Background technology
In field of network management, Element management system (Element Management System, EMS) mainly finish ITU TMN (International Telecommunications UnionTelecommunication Manager Network, international telecommunication union telecommunication's managerial grid) (the Element Management Layer of the NE management layer in, EML) function, promptly finish device oriented Operation and Maintenance function, distinct device supplier's EMS can't be general usually.Network management system (NetworkManagement System, NMS) mainly finish NML (NetworkManagement Layer among the ITU TMN, NML) function, the operational administrative function of network-oriented is provided, all network element devices in the managed network (being called subnet) are managed.For the situation that has a plurality of equipment supplier's equipment in the managed network, can reach the purpose of the whole subnet of management by the EMS management system.Interface between network management system (nms) and the Element management system (EMS) is called northbound interface (Itf-N, i.e. Interface-N).
When mobile communication equipment breaks down, will produce corresponding warning information, so that the operational administrative personnel understand the generation of fault and locate as soon as possible and fix a breakdown.If NMS has ordered relevant alarm, promptly NMS is provided with some warning information that needs to understand relevant device, and then when relevant device generation dependent failure, EMS is reported to NMS with the warning information of relevant device by northbound interface.According to present processing mode, a fault may cause the generation of a lot of alarms, thereby makes that the quantity of the warning information that transmits by northbound interface is very big, and northbound interface has been caused very big burden.
In order to reduce the burden of northbound interface, at present, industry has proposed mode that warning information is handled in relevant EMS northbound interface (Itf-N) standard, being called advanced alarm filters, one of them research contents just provides the method for the advanced alarm filtration of configurable rule, to reduce alarm, improve the efficient of northbound interface by northbound interface.At present proposed some and can reduce the alarm filtering rule and the method for alarm quantity, as Transient (of short duration alarm), Threshold (threshold value alarm), Toggle senior alarm filtering rule and methods such as (oscillating alarms).Be divided into crucial alarm and non-key alarm by the alarm that equipment is reported according to different rules, filter non-key alarm, only report crucial alarm.
Specifically, the handling process of above-described advanced alarm filter method is as follows:
NMS sends to EMS by northbound interface and carries out the order that advanced alarm filters, and carries the type of the advanced alarm filtering rule that needs execution in the described order;
After EMS receives described order, carry out and the corresponding advanced alarm filtering rule of described type, the alarm that reports according to described advanced alarm filtering rule judgment device is crucial alarm or non-key alarm, if crucial alarm then is reported to NMS by northbound interface with the described crucial information of alarming; If non-key alarm, then do not report the information of this alarm.
But the method for these filtering alarms, just filtered out non-key alarm simply, though reduced alarm quantity by northbound interface, but also caused losing of warning information simultaneously, because after having passed through the advanced alarm filtration, generally having alarm (non-key alarm) has been filtered, and the operational administrative personnel of NMS side can't to distinguish alarm that NMS receives be general alarm or passed through alarm after advanced alarm filters, and can not further investigate analysis to the alarm of having passed through after advanced alarm filters, so just caused losing of information.
Like this, because existing advanced alarm filter method simple filtering fallen non-key alarm, and the operational administrative personnel can not distinguish the type of described alarm, and then can't know comprehensive situation of fault, sometimes even can cause misleading to the operational administrative personnel.

Step 202:EMS is receiving described order, when carrying out the advanced alarm filtering function, according to the alarm that reports with the corresponding advanced alarm filtering rule of described type judgment device is crucial alarm or non-key alarm, if finding an alarm is crucial alarm, then in the information of key alarm, increase the advanced alarm filter relevant information, and the information of the alarm of the key after will changing is reported to NMS;
Described advanced alarm filter relevant information must comprise the type of the advanced alarm filtering rule of execution, the advanced alarm filtering rule is meant Transient, Threshold, Toggle etc., report by type, make NMS can know the advanced alarm filtering rule that EMS carries out according to described type with performed advanced alarm filtering rule.
The advanced alarm filter relevant information that increases is placed in AdditionalInformation (additional information) attribute of warning information.If existing out of Memory in the AdditionalInformation attribute then is increased in last.The message form that increases is: " ...; The AAMInfo=character string; ", wherein " AAMInfo=" expression advanced alarm filter relevant information such as when wherein character string is " Toggle ", represents that the type of the advanced alarm filtering rule of execution is an oscillating alarm.
Step 203:NMS is when receiving new warning information, in warning information, check in the AdditionalInformation attribute whether comprise the advanced alarm filter relevant information, if in warning information, comprise the advanced alarm filter relevant information, then when this warning information of prompting, such as relevant warning information being pointed out by modes such as screen display or acousto-optics, also point out processing, as show that this alarm is the type etc. of the advanced alarm filtering rule of alarm, execution through the advanced alarm filtration treatment the advanced alarm filter relevant information.And, make operating personnel can know the advanced alarm filtering rule of carrying out in the EMS side, and then can understand judgement to the warning information that is filtered by pointing out the type of the advanced alarm filtering rule of carrying out.
Second application example:
The method that reduces alarm information loss during the present invention's second application example advanced alarm filters may further comprise the steps:
Step 301:NMS sends to EMS by northbound interface and carries out the order that advanced alarm filters, and carries the type and the relevant parameters of the advanced alarm filtering rule that needs execution in the described order;
Step 302: in warning information, increase a field AAMInfo (advanced alarm filter relevant information field), EMS is receiving described order, when carrying out the advanced alarm filtering function, if finding an alarm is crucial alarm, give the correct time on needing, then increase the advanced alarm filter relevant information in the AAMInfo field in warning information, the advanced alarm filter relevant information of increase comprises the type of the advanced alarm filtering rule of execution;
If an alarm that reports is not filtered through advanced alarm, then the AAMInfo field is empty;
Step 303:NMS is when receiving new warning information, whether comprise the advanced alarm filter relevant information in the AAMInfo field of inspection in warning information, if in warning information, comprise the advanced alarm filter relevant information, then when this warning information of prompting, when relevant warning information being pointed out by modes such as screen display or acousto-optics, also the advanced alarm filter relevant information is pointed out, as shown that this alarm is the type etc. of the advanced alarm filtering function of alarm, execution through the advanced alarm filtration treatment.
As seen, this example only is to report the mode of advanced alarm filter relevant information different with the difference of first application example.
The 3rd application example:
