Brief History This Standard is one of a series of ECMA Standards defining Wireless Terminal Mobility (WTM) services and signalling protocols applicable to Private Integrated Ser

4、vices 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 particular Standard specifies the signalling protocol for use at the Q reference point in support of the W

5、ireless Terminal Authentication supplementary services. 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

6、work of ISO/IEC JTC1, ITU-T, ETSI and other international and national standardization bodies. It represents a pragmatic and widely based consensus. Compared to the 1st edition of Standard ECMA-306 (published by ECMA in June 2000), this 2nd Edition incorporates migration to ASN.1 version 1997. Adopt

X.208 / X.209 49 1 Scope This Standard specifies the signalling protocol for the support of the Wireless Terminal Authentication supplementary services (SS-WTAT and SS-WTAN) at the Q reference point between Private Integrated services Network eX

29、changes (PINXs) connected together within a Private Integrated Services Network (PISN). Authentication of a WTM user (SS-WTAT) is a supplementary service that enables a PISN, as a security measure, to validate the identity provided by the WTM user. Authentication of the PISN (SS-WTAN) is a supplemen

30、tary service that enables a served WTM user, as a security measure, to validate the identity of the PISN. The mechanisms used in these services are based on the challenge and response method of authentication. Authentication algorithms to be used by these supplementary services are outside the scope

31、 of this Standard. The Q reference point is defined in ECMA-133. Service specifications are produced in three stages and according to the method specified in ITU-T Rec. I.130. This Standard contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the

32、stage 1 and stage 2 specifications in ECMA-305. The signalling protocol for SS-WTAT and SS-WTAN 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

33、interactions at the Q reference point between SS-WTAT / SS-WTAN and other supplementary services and ANFs. This Standard is applicable to PINXs which can interconnect to form a PISN. 2 Conformance In order to conform to this Standard, a PINX shall satisfy the requirements identified in the Protocol
