Abstract:
1. A mobile data network comprising: a plurality of basestations, each basestation communicating with a corresponding antenna that transmits and receives radio signals to and from user equipment, wherein the plurality of basestations are part of a radio access network that communicates with a core network in the mobile data network; a first service mechanism associated with a basestation of the plurality of basestations 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, wherein the first service mechanism performs a first service for network messages in the radio access network based on the first data; a second service mechanism in the core network that monitors network messages in the core network and determines what traffic meets breakout authorization criteria and sends a message to the first service mechanism with subscriber information for the first service mechanism to perform breakout sessions on the second data path; an overlay network that allows the first service mechanism to communicate with the second service mechanism to perform the first service; wherein the first service mechanism snoops an interface to fetch and store subscriber session identifiers and the second service mechanism provides to the first mechanism subscriber identification (ID) data and tunnel identifiers; and wherein the first service mechanism uses the provided subscriber ID data and tunnel identifiers to identify tunnel endpoints to support breakout and optimization at the first service mechanism.
