The network resource reservation method based on the terminal moving speed, the network resource reservation device, and the network resource reservation system, and the mobile terminal to be used in this

摘要

PROBLEM TO BE SOLVED: To provide method, device and system, and mobile terminal used in the latter, which is intended to estimate the expected moving direction of a terminal so as to minimize the reservation of unnecessary network resources.;SOLUTION: The method includes a step of receiving a reservation request for a network resource from a mobile terminal; a step of calculating an expected moving direction of the mobile terminal, based on a probability model of movement, based on a speed represented by a probability density function for a direction of travel possibility, relying on a moving speed of the mobile terminal, a moving speed of the mobile terminal, and positional information of the mobile terminal; and a step of making reservation of a network resource for a wireless cell involved in the expected moving direction calculated in the previous step.;COPYRIGHT: (C)2009,JPO&INPIT
