Brief History This Standard is one of a series of ECMA Standards defining Wireless Terminal Mobility (WTM) services and signalling protocols applicable to Private Integr
4、ated 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 particular Standard specifies the signalling protocol for use at the Q reference point in support
5、of the Wireless Terminal Call Handling additional network feature. 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 participat
6、ion 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. Compared to the 1st edition of Standard ECMA-304 (published by ECMA in June 2000), this 2nd Edition incorporates migration to ASN.1 version
7、1997.

X.208 / X.209 49 - iv - . 1 Scope This Standard specifies the signalling protocol for the support of the Wireless terminal call handling additional network features (ANF-WTMI and ANF-WTMO) at the Q referen
27、ce point between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN). ANF-WTMI is a feature that directs incoming calls to a WTMI user within the PISN regardless of the WTMI users geographical location within the PISN, provided
28、that the WTMI users location is known. Roaming outside the PISN is outside the scope of this edition of this Standard. ANF-WTMO permits the PISN to process call requests from a WTMO user at the home location, if required. The Q reference point is defined in ECMA-133. Service specifications are produ
29、ced 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 stage 1 and stage 2 specifications in ECMA-303. The signalling protocol for ANF-WTMI and ANF-WTMO
30、 operates on top of the signalling protocol for basic circuit switched call control, as specified in ECMA-143, and 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
31、for the support of interactions at the Q reference point between ANF-WTMI / ANF-WTMO 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 identi
