A method for application-based radio access technology (RAT) switching is provided. The method can include engaging in data communication for the application over a connection to a first RAT and measuring a connection quality metric of the connection to the first RAT. The method can further include determining a threshold connection quality metric for an application. The threshold connection quality metric can be defined for the application and can be different from a second threshold connection quality metric defined for a second application. The method can also include comparing the measured connection quality metric to the threshold connection quality metric. The method can additionally include switching from the first RAT to a second RAT and engaging in data communication for the application over the second RAT in an instance in which the quality metric does not satisfy the threshold connection quality metric.
