10、 of June 1997. STD*ITU-T RECMN Q-1551-ENGL 2797 D 48b259L Ob4LO40 513 9 FOREWORD ITU (International Telecommunication Union) is the United Nations Specialized Agency in the field of telecommunications. The ITU Telecommunication Standardization Sector (IT-T) is a permanent organ of the ITU. The ITU-T
11、 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 Standardization Conference (WTSC), which meets every four years, establishes the topics for stu
12、dy by the ITU-T Study Groups which, in their turn, produce 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 IT-Ts purview, the necessa
13、ry standards are prepared on a collaborative basis with 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
14、 possibility that the practice or implementation of this 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 outsid
15、e of the Recommendation development process. As of the date of approval of this Recommendation, the ITU hadhad 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 t
16、he latest information and are therefore strongly urged to consult the TSB patent database. O ITU 1998 All rights reserved.

Recommendation Q.1551 (06197) V Recommendation Q.1551 APPLICATION OF INTELLIGENT NETWORK APPLICATION PROTOCOLS (INAP) CS-1 FOR UPT SERVICE SET 1 (Geneva, 1997) 1 Scope This Recommendation specifies the application of Core INAP for the UPT se
25、rvice and describes the internetwork interface. It is applicable to UPT Service Set 1 as defined within RecommendationF.851 SI, but is limited to only those features which can be supported by INAP CS-1. This Recommendation includes procedures for handling the call forwarding supplementary services,
26、these enhancements to the procedures are optional. In this Recommendation only the generic SSF-SCF INN operations have been used, this does not preclude the use of the DP Specific operations. For the SSF-SRF case, this Recommendation does not use the assist handoff procedure. The UPT service relies
27、on the IN architecture as described in 4. 2 References and abbreviations 2.1 References The following ITU-T Recommendations and other references contain provisions which, through reference in this text, constitute provisions of this Recommendation.

The interface between SCF and SDF is specified in rN cs-1; SDFh stores all data related to the UPT user (i.e. the database in UPT Phase 1 is centralized); SDFh must as a consequence provide access control functions to chec
41、k whether or not requests received from remote entities are authorized requests or not; SDFh performs the authentication of the UPT user; SDFo stores a list of agreements, which indicates the identity of all the service providers whose subscribers are allowed to access UPT service in SDFos network;
42、SDFo stores a list of service limitations resulting from agreements with service providers or SDFo also stores information related to the management of the UPT service in its network, e.g. charging records which will be used later on for accounting.

44、Recommendation Q.1551 (06/97) 3.2.1 - Requirements on the originating network side Signalling systems used on the UNI will be those for the PSTN and ISDN. For interaction with the user, user-information is to be collected in-band by means of Dual Tone Multi Frequency (DTMF). This means that for ISDN
45、 the D-channel is not used for collecting user- information. In the PSTN, DTMF devices or terminals have to be used, because, for example, the non- fixed length numbers are ended with an #. ISDN terminals have to be provided with DTMF functionality, otherwise it would not be possible to carry in-ban

Data for UPT are contained in the following data model. The aim of that model is
49、 two-fold: first to provide a list of all the data needed to support UPT Service Set 1 from the service and secondly to present the data as formally as possible so that they are ready to be used as parameters of the database operations. Due to the amount of information contained in the data model, the model needs to be formally organized. The information and its associated structure make up the UPT Information Base (UPT-IB). The contents of the data model is described in 5.2.1 and its structure in 5.2.2. The generic information base on which the present UPT-I
