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 source node 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, wherein the first service mechanism includes a first optimizer and a transmission control protocol (TCP) context for an application that is broken out on the second data path; 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, wherein the second service mechanism includes a second optimizer; 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 makes a breakout decision based on internet protocol (IP) data flows matching breakout conditions to perform the first service on the second data path for subscriber sessions with subscriber information from the second service mechanism; and wherein the first optimizer and the second optimizer coordinate to transfer the TCP context to the second optimizer to shift the end point for the TCP communication to the second service mechanism in response to detecting a mobility event of a user equipment (UE) moving from the source node to a target node to allow the second optimizer to serve the UE after the mobility event.
