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 N1N2, N4, N8, N10, N11, 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 analyze calls in the 5G Network
- Supported protocols include - Non-Access Stratum (NAS), Next Generation Application Protocol (NGAP), Packet Forwarding Control Protocol (PFCP), XnAP, SCTP, UDP, TCP, and IP
- Decode Enhanced Common Public Radio Interface (eCPRI) protocol
- 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)
- 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)
- Save calls to PCAP (Wireshark® format) and in HDL (GL Proprietary format)
- PDA in Packetscan™ provides a complete call flow of a 5G session
- Advanced filtering and search based on any 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
