SIST ES 282 007 V1.2.1:2009
Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN) - IP Multimedia Subsystem (IMS) - Functional architecture
General Information
- 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.

ETSI ES 282 007 V1.2.1 (2008-11) - Telecommunications and Internet converged Services and Protocols for Advanced Networking (TISPAN); IP Multimedia Subsystem (IMS); Functional architecture
Overview
SIST ES 282 007 V1.2.1:2009 defines the functional architecture for the IP Multimedia Subsystem (IMS) within the context of TISPAN - the Telecommunications and Internet converged Services and Protocols for Advanced Networking. This Slovenian standard, aligned with the European ETSI ES 282 007, provides a standardized architectural framework for the implementation of IMS in Next Generation Networks (NGN). As a result of harmonization processes, the content of this specification is referenced to the identical 3GPP TS 23.417 Release 7, ensuring consistency and global compatibility for IMS deployments.
Key Topics
- IMS Core Architecture: Describes how IMS is structured to integrate telecommunications and Internet services across unified networks.
- Functional Entities: Outlines the building blocks and logical components that comprise the IMS core, such as call session control functions and application servers.
- Internal Reference Points: Specifies the interconnections within IMS subsystems necessary for service delivery and management.
- External Interfaces: Details how IMS connects with other network domains and external systems, supporting interoperability and service extensibility.
- Value Added Service Support: Examines mechanisms to deliver advanced multimedia and converged services beyond traditional telephony.
- Network Interconnection: Addresses how the IMS interfaces with other networks and subsystems such as the Network Attachment Subsystem (NASS) and Resource and Admission Control Subsystem (RACS).
The standard significantly references the 3GPP TS 23.417, which prescribes the formal requirements for the IMS functional architecture. As technology and deployments evolve, future changes are governed by updates to the 3GPP specification.
Applications
Implementing SIST ES 282 007 enables telecommunication providers and system integrators to:
- Deploy Next Generation Networks (NGN): Facilitate the migration from legacy systems to all-IP architectures, supporting converged voice, video, and messaging.
- Enable Rich Multimedia Services: Support services such as video calling, presence, instant messaging, and conferencing over a unified IMS platform.
- Ensure Interoperability: Adopt a globally recognized architectural framework, streamlining integration across multi-vendor and cross-domain environments.
- Support Regulatory and Business Requirements: Satisfy demands for lawful intercept, charging, and secure authentication in public and private network scenarios.
- Optimize Network Resources: Utilize standardized interfaces (such as those to NASS and RACS) for efficient resource management and admission control.
By adhering to this standard, operators can achieve increased scalability, service flexibility, and operational efficiency in next-generation telecom environments.
Related Standards
- 3GPP TS 23.417: The definitive technical specification on which this standard is based. Provides complete details regarding the IMS functional architecture and reference points.
- ETSI ES 282 007: The European adoption of the functional architecture for IMS, ensuring alignment with ETSI and TISPAN requirements.
- ETSI TS 123 228: Addresses Service Specific Aspects for the IP Multimedia Core Network Subsystem.
- ETSI TS 129 228 / TS 129 229: Define core IMS elements including Call Session Control Functions (CSCF) and Home Subscriber Server (HSS).
- NGN Framework Standards: Broader standards related to Next Generation Networks from organizations such as ETSI, ITU-T, and 3GPP.
Conclusion
SIST ES 282 007 V1.2.1:2009 serves as a key resource for standardizing IMS functional architecture in modern telecommunications and NGN environments. By referencing 3GPP TS 23.417, it maintains technical parity with global practices and provides a foundation for delivering robust, interoperable multimedia services over integrated digital networks. For organizations involved in deploying or upgrading to IMS-based infrastructures, complying with this standard ensures reliability, future-proofing, and alignment with international best practices.
