ZTE has launched the world's first virtualised Cloud NF (network function) solution for multi-RAT (radio access technology) networks.
The evolution of mobile networks to flat, cloud-based networks will improve operator competitiveness and simplify operations, administration and management (OAM). In response to this trend, ZTE has developed the Cloud NF solution, which integrates the functions of core networks and controllers through network functions virtualisation (NFV).
The Cloud NF solution uses virtualisation technology to separate hardware from software in the architecture and integrates all network element functions of the mobile network. In addition, it applies the software-defined networking (SDN) concept to separate the gateway forwarding function from the core network, which improves forwarding efficiency.
In collaboration with Intel, ZTE has used a common Intel® architecture hardware platform to build the entire system. ZTE is one of the leading developers of software for wireless system solutions provided by Intel. Through the use of this software, the ZTE Cloud NF solution achieves outstanding performance.
Mr. Liu Jianhua, CEO of ZTE’s Core Network Product Line, said: “We are glad to work with Intel on technology innovation and the Cloud NF system, an industry-leading virtualisation solution. Our architecture provides an efficient solution for deploying multi-mode 2G/3G/4G multi-layer networks; and enables the smooth transition from legacy networks through to 5G networks.”
The ZTE Cloud NF solution has completed joint testing with a leading operator in China, during which the mobile network virtualisation solution performed very well. It will be promoted around the world in 2014, with a focus on its application in 4G networks.
