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. It has been produced under ETSI work item DTS/ECMA-00231. This particular Standard specifies the Make Call Request supplementary service. This Standard is based upon the practic
5、al 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 and widely based consensus. This ECMA Standard has been adopted by the G

18、s related, but not limited, to various basic services supported by Private Integrated Services Networks (PISNs). Basic services are specified in ECMA-142. The supplementary service MCR enables a Requesting User to request a Co-operating User to establish a new Requested Call to a Destination User. T
19、his new Requested Call between the Co-operating and Destination User can be either a Basic call or call independent signalling connection. Service specifications are produced in three stages, according to the method described in ETS 300 387. This Standard contains the stage 1 and stage 2 specificati
20、ons 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) specifies the functional entities involved in the supplementary service and the information flows between them. 2 Conformance In order to conform to
21、 this Standard, a stage 3 standard shall specify signalling protocols and equipment behaviour that are capable of being used in a PISN which supports the supplementary service specified in this Standard. This means that, to claim conformance, a stage 3 standard is required to be adequate for the sup
22、port of those aspects of clause 6 (stage 1) and clause 7 (stage 2) which are relevant to the interface or equipment to which the stage 3 standard applies. 3 References (normative) The following standards contain provisions, which, through reference in this text, constitute provisions of this Standar
23、d. 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 standards indicated below.

This new Requested Ca
35、ll between the Co-operating User and the Destination User can either be a Basic call or a call independent 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 telecommun
36、ication services This supplementary service is applicable to all basic telecommunication services. 6.2 Procedures 6.2.1 Provision / withdrawal SS-MCR may be provided or withdrawn after pre-arrangement with the service provider or may be generally available to all users. 6.2.2 Normal procedures 6.2.2
37、.1 Activation, deactivation and interrogation 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.
38、g. Requesting/Destination User is a Message 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 connecti
39、on to the Co-operating User in order to 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 indica
40、tion for a Basic Service, if a Basic call 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. - 4 - I
41、f the entity serving the Co-operating User supports 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 inf
42、ormed about the SS-MCR request. The Requested 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 Requesti
43、ng User and Co-operating User (i.e. Party Number 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
44、or cleared immediately after successful establishment 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
45、 the Requesting User is responsible for clearing of the Original Call to the Co-operating User. 6.2.3 Exceptional procedures 6.2.3.1 Activation, deactivation and interrogation Not applicable. 6.2.3.2 Invocation and operation If the entity serving the Co-operating User does not support SS-MCR or if t
46、he 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 clearing of the
47、 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 Interacti
