# Improvement of 5G Transportation Services with SDN-Based Security Solutions and beyond 5G
## 3 A Framework of 5G Transportation
### Modeling Framework for Self-Driving  
Although modeling network traffic is expected to have the above properties, basic MA based on SDN enhances access to the management of network traffic. In this research, a modeling framework for a 5G transportation service (F5 TS) allows the users to handle self-driving vehicles with minimum operational functionalities. Further, the measurement of the F5 TS allows service providers to handle and manage the dynamic network traffic. In the proposed framework, the following modules offer the necessary functionalities of SDN-based MA and enhance the transportation services. These are SDN-based MA functionalities and network configurations. Figure 3 shows the management issues of transportation services and infrastructures. A transportation system depends on excellent management, which deals with the priority of emergency services, handling data traffic (small, medium, and large data packets) during vehicular communication, and minimizing energy consumption. This model can handle real-time data traffic, such as the data traffic from vehicular communication. Furthermore, priority users (\(\mathbf{P_{u}}\)), load users (\(\mathbf{L_{u}}\)), energy users (\(\mathbf{E_{u}}\)) and security users (\(\mathbf{S_{u}}\)) are examples of the management issues considered in the transportation system. These issues rely on the excellent services and infrastructure of the 5G transportation system. Here, the process of network traffic management depends on the traffic management protocols and the functions of SDN, and the preference of users' conditions and demands.  
In this FSTS, accessing functionalities provide some additional management facilities such as prioritization and intelligent systems. The focus of FSTS is to improve the flexibility and availability of services facilities with maximum security. The complexity of infrastructure defined within the 5G-based transportation system can also be simplified in FSTS. Simultaneously accessing many transportation services is not easy when the number of users within the square kilometers increases. However, FSTS improves the performance of a transportation service using the low-complex infrastructure of 5G networks and protocols. A data transmission protocol between users or service providers or users and service providers depends on the flow and modeling of network traffic. Hence, modeling network traffic with SDN-based MA needs to be considered in 5G environments. In this model, the following properties enhanced the network traffic flow according to the users' wishes:  
1. Accessing multiple flows of traffic. Provided by the MA protocols and algorithms regarding the data traffic management.
2. Priority of traffic. By increasing the configuration features, different versions of orthogonal multiple access (OMA) and non-orthogonal multiple access (NOMA) schemes allow us to configure the priority of the traffic.
3. Dynamic traffic. All real-time transmissions depend on the dynamic traffic, which needs to be programmed dynamically using SDN concepts to analyze the quality and quantity of the traffic.
4. Intelligent traffic. Using the SDN controller and its programmable approach, intelligent traffic minimizes energy consumption and increases energy efficiency. Intelligent transport system using a software-defined network (SDN). An intelligent transport system using SDN enhances the control of the automation programmability functions when users need more services. Transport service providers also update the services securely with multiple SDN controllers. Further, SDN-based 5G+ technology allows the service providers to handle multiple services with minimum energy cost.
