Page 5 ETS 300 179: 1992 Fore wo rd This European Telecommunication Standard (ETS) has been produced by the Network Aspects (NA) Technical Committee of the European Telecommunications Standards Institute (ETSI). In acco
13、rdance with CCIlT Recommendation 1.130 ll, the following three level structure is used to describe the supplementary telecommunications services as provided by European public telecommunications operators under the pan-European Integrated Services Digital Network (ISDN): - Stage 1 : is an overall se
14、rvice description, from the users standpoint; - Stage 2: identifies the functional capabilities and information flows needed to support the service described in stage 1 ; and - Stage 3: defines the signalling system protocols and switching functions needed to implement the service described in stage
15、 1. This ETS details the stage 1 aspects (overall service description) for the Advice Of Charge: charging information during the call (AOC-D) supplementary service. Stage 2 and stage 3 aspects are detailed in ETS 300 181 (1 992) and ETS 300 182 (1 9921, respectively. 3404583 0048850 399 Page 7 ETS 3
16、00 179:1992 1 Scope This standard defines the stage one of the Advice Of Charge: charging information during the call (AOC-0) supplementary service for the pan-European Integrated Services Digital Network (ISDN) as provided by European public telecommunications operators. Stage one is an overall ser
17、vice description from the users point of view (see CCITT Recommendation 1.130 ll), but does not deal with the details of the human interface itself. This standard defines the interworking requirements of private ISDNs with the public ISDN. In addition this standard specifies the base functionality w
18、here the service is provided to the user via a private ISDN. This standard does not specify the additional requirements where the service is provided to the user via a telecommunications network that is not an ISDN but does include interworking requirements of other networks with the public ISDN. Ch
19、arging principles are outside the scope of this standard. Interaction with supplementary services not listed in Clause 8 are outside the scope of this standard. The AOC-D supplementary service enables a user to receive information on the recorded charges for a call during the active phase of the cal
20、l. The AOC-D supplementary service is applicable to all circuit-switched telecommunications services. This standard is applicable to the stage two and stage three standards for the ISDN AOC-D supplementary service. The terms “stage two“ and “stage three“ are also defined in CCITT Recommendation 1.13
21、0 ill. Where the text indicates the status of a requirement (.e. as strict command or prohibition, as authorisation leaving freedom, or as a capability or possibility), this shall be reflected in the text of the relevant stage two and stage three standards. Furthermore, conformance to this standard
22、is met by conforming to the stage three standard with the field of application appropriate to the equipment being implemented. Therefore, no method of testing is provided for this standard. 2 Normative references This standard incorporates, by dated or undated reference, provisions from other public
23、ations. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to, or revisions of, any of these publications apply to this standard only when incorporated in it by amendment or revision. For u
24、ndated references the latest edition of the publication referred to applies. 121 i31 CCITT Recommendation I. 130 (1 988): “Method for the characterisation of the telecommunication services supported by an ISDN and network capabilities of an ISDN“.

