Abstract

Systems and methods for providing mobility across satellite beams, are described. The system includes a first core node, a second core node in communication with the first core node at layer-2 of the OSI model (L2), and a first gateway in communication, at L2, with the first core, the first gateway configured to provide access to a first spot beam at a first location. The system further includes a second gateway in communication, at L2, with the second core node, the second gateway configure to provide access to a second spot beam at a second location, and a mobile device, at the first location, in communication with the first gateway via the first spot beam, wherein the mobile device is assigned an IP address by the first core node. The mobile device moves from the first location to the second location. Further, the first gateway, in response to the mobile device moving from the first location to the second location, notifies the second gateway, through the first core node and the second core node, that the mobile device is moving to the second location, and transmit the session information to the second gateway, and the second gateway, in response to the notification, maintains connectivity with the mobile device using the IP address.
