ABSTRACT:
A data transmission/reception system for offering content download service through a wireless communication network, in which users can obtain desired content on demand from the beginning of content data, and the shortage of line capacity can be alleviated, thus enabling a reduction of communication charges. A mobile terminal is provided with two types of downloading means, an immediate download processing means and a reservation download processing means. The reservation download processing means makes a download reservation by storing the meta-data of desired content. When transmitting content to one mobile terminal that has made a request for an immediate download of the content, a radio base station allocates a prescribed channel for the mobile terminal and sends notification including information on the allocated channel to other mobile terminals in the radio communication zone of the radio base station. Having received the notification, each mobile terminal tunes in to the channel, and selectively download reserved content.
