Abstract

A flow setup table in a basestation breakout component allows for servicing non-cacheable IP data flows at the breakout component without the need for network address translation. For each broken out IP flow at the breakout component, the flow setup table holds a mapping between tunnel IDs and the IP related information. The flow setup table data is sent to the breakout component at the gateway. The gateway breakout component uses the flow setup table to forward non-cacheable data requests to the internet and return data received from the internet back to the basestation breakout component. The basestation component then sends the non-cacheable data in the correct tunnel to the user equipment requesting the data.

First claim

The invention claimed is:

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 net…
