The contents of the present document are subject to continuing work within the TSG and may change following formal TSG approval. Should the TSG
21、 modify the contents of the present document, it will be re-released by the TSG with an identifying change of release date and an increase in version number as follows: Version x.y.z where: x the first digit: 1 presented to TSG for information; 2 presented to TSG for approval; 3 or greater indicates
22、 TSG approved document under change control. y the second digit is incremented for all changes of substance, i.e. technical enhancements, corrections, updates, etc. z the third digit is incremented when editorial only changes have been incorporated in the document. Introduction The present document
23、is part of a TS-family covering the 3rdGeneration Partnership Project; Technical Specification Group Services and System Aspects; Telecommunication management; as identified below: TS 32.331 “Notification Log (NL) Integration Reference Point (IRP); Requirements“. TS 32.332 “Notification Log (NL) (NL
24、) Integration Reference Point (IRP); Information Service (IS)“. TS 32.336 “Notification Log (NL) Integration Reference Point (IRP): Solution Sets (SS)“. The present document describes the requirements and information model necessary for Telecommunications Management (TM). The TM principles and TM ar
25、chitecture 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 Elements (NE) of various types and, typically, different vendors, which inter-operate in a co-ordinated manner in order to satisfy the network users communica
26、tion requirements. The occurrence of faults in an NE may cause deterioration or loss of this NEs function. Fault Management is the functional area, which allows the operator to detect the occurrence of faults in the network in real-time. Configuration Management and Performance Management are two mo
27、re functional areas, which require the operator to be alerted to certain conditions in the network. A standard general-purpose mechanism for the management of Notification Logs containing selected or all notifications from the network is required to provide an ability to perform historical analysis
28、on faults and conditions, which occurred in the network. The TS 32.33x-series constituting the Notification Log IRP, sets forth such a mechanism - and the present document contains the concept and IRP requirements definition.

29、se 151 Scope The present document specifies overall requirements for Notification Log Management over Itf-N. Clause 4 provides the Notification Log Management concept for the manipulation of Notification Logs and the retrieval of notifications selected for logging. Clause 5 of the present document d
30、efines the functional requirements for the Notification Log IRP, for the purpose of Notification Log Management, as seen from a Network Manager (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
31、contain provisions which, through reference in this text, constitute provisions of the present document. - References are either specific (identified by date of publication, edition number, version number, etc.) or non-specific. - For a specific reference, subsequent revisions do not apply. - For a
32、non-specific reference, the latest version applies.

40、on log Management concept A general-purpose Notification Logging mechanism is required to hold notifications related to different functional areas in the network. Any Notification Log must, at any one point in time, be capable of holding fault management alarms, configuration management events, perf
41、ormance management events, and event log management events. A log is capable of capturing all semantics carried in a notification. Only those 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 def
42、ined by the present document. 4.1 Notification Log Management Notification logs are resources in a communications network. An operator needs to 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
43、 Log management framework needs to be in place. The following aspects for Notification Log Management are derived from ITU-T Recommendation X.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 man
44、agement system (NMs or EMs) in a Notification Log or a particular Notification Log. b) The ability for a client system to modify the criteria used in logging notification records. c) The ability for a client system to determine whether the logging characteristics were modified or whether notificatio
45、ns log records has been lost. d) Specification of a mechanism to enable Notification Logging to be suspended and subsequently to be resumed. e) 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
46、Logs. g) The ability to log partial notifications. Another aspect is listed below: - 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. ETSI ETSI TS 132 331 V15.0.0 (2018-07)73GPP
47、 TS 32.331 version 15.0.0 Release 154.2 Detection of the Notification Log state The Notification Log management system must notify all interested 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
48、attribute or state changes, a Notification Log has the capability to generate such events, which all OSs may subscribe to via the Notification 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
49、 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 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 notifications shall be dealt with in a predetermined manner set by an operator. The system may emit other e
