The method is performed by a target base station and includes: receiving a handover request from a source base station, where the handover request includes a first key and first indication information, and the first indication information is used to indicate whether the first key is an updated key; and sending second indication information to the source base station based on the handover request, where the second indication information is used to indicate whether an access layer key between the target base station and a terminal device is an updated key. Using the embodiments of the present disclosure helps resolve a problem that a potential security risk exists in data transmitted between the terminal device and the target base station, and helps resolve a problem that a key change of the terminal device is not controlled by the base station."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication method and device","description":"The present disclosure discloses a communication method and a device.
