8、v 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 tech
9、nical 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 pa
10、rt 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 comm
11、ittee 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,S ub co m mi t t

ISO/IEC ISO/IEC 15430:1999(E) v 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
13、 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.INTERNATIONAL STANDARD ISO/IEC I
14、SO/IEC 15430:1999(E) 1 Information technology Telecommunications and information exchange between systems Private Integrated Services Network Specification, functional model and information flows Wireless terminal call handling additional network features 1 Scope This International Standard specifie
15、s 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 (
16、ANF-WTMI) directs incoming calls to a WTMI user within a PISN regardless of the WTMI users geographical location within the PISN, provided the WTMI users location is known. Additional network feature Wireless terminal outgoing call (ANF-WTMO) detects an outgoing call from a WTMO user and establishes
17、 it as a basic call, regardless of the users geographical location within the PISN. It also provides the WTMO users service profile for use by outgoing call control, or alternatively passes the call to the WTMO users home location for processing. Service specifications are produced in three stages,
18、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
19、 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 PIS
20、N 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 o
21、r 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, a
22、ny 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 docume

As there is no pred
41、etermined access for the connection of a WTMI user to the PISN, the directing of such calls requires that information regarding the location of the WTMI user is available. 6.1.2 Qualifications on applicability to telecommunication services ANF-WTMI is applicable to all basic services defined in ISO/

ANF-WTMI shall be invoked for an incoming call when analysis of the destination number indicates that the called user is a WTMI user. Once invoked, ANF-WTMI shall route
44、the call to the WTMI user using the destination number to determine the address of the PISN access currently in use by the WTMI user.
