17、4846:2003(E) ISO/IEC 2003 All rights reserved v Foreword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the devel
18、opment of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmen
19、tal, 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. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of th
20、e joint technical committee is to prepare International Standards. 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. A
21、ttention 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 all such patent rights. ISO/IEC 14846 was prepared by ECMA (as ECMA-203) and was adopted, under a special “fast-track
22、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 replaces the first edition (ISO/IEC 14846:1996), which has been technically revised. ISO/IEC 14846:2003(E) vi ISO/IEC 2003
23、All rights reserved Introduction This International Standard is one of a series of Standards defining services and signalling protocols applicable to Private Integrated Services Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Stand
24、ards 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 Intrusion supplementary service. The protocol defined in this International Standard forms part of the PSS1 protocol (inf
25、ormally 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 work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization bodies. It represents a prag
26、matic 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 Call Intrusion supplementary service (SS-CI) at the Q reference point between Private Integrated services Network eXchanges (PINXs) con
27、nected together within a Private Integrated Services Network (PISN). SS-CI is a supplementary service which, on request from the calling user, enables the calling user to establish communication with a busy called user by breaking into an established call between the called user and a third user (un
28、wanted user). 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 300 387. This International Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identif
29、ied by the stage 1 and stage 2 specifications in ISO/IEC 14845. The signalling protocol for SS-CI 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 ser
30、vices 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-CI and other supplementary services and ANFs. NOTE 1 - Additional interactions that have no impact on the signa
31、lling 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
