SIST EN 301 824 V1.1.1:2005

SIST EN 301 824 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 824 V1.1.1, a European Standard for Private Integrated Services Network (PISN). It specifies the Wireless Terminal Location Registration supplementary service (SS-WTLR) and the Wireless Terminal Information Exchange additional network feature (ANF-WTINFO). In practice, it tells implementers how wireless terminal location registration, deregistration, and location-information exchange are handled in a PISN.

What does SIST EN 301 824 V1.1.1:2005 specify?

SIST EN 301 824 V1.1.1:2005 specifies service behavior for wireless terminal mobility in a PISN. The scope covers SS-WTLR, which lets a user register at or deregister from the current location, and ANF-WTINFO, which supports exchange of user information between databases.

The document is presented as part of the PISN service and signalling series. The visible text includes the foreword, an endorsement notice for ISO/IEC 15428, clause 3 on normative references, and a document history section. Clause 3 is the place where the ETSI references that apply to this endorsed version are identified.

What are the key requirements of SIST EN 301 824 V1.1.1:2005?

SIST EN 301 824 V1.1.1:2005 focuses on how a wireless terminal user moves within a PISN and how the network tracks that movement. The practical point is service continuity: the network must know where the user is, and whether the user is available for service.

• SS-WTLR registration - The service allows a user to register at the current location in the PISN. For implementers, this means supporting location updates when a terminal moves between access points.
• SS-WTLR deregistration - The service also allows the user to de-register from the current location. In practice, this tells the network that the user is temporarily not available for service handling.
• Service continuity across locations - The scope says that registering at different locations at different times helps the user maintain provided services, including making and receiving calls. For a network designer, this means location state must follow the user as the access point changes.
• Availability signaling - Deregistration informs the PISN that the user is temporarily unable to use the provided services, including receipt of incoming calls. For operations and testing, this affects how incoming traffic is routed or suppressed.
• ANF-WTINFO information exchange - The additional network feature exchanges information about a WTLR user between the Home Data Base and the Visitor Data Base. In practice, roaming or visiting-network records need to be synchronized between those two data stores.
• Endorsement of ISO/IEC 15428 with modifications - The ETSI version applies the elements of ISO/IEC 15428 (1999) with listed changes. That matters because conformance work must follow the ETSI-modified reference set, not the unmodified international text.

What terms does SIST EN 301 824 V1.1.1:2005 define?

• Private Integrated Services Network (PISN) - A private network environment for integrated services and signalling.
• Wireless Terminal Location Registration supplementary service (SS-WTLR) - The service that lets a wireless terminal user register or de-register location within a PISN.
• Wireless Terminal Information Exchange additional network feature (ANF-WTINFO) - The feature that exchanges information about a WTLR user between the Home Data Base and Visitor Data Base.
• Home Data Base - The database associated with the user's home side in the information exchange function.
• Visitor Data Base - The database used when the user is operating in a visited location.
• ISO/IEC 15428 - The international standard that this document endorses with ETSI modifications.

Who uses SIST EN 301 824 V1.1.1:2005?

Telecommunications engineers, PISN equipment vendors, protocol implementers, and test laboratories use this standard when designing or checking mobility-related service behaviour. Quality managers and buyers use it to confirm that a product or network supports location registration and information exchange for wireless terminals in a PISN.

It is most relevant where private networks need service continuity across multiple access points. That includes service specification, signalling implementation, interoperability checking, and procurement review.

What changed in SIST EN 301 824 V1.1.1:2005 from the previous edition?

SIST EN 301 824 V1.1.1:2005 is an ETSI endorsement of ISO/IEC 15428 (1999) with listed modifications. The documented changes replace several references in clause 3 with ETSI documents, and they replace the wording “this International Standard” with “the present document” throughout the text.

Which standards are used with SIST EN 301 824 V1.1.1:2005?

Clause 3 names the normative references used with this document:

• ETSI EN 300 189 - Addressing
• ETSI EN 300 171 - Control aspects of circuit-mode basic services
• ETSI ETS 300 475-1 - Reference configuration for PTN eXchanges (PTNXs)
• ETSI EN 301 828 - Wireless terminal authentication supplementary services
• ETSI ETS 300 387 - Method for the specification of basic and supplementary services
• ISO/IEC 15428 - The international standard endorsed and modified by this European Standard

These references supply the addressing, basic-service control, reference configuration, authentication, and service-specification framework used alongside SS-WTLR and ANF-WTINFO.

What does the SIST EN 301 824 V1.1.1:2005 document contain?

The document contains the ETSI foreword, IPR notice, national transposition dates, endorsement notice, clause 3 with a reference-replacement table, and a short document history. The technical heart of the visible text is the mapping of ISO/IEC references to ETSI equivalents and the wording changes applied to the endorsed standard.

For a reader, that means this is not a product manual or a test report. It is a service-and-information-flow standard that sets the PISN mobility terminology and the reference set used to specify SS-WTLR and ANF-WTINFO.
