8、rnational Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications. 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 Recommend
9、ations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Conference (WTSC), 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 ap
10、proval of ITU-T Recommendations is covered by the procedure laid down in WTSC Resolution 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with IS0 and IEC. NOTE In this Recommendation, the expression “Administr
11、ation“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

23、Set 1 on IN CS-2 - Procedures for universal personal telecommunication: Functional modelling and information flows 1 Scope This Recommendation defines an Intelligent Network “Capability Set 2 (IN CS-2) compliant stage 2 description of Universal Personal Telecommunication (UPT). It does not in any wa
24、y provide an implementation or technology dependent description. It identifies the functional capabilities and information flows needed to support the service for UPT Service Set 1 on IN CS-2, as defined in ITU-T F.850 i and F.851 2. ITU-T F.851 2 categorizes the functionality into essential and opt
25、ional. This Recommendation includes only those service features achievable with current ITU-T signalling Recommendations. Networks not supporting existing ITU-T signalling Recommendations may be unable to provide all the features in this Recommendation that cover the case of UPT capable networks (ab
26、le to process UPT calls and procedures). Only the relationships related to IN service execution are addressed in this Recommendation. The procedures, functional entities and information flows described in this Recommendation relate to service provision across multiple networks, to the level of Intel
27、ligent Network CS-2 capabilities, by allowing access to the UPT users home service providers networwdatabase from the originating network across a network boundary. It is assumed throughout this Recommendation that the UPT user is a visitor on the originating network and it is possible that the UPT
28、service profile transfer is provided from the UPT users home database to the originating network database. All interactions are in conformance with CS-2 guidelines. For backward compatibility, the CS- 1 compliant descriptions proposed in ITU-T Q. 154 1 7 remain applicable in IN CS-2. The relationshi
29、p between this Recommendation and UPT Service Set 1 as defined in ITU-T F.851 2 is as follows: - Service provided - Telephone (i.e. voice-grade connection). - Networks involved - All voice networks (e.g. PSTN, ISDN, PLMN, including IMT-2000). - Numbering - UPT numbering is based on a personal UPT nu

40、and definitions apply: 3.1 Network limitations Terminal address UPT (Universal Personal Telecommunication) UPT access code (UPTAC) UPT number (UPTN) UPT service profile UPT service profile management UPT service provider UPT subscriber UPT user Terms defined in ITU-T F.851 2 3.2 This Recommendation
41、defines the following terms: Terms not defined in ITU-T F.851 2 3.2.1 General terms 3.2.1.1 UPT Capable Network: a bearer network capable of processing UPT calls and procedures. This is a network equipped with the IN Functional Platform, the UPT Service Logic, and the UPT users data. The network may
42、 or may not house the UPT users home network. 3.2.1.2 UPT Assisting Network: a bearer network capable of recognizing a UPT Access Code or a UPT Number (based on the E. 168 Numbering Plan 9) and requesting assistance of a UPT Capable Network (in CS-2 with the SCF-SCF interface). This is a network equ
43、ipped with the IN Functional Platform but not the complete the UPT Service Logic. NOTE - In CS-3 and further, some additional assistance could be used. 3.2.1.3 UPT Supporting Network: a bearer network capable of recognizing a UPT Access Code or a UPT Number (based on the E.168 Numbering Plan 9) and
44、routing the corresponding UPT call to a UPT or UPT-Assisting Network with which there is interworking and business agreement. This network is not equipped with the IN Functional Platform. However, it is capable of providing UPT specific information on call completion. 3.2.1.4 Non-UPT Supporting Netw
45、ork: a bearer network that treats a UPT call as a regular voice call. This network treats the UPT Access Code or the UPT Number on call origination not as a UPT specific codehumber, but rather as an E. 164 number. ITU-T 0.1542 (06/2000) 3 3.2.1.5 UPT Environment: a CS-2 UPT Environment consists of o
46、ne or more bearer networks, PSTN, ISDN, and PLMN, as defined above. A minimum of one UPT Capable Network is required to be present in a UPT Environment. A UPT user can have access to his subscribed UPT service while roaming within a UPT Environment that includes the UPT users home network. 3.2.2 Spe
47、cific terms 3.2.2.1 Home network: the network with which the users UPT service provider is associated is described as the “home network“. The home network contains the database with the service profiles of the associated users. 3.2.2.2 Originating network: the “first“ network that is a UPT Network i
48、n the UPT call processing. If the network from which a UPT service requedcall is originated is only UPT Supporting Network (see above), the originating network will be the UPT Network to which this UPT Supporting Network will routehedirect this UPT requedcall. 3.2.2.3 Terminating network: the called
49、 partys current network is the “terminating“ network. 3.2.2.4 Future and previous visited networks: the future visited network is the remote network where a UPT user will be registered when having processed remote registration. The previous visited network is the network where a UPT user will no longer be registered after remote registration. 3.2.2.5 Home SDF: the “home SDF“ is the UPT service providers SDF in the home network, where the UPT users service profile is stored. It is designated SDFh. 3.2.2.6 Originating SDF: the “originating S
