A method for determining whether to allow performance of an inter-radio access technology (IRAT) transition is provided. The method can include a wireless communication device determining a realized quality of service (QoS) for packet switched data traffic on a first radio access technology (RAT); determining whether the realized QoS satisfies a threshold QoS; suspending IRAT transition to a second RAT in an instance in which it is determined that the realized QoS satisfies the threshold QoS; and allowing IRAT transition to the second RAT in an instance in which it is determined that the realized QoS does not satisfy the threshold QoS.
