Abstract
The invention provides a determination method and apparatus for a fault type in a passive optical network (PON). The method comprises: state information, reported by a PON side device, of all ONUs is received, wherein all ONUs are ones under a PON where the PON side device is located and the state information includes a power-down state and a non-power-down state; the ONUs with designated warning information records existing in warning information lists are removed from all ONUs and thus the rest of ONUs are obtained, wherein the designated warning information, wherein the designated warning information is fiber breaking warning information and outage warning information; and according to the state information corresponding to the rest of ONUs, a fault type of the PON is determined. With the method and apparatus, a problem that a type of a PON fault can not be determined when a fault occurs at the PON in the prior art can be solved and thus the efficiency of fault processing by a system is improved.
Description
Technical field
The present invention relates to a point communications field, in particular to failure classes in a kind of passive optical-fiber network PONOther determines method and device.
Background technology
Network service safeguards system provides fault diagnosis, alarming processing, performance early warning, assessment to optimize, add upNumerous utility functions such as analysis, become intelligence, teleprocessing by broadband service guarantee from artificial, in-situ processing,Can serve the links that O&M ensures, lower O&M cost. And fault diagnosis functions are as one of themImportant component part, its accuracy, rapidity directly determine the influence power of whole network service safeguards system.
Along with broadband value-added service is increasing, PON (PassiveOpticalNetwork, passive optical networkNetwork) network rapid deployment, light path is huge. The optical-fiber network of PON is made up of passive device, point optical splitter, lightConnector and optical cable etc. are placed in outdoor for a long time, and the normally long distance of optical cable is laid, and is easy to be subject to the external worldThe impact of environment and breaking down, as connector damages, fibre-optical bending and optical fiber fracture etc. Cable's Fault is madeThe service disconnection accounting becoming is high, and to be wherein that trunk optical fiber is disconnected cause most of Cable's Fault.
In the time that the disconnected fault of trunk optical fiber occurs, under OLTPON mouth, all ONU cannot work, and cause instituteHave ONU (OpticalNetworkUnit, optical network unit) customer service to interrupt, the fault of the type is excellentFirst level is the highest. In troubleshooting, a step of the first step and most critical is exactly by accurate failure judgement type,Then be only the measure of taking. Therefore, as a reliable and stable network service safeguards system, mustSolve the disconnected rapid decision problem of fault of trunk optical fiber, improve the operating efficiency that broadband service ensures.
The method of the disconnected fault of existing judgement trunk optical fiber normally adopts the side of inquiry PON blackout alarmMethod. But there is following limitation in this method: when the optical signal of all ONU under OLTPON mouth all disappearsWhen mistake, system produces the alarm of PON blackout, but ONU has a power failure, branch optical fiber is disconnected and trunkThe disconnected PON optical signal that all can cause of optical fiber disappears. So it is exactly not necessarily main producing the alarm of PON blackoutDry optical fiber is disconnected;
It is line fault or equipment fault that troubleshooting requires judgement. If line fault, as trunk lightFine disconnected, by line upkeep, department is responsible for; If equipment fault, as ONU has a power failure, by plant maintenance departmentBe responsible for, each maintenance department is clear in job responsibility, if network service safeguards system can not accurately judge that PON signal disappearsLose the actual cause of alarm, occur erroneous judgement, ONU power-off fault is distributed to line upkeep department instead of establishStandby maintenance department, will cause fault handling time to extend, and reduce the operating efficiency that broadband service ensures.
For the problem that cannot judge the classification of PON fault in prior art in the time that PON breaks down, at presentEffective solution is not yet proposed.
