SYSTEM AND METHOD FOR PROVIDING SATELLITE GTP ACCELERATION FOR SECURE CELLULAR BACKHAUL OVER SATELLITE
20190207747 · 2019-07-04 ·

A method and system for providing GTP acceleration for secure cellular backhaul over satellite (CBoS). A satellite terminal receives request from a first entity to establish a security association with a second entity, and establishes a first secure tunnel to a gateway. A second secure tunnel is then established between the gateway and the second entity based on a certificate belonging to the first entity. A third secure tunnel is established between the satellite terminal and the first entity based on a certificate belonging to the second entity. The contents of encrypted traffic between the first entity and the second entity are examined so that GTP acceleration may be applied to eligible traffic transmitted over the first secure tunnel.

VSAT DEMODULATOR ARCHITECTURE FOR BEAM HOPPING SATELLITE SYSTEMS
20240195556 · 2024-06-13 ·

Techniques are described for demodulating burst communications, such as for demodulating satellite beam-hopping communications in a demodulator of a very small aperture terminal (VSAT) satellite receiver. The demodulator includes a front-end and a sample/symbol domain processor. The front-end is configured to selectively operate in either of an adaptive mode or a freeze mode. During demodulation, the sample/symbol domain processor detects start of superframe (SOSF) and end of superframe (EOSF) locations to determine where each dwell time and non-dwell time begins and ends. During at least a portion or each dwell time, the front-end is set to operate in adaptive mode, in which the front-end uses feedback control from the sample/symbol domain processor to continuously adapt to timing and frequency of the received burst transmission. During at least the duration of each non-dwell time, the front-end is set to operate in freeze mode, in which adaptation of the front-end is frozen.
