3、01 - URL: http:/www.ecma.ch - Internet: helpdeskecma.ch IW Ecma-212.doc 14-01-02 10,05 . 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 series uses ISDN concepts as developed
4、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 signalling protocol for use at the Q reference point in support of the Advice Of Charge supplementary services. The protocol defined in thi
5、s Standard forms part of the PSS1 protocol (informally known as QSIG). This Standard is based upon the practical experience of ECMA member 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 standardizat
6、ion bodies. It represents a pragmatic and widely based consensus. Compared to the 1st Edition of Standard ECMA-212 (published by ECMA in December 1994), the 2nd Edition incorporated changes in order to achieve complete alignment with International Standard ISO/IEC 15050:1997(E) published by ISO/IEC
7、in May 1997. Compared to the 2nd Edition of Standard ECMA-212 (published by ECMA in June 1997), this 3rd Edition incorporates migration to ASN.1 version 1997 as well as complete alignment to the ISO/IEC International Standard. Adopted as 3rd Edition of Standard ECMA-212 by the General Assembly of De

X.208 / X.209 59 1 Scope This Standard specifies the signalling protocol for the support of the Advice Of Charge supplementary services (SS-AOC) at the Q reference point between
18、 Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN). 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. The three
19、AOC supplementary services are: a) Charging information at call set-up time (AOC-S) SS-AOC-S enables the user to receive information about the charging rates at call set-up time and also to receive further information during the call if there is a change of charging rates. b) Charging information du
20、ring the call (AOC-D) SS-AOC-D enables a user to receive information on the recorded charges for a call during the active phase of the call. c) Charging information at the end of the call (AOC-E) SS-AOC-E enables a user to receive information on the recorded charges for a call when the call is termi
21、nated. The Q reference point is defined in ECMA-133. Service specifications are produced in three stages and according to the method specified in ETS 300 387. This Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage
22、 2 specifications in ECMA-211. The signalling protocol for SS-AOC operates on top of the signalling protocol for basic circuit switched call control, as specified in ECMA-143, and uses certain aspects of the generic procedures for the control of supplementary services specified in ECMA-165. This Sta
23、ndard also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-AOC and other supplementary services and ANFs. NOTE Additional interactions that have no impact on the signalling protocol at the Q reference point can be found in the
24、 relevant stage 1 specifications. This Standard is applicable to PINXs which can interconnect to form a PISN. 2 Conformance In order to conform to this Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation Conformance Statement (PICS) proforma in annex A. Conforma
25、nce to this Standard includes conforming to those clauses that specify protocol interactions between SS-AOC and other supplementary services and ANFs for which signalling protocols at the Q reference point are supported in accordance with the stage 3 standards concerned. 3 References (normative) The
26、 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 applying the most recent editions of the sta
27、ndards indicated below.
