5G Protocol Analyzer

Overview

5G is a fifth-generation mobile technology for cellular networks. 5G covers three main verticals namely, Enhanced Mobile Broadband (eMBB), Massive Machine Type Communications (mMTC), and Ultra Reliable Low Latency Communications (URLLC) to support a wide variety of use cases such as Smart cities, AR/VR, self-driving cars, IoT etc.

GL’s PacketScan™ 5G protocol analyzer supports monitoring of 5G networks. It captures, segregates, monitors, and collects statistics on all calls over N1/N2, N4, N8, N12 and N13 interfaces of the 5G network. GL's 5G Protocol Analyzer is an optional module (PKV112) available within PacketScan™ on purchase of additional licensing.

Main Features

• Capture, Decode, and Analysis of Calls in 5G Network
• Supported protocols - Non-Access Stratum (NAS), Next Generation Application Protocol (NGAP), Packet Forwarding Control Protocol (PFCP), XnAP, SCTP, UDP, TCP, and IP
• Following interfaces are supported in Packet Data Analyzer:
• N1 N2 Interface - gNodeB (also called Next Generation RAN), and AMF (Access and Mobility Management Function) nodes
• 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)
• N12 Interface - Authentication Server Function (AUSF) and Access and Mobility Management Function (AMF)
• N13 Interface - Authentication Server Function (AUSF) and User Data Management (UDM)
• Interested calls can be saved to PCAP (Wireshark® format) and in HDL (GL Proprietary format)
• Packet Data Analyzer feature in Packetscan™ provide a complete call flow of a 5G session
• Advanced filtering and search based on any user selected protocol fields
• Any protocol field can be added to the summary view, filtering, and search features providing users more flexibility to monitor required protocol fields
• 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
• Provides a consolidated interface for all the important settings required in the analyzer. All the configuration settings done in any of these options can be saved to a file, loaded from a configuration file
