SIST-V ETSI/EG 201 720 V1.1.5:2003 is the Slovenian version of ETSI EG 201 720 V1.1.5, an ETSI Guide on the UMTS network functional model for IMT2000 networks based on ITU-T Recommendation Q.1711. It is issued for people who develop UMTS specifications and need to know which parts of Q.1711 apply and which parts ETSI treats as exceptions.

What does SIST-V ETSI/EG 201 720 V1.1.5:2003 specify?

SIST-V ETSI/EG 201 720 V1.1.5:2003 gives guidance for writing UMTS specifications as part of the IMT2000 family. Its main job is to point to material in ITU-T Recommendation Q.1711 that is not applicable in this ETSI context.

The document is organized into a short structure: scope, references, definitions, and a technical clause on exceptions and clarifications to Q.1711. The front matter also includes the IPR notice, foreword, contents, and history.

What are the key requirements of SIST-V ETSI/EG 201 720 V1.1.5:2003?

The guide is not a full network specification. It is a selection aid for spec writers, so the practical task is to use Q.1711 with the ETSI exceptions in mind.

How does the guide frame Q.1711?

• The guide says it supports development of UMTS specifications based on ITU-T Recommendation Q.1711. In practice, this means Q.1711 is the reference model, but not every part is carried over unchanged.
• It identifies material in Q.1711 that is not applicable. In practice, a reader should not assume the whole ITU-T model is valid for every UMTS specification.

Which parts of Q.1711 are treated as exceptions?

Clause 4 identifies the Q.1711 subclauses that are outside the scope of the working group that drafted the guide. The listed topics cover:

• cell selection
• radio resource management
• channel coding
• handover
• paging
• packet services
• compression
• ciphering
• packet data information generation for charging
• radio access control FEs
• terminal aspects

In practice, these are the areas where engineers and specification authors need separate technical judgement instead of automatic reuse of Q.1711 text.

What does the exceptions list mean in practice?

The guide does not rewrite those topics with alternative procedures or rules. Instead, it tells the reader which areas need to be handled elsewhere or reviewed separately. That matters for document authors, because it helps avoid copying requirements into a UMTS specification where they were not intended to apply.

What does the guide say about clarifications?

Clause 4 has a clarifications heading, and the document keeps the focus on exceptions. In practice, readers should treat the guide as a pointer to applicability, not as a detailed interpretation manual.

What terms does SIST-V ETSI/EG 201 720 V1.1.5:2003 define?

• IMT2000: International Mobile Telecommunications system, the family of systems the guide places UMTS within.
• UMTS: Universal Mobile Telecommunications System, the subject of the guide.
• IPRs: essential or potentially essential intellectual property rights notified to ETSI; this matters because implementers may need to review licensing information.
• SPAN: Services and Protocols for Advanced Networks, the ETSI Technical Committee that produced the guide.

Who uses SIST-V ETSI/EG 201 720 V1.1.5:2003?

The guide is used by specification writers, engineers, and standards committees working on UMTS and IMT2000 network architecture. It is also useful for quality managers and reviewers who need to check whether a draft specification follows Q.1711 or intentionally excludes specific parts of it.

What changed in SIST-V ETSI/EG 201 720 V1.1.5:2003 from the previous edition?

The document history lists V1.1.4 from November 1999 and V1.1.5 from February 2000. SIST-V ETSI/EG 201 720 V1.1.5:2003 is identified as identical to EG 201 720 Version 1.1.5.

Which standards are used with SIST-V ETSI/EG 201 720 V1.1.5:2003?

• ITU-T Recommendation Q.1711 - provides the “Network Functional Model for IMT-2000” that this guide uses as its reference point. The guide is built around Q.1711 and marks which parts are not applicable for UMTS specification work.

What does the SIST-V ETSI/EG 201 720 V1.1.5:2003 document contain?

The document contains a short guidance text rather than a large set of technical tables or formulas. Its body is made up of the scope, one reference, a definitions section, and Clause 4 on exceptions and clarifications to Q.1711.

The technical content is mainly a list of Q.1711 subclauses that ETSI treats as exceptions. That makes the document useful for drafting and review work, because it shows where a specification writer should pause and check applicability before reusing material.

The front matter also carries the IPR notice and the copyright notice, and the end of the document records the version history.
