Network Offloading via Access Point State Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network offloading methods fail to provide a better Quality of Service (QoS) for terminals accessing WLAN, leading to degraded user experience due to inaccurate determination of data offloading needs based solely on load or interference information of the currently used network.
Innovation Solution
A method for network offloading that considers access point state information, including usage ratio, load, and interference, to determine whether a terminal can access a WLAN, ensuring accurate offloading decisions and improved QoS by reducing network interference or load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data offloading is performed based only on load or interference information of the currently used network, then the offloading decision process is simple, but the accuracy of offloading decisions is poor and QoS service cannot be improved
Solution Approach 1:
The patent introduces access point state information as an intermediary element between the terminal and the network. This intermediary provides additional dimensions of information (usage ratio, load, interference) that mediate the offloading decision process, enabling more accurate assessments without significantly increasing system complexity.
Solution Approach 2:
The patent implements a feedback mechanism where access point state information is continuously collected and fed back to the base station. This feedback loop enables dynamic adjustment of offloading decisions based on real-time network conditions, improving decision accuracy while maintaining manageable process complexity.
2Measurement precision
If access point state information is collected and considered in offloading decisions, then the accuracy of offloading decisions and QoS service are improved, but the complexity of the offloading process increases
Solution Approach 1:
The patent applies preliminary action by pre-collecting and organizing access point state information before the actual offloading decision is made. The base station gathers usage ratio, load, and interference information in advance, so that when offloading decisions are needed, the information is already prepared and structured, reducing the complexity of real-time decision-making.
3Reliability
If the base station determines whether the terminal is allowed to access WLAN based on comprehensive access point state information, then the QoS service for data transmission is improved, but the determination process becomes more complex
Solution Approach 1:
The patent segments the determination process into distinct evaluation dimensions: usage ratio assessment, load assessment, and interference assessment. Each dimension is evaluated separately using specific criteria, and the results are combined to make the final offloading decision. This segmentation makes the complex determination process more manageable and systematic.
