CENX, Spirent Demo Orchestration of VoLTE in Virtualized Environment

By Paula Bernier February 25, 2015

CENX has partnered with Spirent to demonstration orchestration of voice over LTE services on virtualized network infrastructure.

A software-defined networking service orchestration company, CENX sells a solution called the Cortx Service Orchestrator. It gives service providers like the telcos visibility of network utilization, performance metrics, and service topology so they can manage quality of service.

Spirent, meanwhile, is a network test company. It sells a product called Spirent Landslide for end-to-end testing of mobile networks. And it can deliver perceptual objective listening quality assessment measurement of voice calls.

VoLTE, according to the companies, has to date been deployed commercially by 14 operators in 7 countries.

T-Mobile says it was the first major national U.S. carrier to launch nationwide VoLTE in July 2014. AT&T in May of last year introduced VoLTE to its first markets. Hong Kong Telecom the same day announced its launch of VoLTE. About a month later, T-Mobile went live with VoLTE in 15 markets.

Doug Mohney, editor in chief of HD Voice News, and a TMC contributor, says: “VoLTE is the last necessary piece before carriers start shutting down the legacy mess of 2G and 3G networks and refarming spectrum. Guaranteed quality of service is the edge VoLTE offers over OTT best effort solutions, along with the fallback ubiquitous voice solution when people disagree on what OTT clients they want to use.”

Industry analyst Jeff Kagan adds that VoLTE and HD voice will start to grow and play a larger and more important role in the wireless industry going forward.

While VoLTE is now arriving, it’s taken a long time to implement VoLTE due to its huge technical complexity, the need for excellent LTE radio coverage and enough backhaul, the need for devices supporting VoLTE, and the lack of a clear business model around this technology, among other issues, says Dean Bubley, director and founder of London-based research and consulting firm Disruptive Analysis.
