Path predicting method for contents delivery apparatus
First Claim
1. A path predicting method for a contents delivery apparatus for temporarily storing contents which is preliminarily reserved into a contents storage and delivering the contents from one of a plurality of radio base station to a mobile terminal of which geometric position changes, comprising:
- a first step of calculating a plurality of paths each extending from a start point as a present location to a finish point as a destination via one of the radio base stations;
a second step of selecting a radio base station from one of the radio base stations which;
is on the calculated path and is determined as a contents delivery base station;
a third step of calculating grace time for the mobile terminal to pass through the contents delivery base station and calculating scheduled time to deliver the reserved contents to the mobile terminal based on the calculated grace time; and
a fourth step of determining whether the mobile terminal is off the path to the contents delivery base station or not,wherein the first to third steps are executed recursively in accordance with the determination that the mobile terminal is off the path in the fourth step, otherwise, the contents are delivered to the mobile terminal via the contents delivery base station in accordance with results obtained in the second and third steps.

Abstract
The present invention is directed to improve convenience to the user. A path extending from the present location S of a mobile terminal to a destination D via a base station is calculated (S2), distances between base stations on the calculated path and the present location are calculated, and the closest base station is determined as a contents delivery base station (S7). Grace time for the mobile terminal to pass through the contents delivery base station is calculated. Then, scheduled time to deliver the contents to the mobile terminal is calculated (S8). While monitoring a travel state of the mobile terminal (S10 to S12), the contents are delivered to the mobile terminal near the contents delivery base station (S14).