28、s Digital Network 5 Description The AOC-D supplementary service shall apply to the basic access and to the primary rate access. The AOC-D supplementary service provides the served user with cumulative charging information during the call. The information can be sent for all calls, or on a per call b
29、asis. The charge information given shall relate to the charges incurred on the network to which the served user is attached. The structure, contents and application of charging information is given in Annex A. 6 Procedures 6.1 Provision and withdrawal The AOC-D supplementary service shall either be
30、provided on a subscription basis or be generally available. The AOC-D supplementary service can be offered with one subscription option. Only one value can be selected. Advice Of Charge: charging information during the call Subscription option Table 1 Values Invocation I - For all calls automaticall
31、y I - On a per call basis (NOTE) NOTE: If the AOC-D supplementary service is generally available, then the value “on a per-call basis“ should be the default value. Withdrawal shall be at the request of the subscriber or for service provider reasons, , 3Y04583 OOY8852 LbL Page 9 ETS 300 179:1992 6.2
32、Normal procedures 6.2.1 Activation, deactivation and registration The AOC-D supplementary service shall be activated on provision and deactivated on withdrawal. The AOC-D supplementary service requires no registration. 6.2.2 Erasure 8 Not applicable. 6.2.3 Invocation and operation Depending on the v
33、alue of the subscription option, the AOC-D supplementary service shall be invoked on all calls, or it can be invoked by the served user on a per call basis. If the AOC-D supplementary service is provided on a per call basis, the user shall request the AOC-D supplementary service when originating a c
34、all in order to invoke the AOC-D supplementary service. The network shall transfer charging information to the served user when an appropriate cost increment occurs. The rate of sending information can be limited such that information shall not be sent more frequently than every t seconds, .e. infor
35、mation shall be sent every t seconds, or when the increment occurs whichever is later. The value of t shall be a network option. If the call is free of charge to the served user, this shall be indicated (either by the value “O”, or by ”free of charge”). If the call becomes free of charge to the serv
36、ed user during the call, the indication can be given at that time. This indication shall not be repeated periodically (for a special case see subclause 8.1 5). When the call is terminated, the overall charge for the call, even if it was free of charge, shall be sent to the served user. The structure
37、, contents and application of the charging information is given in Annex A. 6.2.4 Interrogation Not applicable. 6.3 Exceptional procedures 6.3.1 Activation, deactivation and registration Not applicable. 6.3.2 Erasure Not applicable. 6.3.3 Invocation and Operation If a served user who is not provided
38、 with the AOC-D supplementary service attempts to invoke the AOC-D supplementary service, then the attempt to invoke the AOC-D supplementary service shall be rejected by the network and the user shall be informed of the reason. M 3404583 0048853 OT8 M Page 10 ETS 300 179: 1992 If the charging inform
39、ation related to a call is not available, this shall be indicated to the served user using the recorded charges “not available“ and shall not be repeated periodically (for a special case, see subclause 8.1 5). If for any reason, no charging information is provided at all on a call, then the user sha
40、ll assume that the information is not available. The user cannot assume that the call is free of charge. If at the end of the call, the network recognises that the information of a particular recorded charge is incomplete, then the recorded charge “not available“ shall be included in the type of cha
41、rging information relating to “total charges“. 6.3.4 Interrogation Not applicable. 7 Intercommunication considerations 7.1 Interworking with non-ISDNs There is no impact on the operation of the AOC-D supplementary service. 7.2 Interworking with private ISDNs The AOC-D supplementary service shall be
42、supported across the internetwork interface between ISDNs (.e. public or private). 8 Interaction with other supplementary services 8.1 Advice of charge services 8.1.1 Charging information at call set-up time No impact, .e. neither supplementary service shall affect the operation of the other supplem
43、entary service. 8.1.2 Charging information during the call Not applicable. 8.1.3 Charging information at the end of the call If both the AOC-D supplementary service and the advice of charge: charging information at the end of the call supplementary service are invoked, then when the call is terminat
44、ed, only the information related to the advice of charge: charging information at the end of the call supplementary service shall be given. 8.2 Call waiting No impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.3 Call hold No impact, .e. neithe
45、r supplementary service shall affect the operation of the other supplementary service. NOTE: In the case that a served users outgoing call is being held and the AOC-D supplementary service is invoked, the charging information is sent when appropriate whilst the call is on hold. = 3404583 004BB54 T34
46、 Page 11 ETS 300 179: 1992 8.4 Explicit call transfer When a user transfers a call, the charge up to that time shall be sent as a subtotal charge. The AOC-D supplementary service shall then be considered as completed. 8.5 Number identification services 8.5.1 Calling line identification presentation
47、No impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.5.2 Calling line identification restriction No impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.5.3 Connected line identification pr
48、esentation No impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.5.4 Connected line identification restriction No impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.6 Closed user group No
49、impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.7 Completion of calls to busy subscriber No impact, .e. neither supplementary service shall affect the operation of the other supplementary service. 8.8 Conference services 8.8.1 Conference call, add-on 8.8.1.1 Conference controller NOTE 1 : Some networks may not support the AOC-D supplementary service in conjunction with the conference call, add-on supplementary service, or may only give part of the information, e.g. due to off-line processing of the charg
