Claim Text:
1. A method for operating a wireless user equipment (UE) device, the method comprising: establishing a multiple radio bearer call via a wireless link with a network, the call having a circuit-switched radio bearer component and a packet-switched radio bearer component; determining that the packet-switched radio bearer component has been released by the network, wherein the UE device has packet data to be transmitted to the network when the packet-switched radio bearer component is released; determining that the UE device is in a first state of at least a first state and a second state with respect to RF conditions, wherein the first state substantially corresponds to poorer access stratum conditions than the second state; determining a Quality of Service (QoS) level of the packet data; selecting a buffer timer value for the packet data based at least in part on the QoS level of the packet data; and buffering the packet data until the earlier of expiration of the buffer timer or until the UE device enters the second state with respect to RF conditions based on determining that the packet-switched radio bearer component has been released by the network, based on determining that the UE device is in the first state with respect to RF conditions, and based on the QoS level of the packet data.
