Abstract
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...
