Empirix Offers VoLTE Service Assurance


Empirix Inc. this month is making generally available the voice over LTE (News - Alert) service assurance solution it announced last week at Mobile World Congress.


The solution, called Empirix (News - Alert) E-XMS, does end-to-end VoLTE monitoring. That’s important, Neil McKinlay, product manager of mobile solutions, tells TMCnet, because with VoLTE we’ll see a plethora of IMS implementations. With all that variation and all the applications out there, he adds, it will be hard to test all the possibilities for LTE traffic. So having the visibility that E-XMS provides both throughout the network and into applications will be important to do service assurance, he says.

McKinlay says that if presence, for example, is adversely impacting VoLTE, the E-XMS can identify that, providing the carrier with actionable intelligence they can use to deliver superior performance. The goal, he adds, is to improve service providers’ “mean time to understanding”

“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,” says Rob Bamforth, principal analyst at 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, which was founded in 1992 and is based in Bedford, Mass., provides service assurance solutions to both enterprise and service provider customers. Its enterprise customers include Apple, Bank of America, and VISA. Its service provider customers include BT, Comcast, Cox, Verizon FiOS (News - Alert), WIND.
