10、TU Telecommunication Standardization Sector (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 Standardi
11、zation Assembly (WTSA), which meets every 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 tec
12、hnology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.

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 obl
14、igatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party.

19、ITU-T has described the provisioning function set group which is contained in configuration management ITU-T M.3400. The provisioning function set group consists of procedures which are necessary to bring equipment into service, not including installation. However, the interface between the network
20、management system (NMS) and the element management system (EMS) of the service provisioning has not been defined. With the rapid growth of next generation networks (NGNs) and the expansion of new NGN services, it is more important for the service provider (SP) to improve the end-user experience. Con
21、sequently, it is necessary to define the NMS-EMS interface for service activation in order to improve the automation capability, effectiveness and quality of service provisioning. This Recommendation contains the requirements for the NGN service activation across the NMS-EMS interface. Rec. ITU-T M.

Desirable requirements are indicated by the use of the word “shou
36、ld“. Optional requirements are indicated by the use of the word “may“ or “can“. Rec. ITU-T M.3347 (05/2012) 3 6 Concepts and background The “service“ used in this Recommendation refers to “service instance“ in all the cases. In the NGN management functional view reference to ITU-T M.3060, the servic
37、e provisioning is supported by several operations systems functions (OSFs) laid in different management layers. The service management function (SMF) is dedicated to service management and manages the service life cycles and service profiles. Each service profile expresses the transport and service
38、resources requirements needed to activate the service and the underlying service resource management function (SRMF) and transport resource management function (TRMF) map these requirements into network parameters of the underlying network elements. The SMF also manages the service and transport res
39、ources required for enabling the activation of services according to the subscription contract, including the required connectivity and its associated characteristics: bandwidth, quality of service (QoS), and level of subscriber line access (SLA). All management functions in SMF are resource/technol
40、ogy independent and will not provide any technical knowledge on the underlying resources involved in the provisioning of services to the customers: no information about transport or service platforms is available through service management functions. The SMF relies on the SRMF and TRMF to map its se
41、rvice-oriented view and information to the required entities in the appropriate NGN resources. The network management function (NMF) interprets the requirements from the SMF into network parameters of the underlying network elements and performs service activation action through the element manageme
42、nt function (EMF) to activate the related resources for a specific service. Figure 1 shows the interface addressed in this Recommendation. The operations system (OS) (managing system) realizes the service activation related function of the NMF and the OS (managed system) realizes the service activat
43、ion related function of the EMF. The interface is a Q interface. Figure 1 The NMS-EMS interface addressed in this Recommendation This Recommendation defines the requirements for the NGN service activation across the NMS-EMS interface in the service provisioning business process. The subscriber is an
44、 entity that can subscribe some services for an SP. The subscribed service must be activated in the SPs network before it can be used; this process has been illustrated in the above paragraphs of this clause. A subscriber is associated with one or more users, who actually use the service. A subscrib
45、er needs to assign services to users, and a service assigned to a user is a user service. As users can have different usage preference for a service, the user service relationship is used to record this requirement. To support the service activation process, the information about the 4 Rec. ITU-T M.
46、3347 (05/2012) subscriber, user, subscribed service and user service need to be configured in the managed system through the interface addressed in this Recommendation. The service in the managed system can be configured by the user after activation for usage preference via the telecommunication net
47、work, and if the managing system wants to receive updated information on the user service relation, it can subscribe to the managed system for notification of updates of the user service relation. 7 Requirements 7.1 Business level requirements 7.1.1 Requirements The general requirements include: Sub
48、scriber configuration User configuration Subscribed service configuration User service relation configuration User service relation update notification Bulk configuration Non-functional requirements 7.1.1.1 Subscriber configuration REQ-SA-FUN-101 The managing system shall be able to request the mana

The information of a specific subscriber includes subscriber ID, subscriber name, subscriber type (organization, individual), etc. REQ-SA-FUN-102 The managing system shall be able to request the managed system to modify the existing subscribers information identified by the subscribers identification.
