Abstract: Example communication methods apparatus are described. One example method includes receiving air interface link signal information of neighboring network devices by a source network device from a terminal device. The source network device determines a target network device based on sidelink information of the terminal device and the air interface link signal information of the neighboring network devices. Then, the source network device may send a handover request to the target network device, so that the terminal device can be handed over from the source network device to the target network device. Therefore, the target network device determined by the source network device can better meet an air interface link communication requirement and a sidelink communication requirement of the terminal device.
