Enhanced cloud based mobile core network with network function virtualization

Abstract

The mobile technology is improved by adopt the Internet Protocol (IP) based technology. The IP Multimedia Subsystem or IP Multimedia Core Network Subsystem (IMS) is a technology designed by 3rd Generation Partnership Project (3GPP). This technology used IP to deliver the communication packet and recognized as Next Generation Network (NGN). The emerging IP based technology took a lot of advantages by using IP to deliver a packet. However, some issues i.e. availability, security and reliability still need consideration to meet the telecommunication standard. The cloud based computing become buzzword as a technology for cost reduction and hardware efficiencies. This paper conducted the feasibility to setup mobile core network in cloud based environment and enhanced it with network function virtualization (NFV) feature. The NFV made the network more scalable, efficient and robust network management. The QoS is presented as the results to concluded the feasibilities. The results show that cloud based mobile core network with NFV is feasible since the QoS still full fill the telecommunication standard.
