Overview

SIST EN 300 918 V7.1.2:2004 specifies the general framework for supplementary services in the digital cellular telecommunications system (Phase 2+), commonly known as GSM (Global System for Mobile communications). Developed by the Slovenski inštitut za standardizacijo (SIST) and aligned with ETSI's EN 300 918, this standard outlines the key concepts, categories, and general mechanisms for the provision, withdrawal, activation, and management of supplementary services, including enhancements such as Follow Me. The document aligns with GSM 02.04 version 7.1.2 (Release 1998), ensuring consistency with international telecommunications practices and providing a basis for network and subscriber service interoperability.

Key Topics

• Supplementary Service Concepts: Defines supplementary services as offerings that modify or enhance standard telecommunication services (teleservices and bearer services) available on GSM networks. These may provide additional convenience, security, or user control.
• Service Lifecycle Processes:
  • Provision and Withdrawal: How a supplementary service is made available or withdrawn from subscribers, either generally or individually.
  • Registration and Erasure: Procedures to input or remove service-related information, enabling or disabling specific options.
  • Activation and Deactivation: Mechanisms for enabling or disabling services, either automatically, by the provider, or at the subscriber's request.
  • Invocation and Interrogation: How a service is triggered (by user or network) or queried for current status/data.
• Categories of Supplementary Services: Includes services related to identity presentation (e.g., CLI), call barring, call forwarding, call waiting, multi-party features, and charging advice.
• Password Control Option: Some services, particularly those affecting call barring, may require password management for added security, with processes for registration, changing, and error handling.
• Framework and Applicability: Explains how supplementary services are associated with different basic services (e.g., speech, SMS, data, GPRS), and how groups of services are managed collectively.

Applications

The standard is essential for:

• Mobile Network Operators: Provides clarity on mandatory vs. optional supplementary services, ensuring consistent service delivery and user experience across networks.
• Service Providers: Facilitates the definition and implementation of enhanced offerings, such as call forwarding, call barring, and identity management (CLI/CLIR), which improve user control and security.
• Equipment Manufacturers: Ensures that handsets and network nodes support the required GSM feature set for service compatibility and international roaming.
• System Integrators & IT Vendors: Supports development, testing, and management tools for telecommunications infrastructure in GSM networks.

Practical examples of supplementary services under this standard include:

• Follow Me: Allows users to redirect calls to different numbers as they move between locations.
• Call Barring: Restricts outgoing or incoming calls under specified conditions (e.g., international calls, calls while roaming).
• Call Forwarding: Redirects calls based on scenarios like no reply, unreachable, or busy signal.
• Multi-party Calls: Enables conference calling features for business and group communication.
• Line and Name Identity Services: Control presentation and restriction of calling line and name information, essential for privacy and business communications.

Related Standards

SIST EN 300 918 V7.1.2:2004 references several key GSM and telecommunications standards, including:

• GSM 02.01, 02.02, 02.03: Core definitions for telecommunication, bearer, and teleservices.
• GSM 02.80 Series: Detailed descriptions of specific supplementary services.
• GSM 03.11, 04.10, 04.80: Technical realization, interface specifications, and coding of supplementary services.
• CCITT Recommendation I.210: General principles of telecommunication services in ISDN.

Other closely related supplementary service specifications include GSM 02.81 (Line Identification), 02.82 (Call Forwarding), 02.83 (Call Waiting and Hold), 02.84 (MultiParty), 02.85 (Closed User Group), and 02.88 (Call Barring).

---

By ensuring standardized handling of supplementary services, SIST EN 300 918 V7.1.2:2004 enables robust, interoperable, and secure delivery of advanced GSM mobile services, supporting both user needs and network efficiency on a global scale.
