An information sending method, a key generation method, and an apparatus, where a core network element first determines whether a terminal device needs to perform a key activation procedure, and then sends a first message to an access network element, where the first message indicates whether the access network element needs to send, to the terminal device, a second message to trigger the terminal device to perform the key activation procedure. After receiving the first message, the access network element determines, based on the first message, whether the second message needs to be sent to the terminal device, and sends the second message to the terminal device when the second message needs to be sent to the terminal device.
