Abstract
A radio terminal and a radio communication system using the same, which enables power saving, the improvement of the quality of real-time communication such as voice communication, and a reduction of packet delay. An intermittent receiving interval for each radio terminal is set according to the operation mode of each application running on the radio terminal. Consequently, the intermittent receiving interval can be changed in cooperation with the operation mode of each application. Thus, power-saving control for the radio terminal can be carried out precisely. In addition, the radio terminal can assign priorities to data transmitted from the radio base station. The priorities are set according to the operation mode of each application running on the radio terminal, and the packets of real-time communication can be transmitted preferentially.
