<p>PROBLEM TO BE SOLVED: To obtain a data distribution system that distributes data in a way that when a user of a wireless terminal moves to a destination, the wireless terminal receives data utilized at its destination just before the destination to the utmost and uses the data. SOLUTION: When a user 102 of a mobile phone 101 goes to a destination by train, the user 102 stores data distribution schedule information to a distribution center 105 via a base station 111. The distribution center 105 calculates data with respect to a time when the user 102 reaches the destination on the basis of a mobile schedule to the destination and stores the data to a data distribution schedule information storage section 116. The data distribution schedule information storage section 116 eliminates the error time of earlier arrival and generates data distribution schedule information. A data transmission section 113 sets a difference between a current time and the distribution schedule time to a timer circuit 119 and transmits the distribution data stored in a distribution data storage section 118 to the mobile phone 101 when the time comes round. Even when the destination changes attended with the movement of the user 102, since the data required at the destination near the destination are distributed, the memory can efficiently be utilized.</p> |
