Telef nica Germany has selected Ericsson as main supplier to upgrade their network to support VoLTE.

Telefónica is one of the first operators in Europe that has now completed the upgrade of their network to be ready for commercial VoLTE launch. VoLTE has been deployed in all areas where Telefónica has LTE coverage in Germany.

The commercial launch will take place once Telefónica has secured the full VoLTE device eco-system for mass-market launch.

VoLTE will provide users with superior HD voice call quality, instant call-set-up, and allow simultaneous usage of superfast LTE data services during calls. Ericsson's SRVCC (Single Radio Voice Call Continuity) functionality enables seamless handover of ongoing voice calls from LTE to circuit-switched 3G and 2G networks.

The contract scope includes: Ericsson IMS (IP Multimedia Subsystem) products: CSCF (Call Session Control Function), MTAS (Multimedia Telephony Application Server), MRS (Media Resource System) and System Integration Services for Telefónica's multivendor network. The services provided include deployment and end-to-end design and verification, as well as fault analysis.

Karsten Schröder, Head of Converged Solutions, Telefónica Germany: "When we started six years ago with the investment into IMS to deliver DSL voice services, we laid the seed for a strategic modernization of our core service architecture. With the advent of VoLTE, we were able to harvest the fruits by re-using the very same IMS core for our mobile customers, being the first operator proving that VoLTE is not just a standard, but can be used in a real-life multi-vendor environment. As a result, the convergent architecture allows us today to deliver seamless services agnostic to the physical access by which the customer is connected to our network."
