Abstract: One aspect of the present invention can include a dual transmit mobile communication device that includes multiple modems, a modem controller, and a data session manager. The modem controller can programmatically control the modems. The data session manager can manage data sessions of the mobile communication device. The data session manager can programmatically interact with the software modem controller to ensure that only one of the modems is transmitting at any one time. States of data communication sessions can be automatically adjusted as necessary. For example, the modem controller can block transmissions over a data traffic channel in order to use a modem other than one associated with the data traffic channel, such as using a modem to handle a dispatch session. The data session manager can preserve state information of blocked data sessions, so that the sessions can be resumed when a modem is available.

Abstract: A system and method for a dual mode device to intelligently handle incoming communications can include a mobile communication device and a notification engine. The mobile communication device can have more than one communication mode. The notification engine can perform an intelligent notification action whenever the mobile communication device is actively engaged in a communication session and an incoming call for a new session is received. The active session and the new session can correspond to different communication modes that are unable to be concurrently used. One configuration for an intelligent notification can be to selectively notify the mobile device user of the call depending upon a caller's importance level Another configuration for the intelligent notification can be to notify a blocked caller that the called device is busy or is actively being used for communications involving the original communication mode.
