###### Abstract  
This paper proposes a virtualized network function orchestration system based on Network Function Virtualization (NFV), one of the main technologies in 5G mobile networks. This system should provide connectivity between network devices and be able to create flexible network function and distribution. This system focuses more on access networks. By experimenting with various scenarios of user service established and activated in a network, we examine whether rapid adoption of new service is possible and whether network resources can be managed efficiently. The proposed method is based on Bluetooth transfer technology and mesh networking to provide automatic connections between network machines and on a Docker flat form, which is a container virtualization technology for setting and managing key functions. Additionally, the system includes a clustering and recovery measure regarding network function based on the Docker platform. We will briefly introduce the QR code perceived service as a user service to examine the proposal and based on this given service, we evaluate the function of the proposal and present analysis. Through the proposed approach, container relocation has been implemented according to a network device's CPU usage and we confirm successful service through function evaluation on a real test bed. We estimate QR code recognition speed as the amount of network equipment is gradually increased, improving user service and confirm that the speed of recognition is increased as the assigned number of network devices is increased by the user service. 5G mobile network; wireless mesh networks; Better Approach to Mobile Ad hoc Networking (BATMAN); network orchestration system; network virtualization technology; virtual network function +

About the second issue--the low latency and the cloud-based network services, technologies for the datacenters of the IT companies, such as Google and Amazon, are deployed into the Telco's mobile networks. The cloud computing of the IT companies enables the hardware and software separation in Telco's networks, which means the traditional hardware product-oriented network architecture changes to the function-oriented flexible network architecture. By using cloud computing technologies, telecom companies can enable the access and core networking functionalities at the optimal place with dynamically managed capacity. This idea changed the fundamental of the mobile networks and the 5G uses these concepts as the underlying principle for the future network design. The 5G network is based on virtualization different from the original network system. It is based on software-defined networking (SDN) and network function virtualization (NFV). In particular, NFV technology enables networks to be maintained in a cost-efficient way by replacing previously necessary physical appliances with virtualized environments. 5G networks applying this technology have the advantage of comprising flexible networks by arranging virtualized network function (VNF), which is virtualized according to the user's requirement. However, to apply NFV technology, IT virtualization and cloud technology is needed and to apply this technology, equipment with high specifications is required. This can result in difficulties in usability outside the cases of communications enterprises or data center management corporations [5]. So, various researchers have been conducted on the topic of cost-optimal design of 5G virtualized networks recently [6; 7; 8; 9].
