Overview

SIST EN 301 715 V7.0.2:2003 defines the Stage 1 service description for the Support of Mobile Number Portability (MNP) within GSM networks in a single country. Based on the GSM 02.66 version 7.0.2 Release 1998, this standard establishes the requirements and high-level functional scope allowing mobile subscribers to retain their existing MSISDN (Mobile Station ISDN numbers) when switching between different GSM network operators nationally. The document is highly relevant to network operators, service providers, equipment manufacturers, and regulatory bodies involved in the implementation and management of mobile telecommunications.

Key Topics

• Mobile Number Portability (MNP) Definition
  MNP is the ability for a mobile subscriber to change their GSM subscription network within a country while keeping their original mobile number (MSISDN).

• Stakeholders Covered

  • GSM network operators (PLMN operators)
  • Service providers
  • Equipment manufacturers (terminals, switches, databases)
  • Regulatory and standards bodies

• Core Requirements

  • Porting is limited to GSM networks within a country.
  • Porting is applicable to services identified by an MSISDN (e.g., voice, SMS, data).
  • The process does not include number portability between fixed and mobile networks.
  • The porting process requires network administrative actions rather than end-user handset commands.
  • The technical solution should minimize service disruption and additional call setup delay.
  • Recipient networks must provide service to ported numbers like any regular subscriber.
  • Supplementary and value-added services for ported subscribers should match those for non-ported subscribers.

• Exclusions

  • Charging principles and tariffs, except where specified.
  • Human interface or MMI details.
  • Service provider portability not involving a network change.
  • Relationships between service providers, operators, and end-users outside of MNP.

Applications

• Subscriber Retention and Choice
  MNP empowers end-users to switch GSM network operators without losing their established mobile number, reducing barriers to operator competition and improving consumer freedom.

• Industry Impact

  • Network Operators are required to implement administrative and technical mechanisms for seamless porting, ensure consistent service availability, and optimize routing for ported numbers.
  • Service Providers must coordinate with multiple GSM operators to facilitate number porting in compliance with national regulations.
  • Regulatory Authorities rely on this standard to promote fair market practices, enhance consumer rights, and ensure interoperability across different operators.

• Technical Implementation

  • Involves updating network elements in donor and recipient networks.
  • New IMSI and SIM assignment by the recipient network is required for each ported MSISDN.
  • No difference in supplementary service handling (e.g., call forwarding, call waiting, call barring) for ported subscribers.
  • Efficient mechanisms for exchanging porting information among all participating operators.

• Lawful Interception Compliance
  Lawful interception must remain feasible post-porting, ensuring adherence to national security and legal requirements.

Related Standards

• GSM 01.04 (ETR 350) - Abbreviations and acronyms relevant to GSM and MNP.
• EN 301 715 (various versions) - European Norm for digital cellular telecommunications related to MNP.
• Supporting Documents
  • European Commission and ETSI studies on number portability and equal access.
  • Technical Feasibility Studies and high-level descriptions from the Number Portability Task Force.

This standard, recognized across Europe, ensures the reliable and interoperable implementation of mobile number portability within GSM networks, supporting competitive telecommunications markets and improving subscriber satisfaction. For organizations planning mobile network upgrades or regulatory compliance, meeting the guidelines in SIST EN 301 715 V7.0.2:2003 is essential to ensure seamless service continuity and legal conformity in the national GSM environment.
