ITU-T M.3348 (01/2011) 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 Sect
8、or (ITU-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
9、 four years, 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,
10、 the necessary 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 voluntar
11、y. However, 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 n
12、egative 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 th
13、e use of 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 Recommenda
14、tion, ITU 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

ITU-T M.3348 (01/2011) Introduction The ITU-T M.370x series of Recommendations defines th
17、e management functions applicable in the network management system-element management system (NMS-EMS) interface which includes object management, state management, notification management, performance management and fault management. These common management functions are network independent. While
18、in NGN environment or in a mixed environment of NGN and non-NGN technologies, there are many kinds of service platforms to provide various services. The management and administration interface for controlling the service platform is proprietary to each vendor currently. The service platform consists
19、 of IT resources (including hardware and software aspects), service support applications and services. IETF has created detailed specifications related to the management of IT resources. Moreover, regarding service platforms, the management and administration to services and the service support appl
20、ications are more significant. The specification of the service support applications and services is seldom covered in the current Recommendations so, it is necessary to specify the NMS-EMS management interface for the NGN service platforms. Rec. ITU-T M.3348 (01/2011) 1 Recommendation ITU-T M.3348
21、Requirements of the NMS-EMS management interface for NGN service platforms 1 Scope This Recommendation defines the requirements for managing service platforms used to introduce new service types (e.g., multimedia service) in NGN. The management functions include monitoring and controlling service su
22、pport applications and services supported by service platforms. The purpose of this Recommendation is to provide a standardized interface to manage these services and service support applications. It is out of the scope of this Recommendation to manage the resources based on which the services are p
23、rovided. Management of service instances is out of the scope of this Recommendation. 2 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

The interface is a Q interface, through which an agent (SEMS, which refers to the system providing the SEMF, or service platforms providing embedded SEMF) can communicate management information for its managed entities to a manager (SNM

40、, the service stratum may involve a complex set of geographically distributed service platforms or in the simple case just the service functions in two end-user sites. The service platforms provide the user services, such as a telephone service, a web service, etc. To provide these services, the app
41、lication support functions and service support functions and related control functions in NGN should be covered by the service platform.

45、ario 1 for management of service platforms Rec. ITU-T M.3348 (01/2011) 5 Figure 3 shows the traditional service platform scenario. Each service platform provides a specific service, and its service element management function (SEMF) is provided either by a dedicated SEMS or by itself. The service ne
46、twork management function (SNMF) is provided by a SNMS. This should be supported. Service platform consists of three aspects: Resources, service support applications and service. Resources are common IT infrastructures of the service platform, which consist of hardware and software. Hardware consist
47、s of network devices, storage devices and servers. Software consists of baseware (e.g., operating system, JAVA virtual machine) and middleware (e.g., database, web server, application server). Service support applications are the system procedures to support the services runtime environments, which
48、consist of service creation, service execution, service exposure, service management, security, etc. In Figure 4, the concept of SDP is introduced, so that multiple services can be provided or flexibly created through this. The SEMF is provided either by a dedicated SEMS or by the SDP itself, and th
49、e SNMF is provided by a SNMS.
