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 channel assignment and speed monitoring mechanism in the core network that performs channel assignment and assigns a selected channel in the radio access network to be a high-speed channel, and that monitors traffic on the selected channel, and when the channel assignment and speed monitoring mechanism detects a data rate on the selected channel below a defined threshold, the channel assignment and speed monitoring mechanism switches channel type of the selected channel from high-speed to low-speed; 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 so the channel assignment and speed monitoring mechanism does not switch the selected channel from high-speed to low-speed; and 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 so the channel assignment and speed monitoring mechanism does not switch the selected channel from high-speed to low-speed.
