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 15429 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information
technology, Subcommittee SC 6, Telecommunications and information exchange between systems.
Annex A forms a normative part of this International Standard. Annexes B to D are for information only.

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 is one of a series of signalling protocol standards that together specify Private
Signalling System Number 1 (PSS1) (informally known as QSIG) for use at the Q reference point between Private
Integrated Services Network Exchanges (PINXs). This International Standard supports the Wireless Terminal
Location Registration supplementary service and the Wireless Terminal Information exchange additional network
feature.

INTERNATIONAL STANDARD  © ISO/IEC ISO/IEC 15429:1999(E)
Information technology — Telecommunications and information
exchange between systems — Private Integrated Services
Network — Inter-exchange signalling protocol — Wireless Terminal
Location Registration supplementary service and Wireless
Terminal Information exchange additional network feature
1 Scope
This International Standard specifies the signalling protocol for the support of the Wireless Terminal Location
Registration supplementary service (SS-WTLR) and the Wireless Terminal Information exchange additional network
feature (ANF-WTINFO) at the Q reference point between Private Integrated Services Network Exchanges (PINXs)
connected together within a Private Integrated Services Network (PISN).
SS-WTLR is a supplementary service which enables a WTM user to register at, or deregister from, the current
location within the PISN. The ability to register at different locations in the PISN at different times enables the WTM
user to maintain the provided services (including the ability to make and receive calls) at different access points.
Deregistration is used to inform the PISN that the WTM user is temporarily unable to make use of the provided
services (including the receipt of calls).
ANF-WTINFO is an additional network feature which enables transfer of restriction information between Home PINX
and Visitor PINX. ANF-WTINFO also enables the Visitor PINX or Home PINX to initiate a check of the current
location information.
The Q reference point is defined in ISO/IEC 11579-1.
Supplementary Service specifications and Additional Network Feature specifications are produced in three stages
and according to the method specified in CCITT Recommendation I.130. This International 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 ISO/IEC 15428.
The signalling protocol for SS-WTLR and ANF-WTINFO uses certain aspects of the generic procedures for the
control of supplementary services specified in ISO/IEC 11582.
This International Standard also specifies additional signalling protocol requirements for the support of interactions
at the Q reference point between SS-WTLR and other supplementary services and ANFs.
This International Standard is applicable to PINXs which can interconnect to form a PISN.
2 Conformance
In order to conform to this International Standard, a PINX shall satisfy the requirements identified in the Protocol
Implementation Conformance Statement (PICS) proforma in annex A.
