Samsung patents base station method to predict phone movement for better handovers
Samsung has been granted a patent for a system where cell towers track a user's movement path and speed to predict where they will go next. By comparing this predicted path with stored models of how phones usually move at that speed, the tower can decide when to switch the connection to a different cell tower before the signal drops.
In the filing’s own words
In a mobility management system and a mobility management method of a base station, position data of a connected target terminal in a cell of the base station is acquired and based thereon a moving track of the terminal is generated and the terminal's speed is determined. Based on a matching degree of the moving track of the terminal with respect to at least one track model corresponding to the speed of the terminal, a track model is selected, for which the matching degree meets a first preset condition from among the at least one track model. An initial matching degree of the moving track of the terminal with respect to the specific track model is obtained; future position data of the terminal is predicted; the initial matching degree is updated; it is determined whether the terminal is to be connected to another base station.
What exactly they claim (claim 1)
1. A mobility management system of a base station, comprising: data acquiring circuitry configured to acquire at a first time interval position data of a connected target terminal in a cell of the base station, and based on the acquired position data, generate a moving track of the target terminal and determine a speed of the target terminal; track model selecting circuitry configured to, based on a matching degree of the moving track of the target terminal with respect to at least one track model corresponding to the speed of the target terminal, select a specific track model of which the matching degree meets a first preset condition from among the at least one track model, and obtain an initial matching degree of the moving track of the target terminal with respect to the specific track model; wherein the data acquiring circuitry is further configured to, after the specific track model is selected, acquire future position data of the target terminal at a second time interval greater than the first time interval; and mobility management circuitry configured to predict future position data of the target terminal based on the specific track model, update the initial matching degree based on a comparison between the predicted future position data and the acquired future position data, and determine whether the target terminal is to be connected to another base station according to the specific track model based on the updated matching degree, wherein the at least one track model is stored by the base station and each of the at least one track model defines a track for a terminal's handover from the base station to a different base station while traveling at the determined speed, and of which an end point is a position at a time of the handover.
