Abstract
Techniques to configure quality of service (QoS) and utilize radio resources for a call in a WLAN are described. In an aspect, a station ensures that an access point in the WLAN is suitable for receiving service prior to performing registration to receive services via the WLAN. In another aspect, the station first requests for radio resources for traffic flows, then requests for radio resources for signaling flows, and sends signaling as best effort traffic if radio resources are not granted for the signaling flows. In yet another aspect, the station aggregates QoS for multiple applications and requests for radio resources based on the aggregated QoS. In yet another aspect, the station releases extra radio resources corresponding to the difference between the QoS granted by the WLAN and the QoS proposed by a remote terminal for the call. In yet another aspect, the station requests for the same QoS or lower from a new access point during handoff.
