Home Network Quality Determination via Carrier KPI Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The difficulty in accurately analyzing home network quality due to the high cost and long period required for deploying probes on various types of user terminals, making it challenging to determine the cause of deteriorated user experience in video services.
Innovation Solution
A method and apparatus that use a collection device in the carrier network to determine network quality by comparing parameter values collected within the carrier network with baseline thresholds, eliminating the need for probes on user terminals and allowing for real-time analysis of home network quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If probes are deployed on terminals of all users in the entire network, then network quality can be accurately analyzed, but deployment cost and time increase significantly
Solution Approach 1:
The patent extracts the network quality measurement function from individual user terminals and consolidates it at the network operator side. Instead of deploying probes on each terminal, the operator collects network KPI parameters from the carrier network and uses them to determine home network quality, thereby eliminating the need for large quantities of terminal probes while maintaining accurate network quality analysis capability
Solution Approach 2:
The patent introduces network KPI parameters as an intermediary between the carrier network and home network quality assessment. These parameters serve as mediators that allow the operator to infer home network quality conditions without direct terminal probe deployment, resolving the contradiction between measurement accuracy and probe quantity
2Measurement precision
If probes are deployed on terminals of all users in the entire network, then network quality can be accurately analyzed, but deployment complexity increases
Solution Approach 1:
The patent extracts the measurement function from complex terminal environments and relocates it to the simplified operator network side. By collecting network KPI parameters from the carrier network rather than deploying probes on diverse terminal types, the system maintains measurement accuracy while dramatically reducing deployment complexity and compatibility requirements
Solution Approach 2:
The patent creates a universal measurement approach that works across all user terminals without requiring terminal-specific probe deployments. The network KPI parameters collected from the carrier network serve multiple measurement purposes for different users and services, eliminating the need for customized probe solutions for each terminal type
3Measurement precision
If probes are deployed on terminals of all users in the entire network, then network quality can be accurately analyzed, but deployment time increases
Solution Approach 1:
The patent extracts the quality measurement capability from the terminal deployment process and implements it at the network operator side using existing carrier network infrastructure. This allows immediate collection of network KPI parameters without the time-consuming process of deploying and configuring probes on numerous user terminals, achieving fast network quality analysis

AI summary
A network quality determining method includes, when experience quality represented by a customer experience index of a target user within a first time period is lower than experience quality represented by a customer experience index threshold, determining, using a first parameter value that is of a network key performance indicator (KPI) parameter of the target user within a second time period and that is collected by a collection device in a carrier network, a second parameter value of the network KPI parameter of the target user within the second time period in a home network, and when network quality represented by the second parameter value of the network KPI parameter is lower than network quality represented by a first threshold corresponding to the network KPI parameter in the home network, determining that quality of the home network is poor.
