Abstract

The embodiment of the present invention discloses a method and device for predicting a destination based on a location trajectory. After the method detects that the location of the target user has changed, it starts to predict the destination that the target user will arrive at based on the real-time location of the target user. predict. During the prediction process, different prediction algorithms are selected according to the number of target location signaling corresponding to the target user. When the number of target location signaling is not sufficient, the destination of the target user is predicted with reference to the public location signaling, avoiding the Inaccurate predictions due to insufficient target position signaling. On the other hand, compared with the method of predicting the user's destination using a unified prediction method, this method simplifies the calculation process of prediction, and this method can predict the destination that the user will arrive at according to the user's real-time location. The timeliness of forecasting is fully considered.

Description

technical field [0001] The present invention relates to the technical field of mobile communication positioning, in particular to a method and device for predicting a destination based on a position track. Background technique [0002] The destination forecast based on the user's location trajectory is mainly used to predict the destination that the user may go to in the future based on the user's current action trajectory, which can help us prepare in advance before the user arrives at the destination, so as to reasonably It can also be used in public fields such as passenger flow warning. [0003] The current methods of historical trajectory destination prediction include the destination prediction model based on traditional statistical analysis, which is calculated based on conditional probability. The Destination Prediction Model of Statistical Statistics overcomes some weaknesses of traditional statistical analysis, but at the same time it also faces the problem of sta...
