CommWorks Wednesday announced that its 3G wireless data networking products now support federally mandated security specifications.
The specifications, called the Communications Assistance for Law Enforcement Act (CALEA) of 1994, require wireless and wireline telephone carriers to ensure monitoring capabilities for law enforcement authorities on all types of communications mediums.
CommWorks integrated this feature into its Total Control 1000 Packet Data Serving Node (PDSN), which acts as the subscriber's point of entry into the wireless packet data network. The feature can also be found in the company's Total Control 1000 Home Agent and the CommWorks 4301 Home Agent Control Node. The Home Agent terminates Mobile IP tunnels and the Home Agent Control Node manages multiple agents.
CALEA support allows the Home Agent and Home Agent Control Nodes to identify when calls made by targeted persons are initiated. Once identified, the PDSN is activated to duplicate every packet from that user and forward them to a secured destination, where they are subsequently delivered to the monitoring law enforcement agency.
The CommWorks 4302 Foreign Agent Control Node also supports the CALEA requirement. It manages multiple PDSNs in a Code Division Multiple Access (CDMA) 2000 1xRTT network.
CommWorks points out that the surveillance functionality will not be turned on for all wireless data users. It is used solely for those wireless users suspected of illegal behavior and can only be used after law enforcement agents obtain the pertinent court orders to initiate surveillance.
Once the court orders are obtained, the target users are put into a database used by the PDSN.
The company announced the availability of CALEA support in its products for 2G CDMA2000 wireless networks last October.
