Content Intercept Manager Platform
Content Intercept Manager consists of:
Metadata/Voice Acquisition Platform
Probes extract data from the appropriate cellular network interfaces.
The probes are able to automatically discover all required network
data and run IMSI/TMSI mapping so that the system can constantly
track and update the allocation of a TMSI for a particular IMSI within
a cellular network.
The probe then needs to discover the relationship between the path
ID in the signaling and the channels carrying the AMR encoded voice
in order to capture and reconstruct both sides of the conversation.
Probes are remotely accessible and controllable, allowing extended
operation and data forwarding to the Media Server or an external
storage and analysis platform. The data format is compatible with
legacy database systems and can be readily integrated with many
existing solutions.
Media Server System
The Media Server System handles the storage of user and control
plane files for user-defined targets.
As soon as a user creates a new target, the Media Server immediately
requests the probe to capture the call or SMS from the network
links. It records this data and updates the status and details of all
monitored calls in real time, correlating call data from multiple probes
if necessary. It consolidates all the information associated with a call
into a single call record, converting the data into a format that is easy
to understand and use:
– Voice is extracted and converted to 2-channel .WAV files (one
channel for each direction). Active voice calls can be played live
on the user interface
– SMS data is extracted and decoded for user viewing
– In band DTMF tone analysis and decoding on voice calls is
provided
– Supplementary services (call forwarding, call waiting, three way
calling etc) are identified, captured and dispayed
– User data capture for PCAP decoding
The user interface displays the current call status for all calls match-
ing filtered POIs.
Up to ten users can connect to the Media Server System simulta-
neously. Besides examining calls matching monitored POI filters in
real time, they can easily retrieve and view the history of all calls of
interest. Defining new tagets or editing existing is fast and easy.
