In an embodiment, an access network (AN) receives a message configured to prompt a conditional allocation of Quality of Service (QoS) resources to an access terminal (AT). The message can be received from the AT or from an application server (AS) that arbitrates a communication session for the AT. In another embodiment, if the AT determines that a QoS resource request has not yet been granted, the AT waits until the traffic channel (TCH) has been obtained for a communication session before resending the QoS resource request. In another embodiment, if the AT determines to initiate or join a second communication session before a confirmation that QoS resources for a first communication session are relinquished, the AT waits until the confirmation is received before a request for QoS resources for the second communication session is sent.
