Abstract
In a time deviation determining method, a terminal determines an uplink timing advance between the terminal and a base station; determines a one-way transmission delay based on the uplink timing advance; and determines a clock time deviation between the terminal and the base station based on the one-way transmission delay, a time difference between a base-station clock time of a system frame in two system frames and a terminal clock time of a following system frame in the two system frames, and a time difference between the two system frames. In the solution provided in this application, the clock deviation between the terminal and the base station can be determined more flexibly and accurately. In addition, signaling interaction between the terminal and the base station is reduced, and network resources are saved.
