Abstract
Lawful interception (LI) is supported on a flat mobile data network with breakout services at the basestation. A first service mechanism at the basestation is prevented from breaking out services for subscribers that are part of LI. A second service mechanism in the core network maintains a subscriber list of subscribers that are subject to LI. In response to a PDP context activation by a subscriber on the list, the second service mechanism does not supply PDP context information to the first service mechanism for data breakout thus preventing breakout for the subscriber subject to lawful interception.
