Abstract
In A message exchange method, a wireless terminal transmits to a wireless base station a message parameter which includes identification information identifying a trigger message and a message size indicating the data length of a message, which is to be transmitted from the wireless terminal to the wireless base station. The trigger message is a message to trigger transmission of the message to be transmitted. Next, the wireless base station transmits the trigger message to the wireless terminal, and thereafter allocates to the wireless terminal a wireless bandwidth corresponding to the message size of the message to be transmitted. Further, the wireless base station transmits to the wireless terminal allocation information indicating the allocated wireless bandwidth. Then, the wireless terminal transmits the message to be transmitted, to the wireless base station by using the wireless bandwidth indicated by the allocation information.
