Embodiment 1

[0032] SDN is called a software-defined network. It adopts a new network architecture with centralized control. It can separate the data forwarding and logic control functions of traditional data forwarding equipment without changing the forwarding behavior of traditional IP data packets, and realize the data layer Decoupling from the control layer enables more efficient and flexible data forwarding and device management. By deploying SDN components in mobile devices and radio access network devices (RAN devices), that is, OpenFlow controllers and OpenFlow gateways, a virtual IP network can be created to efficiently organize and manage multiple wireless networks inside or around mobile devices. Access to network channels.

[0033] Today, user equipment is becoming more and more intelligent and pervasive, which makes it very easy for mobile devices to support multiple RANs. These RATs, such as GPRS, CDMA, 3G, LTE, WiMAX, Wi-Fi, etc., may be deployed simultaneously in such inte...

Embodiment 2

[0040] The above is a brief description of the SDN-5G architecture. Its structure is symmetrical and scalable. It uses multiple existing wireless network channels based on SDN technology to achieve high-speed data transmission. to combine image 3 with Figure 4 The specific process description of the network architecture, the method of using the above-mentioned 5G network architecture to transmit data, includes the following seven steps (wherein, steps 1 to 4 are the uplink transmission process, and steps 5 to 7 are the downlink transmission process):

[0041] Step 1: M-OFC determines the vIP (virtual IP), and distributes it to the upper layer application program of the mobile device through the M-OFG; specifically: before the application program of the mobile device starts communicating, the M-OFC distributes the vIP to the M -OFG, then the application program sends a vIP request to M-OFG, and M-OFG returns the corresponding vIP to M-OFG; in Mininet simulation, the host H0 ...

Abstract

The invention relates to a multichannel transmission 5G network architecture based on SDN. The 5G network architecture comprises a mobile device, a wireless access network (RAN) device and a core network, the mobile device is provided with an OpenFlow controller (M-OFC) and an OpenFlow gateway (M-OFG); the wireless access network device (RAN) is defined with an OpenFlow controller (R-OFC) and an OpenFlow gateway (R-OFG); the core network is defined with an OpenFlow controller (N-OFC) and an OpenFlow gateway (N-OFG); and flow table information is shared on a sending side and a receiving side, so that the separation and combination of data packets are matched with each other, the data transmission rate of the 5G network is greatly improved, and the network architecture effectively relieves the data flow pressure of network bearer and improves the user experience in a mobile network environment.

Description

technical field [0001] The invention belongs to the technical field of mobile communication networks, and in particular relates to a 5G network architecture based on SDN multi-channel transmission and a data transmission method. Background technique [0002] In recent years, with the rapid development of mobile Internet technology, the number of users using mobile devices has increased rapidly, and wireless network connection anytime, anywhere has gradually become a reality. However, the continuous growth of user wireless transmission requirements and the popularity of various communication applications such as the Internet of Things pose new challenges to the service support capabilities of mobile communication systems. [0003] According to Cisco's 11th annual Visual Networking Index (VNI) Global Mobile Data Traffic Forecast (2016-2021), the number of mobile phone users worldwide (5.5 billion) will exceed the number of bank account users (5.4 billion) and tap water users b...
