Methods, systems, and devices are described for improving inter-network mobility performance in multiple network wireless communication systems by using channel avoidance information from a first network using a first radio access technology (RAT) to modify inter-RAT behavior of a second network using a second RAT. In some embodiments, the second network queries the first network for channel avoidance information and applies the channel avoidance information in suppressing inter-RAT channel measurements, avoiding inter-RAT redirection, and/or avoiding inter-RAT reselection. In embodiments, inter-RAT channel measurement suppression, inter-RAT redirection avoidance, and/or inter-RAT reselection avoidance is performed by the mobile device. In other embodiments, channel avoidance information of the first network may be communicated to other network entities of the second network and one or more of these entities may modify various inter-RAT behaviors.
