SIST EN 301 827 V1.1.1:2005

• Abstract:

  ANF-WTMI is a feature that directs incoming calls to a WTMI user within the PISN regardless of the WTMI user's geographical location within the PISN, provided that the WTMI user's location is known. Roaming outside the PISN is outside the scope of this edition of this standard. ANF-WTMO permits the PISN to process call requests from a WTMO user at the Home mocation, if required.

Overview

SIST EN 301 827 V1.1.1:2005 defines the inter-exchange signalling protocol for Private Integrated Services Networks (PISN), focusing on wireless terminal call handling through additional network features (ANF). Based on and modifying ISO/IEC 15431:2003, this standard is essential for organizations deploying and managing PISNs with wireless terminal mobility. The protocol, a part of QSIG (PSS1 protocol), delivers unified call routing and handling for wireless users within a private network, significantly enhancing mobility and flexibility.

The standard is published by the Slovenski inštitut za standardizacijo (SIST) and aligns with international practices laid down by ETSI and ISO/IEC.

Key Topics

• Wireless Terminal Mobility: ANF-WTMI enables the routing of incoming calls to users with wireless terminals anywhere within the PISN, provided their location is known in the network.
• Home Location Call Processing: ANF-WTMO allows call requests from wireless terminal users to be handled at their home location within the network.
• Protocol Integration: The signalling protocol described supports integration at the Q reference point in PISN networks, ensuring compatibility with existing digital and ISDN-based system architectures.
• Exclusions: The standard’s scope is limited to mobility within the PISN; roaming outside of the private network is not addressed in this edition.
• Reference Modifications: Modifications to the original ISO/IEC standard ensure compliance and harmonization with related European standards and terminologies.

Applications

• Enterprise Networks: Organizations with large or distributed office campuses benefit from unified wireless terminal mobility, allowing staff to move freely and stay accessible across network sites.
• Private Telecommunications Infrastructure: Facilitates seamless voice communications for private or corporate users, maintaining call continuity as users roam within the private network boundaries.
• System Integration: Manufacturers and integrators use this protocol to ensure their PISN connected devices and wireless terminals can handle calls according to standardized methods, supporting interoperability in multi-vendor environments.
• Service Provisioning: Telecom service providers operating or managing private networks use the specified protocol to deliver value-added mobility features to clients.
• Future Scalability: The standard supports future expansion of network features as PISN evolves, allowing upgrades and extensions without compromising existing service quality or interoperability.

Related Standards

For comprehensive coverage and effective implementation, the following standards are relevant and complementary to SIST EN 301 827 V1.1.1:2005:

• EN 301 826: Specification, functional model, and information flows for wireless terminal handling in PISN.
• EN 300 189: Addressing schemes within Private Integrated Services Networks.
• EN 300 172: Circuit-mode basic services inter-exchange signalling.
• EN 300 239: Generic functional protocol for supplementary services support.
• EN 301 255: Protocol for message waiting indication.
• EN 301 264: Advice of charge supplementary services.
• EN 300 257: Call diversion supplementary service.
• EN 300 238: Name identification supplementary service.

These related standards enhance interoperability, ensure compliance with international best practices, and facilitate robust PISN operation in diverse enterprise and private telecommunication settings.
