Call Trace / Protocol Analysis

NexusNETVIEW offers centralized online Call Tracing and Protocol Analysis features based on Communication Detail Records (CDRs). NexusNETVIEW captures and correlates signalling data from protocol stacks such as:

• GSM (MAP, CAMEL, SS7)
• GPRS (Gx protocol)
• UMTS (Iux)
• PSTN (TCAP, ISUP, SS7, INAP, ISDN PRA)
• VoIP (SIP, H.323, H.248, MGCP, RTP)
• NGN (SIGTRAN, BICC)
• CDMA (IS-41, IOS)
• W-LAN

End-to-End Call Tracing

NexusNETVIEW simultaneously monitors and stores all signalling activities in your wireless and/or wireline network(s). Raw signalling data collected from the NexusNETVIEW probes are correlated on-line across the network and stored as individual CDRs, which can be immediately retrieved and visualized. Comprehensive centralized/remote protocol analysis features allow very fast in-depth analysis of call flow and protocol details.

CDR Creation "on-the-fly"

NexusNETVIEW continuously captures all signalling activities and creates corresponding records for each communication leg (CLR - Communication Leg Record). For each End-to-End signalling transaction, all participating CLRs are correlated and grouped into a single CDR. NexusNETVIEW creates CDRs for communication transactions such as:

• Voice calls (PSTN, Mobile, VoIP, NGN)
• Messaging (SMS, MMS)
• Location updates (mobile networks)
• Data sessions (GPRS, UMTS, W-LAN)

Call Flow and Protocol Analysis

For each CDR, the event sequence chart visualizes the signalling call flow and all participating CLRs. Thus, calls can be followed from a single workstation in every detail through all network interfaces, including the DSS1-Interface, the A-Interface and multiple IN and HLR queries — all within one single CDR. Moreover, NexusNETVIEW's powerful built-in Protocol Analyzer enables visualization of CDR details — for all individual protocols!

NexusNETVIEW is highly scalable, allowing proven cost-effective and vendor-independent signaling surveillance for all networks, small, medium and large — with transaction rates of up to several hundred million CDRs per day. Even with huge CDR data collections, intelligent multi-criteria search algorithms allow for CDR searching and retrieving within seconds.
