Method for identifying remote RF unit in distributed base station and remove RF unit

Abstract

The invention relates to a method for marking remote radio unit in distributed base station, wherein it uses RRU to enter into maintain state; RRU controls panel instruction lamp to mark the remote ratio unit at maintain state; and the invention also discloses a relative remote radio unit. With said invention, RRU can quickly recognize the maintaining RRU, to improve network quality.

Description

technical field [0001] The invention relates to a distributed base station, in particular to a method for identifying a remote radio frequency unit in a distributed base station and the remote radio frequency unit. Background technique [0002] Distributed base stations are relative to traditional base stations. In a traditional base station, the BBU (BaseBand Unit, baseband unit) and RRU (Remote Radio Unit, remote radio frequency unit) of the base station are concentrated in one cabinet; in a distributed base station, the base station is divided into two independent parts, respectively The BBU and the RRU are deployed, and the BBU and the RRU are connected through optical fibers or other methods. [0003] Please refer to figure 1 , is a schematic diagram of a distributed base station. A distributed base station contains a BBU and multiple RRUs. The BBU and RRUs are installed and deployed in different physical locations. For example, the BBU is installed in a standard com...

Problems solved by technology

[0011] It can be seen from the above prior art that using serial numbers or marks to identify RRUs is not conducive to carrying out on-site maintenance work

When the technical maintenance personnel go to the site to maintain the RRU, they must first record the serial number or number of the RRU to be maintained, and then compare the copied serial number or number with the serial number or number marked on the RRU to confirm the RRU to be maintained. It is not only cumbersome to do, but also may make mistakes when recording, which is not convenient for on-site maintenance personnel to find RRUs in maintenance status

If the RRU configuration is modified remotely, the RRU number changes, but the number mark on the RRU shell cannot be modified in real time, which may cause the actual number of the RRU to be inconsistent with the number on the shell. The RRU number finds the RRU that needs to be maintained, so the second identification method still has the problem that the number data is inconsistent with the actual RRU mark number, and the RRU cannot be found.
