Abstract
A method and system supports subscriber based IP data breakout at the edge of a mobile data network without monitoring the use of security keys or breaking into ciphered message exchanges. The system employs a first service mechanism operating at the edge of the mobile data network a second service mechanism operating at the core on the S11 interface. The second service mechanism at the core collects subscriber related data, subscriber identifiers and tunnel identifiers and sends this data to the first service mechanism. The second service mechanism at the core collects subscriber related data, subscriber identifiers and tunnel identifiers and sends this data to the first service mechanism. The first service mechanism uses the tunnel identifiers received from the second service mechanism to identify sessions and tunnels carrying subscriber dependent data packets (S1-U packets) in order to perform subscriber-based IP data breakout, offloading and optimization.
