Abstract: A path switching method includes: determining, by a base station, to switch a first terminal device from a first communication link to a second communication link, and sending, to the first terminal device by using a second terminal device, access information required by the first terminal device to access the base station, so that the first terminal device establishes the second communication link to the base station based on the access information. In the method, the second terminal device may release the first communication link before or after the second communication link is established, or may release the first communication link in a process of establishing the second communication link.
