SIST ES 282 007 V2.1.1:2009

• 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 23.517 release 8. 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

Overview

SIST ES 282 007 V2.1.1:2009 defines the functional architecture for the IP Multimedia Subsystem (IMS) within Next Generation Networks (NGN) as outlined by the TISPAN committee. The standard unifies telecommunications and internet protocol (IP) services to enable advanced multimedia communications across networks. Developed by the Slovenski inštitut za standardizacijo (SIST), this document aligns identically with ETSI ES 282 007 and is harmonized through reference to the 3GPP TS 23.517 Release 8 specification.

Focusing on interoperability and efficient integration of voice, video, and data services, the IMS architecture fosters convergence in digital communications. Although this SIST standard replaces detailed technical content with a reference to 3GPP, it continues to serve as a foundational document for all IMS deployments within converged multimedia environments.

Key Topics

• IP Multimedia Subsystem (IMS):
  Provides a standardized approach for integrating multimedia services, supporting both fixed and mobile next generation networks.

• Functional Architecture:
  Outlines the relationships between IMS core components, subsystems, and their interfaces within the TISPAN Next Generation Network framework.

• Interoperability:
  Ensures seamless interconnection and operation across heterogeneous networks, supporting advanced services such as voice over IP (VoIP), instant messaging, video conferencing, and presence information.

• Reference to 3GPP Specification:
  As part of international convergence in standardization, SIST ES 282 007 V2.1.1:2009 points directly to the undated 3GPP TS 23.517 Release 8 specification, ensuring alignment with global industry practices.

• Future-Proofing:
  While this version introduces no technical changes, it enables the adoption of any essential modifications from the 3GPP specification, supporting ongoing technical evolution.

Applications

The IMS functional architecture defined in this standard is critical for:

• Service Providers:
  Enables the deployment and management of converged voice, video, and data services across both public and private networks with consistent quality and security.

• Network Operators:
  Facilitates the migration from legacy systems to all-IP networks, supporting the integration of diverse services including IP telephony, multimedia messaging, and real-time communications.

• Equipment Manufacturers:
  Provides a consistent framework for designing interoperable network elements and end-user devices supporting IMS features.

• Enterprises:
  Supports advanced unified communications, enabling collaboration, mobility, and multi-device service delivery within organizational networks.

• National and Regional Standards Adoption:
  Establishes a harmonized basis for legal and regulatory frameworks within Slovenia and more broadly across European or global deployment scenarios.

Related Standards

For comprehensive understanding and deployment, consider these related standards and technical specifications:

• 3GPP TS 23.517:
  The primary reference for IMS functional architecture, outlining technical details, definitions, and core relationships within IP-based multimedia networks.

• ETSI ES 282 007:
  The base European standard harmonized by SIST for Slovenian application.

• ISDN (Integrated Services Digital Network) Standards:
  Provide foundational technologies for digital communications integrated with IMS.

• Other TISPAN NGN Documents:
  These cover additional elements and subsystems related to Next Generation Networks, including access, resource and admission control, and security.

By adhering to SIST ES 282 007 V2.1.1:2009, organizations ensure compliance with internationally recognized IMS architecture principles, empowering the next wave of converged telecommunications and internet services.
