Zusammenfassung:	PROBLEM TO BE SOLVED: To compensate for the Doppler effect in a communication system in which messages including a pilot signal and a paging channel and an auxiliary pilot signal and an auxiliary paging channel transmitted at a lower data rate than the pilot signal and the paging channel, are transmitted.SOLUTION: A method for deep paging includes: a step of receiving ephemeris messages transmitted from a gateway at a user terminal; a step of storing the ephemeris messages in the user terminal; a step of determining the location of the user terminal; a step of determining Doppler based on the location and the ephemeris messages stored in the user terminal; a step of capturing a pilot signal or an auxiliary pilot signal on the basis of the determined Doppler; and a step of monitoring a paging channel or an auxiliary paging channel on the basis of the captured pilot signal or auxiliary pilot signal.
