PROBLEM TO BE SOLVED: To provide a method of determining, in utilizing radio resources for a call in a WLAN, required quality of service (QoS) to utilize just sufficient radio resources.SOLUTION: A station 110 in a WLAN ensures, prior to receiving service via the WLAN, that an access point 120a in the WLAN has a QoS adjustment function M2. After negotiating QoS required for traffic flows with the access point 120a, the station 110 establishes a communication session M4. When the traffic flows are based on a plurality of applications, aggregated QoS obtained by aggregating the QoS of them is negotiated. When granted QoS is beyond the QoS required by the station 110, the corresponding surplus radio resources are released. When handoff occurred in the communication session, the required QoS is negotiated with a new access point 120b M9. |
