GL Communications Inc., a provider in telecom test and measurement solutions, addressed the press regarding their new 5G protocol analysis tool. GL’s 5G protocol analyser enables real-time monitoring and capture of 5G network traffic, allowing to gather and analyse data across the network.
“GL’s 5G Protocol Analyser 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,” says Vijay Kulkarni, CEO of GL Communications.
The 5G protocol analyser 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 (internet protocol) 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.
PacketScan includes the Packet Data Analysis (PDA) tool allowing users to monitor live IP/TDM (time-division multiplexing) 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.
Key features
- Capture, decode, and analyse calls in the 5G network
- Supported interfaces:
- N1N2 interface – gNodeB [also called next generation RAN (radio access network)], 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)
- Supported protocols include non-access stratum (NAS), Next Generation Application Protocol (NGAP), Packet Forwarding Control Protocol (PFCP), Xn Application Protocol (XnAP), SCTP (stream control transmission protocol), UDP (user datagram protocol), TCP (transmission control protocol), and IP
- Decode enhanced Common Public Radio Interface (eCPRI) protocol
- Displays summary, detail, hex dump, statistics, and call detail views
- 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
