Description
[technical field]
The present invention relates to the Mobile communication direct base station technology, be specifically related to a kind of self-cure monitoring method and device thereof of digital RF far-drawing system.
[technical background]
In the covering of mobile communications network, cover the digital RF far-drawing system of remote device as mobile communication signal, the reliabilty and availability of system there is higher requirement, particularly the monitoring to system realizes having tighter requirement; But because coverage condition and environment is totally different, add the problem of system itself, as because the deviation of the operation of hardware subsystem, and the defective more or less of software subsystem design existence itself, it is unusual to make that software or communication link occur, causing between Base Band Unit in the system, extension unit monitoring host computer module and each the uplink downlink functional module can't interaction data, can't communication transmitting data between Base Band Unit and the extension unit, digital RF far-drawing system is misoperation alarming information report mobile communications network Surveillance center.If can't in time solve, then cause the system can't operate as normal even paralysis on the one hand because of some little problems, influence the covering of mobile communications network; Mobile communications network Surveillance center causes the increase of operator's cost because of solution misoperation warning information on the other hand.
[summary of the invention]
For this reason, purpose of the present invention will overcome above-mentioned deficiency exactly, and a kind of self-cure monitoring method of digital RF far-drawing system is provided.
