Subscriber database for services at the edge of a mobile data network

A mobile data network comprising:

• a plurality of antennas that transmit and receive radio signals to and from user equipment;
• a plurality of basestations, each basestation communicating with a corresponding one of the plurality of antennas, wherein the plurality of basestations are part of a radio access network that communicates with a core network in the mobile data network;
• a service mechanism in the radio access network that defines an existing first data path in the radio access network for non-broken out data, defines a second data path for broken out data, identifies first data received from a corresponding basestation as data to be broken out, sends the first data on the second data path, and forwards other data that is not broken out on the first data path;
• a first subscriber database in the core network used to provide authentication, authorization and accounting services for non-broken out data after authenticating a subscriber, wherein the first subscriber database is generated from information transmitted from a master subscriber database;
• and
• a second subscriber database external to the core network used to provide authentication, authorization and accounting services for broken out data after authenticating the subscriber, wherein the second subscriber database is built one subscriber at a time upon PDP context activation of each subscriber with the mobile data network based on information received from information transmitted from the master subscriber database in response to a signaling event from the core network for a subscriber.
