Overview
SIST EN 301 254 V1.1.1:2005 defines the stage 1 and stage 2 specifications for the Advice of Charge (AoC) supplementary services within Private Integrated Services Networks (PISN). This standard modifies and aligns with ISO/IEC 15049:1997, providing a European context for implementing AoC within PISNs. It is developed by the Slovenian Institute for Standardization (SIST) and based on EN 301 254, focusing on the transport of public ISDN information within private networks. AoC supplementary services enable users to receive essential information about call charges, supporting cost transparency and control in corporate telecommunication environments.
Key Topics
-
Advice of Charge (AoC) Supplementary Services
The standard outlines the requirements for providing charging information to users, either during a call (real-time) or after the call ends.
-
Functional Models and Information Flows
It establishes functional models, information flows, and roles within the PISN architecture to ensure effective communication and charge notification.
-
Compatibility and Modifications
SIST EN 301 254 V1.1.1:2005 modifies several references from ISO/IEC standards to their European equivalents, facilitating regional interoperability.
-
PISN and ISDN Integration
The standard supports the seamless transport of ISDN-based charging information within private networks, maintaining compatibility with public ISDN networks.
-
Stage 1 and Stage 2 Descriptions
- Stage 1: High-level service requirements and user-oriented service descriptions for AoC services.
- Stage 2: Functional analysis detailing the information flow and interactions between network components.
Applications
Implementing AoC supplementary services in a Private Integrated Services Network brings several practical benefits:
-
Cost Management
Organizations can provide users with immediate or periodic information on call charges, enabling informed decision-making and resource management.
-
Billing Accuracy
Accurate, real-time charging information helps both users and administrators monitor and verify telecom costs within private enterprise environments.
-
Transparency for End Users
Real-time advice of charge notifications increase user awareness and trust in network services by providing clear, understandable cost information.
-
Corporate Telephony Networks
Businesses operating their own telephony infrastructure (PISN) can align internal charge notification with external ISDN billing standards for unified user experiences.
-
Enhanced Network Services
Supporting AoC services adds value to private network offerings and ensures compliance with international and European best practices in telecommunication management.
