ECP-333 Ericsson Associate - Charging Mock Tests

ECP-333: Ericsson Charging Exam Blueprint1. Architecture and Solution ComponentsOverview of Convergent Charging: Principles of unified online and offline charging, real-time balance control, and the role of the Online Charging System (OCS) in modern telecom (4G/5G/IoT) Business Support Systems (BSS).Ericsson Charging System Architecture: Deep dive into internal modules, subsystems, and their deployment roles (including cloud-native deployment patterns using Kubernetes).Integration Components: Exploring functional interactions between Account Management, Rating Engines, and Session Control components.External Integration Landscapes: Understanding how Ericsson Charging connects with Telecom Operator IT landscapes including CRM (Customer Relationship Management), Billing Systems, ERP, and Self-Service apps. 2. Traffic Management Network InterfacesStandard Protocols and Reference Points:Diameter Protocol: Understanding Credit Control Application (CCA), Ro/Gy interfaces for 4G charging, and Sy interface for policy counter checks.5G Service-Based Architecture (SBA): Deep dive into HTTP/2-based protocols, specifically the Nchf convergent charging service interface.Alternative and Legacy Interfaces: Overview of CAP (CAMEL Application Part), MAP, and web-services-based APIs (REST/SOAP) for multi-generation network support.Session Management Traffic Flow: Real-time routing of credit control requests, reservation mechanisms (Quotas, Units, and Validity time), and final termination/commit requests.3. Catalog and Policy ManagementProduct Catalog Fundamentals: Structuring product offerings, commercial monetization definitions, and mapping business requirements into technical parameters.Dynamic Tariffs and Rating Logic: Configuring complex pricing trees, time-of-day/day-of-week tariffs, volume/duration rating, step-based pricing, and zone-based configurations.Unified Policy Control: Core concepts of decoupling policy from network nodes; integration with PCRF/PCF for real-time bandwidth throttling, speed bur
