ZTE Corporation, a major international provider of telecommunications, ent erprise and consumer technology solutions for the Mobile Internet, today announced the successful completion of a joint project with Hewlett-Packard and China Unicom to demonstrate the feasibility of network function virtualisation (NFV) based voice over long-term evolution (VoLTE) services.
The proof of concept (PoC) project involved a comprehensive range of vEPC and vIMS equipment and solutions provided by ZTE to be used when testing for end-to-end VoLTE services in virtualised environment deployment solutions. This included interoperability of management and orchestration (MANO) functions and interfaces, virtualised network function (VNF) lifecycle management, VNF disaster recovery and maintenance management, VoLTE end-to-end functionality and performance, data plane acceleration and packet domain gateway functions of C/F separation.
To comply with the European Telecommunications Standards Institute (ETSI) reference architecture, the project was completed using HP’s C7000 Blade server, and a virtualised infrastructure manager (VIM) provided by ZTE and HP. The project was also implemented using ZTE’s vEPC, vIMS, VNF Manager and element management system (EMS) solutions, in addition to a network function virtualisation (NFV) orchestrator provided by HP and ZTE.
ZTE is committed to development of NFV and cloud-based network technologies, cooperating with operators and technology providers around the world with PoC projects. To date, ZTE’s virtualised core network solutions are deployed across five commercial and 28 trial projects globally.
