PFCP Packet Generator Enhancements with 3GPP Notations

1. Robust PFCP Message Generation

The generator now creates a variety of PFCP messages as defined in 3GPP TS 29.244:

  • Association Setup Request/Response (Section 7.4.4)
  • Session Establishment Request/Response (Section 7.5.3)
  • Session Modification Request/Response (Section 7.5.4)
  • Session Deletion Request/Response (Section 7.5.5)
  • Heartbeat Request/Response (Section 7.4.1)

2. Enhanced Information Elements (IEs)

2.1 Node ID (Section 8.2.38)

  • Implemented as IE_NodeId
  • Supports IPv4 addressing

2.2 F-SEID (CP/UP F-SEID, Section 8.2.39)

  • Implemented as IE_FSEID
  • Supports both CP and UP SEID generation

2.3 PDR (Packet Detection Rule, Section 8.2.41)

  • Implemented as IE_CreatePDR and IE_UpdatePDR
  • Includes PDR ID and Precedence

2.4 FAR (Forwarding Action Rule, Section 8.2.42)

  • Implemented as IE_CreateFAR and IE_UpdateFAR
  • Includes FAR ID and Apply Action

2.5 QER (QoS Enforcement Rule, Section 8.2.68)

  • Implemented as IE_CreateQER and IE_UpdateQER
  • Enhanced with:
    • QER ID
    • Gate Status (Section 8.2.69)
    • MBR (Maximum Bitrate, Section 8.2.70)
    • GBR (Guaranteed Bitrate, Section 8.2.71)
    • QFI (QoS Flow Identifier, Section 8.2.89)

2.6 URR (Usage Reporting Rule, Section 8.2.44)

  • Implemented as IE_CreateURR and IE_UpdateURR
  • Includes URR ID and Measurement Method

2.7 Cause (Section 8.2.1)

  • Implemented as IE_Cause
  • Used in response messages to indicate request status

2.8 Recovery Time Stamp (Section 8.2.3)

  • Implemented as IE_RecoveryTimeStamp
  • Used in Association Setup and Heartbeat messages

3. Improved QoS Handling

  • Enhanced QER creation with detailed QoS parameters:
    • Gate Status: Controls gating for uplink and downlink (Section 8.2.69)
    • MBR: Sets maximum bitrate for uplink and downlink (Section 8.2.70)
    • GBR: Sets guaranteed bitrate for uplink and downlink (Section 8.2.71)
    • QFI: Assigns QoS Flow Identifier (Section 8.2.89)

4. Flexible Packet Generation

  • Random generation of SEID, PDR ID, FAR ID, QER ID, and URR ID
  • Customizable source and destination IP addresses for PFCP packets

5. PCAP File Generation

  • Ability to generate multiple PFCP packet pairs and save them to a PCAP file
  • Useful for testing and simulation of PFCP traffic

6. Error Handling and Logging

  • Improved error handling in IE creation and packet generation
  • Detailed logging of packet generation process and any encountered errors

7. 3GPP Compliance

  • Adheres to PFCP message formats and IE structures as defined in 3GPP TS 29.244
  • Supports PFCP protocol version 1 (Section 7.2.1)

8. Extensibility

  • Modular design allows for easy addition of new PFCP message types and IEs
  • Can be extended to support future 3GPP PFCP enhancements

This enhanced PFCP packet generator provides a comprehensive tool for simulating PFCP traffic in accordance with 3GPP specifications, particularly useful for testing and development of 5G core network components.
