Huawei and China Mobile have successfully demonstrated a virtualised voice-over-Long Term Evolution (VoLTE) solution, designed to support the operator’s ‘Cloudified’ VoLTE service. The demonstration is part of the onoing partnership between the vendor and China Mobile, and ‘reinforces the…vision of network functions virtualisation (NFV) as the next generation core network architecture’, a statement from Huawei noted. The Cloudified VoLTE solution used the Chinese vendor’s off-the-shelf hardware servers and cloud operating system and the demonstration featured NFV-based core network elements, including a virtualised IP Multimedia Subsystem (vIMS), a virtualised evolved packet core (vEPC), a virtualised subscriber data management (vSDM) and a virtualised policy and charging rules function (vPCRF).
A press release from Huawei elaborated on the demonstration: ‘The acceleration of cloud technology development has resulted in carriers moving away from traditional service architecture unable to provide a satisfactory user experience, to an ICT integrated cloud architecture. NFV will change the closed circle of the traditional telecom network, shorten service innovation period, reduce operation and maintenance costs, and establish a more open industrial chain.’
