Abstract
A technique for improving the efficiency of downloading transmission data is disclosed. An information downloading apparatus downloads differing sets of information to predetermined groups to which a mobile terminal may belong. This apparatus includes a channel selecting unit for selecting from plural information channels an information channel for transmitting transmission data and a transmitting unit for transmitting transmission data using the selected information channel. The channel selecting unit selects an information channel so that sets of transmission data with differing destination addresses may be transmitted through differing information channels. The transmitting unit transmits to each group, through a control channel, information pertaining to whether a set of transmission data exists, the information channel to be used if the set of transmission data exists, and the data length of the set of transmission data. The control channel includes time slots that are associated with the groups.
