Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current VoLTE call troubleshooting in LTE networks lacks end-to-end visibility across multiple network devices, particularly when devices from different vendors are involved, making it difficult and costly to identify and resolve performance issues.
Innovation Solution
A system and method that collect performance information from various network devices in the LTE, EPC, IMS, and PDN networks, correlate this information, and generate an end-to-end VoLTE call record, enabling unified troubleshooting across devices from different vendors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If performance information is collected from multiple network devices from different vendors, then end-to-end troubleshooting capability is improved, but system complexity and implementation difficulty increase
Solution Approach 1:
The patent segments the complex multi-vendor troubleshooting problem into individual device-level performance information collection units. Each network device generates standardized performance information independently, which is then aggregated to form complete end-to-end call records. This segmentation allows each device to be handled uniformly regardless of vendor, reducing overall system complexity.
Solution Approach 2:
The patent implements a universal performance information collection mechanism that works across multiple vendors and device types. By defining standardized performance information parameters and collection methods that are vendor-agnostic, the system achieves multi-functionality where the same approach can troubleshoot calls across diverse network infrastructure from different manufacturers.
2Measurement precision
If detailed performance information is collected from all network devices, then measurement precision of call quality is improved, but loss of time for data processing increases
Solution Approach 1:
The patent applies preliminary action by having network devices generate and store performance information continuously during normal operation, before troubleshooting is needed. When a call quality issue arises, the pre-collected performance information is already available for immediate analysis, eliminating the need for time-consuming data collection during incident response.
Solution Approach 2:
The patent replaces manual or reactive troubleshooting mechanisms with an automated system that continuously collects and correlates performance information. This automated mechanical system processes data systematically without human intervention, reducing both the precision of measurement and the time loss compared to manual analysis methods.
3Adaptability or versatility
If end-to-end call records are generated across multiple vendors' devices, then adaptability of troubleshooting system is improved, but difficulty of detecting and measuring performance issues increases
Solution Approach 1:
The patent applies homogeneity by standardizing performance information parameters across all vendor devices. By ensuring that performance data from different vendors follows uniform formats, definitions, and collection methods, the system achieves consistent detectability and measurability across the entire multi-vendor network infrastructure.
Solution Approach 2:
The patent introduces an intermediary correlation mechanism that bridges performance information from different vendors. This intermediary layer standardizes and correlates data from various sources, making performance issue detection and measurement easier by providing a unified view rather than dealing with heterogeneous vendor-specific formats directly.
Data Source
AI summary
A device receives information associated with a voice-over-long term evolution (VoLTE) call from multiple network devices that handle the VoLTE call and that are provided in an evolved packet system (EPS). The device identifies particular parameters from the information associated with the VoLTE call, and combines the particular parameters into an end-to-end call record for the VoLTE call. The device outputs or stores the end-to-end call record for the VoLTE call.
