VoLTE – VoIP on mobile networks
ng-voice is leading in technology
With Voice over LTE (VoLTE), all speech data is forwarded paket based and prioritized through the LTE network. This allows you to save a lot of money on infrastructure as a carrier, since you don't need any 2G/3G/CDMA network components or frequencies anymore. Especially in new "green-field" roll-outs, this is a very interesting network design. These cost savings can lead into a huge competitive advantage in terms of pricing.
The VoLTE solution of ng-voice is built on top of Kamailio, which is integrated based on IMS-Standard into mobile networks. Kamailio is the leading Open-Source SIP-Server and is continously improved and kept up-to-date. ng-voice is integrating this IMS-compliant platform as a Carrier Grade Solution into LTE networks of any size. The hardware is run on basic Linux Servers or energy saving embedded systems, which can, for example, be used as a distributed Proxy-CSCF.
Our Founder, Carsten Bock, started the IMS-Integration into Kamailio based on the Open IMS-Core by the Fraunhofer Institute. He is coordinating and promoting the efforts within the open-source community until today.
Only T-Mobile and Verizon in the U.S. and Singtel in Singapore have launched VoLTE deployments in production based on proprietary solutions based of the big infrastructure vendors. In 2014 the first VoLTE networks will be launched in South Africa and Bulgaria, based on the open-source solutions of ng-voice. More networks in Singapore, Dubai and Hongkong will likely follow in 2015, these networks will also be based on our open-source components. The move of Kamailio into mobile networks is unique!
Almost every handset vendor has devices with an integrated SIP/VoLTE stack available, even though they are not publicly available for the "normal user".
With the global transition to 4G LTE, the broad-based adoption of all-IP technologies has paved the way for the convergence of Telco and IT worlds. NFV establishes a framework for mobile operators to deploy 4G LTE solutions, such as Voice over LTE (VoLTE), Rich Communication Services (RCS) and Mobile Core Networks, in virtualized data centers and to fundamentally change the cost equation for building and managing next generation networks.
NFV is a framework for implementing multiple software applications on a common general purpose computing platform, where resources are flexibly shared on demand or as scheduled, thus providing significant CAPEX/OPEX savings. NFV employs a software model for implementing network solutions, thus providing service agility and deployment flexibility that cannot be achieved based on a hardware model.
Virtualization is the underlying technology to NFV, which is a logical stepping stone from traditional hardware-based deployment models to NFV. The transformation is from tradition hardware-based deployment models, to software-based, and ultimately to cloud-based, i.e. NFV. By deploying virtualized solutions today, operators have the opportunity to gain valuable experience in the technology and processes related to virtualization, while reaping the benefits of improved service agility, deployment flexibility and reduced CAPEX.
