20、alized system for worldwide standardization. National bodies that are members of ISO 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. ISO and IEC technical co
21、mmittees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. Internati
22、onal Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
23、Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or al
24、l such patent rights. ISO/IEC 19460 was prepared by ECMA (as ECMA-300) and was adopted, under a special “fast-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. This second edition cancels and replace
25、s the first edition (ISO/IEC 19460:2001), which has been technically revised. ISO/IEC 19460:2003(E) vi ISO/IEC 2003 All rights reserved Introduction This International Standard is one of a series of Standards defining services and signalling protocols applicable to Private Integrated Services Networ
26、ks (PISNs). The series 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 International Standard specifies the signalling protocol for use at the Q reference point in support of the Call Trans
27、fer supplementary service. The protocol defined in this International Standard forms part of the PSS1 protocol (informally known as QSIG). This International Standard is based upon the practical experience of ECMA member companies and the results of their active and continuous participation in the w
28、ork of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus. ISO/IEC 2003 All rights reserved 1 1S c o p e This International Standard specifies the signalling protocol for the support of the Single Step Call Tra
29、nsfer supplementary service (SS-SSCT) at the Q reference point between Private Integrated Network services eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN). SS-SSCT is a supplementary service which enables a user, user A, to transform an existing call between
30、user A and user B into a new call between user B and a user C whereby user A does not have a call established with user C prior to call transfer. The Q reference point is defined in ISO/IEC 11579-1. Service specifications are produced in three stages and according to the method specified in ETS 300
31、387. 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 ISO/IEC 19459. The signalling protocol for SS-SSCT operates on top of the signalling protocol for basic circuit switche
32、d 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 refe
33、rence point between Single Step Call Transfer and other supplementary services and ANFs. 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
34、 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-SSCT and other supplementary services and ANFs for which signalling protocols at the Q reference po
35、int are supported in accordance with the stage 3 standards concerned. 3 Normative references ISO/IEC 11571:1998, Information technology - Telecommunications and information exchange between systems - Private Integrated Services Networks - Addressing ISO/IEC 11572:2000, Information technology - Telec
