The only frequencies the MES initially knows are the frequencies of the NCSC in all regions - all other fre-
quency information is dynamically extracted from the NCS Bulletin Board or in session oriented signaling
messages. After being switched on, the MES must be told (or remembers) in which region it is currently
located, and will automatically tune to the corresponding frequency of the NCS. The terminal will then
search through the NCSS spot beam ID frequencies to identify the best spot beam.
