Stable local breakout concept and usage
Abstract
Systems and methods are provided for routing internet protocol (IP) traffic flows when connected to a mobile network and a local network. A wireless transmit and receive unit (WTRU) determines whether to offload an IP traffic flow from the mobile network to the local network based on the destination address of the IP traffic flow. When the destination address is local, the WTRU routes the IP traffic flow through local network. The WTRU determines whether to offload IP traffic to the local network based on the stability state of the local network When the local network connection is sufficiently stable for the application associated with the IP traffic, the IP traffic is offloaded to the local network by selecting the local IP address as the source IP address.
