    8、8.0 ITU-T M.3020 2011-07-14 2 ii Rec. ITU-T M.3020 (07/2011) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-

    9、T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WTSA), which meets every four ye

    10、ars, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the nec

    11、essary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. Howev

    12、er, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shall“ or some other obligatory language such as “must“ and the negative

    13、equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of

    14、 a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, IT

    15、U had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database at http:/www.it

    22、Bibliography. 63 Rec. ITU-T M.3020 (07/2011) 1 Recommendation ITU-T M.3020 Management interface specification methodology 1 Scope This Recommendation describes the management interface specification methodology (MISM). It describes the process to derive machine-machine interface specifications based

    23、 on user requirements, analysis and design (RAD). Guidelines are given on RAD using unified modelling language (UML) notation; however, other interface specification techniques are not precluded. The guidelines for using UML are described in this Recommendation. An interface specification addresses

    24、management service(s) defined in ITU-T M.3200 and/or supporting the management processes defined in ITU-T M.3050.x series. Such a specification may support part of or one or more management services. The management services comprise of management functions. These functions may reference those define

    25、d in ITU-T M.3400 or the processes defined in ITU-T M.3050.x series, specialized to suit a specific managed area, or new functions may be identified as appropriate. The methodology is applicable to both the traditional manager/agent style of management interfaces ITU-T M.3010 and the service oriente

    26、d architecture (SOA) principles adopted for the management architecture of next generation networks ITU-T M.3060. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation. At the time

    27、of publication, the editions indicated were valid. All Recommendations and other references are subject to revision; users of this Recommendation are therefore encouraged to investigate the possibility of applying the most recent edition of the Recommendations and other references listed below.

This Recommendation uses the

    34、following terms from OMG UML: activity diagram; actor; association; class; class diagram; classifier; collaboration diagram; composition; modelElement; sequence diagram; state diagram; stereotype; use case. This Recommendation uses the following term from ITU-T M.3060: reference point. 3.2 Terms def

    35、ined in this Recommendation This Recommendation defines the following terms: 3.2.1 agent: Encapsulates a well-defined subset of management functionality. It interacts with managers using a management interface. From the managers perspective, the agent behaviour is only visible via the management int

    36、erface. NOTE Considered equivalent to IRPAgent b-3GPP TS 32.150. 3.2.2 information object class: Describes the information that can be passed/used in management interfaces and is modelled using the stereotype “Class“ in the UML meta-model. For a formal definition of information object class and its

    37、structure of specification, see Annex B. Rec. ITU-T M.3020 (07/2011) 3 3.2.3 information service: Describes the information related to the entities (either network resources or support objects) to be managed and the way that the information may be managed for a certain functional area. Information s

    38、ervices are defined for all IRPs. NOTE Considered identical to the definition of information service found in b-3GPP TS 32.150. 3.2.4 information type: Specification of the type of input parameters of operations. 3.2.5 integration reference point: An architectural concept that is described by a set

    39、of specifications for the definition of a certain aspect of the management interface, comprising a requirements specification, an information service specification, and one or more solution set specifications. NOTE Considered identical to the definition of IRP found in b-3GPP TS 32.150. 3.2.6 manage

    40、ment goals: High-level objectives of a user in performing management activities. 3.2.7 management interface: The realization of management capabilities between a manager and an agent, allowing a single manager to use multiple agents and a single agent to support multiple managers. NOTE Q, C2B/B2B an

    41、d Itf-N (3GPP) are examples of management interfaces. 3.2.8 management role: Defines the activities that are expected of the operational staff or systems that perform telecommunications management. Management roles are defined independent of other components, i.e., telecommunications resources and m

    42、anagement functions. 3.2.9 management scenario: A management scenario is an example of management interactions from a management service. 3.2.10 manager: Models a user of agent(s) and it interacts directly with the agent(s) using management interfaces. Since the manager represents an agent user, it

    43、gives a clear picture of what the agent is supposed to do. From the agent perspective, the manager behaviour is only visible via the management interface. NOTE Considered equivalent to IRPManager b-3GPP TS 32.150. 3.2.11 matching information: Specification of the type of a parameter (possibly refere

    44、nce to IOC or attribute of IOC). 3.2.12 protocol-neutral specification: Defines the management interfaces in support of management capabilities without concern for the protocol and information representation implied or required by, e.g., CORBA and XML. 3.2.13 protocol-specific specification: Defines

    45、 the management interfaces in support of management capabilities for one specific choice of management technology (e.g., CORBA). NOTE Considered equivalent to solution set b-3GPP TS 32.150. 3.2.14 telecommunications resources: Telecommunications resources are physical or logical entities requiring m

    46、anagement, using management services. 4 Abbreviations This Recommendation uses the following abbreviations: 3GPP 3rd Generation Partnership Project ADM Administrative (usage: requirements category) ASN.1 Abstract Syntax Notation One CM Conditional-Mandatory 4 Rec.
