Communication speed prediction apparatus, communication speed prediction method and recording medium

Abstract

A communication speed prediction apparatus () includes: a position prediction unit () for predicting a future positional relationship between first and second communication apparatuses (B, D); a speed prediction unit () for predicting the future communication speed between the first and second communication apparatuses by using a predicted result by the position prediction unit and a prediction model (PD) for predicting the future communication speed between the first and second communication apparatuses; an extraction unit () for extracting a training information from an information source () including information relating to a past positional relationship between the first and second communication apparatuses and information relating to a past communication speed between the first and second communication apparatuses; a training unit for training a parameter of the prediction model by using the training information; and a model update unit () for updating, by using the trained parameter, the prediction model used by the speed prediction unit, the model update unit changes, based on at least one of a state of the communication speed prediction apparatus and a state of the first and second communication apparatuses, an update frequency by which the prediction model is updated.
