VoLTE is a good example of a service that requires comprehensive end-to-end support. For this reason, TravelHawk Pro supports the full LTE control-plane signaling analysis of VoLTE sessions. It identifies the user identifications (IMSI/PSTN/IMEI), network locations (TAC/APN/etc.) and all signaling-related problems from S1-MME, S6a, S11 and other interfaces. Essentially, it ensures the very fast detection of VoLTE calls, specific users and erroneous calls.
TravelHawk Pro also offers the one-click correlation of LTE and SIP/RTP sessions as well as information over S1-U, S5/8, Sgi, etc. The user plane can be drilled down to show all the SIP/RTP-related session information, including caller ids and media types, as well as quality of service (QoS) values like mean opinion score (MOS). TravelHawk Pro will directly drill down from the sessions to the message flow and details. This view shows every session-related message from the control-plane interfaces as well as the related SIP/RTP messages for deep root-cause analysis. Finally, the Voice Playback option makes it possible to listen to phone conversation
LTE, Statistics to the Details
Network level issues from the user plane and LTE signaling interfaces can be seen in statistical views, making failed sessions easy to troubleshoot. They can even be filtered according to failure type or network element. From any KPI level, the user can drill down to the failed sessions themselves to discover if they were caused by the same subscriber or by the mobile type, for example. A detailed network analysis of the session can be activated in one click in the Message Sequence Chart view, providing the technician with the detailed information needed to identify the root cause.
TravelHawk Pro is the ideal tool for telecom and IT professionals requiring a high-performance, data capture and processing unit for 1 and 10 Gbit/s Ethernet networks. Data is captured in a nanosecond PCAP format, which is an open standard that any tool can use. Full line-rate packet filtering and processing is supported—for multiple 10 Gbit/s Ethernet interfaces—regardless of packet size. TravelHawk Pro offers a line-rate data-analysis capability with hardware filters and up to 20 Gbit/s sustained capturing to local storage
IP Application Data Analysis
TravelHawk Pro can post-process all-IP, transmission-level or tunneled-level (mobile IP) flows thanks to its powerful IP application analysis engines. It also displays all basic TCP/IP-level problems. The comprehensive, automatic detection and analysis of almost any application (Skype, Facebook, emails, etc.) and its details gives full visibility of the user experience at the application level. Combined with the industry’s leading LTE/EPC analysis support, TravelHawk Pro makes troubleshooting subscriber QoE easier than ever. Find subscribers in seconds using IMSI/GUTI or any other indicator, and observe the signaling experience. Plus, one click is all it takes to see the throughput of every application and other QoS values from the subscriber’s LTE packet connection.
