3、G-SMS) . Brief History This Standard is one of a series of ECMA Standards defining services and signalling protocols applicable to Private Integrated Services Digital Networks (PISNs). The series uses ISDN concepts as developed by ITU-T and conforms to the framework of International Standards on Ope

4、n Systems Interconnection as defined by ISO/ IEC. It has been produced under ETSI work item DTS/ECMA-00228. This particular Standard specifies the signalling protocol for use at the Q reference point in support of the Short Message Service. The protocol defined in this Standard forms part of the PSS

5、1 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 international and national standardization bodies. It represents a pra

6、gmatic and widely based consensus. This ECMA Standard is contributed to ISO/IEC JTC1 under terms of the fast-track procedure, for adoption as an ISO/IEC International Standard. This ECMA Standard has been adopted by the General Assembly of June 2001. . List of corrected errata for ECMA-325 25 Septem

This Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 s

48、pecifications in ECMA-324. The signalling protocol for SMS operates on top of the signalling protocol for the connection oriented call independent APDU transport mechanism and uses certain further aspects of the generic procedures for the control of supplementary services specified in ECMA-165. This

49、 Standard also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between SMS and supplementary services and ANFs. This Standard is applicable to PINXs which can be interconnected to form a PISN. 2 Conformance In order to conform to this Standard, a PINX shall satisfy the requirements i
