Azimuth Announces VoLTE Support for Industry Leading Analytics and Automation Solution

Azimuth Systems, Inc., a leader in mobile performance test solutions, today announced the addition of unique VoLTE support to their integrated analytics and automation toolset, DNA and DAC. VoLTE is one of the most challenging milestones in the ubiquitous adoption of LTE whereby voice and video can be sent over LTE’s packet-based network while leveraging its substantial QoS and policy framework capabilities. VoLTE will no longer require bandwidth to be separately allocated for circuit switched traffic; it will instead allow operators to share capacity for voice, video and data. VoLTE is thus expected to be a key element in operators’ LTE-based plans to offer high quality of service to consumers and monetize their investments with differentiated offerings.

Azimuth’s DAC and DNA solution for VoLTE delivers detailed per call as well as aggregated analytics and reporting for VoLTE deployments. Seamless integration of the DAC and DNA products ensures that Azimuth’s solution for VoLTE provides rapid and effective test and analysis of VoLTE performance. This is essential in both deployment and post-deployment phases of VoLTE, to meet the quality expectations users have of a 4G service.

Azimuth DAC and DNA toolset is Azimuth’s platform for advanced VoLTE support. Device Automation & Control (DAC) enables unattended execution of user experience testing and logging for smartphones and other mobile devices. Device-Network Analytics (DNA) provides KPIs and analytics that enable device benchmarking and profiling, linking subscriber perceived performance to underlying device-network interaction and root cause analysis for both voice and video performance

Azimuth DAC and DNA for VoLTE is unique in that it:


Is the ONLY solution in the industry that intelligently ties the VoLTE SIP, RTP layer performance with the underlying LTE device-network interaction

Unlike other solutions that show events across multiple layers as individual/disjointed events, DNA leverages advanced algorithms to synchronize events from different layers to provide a unified view that connects user performance to the underlying device-network interaction.

Can profile and analyze performance on a per call basis and across multiple calls.

Performance is typically reported for a statistically significant number of samples, however, common statistical analysis tools could underestimate the impact of outliers (VoLTE, unlike data, is very unforgiving). Integration of DAC automation allows for immensely valuable control, logging and analytics at a very granular level.

Was developed hand in hand with a leading operator and an OEM.

This has played a critical role in ensuring that the designed capabilities directly address the biggest points of pain, and key operator/OEM use cases.

Nandish Chalishazar, Director & Head of Engineering - Analytics Business Unit, commented, “We’re extremely excited to bring advanced VoLTE support to our DAC and DNA solution. Joint development with multiple ecosystem partners has ensured that DAC and DNA for VoLTE provide rapid as well as deep insights into device and network issues that may not otherwise be easily understood. DAC and DNA for testing, analyzing and improving VoLTE performance should be an essential tool in any VoLTE toolbox.”

DAC and DNA for VoLTE builds upon Azimuth’s DAC and DNA foundation. That core solution already provides:


Consolidated set of optimal KPIs needed to understand device-network performance issues and debug them

Not only does this make it easier and faster to get to the root cause, it also makes the tool effective for field teams that may not have the time to analyze reports in detail.

Benchmarking and Regression of Devices.

While most tools in the industry are built as stand-alone post processing tools, DNA was integrated from the ground up with automation (DAC) that allows us not only to derive the analytics, but also to run the tests in a synchronized fashion across devices. This powerful capability allows synchronized execution of applications on devices with the same environmental conditions enabling a full apples-to-apples performance comparison for both single data connections as well as for multiple simultaneous data connections.

Focused set of test cases optimized to catch key issues.

While most solutions try to achieve greater test coverage through a comprehensive set of test cases (100s of test cases), DAC and DNA enables the user to more effectively extract and analyze data from a smaller set of tests, providing deeper insight with a much smaller test plan. DAC and DNA thus provide enhanced results much faster than is possible with other current tools.

Ability to aggregate data from multiple sources

Synthesizes a holistic view of the events; provides visibility into events/behaviors that wouldn’t have been obvious with narrow independent views of the individual data.

VoLTE will be a key element in many operators and OEMs growth plans; effective test, measurement and analysis tools will be essential to its success. Azimuth DAC and DNA for VoLTE, designed to offer breakthrough VoLTE performance insights, is the latest addition to Azimuth’s growing portfolio of analytics and automation solutions and can benefit the VoLTE ecosystem of operators, OEMs, infra vendors and chipset vendors in the development, deployment and ongoing benchmarking of VoLTE solutions.
