ISO/IEC 15050: 1997 (E) OISOIIEC
Foreword
IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the
specialized system for worldwide standardization. National bodies that are members of IS0 or IEC participate in the
development of International Standards through technical committees established by the respective organization to deal with
particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part in the work.
In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft
International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the national bodies
casting a vote.
International Standard ISO/IEC 15050 was prepared by ECMA (as ECMA-212) and was adopted, under a special “fast-track
procedure”, by Joint Technical Committee ISOLIEC JTC 1, Information technology, in parallel with its approval by national
bodies of IS0 and IEC.
Annex A forms an integral part of this International Standard. Annexes B, C and D are for information only.

Introduction
This International Standard is one of a series of standards defining services and signalling protocols applicable to Private
Integrated Services Networks. The series uses the ISDN concepts as developed by ITU-T (formerly CCITT) and is also within
the framework of standards for open systems interconnection as defined by ISO.
This International Standard specifies the signalling protocol for use at the Q reference point in support of the Advice Of
Charge supplementary services.
The International 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 JTC 1, ITU-T, ETSI and other international and national standardization
bodies. It represents a pragmatic and widely based consensus.

Advice of charge supplementary services
1 Scope
This International Standard specifies the signalling protocol for the support of the Advice Of Charge supplementary services
(SS-AOC) at the Q reference point between 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 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 during 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 terminated.
The Q reference point is defined in ISOLIEC 11579- 1.
Service specifications are produced in three stages and according to the method specified in CCITT Recommendation 1.130.
This International Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified
by the stage 1 and stage 2 specifications in ISOPIEC 15049.
The signalling protocol for SS-AOC operates on top of the signalling protocol for basic circuit switched call control, as
specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services
specified in ISO/IEC 11582.
This International Standard 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 relevant stage 1 specifications.
This International Standard is applicable to PINXs which can interconnect to form a PISN.
2 Conformance
In order to conform to this International Standard, a PINX shall satisfy the requirements identified in the Protocol
Implementation Conformance Statement (PICS) proforma in annex A.
Conformance to this International 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 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this International
Standard. At the time of publication, the editions indicated were valid. All standards are subject to revision, and parties to
agreements based on this International Standard are encouraged to investigate the possibility of applying the most recent
editions of the standards indicated below. Members of IEC and IS0 maintain registers of currently valid International
Standards.

the PISN and enter another network.
The three AOC supplementary services are:
a) Charging information at call set-up time (AOC-S)
the charging rates at call
SS-AOC-S enables the user to receive information about set-up time and also to receive further
information during the call if there is a change of charging rates.
b) Charging information during 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 terminated.

---------------------- Page: 9 ----------------------
OISO/IEC
ISO/IEC 15050: 1997 (E)
These three supplementary services are supported across the PISN by charge rate provision, interim charge provision and final
charge provision or combinations thereof.
Note - For example, SS-AOC-D could be supported by charge rate provision, by interim charge provision, or by charge rate provision in conjunction with
final charge provision.
