Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission)
form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC
participate in the development of International Standards through technical committees established by the
respective organization to deal with particular fields of technical activity. ISO and IEC technical committees
collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in
liaison with ISO and IEC, also take part in the work.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3.
In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the national bodies casting a vote.
International Standard ISO/IEC 15430 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information
technology,SubcommitteeSC6, Telecommunications and information exchange between systems.

Introduction
This International Standard is one of a series of International Standards defining services and signalling protocols
applicable to Private Integrated 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 International Standard specifies the Wireless terminal call handling additional network features.

features
1 Scope
This International Standard specifies the Wireless terminal call handling additional network features (ANF-WTMI,
ANF-WTMO), which are applicable to various basic services supported by Private Integrated Services Networks
(PISN). Basic services are specified in ISO/IEC 11574.
Additional network feature Wireless terminal incoming call (ANF-WTMI) directs incoming calls to a WTMI user
within a PISN regardless of the WTMI user's geographical location within the PISN, provided the WTMI user's
location is known.
Additional network feature Wireless terminal outgoing call (ANF-WTMO) detects an outgoing call from a WTMO
user and establishes it as a basic call, regardless of the user's geographical location within the PISN. It also
provides the WTMO user's service profile for use by outgoing call control, or alternatively passes the call to the
WTMO user's home location for processing.
Service specifications are produced in three stages, according to the method described in CCITT Recommendation
I.130. This International Standard contains the stage 1 and stage 2 specifications of ANF-WTMI and ANF-WTMO.
The stage 1 specification (clauses 6 and 7) specifies the service as seen by users of PISNs. The stage 2
specification (clauses 8 and 9) identifies the functional entities involved in the service and the information flows
between them.
2 Conformance
In order to conform to this International Standard, a stage 3 International Standard shall specify signalling protocols
and equipment behaviour that are capable of being used in a PISN which supports the services specified in this
International Standard. This means that, to claim conformance, a stage 3 International Standard is required to be
adequate for the support of those aspects of clauses 6 and 7 (stage 1) and clauses 8 and 9 (stage 2) which are
relevant to the interface or equipment to which the stage 3 International Standard applies.
3 Normative references
The following normative documents contain provisions which, through reference in this text, constitute provisions of
this International Standard. For dated references, subsequent amendments to, or revisions of, any of these
publications do not apply. However, parties to agreements based on this International Standard are encouraged to
investigate the possibility of applying the most recent editions of the normative documents indicated below. For
undated references, the latest edition of the normative document referred to applies. Members of ISO and IEC
maintain registers of currently valid International Standards.
