1. A radio access system comprising:
a controlling apparatus configured to
receive position information transmitted from terminal apparatuses,store the received position information,obtain, from among the stored position information, position information of destination terminal apparatuses to which delivery data is to be delivered,when the destination terminal apparatuses are judged to be concentrated in a particular area in accordance with the obtained position information, group the destination terminal apparatuses present in the particular area together as a terminal apparatus group,select a representative server terminal apparatus from the terminal apparatuses included in the terminal apparatus group,transmit group information related to the terminal apparatuses included in the terminal apparatus group to each of the terminal apparatuses included in the terminal apparatus group,create data map information indicating a delivery rule for delivering the delivery data from the representative server terminal apparatus to another terminal apparatus within the terminal apparatus group,add information for identification of the representative server terminal apparatus to the created data map information, and transmit the data map information to each of the terminal apparatuses included in the terminal apparatus group, andinstruct a delivery data server to deliver the delivery data to the representative server terminal apparatus; and a terminal apparatus configured to
transmit the position information of the terminal apparatus to the controlling apparatus,receive the group information and data map information transmitted from the controlling apparatus, andobtain the delivery data that the representative server terminal apparatus has obtained from the delivery data server, by communicating, in accordance with the received data map information, with the another terminal apparatus within the terminal apparatus group included in the received group information. |
