Claim 16:
17. The timing advance update method according to claim 14, wherein performing, by the terminal, TA compensation based on the updated TA value and the TA compensation information comprises:
when a distance between the terminal and the satellite is less than or equal to a first communication distance, adding, by the terminal, the updated TA value and an absolute value of the maximum TA offset to perform TA compensation; or
when the distance between the terminal and the satellite is greater than or equal to a second communication distance, subtracting, by the terminal, an absolute value of the minimum transmission delay TA offset from the updated TA value to perform TA compensation, wherein the second communication distance is greater than the first communication distance.
