Overview

SIST EN 300 940 V7.7.1:2005 specifies the Layer 3 protocol for the mobile radio interface in the digital cellular telecommunications system (GSM Phase 2+). This European standard is identical to EN 300 940 Version 7.7.1, originating from the GSM 04.08 version 7.7.1 Release 1998 specification. It serves as a critical building block for enabling mobile communications across GSM networks by defining control procedures, message structures, and protocols used between mobile stations and network infrastructure.

This standard is managed by the Slovenski inštitut za standardizacijo (SIST) and falls under the International Classification for Standards (ICS) code 33.070.01, relating to mobile services in general. The document supports the implementation and interoperability of GSM networks, facilitating digital cellular telecommunications systems within Europe.

Key Topics

• Mobile Radio Interface Layer 3: Defines the procedures and messages for managing communication between mobile devices and the GSM network at the third layer of the OSI model.
• Radio Resource Management: Procedures for establishing, maintaining, and releasing radio connections including handovers, channel assignments, and paging.
• Mobility Management: Handles business logic for subscriber mobility, including location updating, registration, and roaming support within GSM networks.
• Logical Channel Usage: Clarifies the use of logical channels and their impact on mobile service delivery.
• Control Procedures: Includes elementary and compound procedures for connection management, authentication, and ciphering modes.
• Support for Advanced Services: Addresses support for features such as General Packet Radio Service (GPRS), Voice Group Call Service (VGCS), and Voice Broadcast Service (VBS).

Applications

SIST EN 300 940 V7.7.1:2005 is foundational for:

• Network Operators: Ensuring GSM base stations and mobile switching centers operate in compliance with established procedures for seamless connection setups, handovers, and disconnections.
• Equipment Manufacturers: Designing and testing mobile devices, base station subsystems, and network infrastructure to guarantee interoperability within GSM digital cellular systems.
• Roaming and Interoperability: Supporting cross-network roaming by standardizing messaging and network behaviors, making mobile communication possible across different operators and regions.
• Enhanced Mobile Services: Building stable platforms for services like GPRS data, group calling, broadcast services, and emergency communication.

The standard enables reliable and secure transmissions in digital cellular networks, providing the basis for supporting subscriber mobility, call management, resource allocation, and advanced GSM services.

Related Standards

To ensure full conformity and interoperability within GSM and related mobile systems, the following standards are commonly referenced alongside SIST EN 300 940 V7.7.1:2005:

• ETSI EN 300 940: The European equivalent, harmonized across member states for unified implementation.
• GSM 04.08: The core technical specification describing Layer 3 procedures in GSM networks.
• GSM 03.03: Addresses numbering, addressing, and identification features within GSM.
• GSM 04.07 / GSM 04.10: Define lower layers supporting the radio interface-crucial for protocol stack integrity.
• GSM 04.60: Focuses on GPRS-a key enhancement to support packet-switched data in GSM networks.

Adhering to SIST EN 300 940 V7.7.1:2005 is essential for organizations involved in mobile GSM systems development, operation, and certification, ensuring high-quality, compatible, and secure mobile telecommunications services.
