The invention discloses a cross-domain seamless switching method based on a space-ground integrated network. Belonging to the technical field of satellite communication, the method comprises the following steps: the mobile terminal collects data such as the speed, the position and the signal intensity value of an adjacent base station; the controller predicts the position and the speed of the mobile terminal at the next moment by adopting a Kalman filtering algorithm according to the measurement information and the historical motion information of the mobile terminal, and calculates a receivedsignal strength value of the user terminal at the next moment based on a predicted value; obtaining prediction information according to the prediction information and historical state information ofthe mobile terminal; using Q learning algorithm, the switching decision is associated with the long-term income; a corresponding return function is defined according to the signal intensity value of the candidate base station, the user speed and the switching action, an optimal switching decision is obtained through a Q learning process and sent to the mobile terminal to complete switching, the prediction accuracy is improved, unnecessary switching times are avoided, and the network income in the switching process is improved.
Description
technical field [0001] The present invention relates to the technical field of satellite communication, and more specifically, to a method for seamless handover across domains based on a space-ground integrated network. Background technique [0002] With the high development of aerospace technology and satellite communication technology and the increasingly urgent communication needs of users, the space-ground integrated network formed by the fusion of satellite networks, ground networks and other networks has attracted widespread attention from academia and industry. As an auxiliary communication system, the ground auxiliary base station is widely used in the space-ground integrated network. The communication system based on the ground auxiliary base station effectively combines the advantages of the satellite network and the ground network, and complements each other to meet people's growing communication needs. [0003] Since the satellite communication system has the cha...
