ISO IEC 15428:1999 pdf download – lnformation technology — Telecommunications and informationexchange between systems-Privatelntegrated Services Network— Specification, functional model andinformation flows -Wireless TerminalLocation Registration supplementary service and Wireless Terminal lnformation Exchange additional network feature.
ISO IEC 15428 specifies the Wireless Terminal Location Registration supplementary service (SS-WTLR) and the Wireless Terminal Information Exchange additional netsork feature (ANF-WTINFO). which are applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISOIIEC 11574.
The Wireless Terminal Location Registration Supplementary Service (SS-WTLR) enables a WTM user to register at. or dc-register 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, Dc-registration is used to inform the PISN that the WTM user is temporarily unable to make use of the provided services (including the receipt of incoming calls).
The Information Exchange Additional Network Feature (ANF-WTINFO) allows to exchange information about a WTLR user between the Home Data Base and the Visitor Data Base.
Supplementary service and additional network feature specifications arc produced in three stages, according to the method described in CCITT Recommendation [130. This International Standard contains the stage I and stage 2 specifications of SS-WTLR and ANF-WTINFO. The stage I specification (clause 6 and 7) specifies the service/feature as seen by users of PISNs. The stage 2 specification (clause 8 and 9) identifies the functional entities involved in the service/feature 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 supplementary service or additional network feature 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 clause 6 and 7 (stage 1) and clause 0 and 9 (stage 2) which are relevant to the interface or equipment to which the stage 3 International Standard applies.

4.2Other definitions
Additional Network Feature (ANF): A capability, over and above that of a basic service, provided by a PIlSN, but notdirectly to a PISN user.
Directory PINX: A PINX which provides a mapping function to a WTM user’s PISN number or permanent identity fromanother type of identity indicating the same WTM user.
Fixed part (FP): A physical grouping of some or all of the fixed component parts of a mobile radio system.These wouldinclude one or more radio equipments attached to an antenna system. It could also include common control functions andinterfaces to the PINX.
Home Data Base (HDB):The data base in which the current location and all associated parameters of a wireless terminal arestored.
Home PINX: The PINX which has direct access to the HDB entry for a particular WTM user.
Location Area (LA): The coverage area in which a wireless terminal may receive and make calls as a result of a singlelocation registration.
Network Assigned ldentity (NAI): A temporary identity assigned by the PISN to a WTM user. This identity comprises:
a PISN number sufficient to identify the PINX assigning the NAI; and
-a local identity valid while the user is registered.
PISN authority: The body or its representative responsible for arranging the service with the service provider.PISN user: The user of the network layer services provided by a PISN.
Service profile: The specific collection of PISN services and service options which a PISN user can utilizc.Visitor Area (VA): The area covered by a single VDB.
Visitor Data Base (VDB):The data base in which all relevant parameters concerning a wireless terminal are stored for as longas the terminal is located in an area controlled by that data base.
Visitor PINX: The PINX which is serving a WTM user in a visitor area.
Wireless Terminal Mobility (WTM): The ability of a wireless terminal to be in continuous motion whilst accessing and usingthe telecommunication services offered by the PISN, as well as the capability of the network to keep track of the location of thewireless terminal within the coverage area of the radio system used.
WTLR user: The user of Supplementary Service “Wireless Terminal Location Registration”(SS-WTLR).wTM information: The information for a WTM user managed by a VDB.
