One of the first things that people think of, when talking about mobile networks, is public networks. A public network is broadband network that is designed by Mobile Network Operators (MNO) to provide network services to the general public. In a public network, people choose an MNO of their choice and pay for services, which then allows people to use the network anytime, anywhere. In addition to public networks are also private networks. A private network, coined as a non-public network in 3GPP, is a type of network that is designed for typical enterprises, such as companies and schools, to provide their own services for their own purposes. In a private network, only authenticated people can access the network.

Figure 1 shows the use of a private network. The private network in Figure 1 can interwork with the public network to provide services. However, the private network is capable of providing its own network service without any interworking with the public network, depending on the customer’s request. Private networks that do not connect with the public network can provide high levels of security and closed-down services. However, pure private networks may cost more than private networks that connect to the public network, as they may require more configuration and operation fees than the hybrid networks. Therefore, how a private network is configured depends on the network characteristics (e.g., security level, network latency for service, operating cost, etc.) required by the customer.

Compared to 4G, a big challenge of 5G is how to support a broad range of devices and services that come from various verticals. Such services include private network, smart factory, and smart building for enterprises. Therefore, the 5G network should be designed in such a way to provide not only existing macro services but also private services. 

The private network requires several features different from public network, such as easy installation, easy management, etc. To this end, Samsung has developed a private network solution called Compact Core. This paper outlines the private network using Samsung Compact Core, as well as the appropriate deployment plans and benefits.
