  • Method and system for hub breakout roaming
    Patent number: 9788188
    Abstract: According to at least one example embodiment, hub breakout roaming enables providing data access to a user network device, subscribed with a home network and roaming into a visited network, by a hub breakout system through the visited network. Upon receiving a request for data access from the visited network, the hub breakout system assigns an IP address to the user network device. The hub breakout system then routes data packets, associated with the data access requested by the user network device, to and from at least one corresponding data source, using the assigned IP address. The data source includes the Internet, a private network associated with home network, or any other service provider entity.
