1. A communication method, comprising:
determining, by a terminal device, that a connection failure occurs between the terminal device and a first cell, wherein the first cell is a cell of a first network device;
in response to determining that a time duration that lapses after the terminal device is successfully handed over to the first network device and before the connection failure occurs is greater than or equal to a predetermined time duration, determining, by the terminal device, signal quality of a second cell of a second network device, wherein both the first network device and the second network device provide communication services for the terminal device; and
in response to determining that the signal quality of the second cell is greater than or equal to a first preset threshold, performing, by the terminal device, a connection recovery process between the terminal device and the first cell by using the second cell.
