5G wireless communication indoor distribution system capable of intelligent backup and implementation method thereof

Abstract

The invention provides a 5G wireless communication indoor distribution system capable of achieving intelligent backup and an implementation method thereof. Through interface expansion on devices in the indoor distribution system, when a device breaks down, automatic switching can be conducted, forwarding is conducted through the other adjacent device connected with the device, and therefore, the automatic switching of communication lines between devices is realized, and the reliability of communication is powerfully guaranteed. The system comprises a DU device used for baseband signal processing and connected with an EU device; the EU device used for expansion connection, and connected with a plurality of RU devices; RU devices used for transmitting and receiving wireless signals. The DU device is at least connected with two lower-level branches, each lower-level branch at least comprises one EU device, the EU device in one lower-level branch is connected to the EU device in the other adjacent lower-level branch, and the RU device connected with the same EU device is connected to form a ring network.

Description

technical field [0001] The invention relates to the technical field of 5G wireless communication, in particular to a 5G wireless communication indoor distribution system capable of intelligent backup and an implementation method thereof. Background technique [0002] With the rapid increase of mobile users and more and more high-rise buildings in cities, the traffic density and coverage requirements are also rising. These buildings are large in size and have a strong shielding effect on mobile phone signals. In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, Cause pilot frequency pollution, the mobile phone frequently switches networks, and even drops calls, which serio...

AI Technical Summary

Problems solved by technology

In the environment of low floors of large buildings, underground shopping malls, underground parking lots, etc., the mobile communication signal is weak, and the mobile phone cannot be used normally, forming a blind area and shadow area of ​​mobile communication; on the middle floor, due to the overlapping of signals from different surrounding base stations, Cause pilot pollution, mobile phone frequently switches networks, or even drops calls, which seriously affects the normal use of mobile phones

In addition, in some buildings, although the mobile phone can communicate normally, the user density is high, the base station channel is crowded, and the mobile phone is difficult to go online.
