Abstract: The method includes determining a first type of a target network device for a first handover, the first type indicating whether a network device is a master network device or a secondary network device; transmitting a first message indicating the first type of the target network device for the first handover, so that the terminal device is disconnected with the first type of a source network device; and in response to the terminal device being connected with the first type of the target network device, a second message indicating that the first handover is completed, and the terminal device being connected with a second type of a target network device and disconnected with the second type of a source network device in a second handover, the second type being different from the first type and indicating whether a network device is a master network device or a secondary network device.
