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.
