An information transmission method and device is provided for preventing, as much as possible, a client from getting an impression that they are being kept waiting for a response, even when the response contains a large amount of data. When a search request is made from a vehicle, an information providing center receives the request (S201), and searches a database to obtain a search result (S202). When the search result contains data of more than one data type such as texts and images, a data group is formed for each data type and the amount of data for each data group is calculated (S205, 206). Transmission order is determined by arranging the data groups in an ascending order of data amount so that the group with the smallest data amount is put first (S207). The transmission order is further determined for each data group by arranging data in an ascending order so that data with the smallest data amount is put first in the group (S209), and data is transmitted to the vehicle in this order (S210). <IMAGE> |
