A network node can receive remote downlink traffic from a remote network, receive local downlink traffic from a local resource, aggregate at least the remote downlink traffic with the local downlink traffic based on one or more filters stored in memory of the network node, and route the aggregated downlink traffic to a wireless communication device. The remote downlink traffic can be associated with a first application of the wireless communication device, and the local downlink traffic can be associated with a second application of the wireless communication device. The network node can be a local gateway in certain embodiments. The network node can steer uplink traffic steering by filtering uplink traffic associated with the wireless communication device into local uplink traffic and remote uplink traffic based on at least one filter for filtering traffic stored in the memory. ## Claims ### Claim 1 A network node with local breakout, the network node comprising: a memory configured to store one or more filters for aggregating traffic;
