SIST ES 282 007 V1.2.1:2009

• Abstract:

  As part of the transfer of common IMS material to 3GPP, replace contents of this specification by an undated reference to the identical 3GPP technical specification 23.417 release 7. There is no technical change to the specification as a result of this work item, although future essential changes to the 3GPP specification can result in technical modification.

SIST ES 282 007 V1.2.1:2009 is a SIST standard for the Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) IP Multimedia Subsystem (IMS) functional architecture. It specifies the IMS core component of the TISPAN NGN functional architecture and its relationship to other subsystems and components. In this edition, the body of the specification is replaced by an undated reference to the identical 3GPP TS 23.417 Release 7, so the document mainly serves as the controlled entry point to that architecture text.

What does SIST ES 282 007 V1.2.1:2009 specify?

SIST ES 282 007 V1.2.1:2009 covers the IMS functional architecture for TISPAN and points readers to the referenced 3GPP specification for the detailed content. The document is organized as scope, references, definitions and abbreviations, then architecture-oriented clauses and two informative annexes.

Annex	What it covers
Annex A (informative)	IMS Access scenarios
Annex B (informative)	IMS interconnection scenarios

The main body is structured around these topics: overall architecture, overview, functional entities, internal reference points, value added services architecture, external interfaces, interconnection with other networks, interface with the Network Attachment Subsystem (NASS), and interface with the Resource and Admission Control Subsystem (RACS). In practice, that tells a reader where the architecture is meant to connect and which subsystems are in scope.

What are the key requirements of SIST ES 282 007 V1.2.1:2009?

The key practical point in SIST ES 282 007 V1.2.1:2009 is that the technical substance is carried by the referenced ETSI/3GPP specification. For implementation, verification, or purchasing decisions, the reader must use TS 123 417 for the architecture details, definitions, and scenario material.

• Clause 1 Scope states that the standard describes the IMS core component of the TISPAN NGN functional architecture and its relationships to other subsystems and components. In practice, this sets the system boundary for architecture work.
• Clause 2.1 Normative references makes ETSI TS 123 417 the indispensable referenced document. That means the architecture text is not self-contained here.
• Clause 3 Definitions and abbreviations says the terms and abbreviations from TS 123 417 apply. Readers should use the same vocabulary when documenting interfaces or design decisions.
• Clauses 4 to 10 cover the architecture structure: overall architecture, overview, functional entities, internal reference points, value added services architecture, external interfaces, and interconnection with other networks. These are the sections an architect uses to map functions and interfaces.
• Clauses 11 and 12 cover the interface with NASS and the interface with RACS. In practice, these are the integration points to check when planning access and admission-control interactions.
• Annex A and Annex B point to IMS access scenarios and IMS interconnection scenarios. They give the scenario context that helps engineers choose the right deployment and interconnect model.
• The scope note says the contents are transferred to 3GPP and that there is no technical change in this work item. For change control, the important point is that later essential changes in the 3GPP specification can alter the technical content.

What terms does SIST ES 282 007 V1.2.1:2009 define?

• IP Multimedia Subsystem (IMS) - The core subsystem covered by this standard, used for the functional architecture described in the document.
• Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) - The ETSI working area that produced this architecture standard.
• Network Attachment Subsystem (NASS) - The subsystem named in clause 11 as one of the architecture interfaces.
• Resource and Admission Control Subsystem (RACS) - The subsystem named in clause 12 as the other major interface point.
• 3GPP - The standards body whose TS 23.417 Release 7 is the referenced technical basis for this document.
• ETSI - The organization behind the original ES 282 007 text and the publisher of the referenced ETSI version.

Who uses SIST ES 282 007 V1.2.1:2009?

SIST ES 282 007 V1.2.1:2009 is used by telecom architects, core network engineers, system integrators, and interoperability or conformance testers working on TISPAN IMS designs. Quality managers and buyers can also use it to check which architecture reference governs a platform or integration project. It matters wherever a team needs to align IMS functions, external interfaces, NASS, RACS, and interconnection scenarios with the referenced standard.

What changed in SIST ES 282 007 V1.2.1:2009 from the previous edition?

The scope states that the common IMS material was transferred to 3GPP and that the contents of this specification were replaced by an undated reference to the identical 3GPP TS 23.417 Release 7. The scope also states that there is no technical change from that work item, while future essential changes to the 3GPP specification can lead to technical modification.

Which standards are used with SIST ES 282 007 V1.2.1:2009?

• ETSI TS 123 417 - This is the normative reference named in clause 2.1. It supplies the terms and definitions, abbreviations, and the technical architecture content that this standard points to, including the material behind clauses 4 to 12 and annexes A and B.

What does the SIST ES 282 007 V1.2.1:2009 document contain?

SIST ES 282 007 V1.2.1:2009 contains front matter, a references clause, definitions and abbreviations, and a sequence of architecture-focused clauses from overall architecture through NASS and RACS interfaces. It also contains two informative annexes for IMS access scenarios and IMS interconnection scenarios. The practical effect is that the document acts as a structured map to the detailed IMS architecture in TS 123 417 rather than repeating that content in full.
