NetScan in brief


  • Real-time, continuous mobile network monitoring, processing and data analysis.

     

  • Covers 2G RAN (A, Abis, Gb) and selected 3G RAN (IuCS, IuPS, Iub and Iur) and LTE (S1- MME) interfaces.

     

  • Shared-RAN (MOCN & MORAN) support including secure separation of data between MNO’s involved.

     

  • Reach set of pre-defined KPI’s (CSSR, CSTR, etc.) aggregated per cell, project, region and BSC/RNC, and cluster of cells.

     

  • Real-time KPI monitoring and alarming per cell and BSC/RNC.

     

  • Real-time monitoring of QoE and alarming per VIP subscriber (High Value Account).

     

  • Network-wide session analysis (e.g. calltracing) with message correlation.

     

  • Message decoding down to bit level.

     

  • Open architecture ready to deploy new features (integration with external systems like data warehouse, CEM, etc.).

     

  • Support for Gn interface (User and Control Plane monitoring with Deep Packet Inspection and Classification).

     

  • Planned for 2017: 
    • Advanced eUTRAN analysis (based on radio-related traceport data for major vendors). 
    • Advanced Geo-location. 
    • Advanced algorithms to support radio-planning (HO relations optimisation, coverage analysis, geo-service analysis).

System Architecture


  • Highly distributed, scalable system architecture to cope with high load.

     

  • Network signalling monitored through a chain of smart TAP’s feeding local servers with pre-filtered data.
  • Captured PDU’s are decoded and processed to calculate KPI’s and  correlate on various Levels.

     

  • Supports multi-interface correlation, including inter-BSC and inter-system handovers.

NetProbe


  • 40 inputs 1 GbE optical (splitter 80/20, 20 pairs).

     

  • 5 outputs (1 x 1GbE copper, 4 x 10/1GbE).

     

  • HW/SW filter.

     

 
  • Power 48 V DC.

     

  • Size: 1U (E2000) or 1,5 U (SC).

     

  • 10 GbE ports.

Two-step data processing


netscan / 2-step-data-processing.png

  • Captured PDU’s are streamed transparently into a file to guarantee lossless data acquisition and buffer peaks of traffic.

     

  • PDU’s from recorded streams are processed, correlated into transactions at various levels and indexed. Some low-level statistics are also calculated at this stage. Records and statistics are stored into a local DB while processed PDU’s are kept in indexed files.

Distributed information storage


netscan / distributed-information-storage.png

  • Captured data-streams are processed in real time on local servers.

     

  • Captured PDU’s are correlated at various levels to form DCH transaction, RAN-Core association, NAS transaction, etc.

     

  • Transaction records and statistics are stored in distributed database.

     

  • Users access data in a system through central server and WEB-based application.

User-friendly Interface


netscan / user-friendly-interface.png

 

  • Users access system via easy-to-use, intuitive WEB application.

     

  • No single component needs to be installed on the end-user computer. Just WEB browser.

     

  • Secure access via ciphered connection and domain-based user login (SSO - Single Sign-On).

     

  • User access-rights are controlled by system administrator and allows for geographical and MNO’s data isolation.

     

  • All user activity is securely logged to prevent sensitive data leakage.

Network status indication


netscan / network-status-indication.png

 

  • Network-status screen visualises values of statistics with colours indicating violation of statistics' pre-defined thresholds.

 

  • All elements on screen are active – with a single click one can see statistic details, detailed cell analysis or signalling transactions.

Statistics


 

 

 

 

 

 

  • Multiple statistics in one table.

     

  • Graphical visualisation of many statistics in common geo- and time contexts.

     

  • Graphical visualisation of a single statistic in many geo- and time contexts.

Roaming statistics


netscan / roaming-statistics.png

 

  • Inbound roamers statistics.

     

  • Roaming statistics can be narrowed into region, project or particular BSC/RNC.

     

  • Table can be sorted per each column.

User-terminal statistics


netscan / user-terminal-statistics.png

 

  • Selected statistics are distributed per terminal model and terminal vendor (TAC distribution).

Call tracing


netscan / call-list.png

netscan / call-trace.png

 

Calls can be traced based on:

 

  • localisation (Region->Project-> BSC/RNC->cell),

     

  • terminal or user identity (IMEI, IMSI, TMSI),

     

  • selected transaction parameters (termination cause, type of transaction, etc.),

     

  • specific events – like unsuccessful HO.

Transaction details


netscan / call-radio-parameters-details.png

 

  • Calls can be analysed in tabular and graphical formats.

     

  • Another window conveniently illustrates handover flows.

     

  • Last but not least, a window shows all parameters reported in MR messages and all important RAN events.
    Measurements are correlated with particular cells.

Cell analysis


netscan / cell-analysis.png

 

  • 3-dimensional graphs illustrate correlation between specific measurements reported in MR messages for the selected cell and time.

     

  • Graphs are available for: down-link Rx level vs quality, up-link Rx level vs quality, timing advance vs up-link quality, timing advance vs down-link quality.

Roadmap


  • Support for 2G and 3G RAN interfaces (Iub, Gb).

     

  • eUTRAN monitoring.

     

  • Real-time alarming per cell and/or controller (BSC/RNC). Real-time alarming related to specific subscribers, e.g. VIPs.

     

  • Real-time alarming related to specific subscribers, e.g. VIPs.

     

  • Geo-location.

     

  • Advanced algorithms to support radio-planning (HO relations optimisation, coverage analysis, geo-service analysis).
