Abstract

The embodiment of the invention provides an NTN-TN switching method and device, equipment and a readable storage medium. The method comprises the steps that a terminal obtains service information of the next moment; the terminal judges whether switching between the NTN and the TN needs to be carried out or not according to the obtained service information at the next moment; and if the switching between the NTN and the TN needs to be carried out, the terminal sends a first message to a source base station, and the first message is used for requesting the switching between the NTN and the TN. In the embodiment of the invention, the switching process is no longer triggered only by the traditional RSRP or RSRQ measurement, and the NTN-TN switching is actively requested to the source base station through the service information of the next moment acquired by the terminal from the application layer; the source base station selects a target base station most suitable for switching for the terminal by comprehensively considering factors such as the moving speed and the moving direction of the terminal and the load condition, the moving speed and the moving direction of the candidate target base station, so that the service continuity of the switching process between the non-ground network and the ground network is ensured.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communication, and specifically relate to a non-terrestrial network (Non-Terrestrial Networks, NTN)-terrestrial Networks (Terrestrial Networks, TN) handover method, device, device, and readable storage medium. Background technique [0002] see figure 1 , showing a typical scenario of intercommunication between a non-terrestrial network and a terrestrial network. In traditional handover, the source base station makes a judgment on whether the terminal needs to perform handover according to the ratio of the measurement report result of the terminal to the measurement threshold. The measurement mainly includes Reference Signal Received Power (RSRP) / Reference Signal Received Quality (Reference Signal Receiving Quality). , RSRQ), and for the handover between the non-terrestrial network and the terrestrial network, it may no longer be applicable to judge whether to handover based so...
