Foreword This Technical Specification (TS) has been produced by ETSI Project Te

17、lecommunications and Internet Protocol Harmonization Over Networks (TIPHON). Introduction The present document uses the Universal Modelling Language (UML) to model the TIPHON Release 4 service capabilities in an object oriented approach. The advantages of such an approach include: the ability to exp

18、ress service capabilities in a semi-formal modelling language; inheritance of the Object Oriented Design paradigm and with it concepts of reuse, inheritance, polymorphism, and extensibility. NOTE: The approach to the definition of service capabilities in TIPHON Release 3 (v1.1.1 of the present docum

19、ent) has been modified in this edition. The approach in v1.1.1 did not specify object-based design methods to develop the service capability model and instead used text to define the service capabilities where those service capabilities were derived from and abstracted from the capabilities and supp

20、lementary services of ISDN. The service capabilities described in the present document exist in the control plane of TIPHON, where this application plane may be vertically apportioned as shown in the figure below: Transport Point to point, Point to multipoint, Multipoint to multipoint Services Telep

32、 Networks UML Unified Modelling Language 4 Services and service capabilities TIPHON standardizes modules of technical functionality that can be implemented using different technologies and terms these as Service Capabilities. A service application is the technical description which, when combined wi

33、th a commercial arrangement, specifies a service. A service capability is a specified set of functionalities that is used to provide a component part of a service application. A single service capability may be used in more than one service application. A service capability is further defined (for t

34、he purposes of the present document) as an operation within one of these root classes or any derived class. 5 Naming TIPHON Release 4 for the support of Public Telephony shall use naming based on the use of numbering plans derived from the application of ITU-T Recommendation E.164 5. EXCEPTION: Numb

35、ering schemes used in private networks. EXCEPTION: Service invocation codes, e.g. emergency number. 6 Overall UML class model Analysis of the suite of services required in TIPHON Release 4 and any current provision of those services in the ISDN or in the Internet (for SIP 6 and ITU-T Recommendation

36、H.323 7), suggest that the following set of UML classes can be used to define TIPHON. Profile: - The profile class specifies the attributes and operations required to support operations on the user profile or service profile (e.g. registration, authentication). Call: - The call class specifies the a

37、ttributes and operations required for the establishment, modification and clearing of a multi-media connection between two users. ETSI ETSI TS 101 878 V4.1.1 (2003-11) 8 Bearer: - The bearer class specifies the attributes and operations required for control of connection based service domain operati

38、ons. Media: - The media class specifies the attributes and operations required to enable communications payload encoding and characterization. Message: - The message class specifies those attributes and operations required for control of message handling including storage, retrieval and maintenance,

39、 in the service domain. In addition the following object types are defined for TIPHON: Transport: - The transport object is manipulated by the media and bearer classes. Two stereotypes are defined in TIPHON: = Service capability; = Notification or return message. It is noted that the stereotypes are

40、 typically invoked and run asynchronously and many operations may be invoked prior to completion of a single operation. The identified classes are shown in figure 1.

45、d in the model, that initializes and terminates transactions such as telephone calls. NOTE: Although there are signals required to be sent to the user these do not form capabilities as defined in other parts of the present document. Therefore other than recognizing the existence of the TIPHON user a

46、s an element in the system that uses service capabilities no specification of the TIPHON user is given. A stereotype may be required to allow notification of the user of the state of operations in the other parts of the service capability model. 6.2 Scope of service capabilities with respect to user

47、 and network The figures that follow show, for a network connection between two users, the scope of each of the classes defined in the present document. call bearer transport ICF ICF ICF media NOTE 1: Call is defined end-to-end. NOTE 2: Bearer is the abstraction of all transport and media encoding s

48、een by the call. NOTE 3: Media objects are carried nominally end-to-end but a single call may have many media objects serially concatenated across transcoding points. NOTE 4: Transport objects exist within a single transport domain between terminal points (either user-terminals or Inter-Connect Func
