Russia's MTS Tests VoLTE Using Nokia Equipment
Published on: 12th May 2014
Russia's MTS has completed the first Voice over LTE (VoLTE) call on a telco cloud infrastructure based on equipment supplied by Nokia.
The virtualization 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, including its IP Multimedia Subsystem (IMS), Telephony Application Server (TAS) and Home Subscriber Server (HSS). The company's Cloud Application Manager provided automated deployment and management of all cloud applications. Nokia's Professional Services for VoLTE helped the operator ready the architecture and design of its network to enable multi-vendor integration and core migration, while specialized project management ensured high-quality project delivery.
