摘要
A core network apparatus notifies a piece of identification information on each service for receiving multicast data in a down link to an access network apparatus. The access network apparatus receives the piece of the identification information notified from the core network apparatus to capture a radio channel for the service identified by the piece of the identification information. The core network apparatus transmits the multicast data to the access network apparatus in a receivable form on the basis of the piece of the identification information. The access network apparatus receives the multicast data transmitted from the core network apparatus on the basis of the piece of the identification information and transmits the received multicast data to terminals over the radio channel.
