability, and security, eliminating the need for manual selection while optimizing data usage.
Solution Approach 2:
Policy information about Wi-Fi networks is pre-configured and stored in the media device before actual connection is needed. This preliminary setup includes network criteria, authentication details, and selection policies that guide the automatic connection process, allowing the device to make informed decisions quickly without real-time analysis.
2Loss of time
If media devices connect to available Wi-Fi networks without evaluation, then connection time is reduced, but network selection quality deteriorates
Solution Approach 1:
Network evaluation criteria and policy information are pre-configured in the media device before connection is needed. This includes pre-stored information about network priorities, security requirements, and performance thresholds, enabling the device to quickly assess and select optimal networks without time-consuming real-time analysis.
Solution Approach 2:
The system continuously monitors network performance and connection quality, using this feedback to refine future selection decisions. Performance data from actual network usage is fed back into the policy evaluation mechanism, allowing the device to learn from past experiences and improve its network selection accuracy over time.
