Abstract
In a wireless communication system where a fixed radio bandwidth is used, a wireless communication apparatus and a usage bandwidth determination method that guarantee the QoS of real time application data without changing the configurations of the existing base station apparatus and IP network. A wireless resource control section (170) negotiates with a base station apparatus (20) when a wireless communication terminal apparatus (10) changes over from an idle mode to a communication mode, to determine a usable radio bandwidth. A bandwidth estimation section (180) estimates the available bandwidth for the non-real time application from the usable radio bandwidth and the required bandwidth for the real time application. An awnd estimation section (190) estimates the maximum awnd that shows the maximum amount of the packet that can be received in the wireless communication terminal apparatus (10) from the available bandwidth for the non-real time application.
