Mobility across satellite beams using L2 connectivity
First Claim
1. A method of satellite communication, the method comprising:
- providing a communication service for an aircraft by a first gateway servicing a first spot beam having a first spot beam coverage area that includes a location of the aircraft;
assigning, to a device on the aircraft, an Internet Protocol (IP) address;
communicating, via the first gateway servicing the first spot beam, first session traffic according to the IP address, the first session traffic associated with an application executing on the device;
identifying an imminent transition of the aircraft from being provided the communication service via the first spot beam to being provided the communication service via a second spot beam that is serviced by a second gateway;
sending, from the first gateway to the second gateway, a handoff message for handoff of the IP address for the device from the first gateway to the second gateway; and
communicating, upon the transition of the aircraft to being provided the communication service via the second spot beam serviced by the second gateway, second session traffic associated with the application via the second gateway servicing the second spot beam, the second session traffic being communicated according to the IP address.

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.

10. A system for providing mobility across satellite beams, the system comprising:
-
a first gateway servicing a first spot beam having a first spot beam coverage area, the first gateway providing a communication service for an aircraft at a location within the first spot beam coverage area, the first gateway communicating first session traffic according to an IP address assigned to a device on the aircraft, the first session traffic associated with an application executing on the device; and a second gateway servicing a second spot beam, wherein the first gateway identifies an imminent transition of the aircraft from being provided the communication service via the first spot beam to being provided the communication service via the second spot beam and sends a handoff message to the second gateway for handoff of the IP address for the device from the first gateway to the second gateway, and wherein the second gateway communicates, upon the transition of the aircraft to being provided the communication service via the second spot beam serviced by the second gateway, second session traffic associated with the application, the second session traffic being communicated according to the IP address. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
