10、rdized interfaces and for services using such connections. Specific charging and accounting principles for point-to-multipoint ATM connections are not currently addressed in this version of this Recommendation. Source IT-T Recommendation D.224 was prepared by ITU-T Study Group 3 (1997-2000) and was

11、approved under the WTSC Resolution No. 1 procedure on 17 December 1999. Recommendation D.224 (12/99) 1 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 perma

12、nent organ of the ITU. The ITU-T 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

13、, establishes the topics for study 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 w

14、ithin ITU-Ts purview, the necessary 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 RIGH

24、R ATM/B-ISDN (Geneva, 1999) 1 Preamble This Recommendation covers charging and accounting principles applicable to B-ISDN/ATM services provided at the ATM layer. 2 Scope This Recommendation sets out the general principles and conditions applicable by Administrations for the capability to transport A

25、TM cells over ATM connections between standardized interfaces and for services using such connections (Recommendations F.811, F.8 13). An ATM connection is characterized through a traffic contract encompassing the Quality of Service (QoS) class as specified in Recommendation 1.356, ATM Transfer Capa

26、bility (ATC) as specified in Recommendations 1.371 and 1.37 1.1, and applicable traffic parameters. Specific charging and accounting principles for point-to-multipoint ATM connections are not currently addressed in this version of this Recommendation. 3 References The following ITU-T Recommendations

31、eU Rate (CCR): The Chargeable Cell Rate of a connection is a single cell rate parameter used to determine the reservation based charge element for that connection. The CCR is a computed simplification of the traffic contract values of the connection to a single cell rate value. The concept of CCR ap

32、plies only to charging and accounting. It is used only in the reservation based charge element. The CCR is computed as a function of the connection parameters, such as QoS class, ATC, source traffic descriptor and associated tolerances. The use and the calculation function for the CCR are Administra

33、tion-specific. 4.1.2 Connection establishment: Connection establishment indicates the moment the connection has been set up and has become available to the user to transport ATM cells. For connections using signalling, this corresponds to the entry into the active state. 4.1.3 Connection release: Co

34、nnection release indicates the moment the connection has become unavailable to the user to transport ATM cells. For connections using signalling this corresponds to the departure from the active state. 4.1.4 Connections active phase: The connections active phase indicates the entire period between c

35、onnection establishment and connection release. 4.1.5 Distance: Distance in the context of this Recommendation is to be related to the facilities made available to realise the connection between the applicable interfaces. It is Administration- specific whether and how distance influences the chargin

36、g parameters. If distance-dependent differentiation is used, an Administration may choose to define distance regions or distance zones to simplify its implementation. 4.2 Abbreviations and acronyms This Recommendation uses the following abbreviations: ABR Available Bit Rate (Rec. 1.371) ABT/DT ATM B

42、rging units, the charge elements and their parameters and the concepts recommended to be used to charge for network utilization. The network utilization charges cover the costs related to the utilization of the network resources. Charge elements and their parameters are introduced below. The use (or

43、 not) of such elements and parameters and their values are administration-specific in case of charging, and subject to agreement between the Administrations involved in case of accounting. Units, elements, parameters and concepts for charging network utilization 5.1 Charging units The following char

44、ging units are applicable to ATM-level charging. e In case duration is used as element in the charge, the unit is second (s). In case a cell rate is used as element in the charge, the unit is cell per second (cell/s). In case usage is used as element in the charge, the unit is cell (cell). e o NOTE

45、- To ease notation, an Administration may choose to use kilocell or megacell as the unit in charging or accounting, instead of a single cell. Such a choice does not affect the essence of the charging or accounting. 5.2 Charge elements For charging individual connections the following elements may be

46、 used: o connection set-up charge element (see 5.2, i); connection set-up attempt (failed) charge element (see 5.2.2); connection modification charge element (see 5.2.3); o Recommendation D.224 (12199) 3 e connection modification attempt (failed) charge element (see 5.2.4); usage based charge elemen

47、t (see 5.2.6). a reservation based charge element (see 5.2.5); e 5.2.1 Connection Set-up charge A connection Set-up charge may be applied to each successfully established connection. This connection Set-up charge may reflect the resources to establish (and to release) the connection, e.g. transport

48、and processing of signalling messages in all relevant nodes along the route, performing route calculations, performing CAC functions in all relevant nodes and the capacity reserved during the connection set-up phase in both directions. Its value is Administration-specific in the case of charging end

49、 customers, and its value is subject to (bilateral) agreements between Administrations in case of accounting. 5.2.2 A connection Set-up attempt charge may be applied in case a connection has not been successfully established. The connection Set-up attempt charge may reflect the resources to attempt the connection Set-up (see 5.2.1). The application of such a connection Set-up attempt charge may depend on the reason for the failure of the attempt. Different policies may be applied according to the cause of the failure. Such policies are Administration-specific in the cas
