An aggregation device performs a synchronous processing so that a synchronous delivery may be made from a plurality of base stations through a broadcasting channel. A BSN (104) gives, when it sends broadcasting data for the synchronous delivery to an AN (102) and an AN (103), a period number and a sequence number are added to the broadcasting data so that the data to be sent from the AN (102) and the AN (103 can be synchronously delivered.
