Abstract
A communication method includes: sending, by a first device, a handover request message to a second device, and receiving a handover acknowledgement message returned by the second device, where the handover acknowledgement message carries common system information of the second device; sending, by the first device, a handover command to a terminal, where the handover command includes the common system information of the second device; sending, by the first device, a second message to the terminal based on a first message, so that the terminal obtains changed communications system information of the second device based on the second message, where the first message is sent by the second device, and the first message is used to indicate a change occurring in the common system information of the second device.
