Mobility across satellite beams using L2 connectivity
First Claim
1. A system for providing mobility across satellite beams, the system comprising:
- a first core node configured for processing at multiple layers of the OSI-model;
a second core node in communication with the first core node at layer-2 of the OSI model (L2);
a first gateway in communication, at L2, with the first core node, the first gateway configured to provide access to a first spot beam at a first location;
a second gateway in communication, at L2, with the second core node, the second gateway configured to provide access to a second spot beam at a second location;
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, and wherein the mobile device moves from the first location to the second location;
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 transmits 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.

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 transmits 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.

6. A method of providing mobility across satellite beams, the system comprising:
-
providing access to a first spot beam at a first location serviced by a first gateway; providing access to a second spot beam at a second location serviced by a second gateway; assigning a mobile device, at the first location, an IP address by the first gateway, wherein the mobile device moves from the first location to the second location; in response to the mobile device moving from the first location to the second location, notifying the second gateway, through a first core node and a second core node, that the mobile device is moving to the second location, the first and second core nodes configured for processing at multiple layers of the OSI-model; transmitting the session information to the second gateway; and in response to the notification, maintaining by the second gateway connectivity with the mobile device using the IP address. - View Dependent Claims (7, 8, 9, 10)

11. A non-transitory computer-readable medium having sets of instructions stored thereon which, when executed by one or more computers, causes the one or more computers to:
-
assign a mobile device, at a first location serviced by a first gateway with a first spot beam, an IP address by the first gateway, wherein the mobile device moves from the first location to a second location serviced by a second gateway with a second spot beam; in response to the mobile device moving from the first location to the second location, notify the second gateway, through a first core node and a second core node, that the mobile device is moving to the second location; and transmit the session information to the second gateway for maintaining connectivity with the mobile device using the IP address. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
