Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project; Technical Specification Group Services and System As
22、pects; Telecommunication management; as identified below: 32.381: Partial Suspension of Itf-N Integration Reference Point (IRP); Requirements. 32.382: Partial Suspension of Itf-N Integration Reference Point (IRP); Information Service (IS). 32.386: Partial Suspension of Itf-N Integration Reference Po
23、int (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 3GPP TS 32.101 1 and 3GPP TS 32.102 2. Information of an event is
24、carried in a notification. An IRPAgent (typically an EM or a NE) emits notifications (see 3GPP TS 32.302 3. 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 networ
25、k object instances. Thereby the interface and the management systems bear unnecessary load. Even worse: the Operators awareness is drawn away from really urgent events. ETSI ETSI TS 132 381 V15.0.0 (2018-07)53GPP TS 32.381 version 15.0.0 Release 151 Scope The purpose of Partial Suspension of Itf-N I
26、RP 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
27、the forwarding of notifications, 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
28、number, 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

35、ow to specify in a suspension request which managed instances shall be Itf-N suspended. 4.1.2 An IRPManager shall be able to remove a partial suspension of Itf-N. 4.1.3 An IRPManager should be able to request from the IRPAgent a list of the active suspensions. 4.1.4 Impact on logging and alarming: I
36、ts the IRPAgents decision whether or not the suspended notifications are logged, whether or not they go into the alarmList. 4.1.5 Impact on measurements: Measurements are not suspended. 4.1.6 Impact on delta synchronization: Delta synchronization is also not affected by the suspension. 4.2 Requireme
37、nts for notifications 4.2.1 Suspended notifications shall not be sent, need not to be stored for re-sending after the end of the suspension. 4.2.2 Suspension should be applied as soon as possible, but notifications which are already ready to be sent from notification buffers are allowed to be sent.
38、4.3 Security related requirements 4.3.1 Authorization and Authentication of IRPManagers requesting partial suspension of Itf-N may be regarded necessary. 4.4 Multi-Manager Related Requirements 4.4.1 If one IRPManager requests a partial suspension of Itf-N, then a notification shall be sent containin
39、g the information about the suspension. After receiving the notification, IRPManagers should be aware that the IRPAgent can not deliver reliable results for some operations while partial suspension is active. Therefore the IRPManager should not use such operations, e.g. CM and FM or TM, etc. operati
40、ons in the scoped branch of the MIB, which is suspended. 4.4.2 If an IRPManager requests an operation related to suspended instances which are subject of notification forwarding, then a notification may be sent to this IRPManager containing the information about the related suspension. 4.4.3 If one
41、IRPManager removes a partial suspension of Itf-N, then a notification shall be sent containing the information about the suspension revocation. An Itf-N partial suspension may be removed by another IRPManager than the one who requested it. This is useful in order to avoid the critical case that a te
42、mporary Itf-N suspension can not be removed anymore because the initiating IRPManager fails for a longer time. NOTE: The co-ordination between several IRPManagers / NMS operators involved in this functionality is an organizational matter and out of scope of the present document. ETSI ETSI TS 132 381
