Study Notes
Network Topology Overview
- The network architecture focuses on the PCRF side in the IN Swap project.
- The PCRF test bed is included for network functionality testing.
Physical Connectivity
- OLC (Online Collection Server) serves as the interface between OCS and external network elements.
- Three data types are stored in the database:
- Session Data (session MDB: ODBC): Tracks online subscriber information, including policy in use and session timing.
- Static Data (PCC Rule SHM: Pcache): Contains policy definitions and behavior recognition data.
- Subscription Data (ZSPR: ODBC): Information regarding subscriber profiles and service subscriptions.
Business Process Layer
- Comprises common and customized business process packages with core modules: PDE (Policy Decision Engine) and SPR Proxy.
PDE (Policy Decision Engine)
- Central module in ZSmart Policy Manager that manages policy decisions and session handling.
- Sub-modules include:
- Flow Engine: Drives service processes.
- Session Management: Handles session lifecycle and exceptions.
- Policy Decision: Matches policies to subscriber profiles and events.
- Encoding/Decoding: Manages DCC protocol messages.
- Advice of Policy: Generates notifications for subscribers about policy changes.
- Behavior Analysis: Analyzes subscriber behavior and maps it to events.
PHUB Function Module
- Parses interaction protocols and connects PCRF with other policy-related network elements (e.g., PCEF, BBEF).
UIP Function Module
- SOA-based platform that simplifies protocol integration via adapters.
- Sends notifications for policy changes through UIP.
SPR Data Management
- Manages external SPR Access Proxy and ZSPR data.
Statistical Analysis
- Offers insights through service, alarm, and performance statistics.
System Surveillance
- Functions include:
- Topology management
- KPI collection and monitoring
- Service tracking and testing
- Log management and alarm processing
PCRF Hardware Architecture
- PCRF can adjust bandwidth based on user data usage, increasing or decreasing capacity as needed.
- Flexible policy plans can assign different bandwidths for various services (e.g., 1Mbps for HTTP, 512kbps for FTP).
Quality of Service (QoS) Control Function
- QoS management allows for specific bandwidth allocations; enforced by the PCEF using DPI (Deep Packet Inspection) for service awareness.
Access Control Function
- Gating Control: Restricts user access to certain services or protocols, blocking unauthorized data packets.
- URL Control: Enforces rules based on source/target IP addresses, controlling access to blacklisted websites universally.
