Ericsson, Vodafone deploy cloud-based VoLTE and Wi-Fi calling in the Netherlands


Ericsson and Vodafone Netherlands have deployed the country’s first cloud-based and fully virtualized Voice over LTE (VoLTE) and Wi-Fi calling solution.

Wi-Fi calling enables operator voice services to be provided in more locations, such as indoor environments like basements, by complementing macro network coverage.

VoLTE offers fast call set-up times and high-definition (HD) voice quality while facilitating a broader range of IP-based communication capabilities, such as video calling over LTE and multi-device support.


As a result of the deployment, Vodafone Netherlands can now provide a superior experience for users of mobile video communication services compared with similar services delivered over internet access.

The solution is based on a commercial Network Functions Virtualization (NFV) deployment of Ericsson IP Multimedia Subsystem (IMS) and Ericsson Evolved Packet Core (EPC). The complete cloud-based solution also includes Virtual Network Functions (VNF) for Wi-Fi calling, policy control and application server domain.

Matthias Sauder, Head of Networks, Vodafone Netherlands, says: “Network virtualization brings huge opportunities for efficiency and agility. It will allow us to introduce new services more rapidly to our subscribers. We are very pleased with Ericsson’s support in deploying NFV in our network in the Netherlands, which will now enable swift launches of new IP-based communication services for our customers.”

Valter D’Avino, Head of Western and Central Europe, Ericsson, says: “Ericsson has deployed a VoLTE and Wi-Fi calling system that can automatically scale within a telecom cloud and fulfill telecom-grade service availability. It provides Vodafone with a complete solution to evolve their voice and SMS business toward an all-IP communications network based in the cloud”.

“This is a great example of how operators everywhere can leverage cloud and virtualization technologies to explore new business opportunities.”

The unique end-to-end VoLTE and Wi-fi calling overlay network includes VNFs for the Ericsson IP Multimedia Subsystem with Ericsson Multimedia Telephony Application Server, Ericsson Call Session Control Function, Ericsson Evolved Packet Core with Ericsson Evolved Packet Gateway, Ericsson Wi-Fi Mobility Gateway and other Ericsson control and authentication functions.
