CDMA Interception Logging System,Cellular Network Monitoring, Multiple CDMA Base Station surveillance

CDMA Monitoring System - CMS is intended to ensure interception of voice conversation and service information in CDMA (IS-95A, IS-95B, CDMA 2000-1x) cellular network.

To prevent detection of the System's operation and avoid interference to the operation of cellular network the System works as a passive equipment intercepting data directly from the air.

The System is able to monitor multiple base stations simultaneously working at the same frequency with different Pilot-PN. The System is able to ensure the following functions:

Automatically search for used CDMA cellular network frequency

and logic channels.

Evaluate base station signal quality and level.

Fix and record information sent in service channels.

Record and playback audio information (messages).

Determine call direction (from base station to mobile phone or

backward).

Determine subscriber's real phone number or ESN during his

registration in the network and call.

Determine real calling phone number (if mobile phone

subscriber has Caller ID function).

Monitor and record incoming SMS.

Determine time of the beginning of conversation.

Determine duration of conversation.

Ensure search of target subscriber according to air number.

Data Storage and Archive Processing All data received by the System (audio information and corresponding service data stream) can be recorded at the control PC HDD. To ensure review, assortment and long-term storage of information an auxiliary PC may be used. To do this, there is a special program CView that ensures convenient review of all service information concerning voice conversations (direction of call initiation (mobile phone or base station), time of the beginning of conversation, its duration, etc.) and playback of audio files.

Both the System and auxiliary PC ensure quick access to the information been recorded.
