Abstract: Techniques for monitoring radio and network conditions to improve performance for a wireless device are described. A diagnostic monitoring module may receive diagnostic messages from a modem via a diagnostic interface at the wireless device. The module may process (e.g., parse) the diagnostic messages to obtain network status information indicative of the status of a radio network. The module may provide the network status information to an application for use to control communication with the radio network. The module may also process the diagnostic messages to obtain diagnostic information indicative of the performance of a radio connection or a data session or both for the wireless device. The module may send the diagnostic information to a network server for network monitoring, debugging, etc.
