MADRID -- Telefónica has become the first network operator to demonstrate a breakthrough new technology that transfers telephone calls from an LTE network to a 3G mobile network seamlessly and without interruption. This handover was achieved in Germany in a test laboratory environment that accurately simulates that of a real mobile network. Voice over LTE (VoLTE) moves the transmission of voice traffic off older networks designed primarily for voice and onto a data-only network. The voice call is broken into data bits and transmitted across the network in a similar way that an e-mail or MP3 song would move across the Internet, and guarantees the broadband needed for the best quality. VoLTE technology is much more efficient than traditional wireless voice services, allowing clearer calls and numerous other superfast services. "Telefónica has achieved a significant landmark with the successful testing of this mobile broadband network for the future,” said Enrique Blanco, CTO of Telefónica. “Most importantly, however, is our ability to deliver the very best customer experience – which is at the core to our long-term network strategy. With VoLTE, our customers will be seamlessly connected to a superfast intelligent network that not only gives a top quality voice service – but also a network that opens up a new world of opportunities, such as high definition video calls". Telefónica Deutschland is the first network provider in the world to demonstrate handover of LTE calls to 3G using SRVCC, with components from several different suppliers, corresponding to actual conditions in today's mobile communication networks. Handsets and network components from at least six different manufacturers have been used, including Acme Packet, Ericsson, Huawei, NSN, Qualcomm and Sony Mobile. Telefónica SA
