Technology talk: The fast track to Voice over LTE

Nokia Siemens Networks has launched a smart approach for providing voice services over LTE networks, needing only simple and cost-effective software and hardware upgrades to existing circuit-switched core networks.

The award winning ‘Fast Track VoLTE’ provides a cost-effective way to offer Voice over LTE (VoLTE) in any mobile network.

Operators can use their existing mobile softswitching and Nokia Siemens Networks’ Mobile VoIP Server (NVS) infrastructure to manage voice traffic over the LTE network, a function that will eventually be handled by IP Multimedia Subsystem (IMS). This gives operators an important time-to-market advantage.

Fast Track VoLTE provides a transitional step between traditional networks and the all-IP world of LTE. The solution allows operators to exploit their existing circuit-switched mobile core network investments, while providing next-generation service. Investments in Fast Track VoLTE are fully re-usable when upgrading network architecture to IMS, thus reducing capital expenditure (CAPEX) in the long term.
