Ericsson Demos VoLTE in Virtualized Core

Ericsson has demonstrated VoLTE in a virtualized core-network environment.

Specifically, a large European operator was invited to the Ericsson Eurolab in Aachen, Germany in early June to experience the first proof-of-concept demonstration of Ericsson’s VoLTE (Voice over LTE) solution in a virtualized core-network environment. The VoLTE solution was shown for the first time in a virtualized telecom-core-network environment, and was run on commercial Ericsson IMS equipment, including the Call Session Control Function (CSCF), the Multimedia Telephony Application Server (MTAS), and Ericsson Enriched Messaging. Commercial VoLTE/LTE smartphones were used in the demonstration.

Ericsson said the operator benefits from this approach could include easily scalable hardware infrastructure and the speedier launch of new communication services over IP.

The company has repeated the demo for other operator representatives.

Marton Sabli, Head of IMS Control and Media Plane, Product Line IMS, Business Unit Networks, says: “Ericsson demonstrated for the first time that a VoLTE system can automatically scale within a telecommunication cloud and fulfill telecom-grade service availability. This availability – 99.999 percent uptime over a year – is achieved with a combination of a high-availability, telecom-grade cluster on application level and cloud mechanisms, such as hot migration.”
