ABSTRACT:
A communication device has a data application and a voice application. The device establishes a data session between the data application and a data system. During the data session, the device receives a voice session request from a voice communication system, and in response, alerts the user of the request and transfers a voice session request indication from the voice application to the data application. The device receives user acceptance of the voice session request, and in response, transfers a voice session acceptance indication from the voice application to the data application. In response to the voice session indications, the device transfers a data session message from the data application to the data system and then transfers a ready indication from the data application to the voice application. In response to the ready indication, the communication device then transfers a voice session acceptance from the voice application to the voice communication system.
