Leading Russian operator MTS has completed the first Voice over LTE (VoLTE) call on a telco cloud infrastructure using Nokia’s technology.
The successful end-to-end testing, conducted in the operator’s live LTE network with user devices, gives a real-life preview of how operators can combine their offers of best voice quality and richer communication services with the most competitive and cost-effective infrastructure platforms.
The virtualisation of service and control functions in the core network is an important step in using cloud technology in the telco domain. Supported by Nokia’s commercial portfolio and a cloud management system that controls the VoLTE applications in MTS’s private telco cloud, the companies have proved the telco cloud readiness of end-to-end VoLTE.
“VoLTE and telco cloud are principal technologies that will help us address new business opportunities and deliver a superior voice experience to our customers,” said Andrey Ushatskiy, chief technical and IT officer at MTS Group. “We expect that the compound annual growth of mobile data traffic will reach 79% by 2020 and have to prepare our networks to deliver a quality mobile broadband experience to our customers.”
To enable the live VoLTE tests, MTS’s LTE radio network supplied by Nokia was complemented with telco cloud based voice core technology. The company’s Cloud Application Manager provided automated deployment and management of all cloud applications.
