Problems solved by technology

The technical problem to be solved by the present invention is that in the prior art, a fault may successively cause multiple alarms to occur, and only a part of the alarms (defined as the main alarm) can best explain the root cause of the fault, while other alarms (defined as the auxiliary alarm) are of great importance to the alarm. It is not very helpful to solve the fault, resulting in the main alarm being overwhelmed by a large number of auxiliary alarms, and the northbound interface is overloaded

Embodiment Construction

[0081] Specific embodiments of the present invention include the following:

[0082] A data structure is defined to represent an alarm correlation rule, that is, to describe which (several) main alarms are related to which (several) auxiliary alarms. In the definition of the alarm correlation rule, at least include the unique identification of the rule (such as rule ID), main alarm characteristics, auxiliary alarm characteristics, system identification of the creator of this rule (such as systemDN), minimum time interval, maximum time interval, alarm recovery delay time etc.

[0083] The alarm feature in this paper refers to a type of alarm generated by an alarm source, and is used to determine whether an alarm matches an alarm correlation rule. Alarm characteristics include alarm type identification and alarm source. The type of the alarm can be identified by the alarm cause (probableCause) defined in the northbound interface. The alarm source refers to the location inform...

Abstract

A method for making filter alarm between network management system and network element management system includes setting alarm correlation rule including master alarm and auxiliary alarm for network element management system by network management system, judging whether alarm message required to be sent by network element management system is master alarm or auxiliary alarm according to alarm correlation rule, sending alarm message to network management system if it is master alarm or otherwise filtering off said alarm message and not sending it to network management system.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for enhancing alarm efficiency between a network management system and a network element management system. Background technique [0002] An interface between an NMS (Network Management System, network management system) and an EMS (Element Management System, network element management system) is called a northbound interface (Itf-N). EMS mainly completes the EML (Element Management Layer, network element management layer) function in the ITU (International Telecommunication Union, International Telecommunication Union) TMN (Telecommunication Management Network, Telecom Management Network), that is, completes the management function of one or more mobile communication devices, Usually the EMS between different equipment suppliers cannot be used universally. The NMS mainly completes the NML (Network Management Layer, network management layer) function in the ITU TMN, ...
