kSIST prES 283 012 V2.0.1:2010

Overview

kSIST prES 283 012 V2.0.1:2010 focuses on standardizing interworking control procedures between Next Generation Networks (NGN) and external Circuit-Switched (CS) networks. Developed by SIST and endorsed from ETSI ES 283 012, this standard is based on the well-established 3GPP TS 29.412 (Release 8), ensuring compatibility with international telecommunication protocols. The specification is part of the TISPAN (Telecommunications and Internet converged Services and Protocols for Advanced Networking) framework and primarily addresses trunking gateway control mechanisms to facilitate seamless service between NGN and legacy PSTN/ISDN CS networks.

Key Topics

• Interworking Procedures: The document delineates how trunk gateways should be controlled to manage calls and signaling when NGN-based networks interact with external CS environments using ISUP protocols.
• Trunking Gateway Control: Specification of control mechanisms needed for PSTN/ISDN emulation and simulation services within NGN architectures.
• Scope Limitations: The focus is on ISUP-based interworking; BICC (Bearer Independent Call Control) network interworking is not included.
• Adoption of International Standards: The standard closely mirrors 3GPP TS 29.412, with modifications tailored to TISPAN NGN R2 requirements.
• Reference Management: Provides guidelines for maintaining alignment with normative and informative referenced documents, ensuring applicability and up-to-date integration in evolving networks.

Applications

Implementing this standard yields significant benefits for telecommunications operators and equipment vendors, including:

• Seamless Integration: Facilitates the convergence and interoperability of NGN with legacy PSTN/ISDN networks, enabling operators to offer comprehensive voice services as networks transition to all-IP architectures.
• Gateway Deployment: Assists vendors in designing gateway devices that ensure proper signaling translation, call setup, and control between IP-based NGN and circuit-switched domains.
• Service Continuity: Ensures end-users experience no disruption in voice and supplementary services during migration from traditional TDM-based telephony to modern NGN services.
• Regulatory Compliance: Aligns with industry-wide practices and expectations, supporting operators' compliance with national and international telecommunication regulations.
• Network Modernization: Enables phased legacy system upgrades, providing a clear migration path and investment protection for existing infrastructure while adopting advanced networking capabilities.
