VoLTE demoed in virtualized core-network environment

Ericsson has demonstrated VoLTE in a virtualized core-network environment, bringing telecom-grade cloud-enabled services a step closer to commercialization. Operator benefits include easily scalable hardware infrastructure and the speedier launch of new communication services over IP.

Innovation has become a vital ingredient in bringing the Networked Society vision to life. It is Ericsson’s ambition to shift up a gear when it comes to innovation; to turn ideas into business more quickly, and support operators in launching new services faster.

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.

Demonstrations of related parts of this technology were also shown during Ericsson Innovation Day at the Eurolab in Aachen on June 18, where around 90 operator representatives and many business partners came to experience business creation, the latest technology and innovation trends.

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.

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."

Virtualization enables operators to reduce the needed computing capacity and balance the capacity need from different applications. With the power-down functionality, computer resources can be switched off when they are not being used, which saves power and decreases the cooling needs. Virtual machines and hosts can also be quickly powered up again on demand or by the given time profile.

The VoLTE solution in a virtualized core-network environment provides a number of benefits to operators. These include:

scalable hardware to smoothly handle increasing voice traffic and new communication services running on an IMS network
cost-efficient network operations
faster time to market for new services, using common scalable hardware
the Ericsson Cloud Manager (a component of the Ericsson Cloud System), which can support power off at low usage enabling energy savings
