ZTE, HP and China Unicom test NFV-based VoLTE technology

ZTE, Hewlett-Packard and China Unicom have demonstrated the feasibility of network function virtualisation (NFV) based voice over long-term evolution (VoLTE) services.

The proof of concept project used a range of vEPC (virtualised evolved packet core) and vIMS (virtualised IP multimedia subsystem) equipment and solutions provided by ZTE to test 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.
