Data distribution system
First Claim
1. A data distribution system comprising:
- a mobile information table for storing reference required time periods which are references of required time periods required when a radio terminal moves to a destination that is a place of a destination of movement from departure places which are origins of the movement, respectively, and that is a place where utilization of information distributed in advance is conducted by means of the radio terminal, in accordance with mobile means which is used for movement;
movement specifying means for specifying departure places and destinations stored in the mobile information table in accordance with a movement schedule together with starting date and hour of the movement and the mobile means;
error calculating means for calculating an error in time for date and hour which is a reference when the radio terminal arrives at the respective destinations, based on information specified by the movement specifying means;
data distribution plan information generating means for obtaining date and hour when the radio terminal arrives at a destination from the respective departure places using the mobile means specified by said movement specifying means by correcting an error calculated by the error calculating means from the date and hour in case of using the reference required time periods, as date and hour when it arrives at the destination most quickly within a range of the error;
arrival time point detecting means for comparing arrival date and hour corrected for each destination, which is generated by the data distribution plan information generating means, with current date and hour, and detecting a time point when said radio terminal arrives at the respective destinations;
distribution data storing means for storing a data to be distributed to said radio terminal for every destination;
distribution data distributing means for distributing distribution data corresponding to a destination from the distribution data storing means every time said arrival time point detecting means detects arrival of said radio terminal at the respective destinations; and
an overwrite means for overwriting the distribution data distributed when the radio terminal arrived at a previous destination by the distribution data distributed when the radio terminal arrived at the new destination.

Abstract
When going to a destination, a user of a mobile telephone set stores data distribution plan information in a distribution center via a base station. In the distribution center, an error data for arrival time at the destination is calculated, and is stored in a data distribution plan information storage section. The data distribution plan information storage section subtracts an error time period, after which arrival will be earlier, and generates data distribution plan information. A data transmitting section sets a difference between the current time and distribution scheduled time in a timer circuit, and when time has come, transmits a distribution data stored in a distribution data storage section to the mobile type telephone set.
