Abstract: Message transmission device, which performs processing concerning the transmission of messages to the terminal, executes notification processing for the transmission of a trigger packet to the terminal, said trigger packet indicating that an unsent message exists. Preparatory processing for transmission of the message to the terminal is executed. The order in which the notification processing and the preparatory processing is executed is determined in such a manner that the preparatory processing has been completed before a message acquisition request, which is a response for the trigger packet, is received from the terminal.

Abstract: A communication apparatus is provided with a communication part, a response index calculation part, and a determination part. The communication part is configured to be capable of transmitting a packet to the terminal, via frequency carrier(s) of a base station to which the terminal is connected. The response index calculation part calculates a response index of the packet. The determination part determines the number of frequency carrier(s) used by the terminal in accordance with the result of the response index calculation by the response index calculation part. Determining a number of frequency carriers being used includes determining the number of LTE carrier waves being used by the terminal.
