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 ISD

4、N concepts as developed by ITU-T and conforms to the framework of International Standards for Open Systems Interconnection as defined by ISO/IEC. This particular Standard specifies the signalling protocol for use at the Q reference point in support of the Message Waiting Indication supplementary ser

5、vice. The protocol defined in this Standard forms part of the PSS1 protocol (informally known as QSIG). This 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 intern

6、ational and national standardization bodies. It represents a pragmatic and widely based consensus. Compared to the 2nd Edition of Standard ECMA-242 (published by ECMA in September 1997), the 3rd Edition incorporated changes to allow indication of multimedia messages. Compared to the 3rd Edition of S

7、tandard ECMA-242 (published by ECMA in December 1998), this 4th Edition incorporates migration to ASN.1 version 1997 as well as changes in order to achieve complete alignment with International Standard ISO/IEC 15506:2000(E) published by ISO/IEC in March 2000. Adopted as 4th Edition of Standard ECMA

18、8 / X.209 33 1 Scope This Standard specifies the signalling protocol for the support of the Message Waiting Indication supplementary service (SS-MWI) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network

19、 (PISN). The supplementary service MWI enables a Served User to be sent a Message Waiting Indication and also enables this Message Waiting Indication to be cancelled. The Served User may also be permitted to interrogate the Message Centre for any Message Waiting Indication. The Q reference point is

20、defined in ECMA-133. Service specifications are produced in three stages and according to the method specified in ETS 300 387. This 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 ECMA-241. T

21、he signalling protocol for SS-MWI uses certain aspects of the generic procedures for the control of supplementary services specified in ECMA-165. This Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SS-MWI and other

22、 supplementary services and ANFs. NOTE 1 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 Standard is applicable to PINXs which can interconnect to form a PISN. 2 Conformance In order to conform

23、to this Standard, a PINX shall satisfy the requirements identified in the Protocol Implementation Conformance Statement (PICS) proforma in annex A. Conformance to this Standard includes conforming to those clauses that specify protocol interactions between SS-MWI and other supplementary services and

24、 ANFs for which signalling protocols at the Q reference point are supported in accordance with the stage 3 standards concerned. 3 References (normative) The following standards contain provisions which, through reference in this text, constitute provisions of this Standard. All standards are subject

25、 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.
