SIST EN 301 825 V1.1.1:2005

• Abstract:

  SS-WTLR is a supplementary service which enables a WTM user to register at, or de-register from, the current location within the PISN. The ability to register at different locations in the PISN at different times enables the WPM 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 WPM user is temporarily unable to make use of the provided services (including the receipt of incoming 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.

SIST EN 301 825 V1.1.1:2005 is the Slovenian adoption of ETSI EN 301 825 V1.1.1 for Private Integrated Services Network (PISN) signalling. It specifies the inter-exchange signalling protocol at the Q reference point for the Wireless terminal location registration supplementary service (SS-WTLR) and the Wireless terminal information exchange Additional Network Feature (ANF-WTINFO), so implementers can support location registration, deregistration and location-information checks between network exchanges.

What does SIST EN 301 825 V1.1.1:2005 specify?

SIST EN 301 825 V1.1.1:2005 specifies signalling for PISN inter-exchange operation, with the protocol used at the Q reference point. The document is an ETSI European Standard that endorses ISO/IEC 15429 (2003) with ETSI modifications.

The scope focuses on two related functions:

• SS-WTLR, which lets a wireless terminal user register or de-register at the current location within the PISN.
• ANF-WTINFO, which transfers restriction information between Home PINX and Visitor PINX and lets either side check current location information.

In practice, the standard is for systems that need a wireless terminal to keep service access while moving between access points, or to tell the network that the terminal is temporarily unavailable for outgoing or incoming calls.

The document is organized as an endorsement notice over the ISO/IEC text. Clause 3 is updated with ETSI normative references, and a replacement table applies ETSI references throughout the text. The published front matter also gives the foreword, endorsement notice and document history.

What are the key requirements of SIST EN 301 825 V1.1.1:2005?

SIST EN 301 825 V1.1.1:2005 requires readers to apply the ISO/IEC 15429 text with the ETSI changes listed in the endorsement notice. In practical terms, implementers must follow the modified reference set and the replacement wording when using the protocol description.

Protocol function and use

The standard defines the signalling for SS-WTLR and ANF-WTINFO at the Q reference point. This matters because it fixes where the protocol applies in a PISN and which service interactions it supports.

Location registration and de-registration

SS-WTLR allows a wireless terminal user to register at a current location or de-register when the user cannot use the provided services. In practice, network equipment has to handle both states so that calls can be accepted, rejected or forwarded according to the terminal’s current status.

Transfer of restriction information

ANF-WTINFO supports transfer of restriction information between Home PINX and Visitor PINX. This gives the network a way to keep the service picture aligned as the user moves, which is important for enforcing access rules consistently.

Current location checking

ANF-WTINFO also allows the Visitor PINX or Home PINX to initiate a check of current location information. That is useful for keeping registration data current and for deciding whether service control needs to change after the user moves.

Reference framework

The foreword states that the protocol is part of the PSS1 protocol, informally known as QSIG, and that the series uses ISDN concepts and conforms to the OSI framework. For implementers, this places the document within the established PISN signalling family rather than a standalone mobility protocol.

ETSI modifications

Clause 3 adds specific ETSI normative references and the text replaces selected ISO/IEC references with ETSI equivalents throughout the document. This matters because conformity work must use the ETSI-named companion standards, not the original ISO/IEC references.

What terms does SIST EN 301 825 V1.1.1:2005 define?

• PISN (Private Integrated Services Network) - The network environment for which the signalling protocol is specified.
• SS-WTLR (Wireless terminal location registration supplementary service) - The service that lets a wireless terminal user register or de-register location within the PISN.
• ANF-WTINFO (Wireless terminal information exchange Additional Network Feature) - The feature that transfers restriction information and supports location checks between PINX entities.
• Q reference point - The interface where the signalling protocol is used in support of the service and feature.
• PINX - The PISN exchange role used in the document’s Home PINX and Visitor PINX interactions.
• PSS1 - The protocol family that the foreword says includes this document.
• QSIG - The informal name used for the PSS1 protocol family in the foreword.

Who uses SIST EN 301 825 V1.1.1:2005?

SIST EN 301 825 V1.1.1:2005 is used by engineers and system integrators working on PISN signalling, wireless terminal mobility features and inter-exchange call control. It is also relevant to equipment vendors, interoperability testers and network planners who need to implement or verify SS-WTLR and ANF-WTINFO behaviour in PISN exchanges.

In practice, these users work on the protocol at the Q reference point, on Home PINX and Visitor PINX interactions, and on the related ETSI PISN standards that the document references.

What changed in SIST EN 301 825 V1.1.1:2005 from the previous edition?

SIST EN 301 825 V1.1.1:2005 is the ETSI endorsement of ISO/IEC 15429 (2003), modified. The endorsement notice states that the elements of ISO/IEC 15429 apply with ETSI modifications, including added normative references, replacement of references throughout the text, and replacement of the phrase “this International Standard” with “the present document”.

Which standards are used with SIST EN 301 825 V1.1.1:2005?

Clause 3 adds these normative references, each contributing a companion function to the PISN signalling environment:

• ETSI EN 300 189 - addressing
• ETSI EN 300 171 - service description, functional capabilities and information flows for circuit-mode 64 kbit/s bearer services
• ETSI ETS 300 475-1 - reference configuration for PTNXs
• ETSI EN 300 239 - generic functional protocol for support of supplementary services
• ETSI EN 300 257 - call diversion supplementary service
• ETSI EN 301 824 - specification, functional model and information flows for the wireless terminal location registration service and the wireless terminal information exchange feature
• ETSI EN 301 829 - wireless terminal authentication supplementary service
• ETSI EN 301 255 - message waiting indication supplementary service

What does the SIST EN 301 825 V1.1.1:2005 document contain?

The document contains the ETSI endorsement notice, the foreword, the national transposition dates and the clause 3 reference updates. It also includes a table that replaces ISO/IEC references with ETSI references throughout the endorsed text, so readers know which companion standards to use when applying the protocol.

It is mainly a protocol and reference-update document rather than a worked-method or test-procedure standard. For implementation and conformance work, the useful content is the service scope, the protocol placement at the Q reference point, and the linked PISN standards named in clause 3.
