According to some embodiments of the invention, the intermediate node is wired to the 5G edge cloud, e.g., the intermediate node and the 5G edge cloud may be wired through a ubiquitous cable network. The 5G edge cloud and the 5G core network are connected by wire, for example, the 5G edge cloud and the 5G core network can be connected by wire through a ubiquitous cable television network.

For example, 5GoC terminals may be located in different rooms (e.g., bedrooms, living room, study room, etc.), and 5GoC terminals in different rooms may be connected to the 5GoC office via coaxial cables. Thus, the indoor 5G signal can be deeply covered.

As shown in fig. 1, the 5G network system based on the wired network includes: 5G core network, 5GoC edge cloud, 5GoC local side and 5GoC terminal.

The 5GoC terminal is disposed in the user room, and can be installed in any room by the operator or the user. The network element is formed by combining a femto module and a coaxial cable channel module, and completes the functions of 5G terminal access, channel establishment with upstream equipment and the like. The network element can be a set top box, a home gateway, an integrated antenna and the like in equipment form, can provide output interfaces such as an Ethernet interface and a coaxial cable, can also provide Wi-Fi service at the same time, and can adopt installation modes such as a desktop, a wall hanging mode and a ceiling sucking mode.
