In some embodiments, a cellular baseband processor communicates wirelessly and reports cellular metrics for both a first cellular RAT and a second cellular RAT. The cellular baseband processor may be configured to tune away, for a time interval, from the first cellular RAT to monitor for communications on the second cellular RAT. In some embodiments, the cellular baseband processor is configured not to report cellular metrics during the time interval to prevent a RAT manager from setting up a connection for voice calls on a WLAN RAT during the time interval. In some embodiments another processing element the RAT manager is configured to ignore cellular metrics from the cellular baseband processor during the interval. This may reduce signal load and power consumption, in some embodiments.
