Appointment management covers appointment processes for managing the esta
7、blishment of a mutually acceptable appointment time between the service provider (SP) and the service customer (SC). Appointment management is needed for handling visits to shared facilities or customer facilities: for example, to access customer premises, locked engineering or other facilities, or
8、for joint testing between two enterprises. Appointment management can be used in either the service provisioning or the service assurance process. The requirements and analysis are provided using the management interface specification methodology described in Recommendation ITU-T M.3020. History Edi

10、s the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing
11、 Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization 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
12、. 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 necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “A
13、dministration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) an
14、d 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 equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommend
15、ation 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 a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of cla
16、imed 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, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recom
17、mendation.

20、cross the business-to-business (B2B) and customer-to-business (C2B) interfaces. In a NGN service supply chain, the service customer, the service provider, and the network operator/service provider interwork with each other for service provisioning and service assurance. In both the service provision
21、ing and the service assurance processes, it may be necessary to access the customer premises, locked engineering or other facilities, or to carry out joint testing between two enterprises. So, there are some processes for managing the establishment of a mutually acceptable appointment between two pa
22、rties which may be service customer and service provider, or network operator/service provider and service provider. This Recommendation includes the requirements and analysis for all of these processes for the exchange of appointment management information across B2B and C2B interfaces in support o

ITU-T M.3344 (01/2011) 1 Recommendation ITU-T M.3344 Requirements and analysis for NGN appointment management across the business-to-business and customer-to-business interfaces 1 Scope This Recommendation contains the requirements and analysis for the business-to-business (B2B) and cust
24、omer-to-business (C2B) interfaces of appointment management for NGN. It assumes a multi-service provider environment and is aimed at appointment management to support the deployment of NGN and includes both the B2B and C2B interfaces. Appointment management consists of some processes which include s
25、cheduling an appointment, confirming an appointment, updating or modifying an appointment, cancelling an appointment, reporting appointment(s), tracking the history of an appointment and retrieving an appointment. For regulatory oversight, it is assumed that detailed record-keeping will be maintaine
26、d within the service provider (SP) to support the service level agreement (SLA) or regulatory statute. Third-party request/response operations are dependent upon the privacy business rules defined in the SCs/SPs contract and consequently are considered out of scope for this Recommendation. 2 Referen

40、 ITU-T M.3344 (01/2011) 3 6 Concepts and background Appointment management covers appointment processes for managing the establishment of a mutually acceptable appointment time between the SP and SC. Appointment management is needed for handling visits to shared facilities or customer facilities: fo
41、r example, to access customer premises, locked engineering or other facilities, or for joint testing between two enterprises. Appointment management can be used in either the service provisioning or the service assurance process. Appointment management is part of service fulfilment or service assura
42、nce as defined in ITU-T M.3340. There are two types of business context as to B2B/C2B interfaces. One is that the SC role is taken by an end-user entity. Another is that the SC role is taken by another service provider organization in the overall supply chain. In the first business context, the serv
43、ice provider needs to access customer premises. The appointment management interface is used to schedule appointments. In the second business context, it is possible that a service provider provides a service to the end-user with the co-operation of other service providers or transport providers. Th
44、e SP providing telecommunication services to the end-user plays a SC role, while other service providers or transport providers play the SP role. The B2B/C2B interface is used to convey appointment management information between the other service providers or transport providers (acting as SP) and t
45、he service provider (acting as SC). In the overall supply chain, the SC and SP roles may change depending on the circumstances. However, in any particular situation, even when the SP and the SC are in a peer-to-peer relationship, one entity will play the SC role, while the other will play the SP rol
46、e. It is the responsibility of the SP to perform activities in accordance with the performance limits defined by SLAs or by a regulatory mandate. When a regulator defines the time-frame for the SP to perform an activity, the SP may negotiate the time with the SC only within the bounds of the regulat
47、ory-defined performance time. In the case of a national provider of services, the SP and SC roles may be performed by the same organization. In that case, the regulator may define, on behalf of the “public“ the maximum time allowed for the SP to perform the activity. The initial offered time slot by
48、 the SP shall be such that the activity must be performed within the SLA or the maximum time allowed by regulatory mandate. Co-location is a practice where a service provider will lease space in one of its facilities, e.g., a central office, to another service provider. In co-location, the roles of
49、the SC and SP are reversed. The requirements to support the needs of appointment scheduling for co-location can be met by reversing the roles. Figure 1 describes the procedure of the appointment management. This figure provides two columns, the left side shows the activities performed by the SP, and the right side shows the activities performed by the SC. If needed, both the SP and the SC can request an appointment to each other. Before all the time slots for the appointment are provided, the state of appointment is “unscheduled“. Her
