Abstract
Various arrangements are presented for optimizing data transmission between a satellite and a user equipment. A satellite gateway system may receive a message from the user equipment indicative of a current location of the user equipment. Data may be retrieved from the Internet to be transmitted to the user equipment via the satellite. The satellite gateway system may transmit a downlink message to the satellite that comprises the retrieved data and beam steering data. The beam steering data may instruct the satellite to target a downlink spot beam on the current location of the user equipment based on the message received from the user equipment. The retrieved data may be transmitted to the user equipment via the targeted downlink spot beam.

A method for optimizing data transmission between a satellite and a user equipment, the method comprising:
- receiving, by a satellite gateway system, a message, from the user equipment indicative of a current location of the user equipment;
- retrieving, by the satellite gateway system, data from the Internet to be transmitted to the user equipment via the satellite;
- transmitting, by the satellite gateway system, a downlink message to the satellite that comprises the retrieved data and beam steering data, wherein the beam steering data instructs the satellite to target a downlink spot beam on the current location of the user equipment based on the message received from the user equipment, such that the retrieved data is transmitted to the user equipment via the targeted downlink spot beam;
- storing, by the satellite, a lookup table that maps a plurality of spot beam identifiers to a corresponding plurality of spot beam target locations, wherein the beam steering data comprises a spot beam identifier;
- performing, by the satellite, a lookup in the lookup table based on the beam steering data;
- and
- performing, by the satellite, a beam-forming process based on the lookup to target the downlink spot beam to the user equipment based on the lookup.
