主权项

1. A data distribution apparatus comprising:
a processor to perform transmitting processing for transmitting updating data used for updating data stored in a wireless communication apparatus, wherein, when performing the transmitting processing, the processor transmits the updating data to a control apparatus which controls a multicast service bearer, transmits a message including setting information concerning settings of the multicast servicer bearer to the wireless communication apparatus, and transmits a distribution start request signal indicating a request to start distributing the updating data to the control apparatus wherein the processor further determines whether or not a message has been received from the wireless communication apparatus, and when a message has been received, the processor performs the transmitting processing, wherein, when the message received from the wireless communication apparatus is a first message, the processor transmits a message including the setting information to the wireless communication apparatus, when the message received from the wireless communication apparatus is a second message, the processor transmits a message indicating that the updating data will not be sent through the multicast service bearer to the wireless communication apparatus, and when messages received from a plurality of the wireless communication apparatuses include the first and second messages, the processor transmits the setting information to a wireless communication apparatus that has sent the second message.
