0  IntroductionWord‑p. 5

The present document is part of a TS-family covering the 3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management; as identified below:
32.121:
Advanced Alarm Management (AAM) Integration Reference Point (IRP): Requirements;
32.122:
Advanced Alarm Management (AAM) Integration Reference Point (IRP): Information Service (IS);
32.126:
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 TS 32.150.
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 one received by an IRPManager via the getAlarmList or alarm notifications of Alarm IRP specification, greatly inhibits the operator ability to quickly identify and locate the responsible network faults. AAM IRP is intended to provide methods to improve this situation.

1  ScopeWord‑p. 6

The purpose of Advanced Alarm Management (AAM) IRP is to define an interface through which an IRPManager can categorize alarm notifications.
The present document is the Information Service of AAM. It defines, for the purpose of categorizing alarm notifications, the information observable and controlled by management system's client and it also specifies the semantics of the interactions used to carry this information.
