Empirix Debuts VoLTE Service Assurance Solution

By Craig Galbraith Comments

MOBILE WORLD CONGRESS — Bedford, Mass.-based Empirix has introducted the Empirix E-XMS service-assurance solution for monitoring Voice over LTE (VoLTE) from end-to-end. Empirix says E-XMS enables operators to assure next-generation LTE services and gain complete visibility into quality of experience as communications switch among mobile, 3G and wireline environments. 

Empirix says the unique, holistic view of the network makes it possible to preempt issues and resolve problems before they impact customers.

Unlike traditional IP communications, operators have multiple deployment options for VoLTE.  Many are looking to reduce costs by migrating voice services to the VoIP/IMS core. When LTE conditions change, these customers are routed to other parts of the network mid-call. Other operators are choosing to send calls directly to circuit switched networks as soon as voice service is requested.

“LTE networks were originally the solution to handle increased data traffic, but with the growing presence of LTE devices, and the accompanying demand for voice services over the network, operators saw the need for a standardized approach," said Rob Bamforth, principal analyst, Quocirca. “Regardless of the method implemented, VoLTE promises better call quality and more flexible services, like simultaneous voice and data, though there are a number of challenges that mobile operators will need to overcome, particularly related to finding and resolving issues before they can impact the end-user. This requires a deep visibility into the network that has not previously been available."

Empirix says the E-XMS Service Assurance Platform mitigates the network management challenges associated with mobile and fixed line convergence including handoffs and fallback scenarios. It collects, correlates and analyzes data across heterogeneous environments to provide an end-to-end view of customer experience, application performance, service quality, network health and interoperability.

The solution is fully integrated with the Empirix architecture for technology management which features pre-deployment testing to preempt issues, comprehensive monitoring to assure that solutions perform at peak levels and analytics that predict new ways of delighting customers and creating revenue.

Empirix announced the E-XMS in conjunction with Mobile World Congress in Barcelona.
