IP flow based offload for subscriber data optimization and scheduling at the basestation in a mobile data network

摘要

Mobile network services are performed at the edge in a flat mobile data network in a way that is transparent to most of the existing equipment in the mobile data network to reduce the load and increase efficiency on the mobile data network by breaking out data at the edge based on specific IP data flows. The mobile data network includes a radio access network and a core network. A first service mechanism in the radio access network breaks out data coming from a basestation based on breakout conditions, and performs one or more mobile network services. The second service mechanism determines what traffic satisfies breakout authorization criteria and informs the first service mechanism. The message from the second service mechanism triggers the first service mechanism to perform IP flow based breakout. An overlay network allows the first and second mechanisms to communicate with each other.

1. A method for processing data packets in a mobile data network that includes a radio access network coupled to a core network, the method comprising the steps of:
a plurality of antennas sending and receiving network messages between user equipment and a plurality of basestations in the radio access network, each basestation communicating with a corresponding one of the plurality of antennas; providing a first service mechanism in the radio access network and a second service mechanism in the core network; establishing breakout authorization criteria on the second service mechanism; the second service mechanism in the core network performs the steps of:
monitoring network messages in the core network to determine traffic that meets the breakout authorization criteria; andsending a message to the first service mechanism with subscriber information for network messages that meet the breakout authorization criteria; the first service mechanism in the radio access network that performs the following two steps for subscriber sessions authorized with subscriber information from the second service mechanism:
applying packet inspection to determine what messages in the radio access network meet breakout conditions; andbreaking out internet protocol (IP) traffic flows that meet the breakout conditions to be serviced by the first service mechanism; and communicating between the first service mechanism and the second service mechanism on an overlay network.
