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 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, the first service mechanism including a first radio channel handler that injects a first plurality of channel maintenance data packets into an uplink data stream in the radio access network on a network tunnel; a second service mechanism in the core network that monitors network messages in the core network and performs a second service for the network messages in the mobile data network, the second service mechanism including a second radio channel handler that injects a second plurality of channel maintenance data packets into a downlink data stream in the core network on the network tunnel; and an edge cache mechanism in the radio access network that indicates when a cache miss occurs, and in response, receives data corresponding to the cache miss on the network tunnel without regard to a need for channel maintenance data packets.
