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:

• TS 32.381: Partial Suspension of Itf-N Integration Reference Point (IRP); Requirements.
• TS 32.382: Partial Suspension of Itf-N Integration Reference Point (IRP); Information Service (IS).
• TS 32.386: Partial Suspension of Itf-N 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 realise the functional capabilities over this interface. The basic structure of the IRPs is defined in TS 32.101 and TS 32.102. Information of an event is carried in a notification. An IRPAgent (typically an EM or a NE) emits notifications (see TS 32.302. The IRPManager (typically a Network Management System) receives notifications. In certain scenarios floods of unwanted notifications including alarms would be sent to the IRP manager by network object instances. Thereby the interface and the management systems bear unnecessary load. Even worse: the Operator's awareness is drawn away from really urgent events.

The purpose of Partial Suspension of Itf-N IRP is to define an interface through which an IRPManager can suspend the forwarding of notifications via Itf-N which were generated in parts of the managed systems. The present document contains the Requirements of Partial Suspension of Itf-N IRP. It defines, for the purpose of generally suspending the forwarding of notifications, the basic requirements to be fulfilled on Itf-N.
