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
ISO/IEC 15429:2003 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 ITU-T Rec. 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. ISO/IEC 15429:2003 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. ISO/IEC 15429:2003 is applicable to PINXs which can interconnect to form a PISN.

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. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of the joint technical committee is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO
and IEC shall not be held responsible for identifying any or all such patent rights.
ISO/IEC 15429 was prepared by ECMA (as ECMA-302) and was adopted, under a special “fast-track procedure”, by
Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of
ISO and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 15429:1999), which has been technically revised.

Introduction
This International Standard is one of a series of Standards defining Wireless Terminal Mobility (WTM) 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 International Standard specifies the signalling protocol for use at the Q reference point in support of the WTM Wireless
Terminal Location Registration supplementary service and the Wireless Terminal Information Exchange additional network
feature. The protocol defined in this International Standard forms part of the PSS1 protocol (informally known as QSIG).
This International Standard is based upon the practical experience of ECMA member companies and the results of their active
and continuous participation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization
bodies. It represents a pragmatic and widely based consensus.

Information exchange additional network feature
1Scope
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 ITU-T Rec. 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.

Joint Technical Committee ISO/IEC JTC 1, Information technology, in parallel with its approval by national bodies of
ISO and IEC.
This second edition cancels and replaces the first edition (ISO/IEC 15429:1999), which has been technically revised.

Introduction
This International Standard is one of a series of Standards defining Wireless Terminal Mobility (WTM) 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 International Standard specifies the signalling protocol for use at the Q reference point in support of the WTM Wireless
Terminal Location Registration supplementary service and the Wireless Terminal Information Exchange additional network
feature. The protocol defined in this International Standard forms part of the PSS1 protocol (informally known as QSIG).
This International Standard is based upon the practical experience of ECMA member companies and the results of their active
and continuous participation in the work of ISO/IEC JTC 1, ITU-T, ETSI and other international and national standardization
bodies. It represents a pragmatic and widely based consensus.

1Scope
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 ITU-T Rec. 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.
