4、 CCITT 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 Plenary Assembly of CC1I” which meets every four years, establishes the topics for study and approves Recommendat

5、ions prepared by its Study Groups. The approval of Recommendations by the members of CCIT between Plenary Assemblies is covered by the procedure laid down in CCIT Resolution No. 2 (Melbourne, 1988). Recommendation D.260 was prepared by Study Group III and was approved under the Resolution No. 2 proc

6、edure on the 22 of March 1991. CCITT NOTE! In this Recommendation, the expression “Administration” is used for conciseness to indicate both a telecommunication Administration and a recognized private operating agency.

8、ng principles for services supported by ISDNs are contained in other Recommendations in the D.200-Series. This Recommendation provides a methodology for identifying and displaying charging and accounting capabilities requiring network support. 2 General The tariff and accounting principles contained

9、 in the D.200-Series Recommendations, describe those principles in terms that may not be readily understood by the technical experts who are developing the charging and accounting support mechanisms. This Recommendation provides a methodology for the development and displaying of a more detailed lev

10、el of information that results from expert interpretation of general tariff and accounting principles applied to specific services to be supported by ISDNs. 3 Methodology In order for the technical experts to provide appropriate support mechanisms, there is a need for them to be advised of the struc

11、ture of the charging and accounting requirements. The level of charges is a national matter and is not of concern to the system design technical experts. It may be that the relative size of fields used in the transmission of charging and accounting information will need to be defined in the protocol

12、 development stage (further study). Tariff experts need to examine each specific service and systematically develop and display potential charging and accounting requirements. Emphasis must be placed on the word “potential“ since Administrations may select different combinations of the provided supp

13、ort mechanisms in the implementation of their charging systems. In general, the system design technical experts will need to be advised of the structure of the charging and accounting elements to be supported. 4 Application To ensure that consistency between the tariff and accounting principles and

14、the charging and accounting requirements is maintained, each D.200-Series Recommendation that deals with a specific service should contain an additional section that details the charging and accounting requirements. To ensure consistency of approach in the displaying of that detail, it is recommende

15、d that the approach described in Table A-1D.260 for charging and Table A-2D.260 for accounting be utilized. This approach follows the sequence of identifying the charging or accounting element, identifying its form and unit and further identifying if any of a number of modifying characteristics may

16、be present. Annex B displays a typical application. 5 Application detail 5.1 Recommendation D.210 establishes the basic components for charging and accounting. This Recommendation applies the network mechanisms to those components which are contained in Table A-1D.260 for charging and in Table A-2D.

Recommendation D.260 1 CCITT RECNN*D.260 93 m 4862.593 0560953 6 m 5.2 have been identified so far are defined below: Certain modifiers to the charging and accounting components will also need to be supported. Modifiers that a) Requested service: In principle, charges are raised

18、in relation to the service requested by the customer (e.g. telephony, 64 kbits/s unrestricted, etc.). b) Distance: Utilization charges normally reflect distance sensitivity which tends to be established on the basis of either the crowflight distance between the calling and cailed locations or betwee

19、n the international zones in which they reside. Timelvolume: Utilization charges may also be dependent on the rate period in effect or on the volume transmitted. Chargeablelnon-chargeable units: Certain types of calls or packets may be carried free of charge. Such calls or packets will need to be id

20、entified. Transit: For accounting purposes, it may be required that the use of transit facilities be identified (for further study). c) d) e) 2 ANNEXA (to Recommendation D.260) General structure of network charging and accounting capability elements TABLE A-1D.260 Charging Elements Form Unit Access
