10、4 Ob55703 58T W FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of the ITU. The ITU-T is responsible for studying technical, operating and t
11、ariff questions and issuing Recommendations 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 their turn, prod
12、uce Recommendations on these topics. The approval of Recommendations by the Members of the ITU-T is covered by the procedure laid down in WTSC Resolution No. 1. In some areas of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis wit
13、h IS0 and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency. INTELLECTUAL PROPERTY RIGHTS The ITU draws attention to the possibility that the practice or implementation of th
14、is Recommendation may involve the use of a claimed Intellectual Property Right. The 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
15、 date of approval of this Recommendation, the ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to

22、Network “Capability Set 1 “ (IN CS-1) compliant stage 2 description of Universal Personal Telecommunication (UPT). It does not in any way provide an implementation or technology-dependent description. It identifies the functional capabilities and information flows needed to support the service for U
23、PT Service Set 1 on IN CS-1, the initial phase of UPT introduction, as defined in Recommendations F.850 i and F.851 2. Recommendation F.851 2 categorizes the functionality into essential and optional. Not all the features of Recommendation F.85 1 2 can be supported by existing networks. This Recomme
24、ndation 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. All UPT procedures described in this Recommendation are associate
25、d with a call, as required by IN CS-1 capabilities, and are invoked by interruption of call processing. Only the relationships related to IN service execution are addressed in this Recommendation. This Recommendation does not address the relationship between UPT service and basic call. This relation
26、ship is as prescribed for IN CS-1 services and is described in Recornmendation Q. 1214 3. It should be noted that the definitions of CCAF and CCF are based on corresponding Q.71 6 ISDN definitions but are modified for use in IN. In particular, the enhanced basic call state model of the IN defines st
27、andard Detection Points (DPs) at which IN service feature logic instances can be invoked. These DPs correspond to the Q.71 “hooks“ where an ISDN supplementary service interfaces to the 4.71 basic call model. Call modelling and the SSF/CCF functional entity are described in detail in clauses 3/Q.1214
28、 and 4/Q.1214 3. In CS-1, the SSFKCF functional entity is treated as indivisible, i.e. the interface between CCF and SSF is not a matter for CS-1 standardization. The procedures, functional entities and information flows described in this Recommendation relate to service provision across multiple ne
29、tworks, to the level of Intelligent Network CS-1 capabilities, by allowing access to the UPT users home service providers database 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 no UPT
30、 service profile transfer is provided from the UPT users home database to the originating network database. All interactions with SDFh are controlled by the SCF in the originating network, in conformance with CS-1 guidelines. NOTE - The format of this Recommendation is not totally consistent with th
31、e 4.65 9 Unified Functional Methodology. The reason for this is that the corresponding stage 3 Q.1551 SI was completed and published prior to this stage 2 activity. SDLs can be found in Recommendation Q.i.55 1 SI. FEAS were not considered as a critical problem. The relationship between this Recommen
32、dation and UPT Service Set 1 as defined in Recommendation F.851 2 is as follows: - - Service provided - Telephone (Le. voice-grade connection). Networks involved - All voice networks (e.g. PSTN, ISDN, PLMN). Recommendation Q.1541 (05/98) 1 1.1 o Features Included in this Recommendation (supported by

46、tations. 3.2 Terms not defined in Recommendation F.851 2 The following terminology is used in this Recommendation: 3.2.1 General terms A CS-1 UPT environment consists of one or more bearer networks (PSTN, ISDN, and PLMN) as defined below: 3.2.1.1 UPT network: A bearer network capable of processing U
47、PT calls and procedures. This is a network with IN functionality platform and UPT Service Logic Program (SLP). 3.2.1.2 UPT supporting network: A bearer network capable of recognizing a UPT access code and routing the corresponding UPT call to a UPT network. This network is also able of handling UPT-
48、 specific signalling information in order to process the delivery of the incoming UPT calls up to the destination UPT user. In this network neither UPT Service Logic Program on IN platform nor IN functionalities are required. However, it is capable of providing UPT service-specific information on ca
49、ll completion. 3.2.1.3 non-UPT supporting network: A bearer network that treats a UPT call as a regular voice call. A non-UPT supporting network does not recognize UPT access code or UPT number on call origination, and does not pass UPT service-specific information on call completion. A minimum of one UPT network is required in a UPT environment. 3.2.2 Specific terms 3.2.2.1 home network The network with which the users UPT service provider is associated is described as the “home network“.
