Abstract: A method includes: adjusting, by a base station based on a timing adjustment amount, an access timing advance corresponding to user equipment to obtain a target timing advance, where the access timing advance is a timing advance obtained when the user equipment randomly accesses the base station; determining, by the base station based on the target timing advance, whether the user equipment meets a trigger condition; and if the user equipment meets the trigger condition, sending, by the base station, a trigger signal to the user equipment, where the trigger signal is used to trigger the user equipment to send a first random access request to the base station.
