Abstract
The present invention provides a method for intercepting and monitoring of cellular satellite communication wherein communication between at least one mobile device (MES) and the satellite is through a first band link that includes plurality of first-band spot beams each accommodating at least one basic channel unit that includes a control channel and corresponding traffic channels, and communication between the satellite and main station is through wideband second-band link accommodating plurality of second band spot beams each accommodating at least one basic channel unit that includes a control channel and corresponding traffic channels, the method comprising detecting map between a control channel of the downlink first band link and corresponding control channel of downlink second band link by identifying identical unique spot beam number (SB Mask) data in the respective control channels.
