Brief History This Standard is one of a series of ECMA Standards defining services and signalling protocols applicable to Private Integrated Services Networks (PISNs). The seri
4、es uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This particular Standard specifies the Advice of Charge supplementary services. This Standard is based upon the practical experience of ECMA me
5、mber companies and the results of their active and continuous participation in the work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus. Compared to the 1st Edition of Standard ECMA-211 (published by ECMA
6、in December 1994), the 2nd Edition (published by ECMA in June 1997) incorporated changes in order to achieve complete alignment with International Standard ISO/IEC 15049:1997(E) published by ISO/IEC in May 1997. Adopted as 3rd Edition of Standard ECMA-211 by the General Assembly of December 2001. -

26、tion given by AOC-E 69 Annex D - Charging assumptions for advice of charge in PISNs 71 1 Scope This Standard specifies the Supplementary Services Advice of Charge (SS-AOC), which are applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are spe
27、cified in ECMA-142. SS-AOC is a set of supplementary services which enable a user to receive information about the charging of its calls that leave the PISN and enter another network. AOC-S enables the user to receive information about the charging rates at call set-up time and also to receive furth
28、er information during the call if there is a change of charging rates. AOC-D enables the user to receive information on the recorded charges during the active phase of the call. AOC-E enables the user to receive information on the recorded charges when the call is terminated. The provision of chargi
29、ng information to the called user, the provision of charging information for calls that do not leave the PISN, and PISN accounting are outside the scope of this Standard. Charging assumptions which apply to the specification of SS-AOC in this Standard are contained in annex D. Service specifications
30、 are produced in three stages, according the method described in ETS 300 387. This Standard contains the stage 1 and stage 2 specifications of SS-AOC. The stage 1 specifications (clauses 6, 7, 8) specify the supplementary services as seen by users of PISNs. The stage 2 specification (clause 9) ident
31、ifies the functional entities involved in the supplementary services and the information flows between them. 2 Conformance In order to conform to this Standard, a Stage 3 standard shall specify signalling protocols and equipment behaviour that are capable of being used in a PISN which supports the s
32、upplementary services specified in this Standard. This means that, to claim conformance, a Stage 3 standard is required to be adequate for the support of those aspects of clauses 6, 7 and 8 (stage 1) and clause 9 (stage 2) which are relevant to the interface or equipment to which the Stage 3 standar
33、d applies. 3 References (normative) The following standards contain provisions which, through reference in this text, constitute provisions of this Standard. All standards are subject to revision, and parties to agreements based on this Standard are encouraged to investigate the possibility of apply
