Patent ID: 7421396

Claim:
A travel information distribution method comprising: preparing a schedule table containing destinations as reference places for obtaining travel information, position information of the destinations and distribution data to be distributed to a wireless terminal of a user when the user is located in any of the reference places, from an itinerary table of a travel; detecting position information as a present place of the wireless terminal carried in the travel; storing, in a tolerance table, tolerances between position information of reference positions of respective destinations and position information of border positions of respective destinations included in the schedule table prepared by the preparing step; calculating, by an area calculator, areas of respective destinations from the position information of the reference positions of respective destinations and the tolerances included in the tolerance table; comparing the areas calculated by the area calculator with the position information of the wireless terminal detected by the detecting step; distributing, by a data distributor, distribution data related to the destination area including the position information of the wireless terminal to the wireless terminal via a network when the position information of the wireless terminal is included in any destination area as determined by the comparing step; storing, by the wireless terminal, identifying information for identifying the distribution data distributed by the data distributor; specifying, by the wireless terminal one of a presence and an absence of use of the distribution data related to the identifying information stored in the distribution data identifying information storage; notifying, by the wireless terminal, the data distributor of the distribution data specified by the specifying step after finishing of the travel; and renewing, by the data distributor, the tolerances stored in the tolerance table based on information corresponding to the distribution data specified by the specifying step after finishing of the travel, wherein the specifying step comprises detecting the user operating an input device provided on the wireless terminal, in which operation of the input device by the user when the distribution data is provided on a display of the wireless terminal signifies the presence of use of the distribution data, and non-operation of the input device by the user when the distribution data is provided on the display of the wireless terminal signifies the absence of use of the distribution data.
