Next-Generation Network Monitoring:
Introducing GL's New 5G Protocol Analyzer

GL is pleased to announce the latest edition of our newsletter, which provides valuable insights into our new 5G protocol analysis tool. GL’s 5G Protocol Analyzer enables real-time monitoring and capture of 5G network traffic, allowing you to effortlessly gather and analyze data across the network.

5G protocol analysis tool


GL's 5G Protocol Analyzer offers comprehensive monitoring capabilities for 5G networks. It captures, decodes, and collects statistics over the N1N2, N4, N8, N10, N11, N12, and N13 interfaces, providing valuable insights into network performance and behavior.

The 5G Protocol Analyzer is an optional application for PacketScan™. PacketScan™ is a protocol analysis software supporting a large range of protocols and codecs. PacketScan™ is deployed on Windows® PCs and uses the host PC’s network interface card to capture Ethernet / IP traffic. The PC should be connected to a network tap or a monitor port on a switch. PacketScan™ can also open packet captures offline and intelligently build call detail records, compute statistics on the calls, create graphs and ladder diagrams and more.

NGAP Layer Decode View

PacketScan™ includes the Packet Data Analysis (PDA) tool allowing users to monitor live IP/TDM networks including capture, analysis, and reporting of every phone call in detail. It also provides graphical presentation of analysis, including ladder diagrams of call flows.

    • N4 Interface - Session Management Function (SMF) and User Plane Function (UPF) elements
    • N8 Interface - Unified Data Management (UDM) and Access and Mobility Management Function (AMF)
    • N10 Interface - Unified Data Management (UDM) and Session Management Function (SMF)
    • N11 Interface - Mobility Management Function (AMF) and Session Management Function (SMF)
    • N12 Interface - Authentication Server Function (AUSF) and Access and Mobility Management Function (AMF)
    • N13 Interface - Authentication Server Function (AUSF) and User Data Management (UDM)
  • Supported protocols include Non-Access Stratum (NAS), Next Generation Application Protocol (NGAP), Packet Forwarding Control Protocol (PFCP), Xn Application Protocol (XnAP), SCTP, UDP, TCP, and IP
  • Decode Enhanced Common Public Radio Interface (eCPRI) protocol

  • PDA in Packetscan™ provides a complete call flow of a 5G session
  • Advanced filtering and search based on user selected protocol fields
  • Add any protocol field to the summary view, filtering, and search features. This flexibility allows users to monitor the specific protocol fields they need
  • Trigger intelligent actions based on signaling and traffic conditions
  • Displays Summary, Detail, Hex dump, Statistics, and Call Detail Views
  • Hex dump View displays the frame information in HEX and ASCII format, the contents of this view can also be copied to clipboard
  • Statistics View displays statistics based on frame count, byte count, frames/sec, bytes/sec etc. for the entire capture data
  • Call Detail View displays called / calling number, released calls, call status, and more
