A satellite switching method and device, a storage medium and a chip system, relate to the field of communication technology, and are used for reducing signaling overhead and delay in a switching process of a first terminal device. In the present application, a first communication device sends a first request message to other devices in a case where it is estimated that the first terminal device will switch from a source access network device to a first target access network device at a future time. The first request message indicates that a PDU session of the first terminal device is estimated to switch at the future time, or the first request message indicates that the first terminal device is estimated to switch at the future time. In this way, other devices can prepare for the switching of the first terminal device in advance, thereby reducing the signaling overhead in the switching process of the first terminal device, and thus reducing the delay in the switching process of the first terminal device.
