ETSIEN 301 098 V1.1.1 (1998-08)51ScopeFor some management applications, activities and/or operations have to be scheduled. This scheduling can be dependentof various factors (e.g. time of day, type of day) and it can be repeated (e.g. daily, weekly, bi-weekly). Schedulingactivities can also require more information than a simple on/off scheduling, if e.g. the scheduling can select one out ofthree or more alternatives.To manage this type of scheduling a generic solution needs to be applied. This solution shall be useful for a number ofdifferent management applications.The scope of the present document is to model the support functions for this generic solution at the NE/OS interface.Requirements for temporary override and automatic/manual fall-back to a previous management schema are outside thescope of the present document.2ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, subsequent revisions do apply.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]ITU-T Recommendation M.3100 (1995): "Generic network information model".[2]ITU-T Recommendation X.208 (1993): "Specification of Abstract Syntax Notation One (ASN.1)".[3]ITU-T Recommendation X.721 (1992): "Information technology - Open Systems Interconnection -Structure of management information: definition of management information".[4]ITU-T Recommendation X.746 (1995): " Information technology - Open Systems Interconnection -Systems management: scheduling function".[5]ITU-T Recommendation X.720 (1992): "Information technology - Open Systems Interconnection -Structure of management information: management information model".3AbbreviationsFor the purposes of the present document, the following abbreviations apply:ASN.1Abstract Syntax Notation OneNENetwork ElementOCObject ClassOSOperations SystemSMOScheduled Managed ObjectSOScheduler ObjectSIST EN 301 098 V1.1.1:2003



ETSIEN 301 098 V1.1.1 (1998-08)64Scheduling function4.1Functional requirementsSome management applications (e.g. charging or routing) need time/type of day dependent scheduling function. Tomanage these dependencies, the functional requirements are the following:R.1Scheduling information that is communicated to the scheduled object shall be independent of the action the scheduled object performs. The scheduler has no knowledge about this action.R.2Several independent schedulers can co-exist.R.3A scheduler can schedule several objects.R.4One SMO can be scheduled by several SO.R.5Scheduler shall be able to handle trigger points.R.6Scheduler shall be able to handle intervals.R.7Scheduler shall be able to schedule activities that have more than two states.R.8Scheduling shall be possible on base of type of day (e.g. weekend, Christmas, bank holiday).R.9At least daily and weekly periodicity shall be possible for the periodicity of trigger points and intervals.R.10It shall be possible to limit the duration of periodical repetitions.R.11Overlapping intervals shall be allowed. Precedence rules are therefore needed in order to decide which interval is active.R.12It shall be possible to retrieve from the scheduler all the objects it is scheduling.Besides these requirements, it is assumed that the relations between the scheduler, the scheduling information and thecorresponding actions to be performed are existing in the scheduled object.4.2References analysisThe scheduling function described in ITU-T Recommendation X.746 [4] provides a function that can schedule a numberof activities within multiple managed objects by a single scheduler and is able to specify the time duration that theschedule is active.This scheduler covers only a part of the functional requirement given in the subclause 4.1 and it is designed for startingand stopping of activities.It could be possible to use it by straining the modelling to the maximum extent. It is not used for the following reasons:· it is not possible to define, for every point in time, different activities for each SMO;· the scheduler schedules activities between two states;· the type of day dependency is not covered;· overlapping intervals are not supported.5ConformanceIn order to claim conformance to this specification, a system needs to support the management functions for all managedobject classes defined in clauses 7 and 8 of the present document. Therefore the clauses 7 and 8 form the mandatory partof the present document.SIST EN 301 098 V1.1.1:2003



ETSIEN 301 098 V1.1.1 (1998-08)76Information model6.1Introduction to the object modelThe scheduling function is realised by two entities, the multiScheduler and the typeOfDayController.The OC multiScheduler extends the functionality of the interval scheduling and aperiodic scheduling as described inITU-T Recommendation X.746 [4]. For information, refer to model description in clause 7 of that document.For interval scheduling, the ITU-T scheduler allows the transition of one activity in a SMO between the active andinactive state. The multiScheduler allows the transition of an activity between several (two or more) states. Each suchstate is associated with an index value. The OC multiScheduler also allows overlapping intervals.For aperiodic scheduling, the OC multiScheduler allows the triggering of (possibly different) activities depending on anindex value. Aperiodic scheduling in the OC multiScheduler can also be used for operation scheduling, as described inITU-T Recommendation X.746 [4].For both types of scheduling, the possibility exists to schedule activities depending on the type of day, e.g. holidays,weekdays.The OC typeOfDayController is used to group days into categories according to their type, e.g. 1st January can beclassified as specialDay1.6.2Functional model0,1Npoints totypeOfDayControllermultiSchedulerpoints toSMON0, 110, MFigure 1: Scheduled selection E-R diagramITU-T Rec.

For OC's descriptions the following table style is used.Table 1: Generic OC's descriptionObject Class: "Object class name"AttributesM/CValue SetOperationActionsM/CNotificationsM/CThe column M/C indicates whether the information presented by the attributes/actions/notifications is mandatory(M) orconditional(C).The column "Value Set" indicates whether the attribute is single-valued or set-valued (see ITU-T RecommendationX.720 [5], subclause 5.1.2.2).The column "Operation" indicates the operations that are possible on the attribute.7.1multiSchedulerThe OC multiScheduler is inherited from ITU-T Recommendation X.746 [4] scheduler. It provides the ability to controlactivities for which more information is required then a simple on/off scheduling. This OC multiScheduler allows thedefinition of multiple independent schedules, each of which is associated with an activity. These activities are associatedto index values or are triggered by operations. In the case of index values, the association between a particular indexvalue and an activity is defined within the SMO.SIST EN 301 098 V1.1.1:2003
