Communication system, communication method and mobile station

摘要

The object of the present invention is to provide a communication system which makes it possible to avoid a control load from being generated while effectively utilizing the reception capabilities of mobile stations. The communication system includes a category manager configured to categorize reception capability values showing reception capabilities necessary for receiving multicast data in the mobile stations, a reception capability collector (33) configured to collect the reception capability values of the mobile stations, a decider (34) configured to decide a hierarchical structure of the multicast data from a plurality of categories corresponding to the collected reception capability values of the mobile stations and a transmitter (31) configured to transmit the multicast data using the decided hierarchical structure.
