There are three networking methods for 5g private network: 1. Virtual private network, which is implemented in the operator's network using slicing technology; 2. Independent private network, which is a 5G network independently constructed by enterprises. Including independent wireless, bearer, and core networks, this private network is completely isolated from the operator's network; 3. Hybrid private network is a compromise between virtual private network and independent private network, and some network functions use the operator's equipment , some network functions are exclusive to enterprises.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The 5th Generation Mobile Communication Technology (5G for short) is a new generation of broadband mobile communication technology with the characteristics of high speed, low latency and large connections. 5G communication facilities are the key to realizing the realization of human, machine and physical objects. Internet network infrastructure.
5G Network is the fifth generation mobile communication network. Its peak theoretical transmission speed can reach 20Gbps, which is 2.5GB per second, which is more than 10 times faster than the transmission speed of 4G network. For example, a 1G movie can be downloaded in 4 seconds. With the birth of 5G technology, the era of using smart terminals to share 3D movies, games and ultra-high-definition (UHD) programs is coming to us.
Three networking methods of 5g private network
1. Virtual private network: This kind of private network is provided by the operator In the network, slicing technology is used to implement wireless slicing, bearer network slicing, and core network slicing to form a logically independent network, called a virtual private network. This kind of private network is characterized by fast deployment, low cost, and poor security. Virtual private networks are generally operated and maintained by operators themselves.
2. Independent private network: This private network is a 5G network independently constructed by the enterprise, including independent wireless, bearer, and core networks. This private network is completely isolated from the operator's network. This kind of private network is characterized by slow deployment, high cost, good security, and high operation and maintenance requirements. Independent private networks are operated and maintained by the enterprise itself or by the operator.
3. Hybrid private network: This kind of private network is a compromise between the above two private networks, which means that some network functions use the operator's equipment, while some network functions are exclusive to the enterprise. For example: the control plane network function of the private network uses the operator's equipment, while the user plane of the private network is dedicated to the enterprise. The bearer network can be partly constructed by operators and partly by enterprises. Deployed to the enterprise side through the user plane, the security of user data can be ensured, and the data does not leave the enterprise campus. This hybrid private network is characterized by moderate deployment speed, relatively low cost, high data plane security, and low control plane security. Hybrid private network operation and maintenance generally requires operators and enterprises to operate and maintain their own equipment separately.
Expand knowledge: Private network communication
Private network communication refers to the provision of services for government, public security, public utilities, industry and commerce, etc. Emergency communications, command and dispatch, daily work communications and other services. It refers to the communication network built within some industries, departments or units to meet their needs for organizational management, safety production, dispatching and command, etc.
The private network wireless communication system can be divided into the following three levels:
Terminal layer: handheld terminals used by end users, vehicle-mounted terminals, and data collection and uploaded data transmission terminals, etc., access the system through the air interface provided by the system layer to achieve communication.
System layer: including wireless access base stations, core switching centers and other external gateway equipment. The system layer completes the terminal’s air interface access, call signaling processing, voice codecs and services It provides data (voice, SMS) routing and switching functions, and communicates with the external network through external gateway equipment. In addition, the system layer also provides a rich application layer interface so that application layer equipment can be configured based on the system layer based on actual customer scenarios and needs. Secondary development work.
Application layer: There are application layer interfaces based on the system layer and application devices developed according to user application scenarios. Typical application layer devices include dispatch consoles, recording equipment, GIS, etc.
