10、SO/IEC 20113:2004(E) iv ISO/IEC 2004 All rights reservedForeword 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 t
11、he development 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-g
12、overnmental, 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 ta
13、sk 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. Publication as an International Standard requires approval by at least 75 % of the national bodies casting a
14、 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 all such patent rights. ISO/IEC 20113 was prepared by ECMA (as ECMA-343) and was adopted, under a special “fas
15、t-track procedure”, by Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of ISO and IEC. ISO/IEC 20113:2004(E) ISO/IEC 2004 All rights reserved vIntroduction This International Standard is one of a series defining services and signallin
16、g 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 Standards for Open Systems Interconnection as defined by ISO/IEC. This International Standard specifies the Make Call Request sup
17、plementary service. 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 JTC1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic
18、 and widely based consensus.

19、upplementary service 1 Scope This International Standard specifies supplementary service Make Call Request (SS-MCR), which is related, but not limited, to various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ISO/IEC 11574. The supplementar
20、y service MCR enables a Requesting User to request a Co-operating User to establish a new Requested Call to a Destination User. This new Requested Call between the Co-operating and Destination User can be either a Basic call or call independent signalling connection. Service specifications are produ
21、ced in three stages, according to the method described in ETS 300 387. This International Standard contains the stage 1 and stage 2 specifications of SS-MCR. The stage 1 specification (Clause 6) specifies the supplementary service as seen by users of PISNs. The stage 2 specification (Clause 7) speci
22、fies the functional entities involved in the supplementary service and the information flows between them. 2 Conformance In order to conform to this International Standard, a stage 3 standard shall specify signalling protocols and equipment behaviour that are capable of being used in a PISN which su
23、pports the supplementary service specified in this International Standard. This means that, to claim conformance, a stage 3 standard is required to be adequate for the support of those aspects of Clause 6 (stage 1) and Clause 7 (stage 2) which are relevant to the interface or equipment to which the
24、stage 3 standard applies. 3 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

36、Description 6.1.1 General description The supplementary service MCR enables a Requesting User to request a Co-operating User to establish a new Requested Call to a Destination User. This new Requested Call between the Co-operating User and the Destination User can either be a Basic call or a call in
37、dependent signalling connection. The new Requested Call shall be correlated to the Original Call between the Requesting User and the Co-operating User. 6.1.2 Qualifications on applicability to telecommunication services This supplementary service is applicable to all basic telecommunication services

39、tion Not applicable. 6.2.2.2 Invocation and operation A Requesting User may use SS-MCR to request the set up of a new Requested Call between a Co-operating User and a Destination User. NOTE The Requesting User and the Destination User can be the same user (e.g. Requesting/Destination User is a Messa
40、ge Centre) To invoke SS-MCR the Requesting User may use, if available, an existing signalling connection (either call- related or call-independent) with the Co-operating User, otherwise the Requesting User shall establish a call independent signalling connection to the Co-operating User in order to
41、convey the following information: address information of the Destination User (e.g. Party Number); optionally, number information of the Co-operating User (e.g. Party Number); optionally, number information of the Requesting User (e.g. Party Number); an indication for a Basic Service, if a Basic cal
42、l is requested, otherwise an indication for a call independent signalling connection; a correlation ID for the Original Call and the Requested Call; an indication whether to retain the Original Call after successful establishment of the Requested Call. If the entity serving the Co-operating User sup
43、ports SS-MCR, this entity may check whether the Requesting User is allowed to invoke SS-MCR and if a call independent signalling connection or a Basic call with the indicated Bearer Service can be established. Afterwards, the Co-operating User may be informed about the SS-MCR request. The Requested
44、Call shall be either a Basic call with the requested Basic Service or a call independent signalling connection, due to the received request. Additionally the following information shall be sent to the Destination User: address information of the Requesting User and Co-operating User (i.e. Party Numb
45、er of the Requesting User) if received; a correlation ID for the Original Call and the Requested Call. If the Requested Call is successfully established, an appropriate indication shall be sent to the Requesting User. The Original Call shall be retained or cleared immediately after successful establ
46、ishment of the Requested Call dependent on the corresponding indication received in the initial Make Call Request from the Requesting User. The Co-operating User is responsible for clearing of the Requested Call. In case of retention of the Original Call the Requesting User is responsible for cleari
47、ng of the Original Call to the Co-operating User. 6.2.3 Exceptional procedures 6.2.3.1 Activation, deactivation and interrogation Not applicable. ISO/IEC 20113:2004(E) ISO/IEC 2004 All rights reserved 56.2.3.2 Invocation and operation If the entity serving the Co-operating User does not support SS-M
48、CR or if the validation of the request from the Requesting user fails or a call independent signalling connection or a Basic call with the indicated Basic Service cannot be established, an appropriate error indication shall be sent to the Requesting User. The Requesting User is responsible for clear
49、ing of the Original Call. If the Co-operating User is busy when SS-MCR is invoked, an appropriate error indication shall be sent to the Requesting User. The Requesting User is responsible for clearing the Original Call. 6.3 Interactions with other Supplementary Services / Additional Network Features Interactions with other supplementary services and ANFs for which PISN standards were available at the time of publication of this International Standard a
