Introduction The present document is part of a TS-family covering the 3rdGeneration Partnership Project; Technical Specification Group Services and System Aspects; Telecommunic
22、ation management; as identified below: TS 32.331 “Notification Log (NL) Integration Reference Point (IRP); Requirements“. TS 32.332 “Notification Log (NL) (NL) Integration Reference Point (IRP); Information Service (IS)“. TS 32.336 “Notification Log (NL) Integration Reference Point (IRP): Solution S
23、ets (SS)“. The present document describes the requirements and information model necessary for Telecommunications Management (TM). The TM principles and TM architecture are specified in 3GPP TS 32.101 1 and 3GPP TS 32.102 2 respectively. A communications system is composed of a multitude of Network
24、Elements (NE) of various types and, typically, different vendors, which inter-operate in a co-ordinated manner in order to satisfy the network users communication requirements. The occurrence of faults in an NE may cause deterioration or loss of this NEs function. Fault Management is the functional
25、area, which allows the operator to detect the occurrence of faults in the network in real-time. Configuration Management and Performance Management are two more functional areas, which require the operator to be alerted to certain conditions in the network. A standard general-purpose mechanism for t
26、he management of Notification Logs containing selected or all notifications from the network is required to provide an ability to perform historical analysis on faults and conditions, which occurred in the network. The TS 32.33x-series constituting the Notification Log IRP, sets forth such a mechani
27、sm - and the present document contains the concept and IRP requirements definition. ETSI ETSI TS 132 331 V14.0.0 (2017-04)53GPP TS 32.331 version 14.0.0 Release 141 Scope The present document specifies overall requirements for Notification Log Management over Itf-N. Clause 4 provides the Notificatio
28、n Log Management concept for the manipulation of Notification Logs and the retrieval of notifications selected for logging. Clause 5 of the present document defines the functional requirements for the Notification Log IRP, for the purpose of Notification Log Management, as seen from a Network Manage
29、r (NM) though Itf-N. The Itf-N is fully standardized so as to connect systems of any vendor to an NM via this interface. 2 References The following documents contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (ide

ETSI ETSI TS 132 331 V14.0.0 (2017-04)63GPP TS 32.331 version 14.0.0 Release 14Notification: defined in 3GPP TS 32.111-1 5. Notification Log: managed
36、 resource in which the notifications are stored Notifications logs contain Notification Log Records. Notification Log may represent a physical or a logical/virtual storage, and which is not apparent to an IRPManager. Notification Log Record: records track information about when a particular notifica
37、tion was entered into the Notification Log and the details of the notification Each Notification Log Record is associated with one notification, where a notification may be an alarm or an event. 3.2 Abbreviations For the purposes of the present document, the following abbreviations apply: COTS Comme
38、rcial Off The Shelf EM Element Manager IRP Integration Reference Point LM Log Management NE Network ElementNM Network Manager OS Operations System4 Notification log Management concept A general-purpose Notification Logging mechanism is required to hold notifications related to different functional a
39、reas in the network. Any Notification Log must, at any one point in time, be capable of holding fault management alarms, configuration management events, performance management events, and event log management events. A log is capable of capturing all semantics carried in a notification. Only those
40、requirements covered by clause 5 and as applicable to the Notification Log IRP IS shall be considered as valid requirements for compliance to the standard defined by the present document. 4.1 Notification Log Management Notification logs are resources in a communications network. An operator needs t
41、o be able to create Notification Logs, delete Notification Logs, query Notification Logs and to delete records. To allow an operator to do this a Notification Log management framework needs to be in place. The following aspects for Notification Log Management are derived from ITU-T Recommendation X.
42、735 8: a) The definition of a flexible Notification Log control service, which will allow selection of Notification Log records that are to be logged by a management system (NMs or EMs) in a Notification Log or a particular Notification Log. b) The ability for a client system to modify the criteria
43、used in logging notification records. c) The ability for a client system to determine whether the logging characteristics were modified or whether notifications log records has been lost. d) Specification of a mechanism to enable Notification Logging to be suspended and subsequently to be resumed. e
44、) The ability for a client system to retrieve and delete Notification Log records. f) The ability for a client system to create and delete those Notification Logs. g) The ability to log partial notifications. Another aspect is listed below: ETSI ETSI TS 132 331 V14.0.0 (2017-04)73GPP TS 32.331 versi
45、on 14.0.0 Release 14- Ability to export a log to an industry standard format such as XML. Such an export facility would allow the analysis and reporting of logs to be carried out by COTS tools. 4.2 Detection of the Notification Log state The Notification Log management system must notify all interes
46、ted OS about its current state. An event-based approach is used to update OSs on the current state of the Notification Log. To facilitate the notification of attribute or state changes, a Notification Log has the capability to generate such events, which all OSs may subscribe to via the Notification
47、 IRP 3GPP TS 32.302 3. The Notification Log management system may also emit Notification Log creation and log deletion notifications to signal the creation or deletion of a particular log. Again all interested OSs may subscribe via 3GPP TS 32.302 3 to receive such notifications. To notify OSs about
48、the loss or imminent loss of Notification Log records, the system is able to emit capacity threshold alarms that alert the subscribed OSs that a capacity threshold has been crossed in a particular Notification Log. This threshold value may indicate that the Notification Log is full and incoming noti
49、fications shall be dealt with in a predetermined manner set by an operator. The system may emit other events to notify an OS of the completion of an I/O intensive operation, such as deletion of Notification Log records, or the exporting of a Notification Log. 4.3 Notification Log / Notification Log Record Retrieval An OS may retrieve Notification Log records either by querying a particular Notification Log with a filter, or by exporting a Notification Log, or a particular section of a Notification LogNotification Log.
