VoLTE & VoWifi Monitoring

Although mobile data is gaining importance, voice is still essential. A mobile number is still considered an individual’s or a business’s identity. There is still a need for a stable and a reliable real time communications service. That means, voice has taken a different shape from the legacy SS7 voice and now it has a different skin, but still a major service and income source for mobile operators. To cultivate more voice revenue, around the world, mobile operators are currently working to make VoLTE (Voice over LTE) available to as many of their subscribers.

To cultivate more voice revenue, around the world, mobile operators are currently working to make VoLTE (Voice over LTE) available to as many of their subscribers.

In order to ensure VoLTE service quality an end-to-end monitoring solution with cross-domain visibility capabilities is essential. With such solution, the health of network elements and performance of their interactions with the other entities should be monitored closely along with the voice quality, device compatibility and location specific performance issues which are crucial to guarantee and maximize the customer satisfaction.

Argela VoLTE & VoWI-FI Service Analyzer performs end-to-end, real-time correlation among 2G/3G interfaces, LTE Access, LTE Core and IMS applications, provides real-time multi-dimensional KPIs and generates correlated CDRs with first fail information classified for interfaces present.

Argela VoLTE & VoWI-FI Service Analyzer provides full control of VoLTE and VoWI-FI services by monitoring each and every related activity on the network. It correlates the collected data, which allows the observation of details of every VoLTE/VoWI-FI call in a simplified fashion. Problems are spotted with wide range of real time KPIs and are isolated easily and effectively. Detailed analysis of the problems are offered with drill down capabilities and root cause analysis. 

“Argela VoLTE & VoWI-FI Service Analyzer extracts detailed information regarding VoLTE & VoWI-FI service, collects KPIs and CDRs from the protocol probes are turns them into end-to-end correlated CDRs (for Registration, Calls and SRVCC (VoLTE only)) and KQIs, which eventually help to demonstrate the quality of VoLTE & VoWI-FI service from customers’ perspective.”

Argela VoLTE & VoWI-FI Service Analyzer offers end-to-end and multidimensional analysis of VoLTE and VoWı-FI services by monitoring LTE Access Network, WI-FI Access, and IMS Core Network. Voice User Plane quality is also evaluated via RTP/RTCP monitoring Device model and brand based quality analysis and ranking is also provided in this applications.

It offers analysis from various point of views including geographic location and network equipment for all possible interconnection types, namely, IMS-to-IMS, IMS-to-CS, IMS-to-Local-IMS, IMS-to-Other-IMS and IMS-to-Other-Network. It generates alarms and informs the operator of the performance degradations.

Argela VoLTE & VoWI-FI Service Analyzer provides detailed analysis for the VoLTE/VoWiI-FI access, Registrations, Calls and SRVCC (VoLTE only) along with fail analysis for the problematic calls, registration and SRVCC procedures.

Audio quality analysis in the VoLTE/VoWI-FI call is done by measuring the statistical and distribution information for Uplink and Downlink Mean opinion score (MOS), packet loss and jitter. 

Beyond simply looking into performance metrics for geo-locations and network equipment, operators can also benefit from insight that extends into device-level analysis. This way, issues that are isolated to particular operating systems, manufacturers, or models, can be quickly identified and addressed. Argela VoLTE & VoWI-FI Service Analyzer provides the means to analyze the VoLTE & VoWI-FI service for all device brand and models available in the market for any registration, call or other VoLTE & VoWI-FI related problems.
