Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project; T
20、echnical Specification Group Services and System Aspects; Telecommunication management; as identified below: 32.121: “Advanced Alarm Management Integration Reference Point (IRP): Requirements“; 32.122: “Advanced Alarm Management Integration Reference Point (IRP): Information Service (IS)“; 32.126: “
21、Advanced Alarm Management (AAM) Integration Reference Point (IRP); Solution Set (SS) definitions“. The Itf-N interface is built up by a number of IRPs and a related Name Convention, which realize the functional capabilities over this interface. The basic structure of the IRPs is defined in 3GPP TS 3
22、2.150 1. IRPManagers (typically Network Management Systems) and IRPAgents (typically EMs or NEs) synchronize their data concerning alarms or configuration data. In certain scenarios this synchronization is lost or not done. This IRP provides functionality to significantly reduce the amount of data w
23、hich needs to be transferred in order to re-establish synchronization. ETSI ETSI TS 132 121 V14.0.0 (2017-04)53GPP TS 32.121 version 14.0.0 Release 141 Scope The purpose of this set of specifications is to provide a mechanism enabling the IRP Manager to improve the information content of alarms, the
24、reby contributing to reduce the time-to-repair. For this configurable rules for advanced alarm filtering are defined to reduce the number of alarms by applying such advanced alarm filtering. The present document contains the Requirements of Advanced Alarm Management (AAM) on Itf-N IRP. It defines, f
25、or the purpose of AAM on Itf-N, the basic requirements to be fulfilled on Itf-N. 2 References The following documents contain provisions that, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition n
26、umber, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a non-specific reference, the latest version applies. In the case of a reference to a 3GPP document (including a GSM document), a non-specific reference implicitly refers to the latest

29、ments for AAM on Itf-N 4.1 Concept A single network fault may generate a large number of alarms over space and time. In a large and complex network, simultaneous network faults may occur, causing the network operator to be flooded with high volume of alarms. The high volume of alarms, typically the
30、one received by an IRPManager via the getAlarmList or alarm notifications of ETSI ETSI TS 132 121 V14.0.0 (2017-04)63GPP TS 32.121 version 14.0.0 Release 14Alarm IRP specification, greatly inhibits the operator ability to quickly identify and locate the responsible network faults. Therefore it is co
31、nsidered advantageous to have methods categorizing network alarms as insignificant or significant. The word insignificant does not imply “low priority“. In the context of this specification the words significant and insignificant have the following implications: - IRPAgent shall not report alarms ca
32、tegorized as insignificant. - IRPAgent shall report all significant alarms. Reporting only significant alarms and not reporting insignificant alarms would reduce network operators time to locate network faults so that more time can be spent fixing them. When reading the alarmList it can be advantage
33、ous to partition alarms in the alarmList into sets of alarms which might be caused by the same network fault. By assigning network operators to locate network faults based on alarms in such alarm partitions, rather than based on alarm severity, alarm type or reporting location, duplication of networ
34、k operator effort (e.g. two network operators work on two different alarms and their resolutions lead to the same network faults) can be reduced or avoided 4.2 General Requirements for AAM on Itf-N 4.2.1 The IRPManager should be able to request the IRPAgent to a) categorize alarms as insignificant o
35、r significant and b) to act based on these categories, e.g. to discard if insignificant. The IRPManager should be able to cancel such requests. 4.2.2 The standard should define some alarm categorization rules. The standard should also allow vendor to define their own alarm categorization rules. 4.2.
36、3 Possible alarm categorization rule(s) may depend for example on the type of alarm, the environment, the time of day, the type of network element, the alarm severity, the location, position in the containment tree and many more. No restriction is imposed in this regard. 4.2.4 The IRPManager should
37、be able to request the IRPAgent for the list of active categorization rules (i.e. standard defined and vendor defined). 4.2.5 The IRP manager should be able to request the IRPAgent to apply the categorization rule(s) and to remove the insignificant alarms in the following situations: + alarm notific
38、ations to be sent to any IRPManager + advanced alarm management requests by this IRPManager to read the alarm list Certain types of categorization rules are only to be applied to read the alarm list. The term used for these rules is alarm partitioning rules. ETSI ETSI TS 132 121 V14.0.0 (2017-04)73G
