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

Overview

SIST-V ETSI/EG 201 720 V1.1.5:2003 provides standardized guidelines for the Universal Mobile Telecommunications System (UMTS) network functional model specifically for IMT2000 networks, in alignment with ITU-T Recommendation Q.1711. Published by the Slovenski inštitut za standardizacijo (SIST) and developed by ETSI, this standard is pivotal for ensuring consistent interpretation and implementation of IMT2000 network functionality within UMTS frameworks.

The document clarifies which elements of the ITU-T Q.1711 recommendation are applicable, supporting European and global stakeholders in understanding nuanced requirements and ensuring interoperability across telecommunication networks.

Key Topics

• UMTS Functional Model Alignment:
  Ensures the network functional model for UMTS family members corresponds with the IMT2000 requirements, based on ITU-T Recommendation Q.1711.

• Scope and Guidance:
  The standard outlines scope, definitions, and exceptions, helping developers and network engineers follow best practices when employing UMTS within the IMT2000 network family.

• Exceptions to ITU-T Q.1711:
  Specifically identifies parts of Q.1711 that are outside the scope of ETSI’s expertise, such as:

  • Cell selection and radio resource management
  • Channel coding and handover processes
  • Paging, compression, and ciphering
  • Packet services and data charging generation
  • Terminal aspects and radio access control

• References and Definitions:
  Includes both specific and non-specific referenced documents, and provides clear definitions for critical terms such as IMT2000 and UMTS, ensuring consistency in terminology and understanding for all implementing parties.

Applications

SIST-V ETSI/EG 201 720 V1.1.5:2003 is essential for:

• Network Planning and Implementation:
  Assists network operators, architects, and mobile telecommunications professionals during the design and deployment of UMTS networks under the IMT2000 umbrella, ensuring conformity to international standards.

• Standardized Interoperability:
  Facilitates seamless integration and interoperability between different vendors’ network elements by providing a unified interpretation of the functional model, reducing ambiguity in multi-vendor environments.

• Technical Specifications Development:
  Acts as a reference for technical committees and working groups involved in drafting or revising telecommunications standards related to mobile communication systems.

• Compliance and Auditing:
  Provides a baseline for regulatory and compliance evaluations, helping organizations verify that UMTS network implementations align with both ETSI and ITU-T recommendations.

Related Standards
