Overview
SIST EN 301 657 V1.1.1:2005 is a European standard developed by the Slovenski inštitut za standardizacijo (SIST) and aligned with the European Telecommunications Standards Institute (ETSI) framework. This standard defines the specification, functional models, and information flows for Private Integrated Services Networks (PISN), specifically focusing on Private User Mobility (PUM) and Call Handling Additional Network Features (ANFs). The document combines earlier stage 1 and 2 descriptions into a single, harmonized standard and aligns with stage 3, providing a unified approach to mobility and call management in private networks.
The standard is based on a modified version of ISO/IEC 17877:2000 and is part of a broader series addressing services and signaling protocols for PISN environments, reflecting both ISDN and Open Systems Interconnection (OSI) concepts.
Key Topics
- Private Integrated Services Network (PISN): Definition and structure for private telecommunication networks integrating digital services.
- Private User Mobility (PUM): Models and provisions enabling users to move freely within a network while maintaining service continuity.
- Call Handling Additional Network Features (ANFs): Specification of advanced telephony features that support enhanced call control and routing for users on the move.
- Functional Models and Information Flows: Detailed description of processes and data exchanges that underpin PUM and ANFs within PISN.
- Alignment with International Standards: Modifications and references to ensure compatibility with ISO/IEC 17877 and other related standards.
- Scope Harmonization: Consolidating previous development stages for a consistent and efficient standard applicable across European private telecommunication networks.
Applications
SIST EN 301 657 V1.1.1:2005 provides practical guidance and frameworks for:
- Enterprise Communication Systems: Enhancing the flexibility of corporate telephony infrastructures by supporting user mobility and advanced call management in private networks.
- System Integration: Enabling vendors and integrators to develop interoperable products within the PISN environment, ensuring seamless communication across platforms.
- Service Providers: Facilitating the deployment of supplementary services such as call forwarding, routing, and location registration for businesses needing high mobility and advanced network features.
- Telecommunication Network Planning: Supporting network engineers and architects in designing PISN systems that leverage the standardized models for increased scalability and service continuity.
