Overview

SIST EN 300 955 V7.0.1:2003 defines the procedures for implementing Advice of Charge (AoC) supplementary services in the digital cellular telecommunications system (GSM Phase 2+), aligned with the GSM 04.86 version 7.0.1 (Release 1998) standard. Developed by SIST and based on ETSI specifications, this standard ensures accurate management and communication of charging information between mobile subscribers and networks in the GSM environment. AoC functionality is essential for both mobile operators and users, enabling transparency of call costs and supporting enhanced billing processes within GSM systems.

Key Topics

• Advice of Charge (AoC) Supplementary Services
  • AoC Information (AoCI): Provides real-time charging information to mobile stations (MS) after successful service requests.
  • AoC Charging (AoCC): Enables the MS to calculate costs based on real-time advice from the network for each applicable service.
• Normal and Abnormal Operation
  • Supports both MS-originated and MS-terminated calls with relevant charging information exchange.
  • Handles radio link failures and ensures accurate chargeable duration management.
  • Specifies procedures if charging responses are not properly acknowledged.
• Service Procedures
  • Procedures at the GSM radio interface (Um) for the transfer of charge information, including set-up, notification of changes, and clearing of calls when thresholds are met.
  • Clarifies that activation, deactivation, interrogation, registration, and erasure of AoC services are not applicable at the radio interface and remain administrative between subscriber and service provider.
• Alignment with Release 1998
  • Incorporates enhancements and corrections from earlier releases, supporting interoperability and service consistency in modern GSM networks.

Applications

The Advice of Charge (AoC) supplementary services are crucial for:

• Mobile Operators:
  • Automating billing processes by delivering real-time charging information directly to the mobile user.
  • Enhancing customer service through transparency of call and service charges.
  • Managing network resources and improving engagement with prepaid and postpaid customers.
• End Users:
  • Monitoring cellular usage by receiving up-to-date charge details for each completed call or session.
  • Making informed decisions about ongoing call costs, leading to reduced billing disputes and better cost control.
  • Supporting multiparty and special call scenarios by providing individualized charging data.
• System Integrators and Equipment Vendors:
  • Ensuring consistent GSM feature implementation across devices and network infrastructure.
  • Facilitating interoperability with international standards for value-added billing and customer information services.

Related Standards

Several standards are referenced for the implementation and operation of AoC services within GSM networks:

• GSM 04.02 - GSM Public Land Mobile Network (PLMN) access reference configuration
• GSM 04.08 - Mobile radio interface Layer 3 specification
• GSM 02.24 & GSM 03.86 - Description and technical realization of charge advice information services
• GSM 02.86 & GSM 03.86 - AoC supplementary services
• GSM 04.10 and GSM 04.80 - General aspects and coding for supplementary services
• GSM 01.04 - Abbreviations and acronyms for digital cellular telecommunications

Practical Value

Implementing SIST EN 300 955 V7.0.1:2003 strengthens GSM network billing accuracy, enhances customer trust, and aligns network operations with internationally recognized practices for digital cellular telecommunications. The standard ensures that both mobile networks and users benefit from real-time, transparent charging mechanisms, supporting efficient telecom service delivery and regulatory compliance.
