Abstract
An embodiment of this application provides a communications method. The method includes: generating, by an first base station, a radio resource control release message on which encryption and integrity protection are performed by using a new key; and sending, by the first base station, the radio resource control release message to a second base station, thereby improving security of communication between the serving device and the terminal and reducing signaling overheads for performing key negotiation over an air interface.
