Satellite internet user terminal short-term service volume demand prediction method and device

Abstract

The invention provides a short-term service volume demand prediction method and device for a satellite internet user terminal. The method comprises the following steps: training a deep recurrent neural network model with a flexible characteristic by using historical service volume data of a satellite internet user; during training, randomly generating a plurality of sets of network parameter value combination schemes, training the plurality of sets of network parameter value combination schemes by using a training sample set, evaluating a training result, and selecting an optimal network parameter value combination scheme; obtaining current service data, inputting the current service data into the network model, and outputting a user terminal short-term service volume demand prediction value. According to the method, the deep recurrent neural network model with the flexible characteristic is used, which model is selected to be optimal according to prediction result evaluation, which model is bound into a trained network structure for prediction, training and prediction are not limited to one model, the optimization space of the deep recurrent network for solving the prediction problem is effectively expanded, and the prediction precision is improved.

Description

technical field [0001] The invention belongs to the technical field of satellite Internet resource management, and in particular relates to a method and device for predicting short-term traffic demand of satellite Internet user terminals. Background technique [0002] Satellite Internet can provide global users with high-speed, wireless broadband access and multi-type communication services, and solve the communication and interconnection needs of users who lack ground network coverage. Compared with terrestrial optical fiber, satellite Internet is used for interactive communication between ultra-long-distance users with a smaller delay. The satellite Internet system is mainly composed of the space segment, the ground segment and the user segment. The space segment is a constellation of communication satellites with global coverage; the ground segment includes the operation management center and several gateway stations distributed around the world; the user segment include...
