Overview
SIST EN 300 927 V5.3.1:2003 is a Slovenian national adoption of the European Standard EN 300 927 (GSM 03.03 version 5.3.1 Release 1996). This standard, developed by ETSI, focuses on the Digital Cellular Telecommunications System (Phase 2+) (GSM), addressing critical aspects such as numbering, addressing, and identification within GSM networks. The document provides the framework for identifying mobile subscribers, equipment, network elements, and services-ensuring efficient global system for mobile communication operation and interoperability.
Key Topics
This standard covers several essential topics related to GSM networks:
- Subscriber Identification: Rules for the allocation and composition of the International Mobile Subscriber Identity (IMSI), Temporary Mobile Subscriber Identity (TMSI), and Local Mobile Station Identity (LMSI) to uniquely identify subscribers in GSM networks.
- Numbering Plan: Definitions and structures for assigning telephone and ISDN numbers to mobile stations (MS), including MSISDN (international PSTN/ISDN number), Mobile Station Roaming Number (MSRN), and data numbering (X.121).
- Location and Equipment Identification: Detailed structure for identifying location areas, base stations, MSCs (Mobile Switching Centers), and location registers using elements such as Location Area Identification (LAI), Cell Global Identification (CGI), and International Mobile Station Equipment Identity (IMEI).
- Group and Broadcast Services: Identification schemes for subscribers and areas involved in Voice Group Call Service (VGCS) and Voice Broadcast Service (VBS).
- SCCP Subsystem Numbers: Specification of subsystem numbers for signalling connection control part (SCCP) applications, including handling of CAP (CAMEL Application Part).
- Addressing Requirements: Principles for numbering plans that permit roaming, call routing, and efficient subscriber management across national and international GSM networks.
Applications
The standard is indispensable for several stakeholders in the mobile telecommunications sector:
- Mobile Network Operators: Ensures proper network configuration, management of subscriber identities, and seamless interworking with external networks (e.g., PSTN, ISDN, and other GSM PLMNs).
- Equipment Manufacturers: Guides the design and implementation of network components and mobile devices to conform to global GSM identification and numbering protocols.
- Systems Integrators: Supports planning for scalable and interoperable mobile communication solutions by enabling effective numbering, addressing, and location coding.
- Regulators and Administrations: Provides a foundation for national and international number allocation and helps prevent subscriber and network identifier conflicts.
- Roaming and Service Provision: Enables roaming services, call routing, and management of temporary and permanent subscriber identities, supporting features such as handover and location updates.
The use of clear identification systems improves network security, privacy, and user experience by ensuring accurate call delivery and data routing.
Related Standards
SIST EN 300 927 V5.3.1:2003 references, aligns with, and is complemented by several other standards, including:
- GSM 01.04: Abbreviations and acronyms.
- GSM 03.08: Organization of subscriber data.
- GSM 03.20: Security-related network functions.
- GSM 03.70: Routing of calls to/from Public Data Networks (PDN).
- GSM 04.08: Mobile radio interface Layer 3 specification.
- GSM 09.03: Signalling requirements for interworking between ISDN/PSTN and PLMN.
- GSM 11.11: Subscriber Identity Module-Mobile Equipment (SIM-ME) interface specification.
- CCITT Recommendations: E.164 (ISDN numbering plan), E.212 (identification plan for land mobile stations), E.213 (telephone/ISDN numbering plan for PLMNs), X.121 (international numbering for public data networks).
These related standards collectively ensure end-to-end compatibility and global interoperability of GSM networks.
