2、-T Recommendation (2.736 (Previously “CCIlT Recommendation”) ITU-T RECNNad.73b CLAUSE*L 95 4862591 Ob12123 508 D FOREWORD The ITU-T (Telecommunication Standardization Sector) is a permanent organ of the International Telecommunication Union (). The ITU-T is responsible for studying technical, operat
3、ing and tariff questions and issuing Recommen- dations 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
4、 turn, produce Recommendations on these topics. The approval of Recommendations by the Members of the IT-T is covered by the procedure laid down in WTSC Resolution No. 1 (Helsinki, March 1-12, 1993). ITU-T Recommendation 4.736, clause 1 was prepared by -T Study Group 11 (1993-1996) and was approved
5、under the WTSC Resolution No. 1 procedure on the 17th of October 1995. NOTE In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

17、 the charge card call started. Where the call disposition code indicates the call failed, this shows the date and time of the failure.

24、description The Stage 1 description of ITCC is given in Recommendations E.113, E.116 and E.118. The Stage 2 description of ITCC can be found in clause 7lQ.86. The Stage 3 description of ITCC may premise the use of the Signalling Connection Control Part (SCCP) as defined in Recommendations Q.7 1 1-4.
25、714 and the Transaction Capabilities (TC) as defined in Recommendations Q.771-Q.775 to support validation of a charge card across international boundary. NOTE - Although the use of Blue Book TC will satisfy the needs of the ITCC supplementary service, TC 1992 version may also be applied. The only mo
26、dification needed is a change of the corresponding IMPORT statement in the ASN.1 module for the CC supplementary service. This Recommendation provides a Stage 3 description for the validation of an intemational telecommunication charge card and provision of call information at the end of the call. H
27、andling of the charge card call beyond these two activities such as basic call control or collection of digits is beyond the scope of this Recommendation. Full validation method, which requires checking the charge card number against the card issuer database, making use of real-time communication be
28、tween the card acceptor and the card issuer, is defined by this Stage 3 description. 4 Recommendation Q.736 (10195) ITU-T RECMN*Q-736 CLAUSE+L 95 4862593 Ob32330 748 To validate a charge card, the card acceptor initiates a transaction to the card issuer to invoke “ValidateCard” operation. The origin
29、ator of the validation transaction may be the exchange or the charge card system at the card acceptor. Destination of the transaction may be the service data point at the card issuer. The service data point at the card issuer terminates that transaction by a positive, or negative response (with a ca
30、use as to why the validation should not be granted). The card acceptor could initiate another transaction to supply the card issuer with information to allow a more complete estimate of call activity. This is done in a timely manner after completion of a call or a call attempt, and the message to be
31、 sent to supply this information is denoted as call disposition. The use of call disposition is subject to agreements between card acceptor network operators and card issuer network operators. 1.2.2 Qualification on the applicability to telecommunication services See Recommendation E. 1 16. 1.2.3 St
32、ate definitions The basic call control states of ISUP apply to ITCC. Charge card call Set-up before the validation is not subject of this Recommendation. 1.3 Operational requirements 1.3.1 Provisionailwithdrawal The ITCC service may be provided for a charge card holder based on agreement between the
33、 card acceptor and the card issuer. Withdrawal shall be at a card holders request, or for the card issuer and/or acceptor reasons. 1.3.2 Requirements on the originating network side No specific requirements are identified. The basic call control procedures of ISUP apply to ITCC. Charge card call set
34、- up before the validation is not subject of this Recommendation. 1.3.3 Requirements in the network No specific requirements are identified. In the card acceptor network or card issuer network, TC resources are needed. Charge card call set-up before the validation is not subject of this Recommendati
35、on. 1.3.4 Requirements on the terminating network side No specific requirements are identified. Charge card call set-up before the validation is not subject of this Recommendation. NOTE - This Recommendation premises that the call originating network and the card acceptor network are the same. There
36、 might be, however, a scenario where they could be separate. When this “separate” scenario was taken, a way to maintain ITCC service integrity and to obtain the information from the calling user or the call originating network in order to send validation query, would be outside the scope of this Rec
37、ommendation. 1.4 Coding requirements 1.4.1 Subsystem number The Subsystem Number (SSN) value, as defined in Annex BlQ.713, shall be applied when an SCCP message in relation to the charge card validation for ITCC is routed across the international interface.
