Abstract: The disclosure provides communication methods and apparatuses. One example method including a first access network device sends a first message to a terminal device and a second message to a core network device. The first message is used to indicate the terminal device to enter an inactive state. The second message carries context information and a first security verification parameter of the terminal device, and the first security verification parameter is used to perform security verification on the terminal device. The first access network device receives a third message from a second access network device, where the third message is used to request the context information of the terminal device. The first access network device sends a fourth message to the second access network device, where the fourth message is used to indicate the first access network device not to provide the second access network device with the context information.

Abstract: Embodiments of this application disclose a communication method and a communications apparatus. A source base station instructs a terminal to hand over from the source base station to a target base station, and sends, to the terminal, configuration information of a second connection required for communication between the terminal and the target base station. The terminal maintains a first connection for communication with the source base station, and establishes the second connection for communication with the target base station based on the configuration information of the second connection. The solutions in the embodiments of this application reduces latency in a handover process.
