Abstract
Example wireless communication methods and apparatus are described. One example method includes a terminal initiates a reestablishment procedure when a handover procedure of the terminal fails. When a base station reselected by the terminal is a base station (that is, a target base station) to which the terminal is handed over in a handover procedure, and because a key of the base station is updated in the handover procedure, the base station includes key derivation information in a reestablishment message to be sent to the terminal. Therefore, the terminal can update a key of the terminal based on the key derivation information, so that the key of the terminal can be consistent with the key of the base station.
