Using the maintenance channel in a mobile data network to provide subscriber data when a cache miss occurs

摘要

A 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. When data is broken out by the first service mechanism, the data is delivered at the edge, which means the true activity of the channel is not visible to the core network. In order to maintain the high-speed channel, channel maintenance data packets are sent to and from the radio network controller on the network tunnel. The maintenance channel is also used to send cache miss data to a subscriber when a cache miss occurs at the edge of the mobile data network, without regard to a need for channel maintenance data packets.

主权项

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) providing a first service mechanism in the radio access network that performs the step of:
injecting a first plurality of channel maintenance data packets into an uplink data stream in the radio access network on a network tunnel; (B) providing a second service mechanism in the core network that performs the steps of:
injecting a second plurality of channel maintenance data packets into a downlink data stream in the core network on the network tunnel; (C) providing an edge cache mechanism that performs the steps of:
indicating when a cache miss occurs; andin response to the cache miss, receiving data corresponding to the cache miss on the network tunnel without regard to a need for channel maintenance data packets.
