Core-Network Mobile Data Troubleshooting With Automated Analysis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for troubleshooting cellular data issues at user equipment (UE) are inconvenient, time-consuming, and resource-intensive for both users and service providers, often requiring manual intervention and extensive network searches, which may not fully resolve the issues.
Innovation Solution
A troubleshooting system in the core network that automates data issue resolution by performing quick and deep analyses based on subscription usage and network status data, generating analysis messages for the UE, and creating incident tickets for further verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual troubleshooting steps are performed by the user (restarting device, contacting customer care), then the data issue may be resolved, but the process is inconvenient, time-consuming, and resource-intensive
Solution Approach 1:
The system performs preliminary troubleshooting actions automatically by analyzing subscription usage data and network status data before the user completes manual steps. The core network retrieves and analyzes relevant data, generates quick analysis and deep analysis messages, and provides estimated resolution times, eliminating the need for users to perform time-consuming manual troubleshooting steps
Solution Approach 2:
The system enables self-service troubleshooting by automatically analyzing data and generating diagnostic messages without requiring user intervention beyond initiating the troubleshooting process. The core network autonomously retrieves subscription usage data, analyzes network status, and communicates findings to the user equipment, allowing the system to service itself rather than requiring extensive user action
2Measurement precision
If comprehensive troubleshooting analysis is performed by the service provider, then accurate diagnosis is achieved, but it requires extensive network searches and manual intervention
Solution Approach 1:
The troubleshooting process is segmented into distinct phases: quick analysis (retrieving subscription usage data) and deep analysis (retrieving network status data). Each phase focuses on specific data sources and generates targeted messages, reducing the complexity of performing comprehensive analysis while maintaining diagnostic accuracy through structured, modular information gathering
3Speed
If the system performs quick analysis using subscription usage data, then rapid initial diagnosis is provided, but detailed network status analysis requires additional time
Solution Approach 1:
The system performs quick analysis first using readily available subscription usage data to provide rapid initial diagnosis and estimated resolution times. This preliminary action delivers immediate value to the user while the system concurrently or subsequently performs deeper network status analysis, structuring the process to provide fast initial feedback without sacrificing comprehensive diagnostic capability
Data Source
AI summary
A troubleshooting system is configured to receive, from an unstructured supplementary service data (USSD) gateway (USSD-GW) in the core network, an instruction based on a USSD message indicating that a user equipment (UE) is experiencing a data issue, transmit, to the UE, a quick analysis message in response to the subscription usage data indicating that the data issue is related to the data usage and the subscription plan of the UE, transmit, to the UE, a deep analysis message in response to the network status data indicating that the data issue is related to the radio access network or the core network, and transmit, to a network operations center, a ticket describing the data issue occurring at the UE, wherein the ticket comprises at least a portion of the subscription usage data or the network status data.
