<p><P>PROBLEM TO BE SOLVED: To provide a wireless LAN system which can be controlled so that specific data such as acoustic data are not destroyed by timeout inside a radio terminal on a transmission side without imposing large control loads on an entire system. <P>SOLUTION: In the wireless information communication system, a radio terminal 2a normally transmits a packet by a CSMA/CA system. In the packet, a time when a packet to be transmitted next without a break is destroyed inside the radio terminal 2a by timeout is embedded. Here, an AP1 monitors the information and, when the packet which the radio terminal 2a is about to send is almost destroyed by timeout inside the radio terminal 2a, a right of transmission by a polling system is imparted to the radio terminal 2a which is about to send the packet. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
