Radio remote unit management device, system and method

Abstract

The invention discloses a radio remote unit management device, a radio remote unit management system and a radio remote unit management method. The radio remote unit management device comprises a diagnosis module and an interface, wherein the diagnosis module is used for generating an instruction stream and a data stream according to management information from a user; and the interface is used for transmitting the instruction stream and the data stream to an evolved radio remote unit (eRRU) in a wireless way and receives feedback information from the eRRU in the wireless way. By the device, the system and the method, the debugging efficiency is improved, and the operation and maintenance cost is reduced.

Description

technical field [0001] The present invention relates to the communication field, in particular to a remote radio frequency unit management device, system and method. Background technique [0002] In order to reduce the construction cost of the base station equipment room and the operation and maintenance cost of the operator, the way of distributed base stations is usually adopted, and the evolvable universal radio access network node B (E-UTRAN Node B, referred to as eNodeB) is divided into two parts. A part is a baseband unit (evolved Base Band Unit, referred to as eBBU) and a remote radio unit eRRU (evolved Radio Remote Unit, referred to as eRRU). [0003] The eRRU is generally placed several kilometers or even tens of kilometers away from the eBBU, and the two are connected through optical fibers or cables. Usually, the eBBU performs centralized maintenance on the eRRU remotely, but this maintenance method is conditioned on the normal status of the uplink and downlink l...

Problems solved by technology

[0004] The inventor found that since the eRRU is generally placed on an outdoor elevated shelf, during the maintenance process, the maintenance personnel link the eRRU through the serial port / network port, and the wired connection requires climbing work for line plugging, which often requires climbing work, which causes inconvenience to debugging and diagnosis.
