Satellite terminal and communication link transition method performed by the same

摘要

A method of performing a communication link transition performed by a satellite terminal is provided. The method includes scanning a gap filler link signal during satellite broadcasting and communication through a satellite link, receiving the gap filler link signal as a result of the scanning, determining whether or not the received gap filler link signal satisfies requirements, and performing a communication transition from a satellite link to a gap filler link when the requirements are determined to be satisfied. Accordingly, bi-directional satellite broadcasting and communication services can be provided in a shadow region, such as a tunnel, without interruption.
