Overview
SIST EN 301 464 V1.1.1:2005 is a European standard that defines the interactions between the Integrated Services Digital Network (ISDN) Signalling System No.7 (SS7) ISDN User Part (ISUP) version 4 and the Intelligent Network Application Part (INAP), specifically based on ITU-T Recommendation Q.1601 (1999), as modified. This standard is crucial for operators and service providers implementing intelligent network (IN) capabilities over ISDN infrastructures, facilitating advanced services by ensuring reliable interoperability between ISUP and INAP within ISDN networks.
The document outlines protocols that enable the exchange of signalling information via Network-to-Network Interfaces (NNI), supporting modern telecommunication services and supplementary features within the framework of ISDN and intelligent network operations.
Key Topics
- ISUP-INAP Interactions: Describes procedures and protocols that allow the ISDN User Part to interact efficiently with the Intelligent Network Application Part, ensuring seamless support for IN services in ISDN environments.
- Call Control for IN Calls: Details specific call control functions for handling intelligent network calls, including call set-up, release, and supplementary service processing.
- Protocol Enhancements: Defines protocol elements and compatibility mechanisms enabling stepwise upgrades of ISUP functionalities to meet evolving intelligent network requirements.
- Parameter Mapping: Specifies how parameters exchanged between ISUP messages and INAP operations should be mapped to maintain correct service logic and signaling flow.
- Limitations and Network Considerations: Notes certain constraints, such as considerations for SS7 nodes at the transit level and implications for ISDN supplementary services.
Applications
The standard delivers practical business value for:
- Telecom Operators and Service Providers: Enables efficient integration of IN services, such as toll-free calling, advanced call routing, and custom calling features, within existing ISDN infrastructures.
- Network Equipment Manufacturers: Serves as a specification guide for developing SS7 and INAP compatible hardware and software, ensuring products meet interoperability and regulatory expectations within ISDN networks.
- Network Engineers and Planners: Provides a reference for implementing, maintaining, and troubleshooting ISUP-INAP interactions, supporting seamless delivery of value-added services.
- Regulatory Compliance: Ensures that network implementations adhere to European norms regarding signaling and service interworking for ISDN and intelligent networks.
Typical use cases include:
- Launching and managing advanced telecommunication services (e.g., number translation, call screening, call transfer) via intelligent network applications over the ISDN signaling backbone.
- Enhancing service logic by mapping user- and network-specific parameters between ISUP and INAP, supporting robust supplementary service operation.
- Facilitating stepwise network upgrades without service disruption, leveraging the protocol’s inherent compatibility features.
