Patent ID: 7447486

Claim:
A data transmission/reception system, comprising: a radio base station; a plurality of mobile terminals; and a content server for managing contents; wherein: the mobile terminals each include an immediate download processing means for immediately downloading desired content from the content server, said content being on-demand content for delivery starting from a beginning of the content, and reservation download processing means for reserving a download of content to download the content afterwards; the reservation download processing means reserves a download of desired content by obtaining and storing meta-data of the content; the radio base station assigns a downlink shared channel to the mobile terminal which immediately downloads content by the immediate download processing means when transmitting the content thereto, and simultaneously notifies all the mobile terminals in the radio communication zone of the radio base station about information on the downlink shared channel and meta-data of the outgoing content; and the mobile terminals that have been notified of the information match the notified meta-data with the meta-data stored by the reservation download processing means, and tune in to the downlink shared channel to download the content when the outgoing content proves coincident with the reserved content.
