Message injection system and method

A mobile communication device including an application unit including an application unit running in a first memory, a radio transmission unit operating in a second memory and communicatively coupled to the application unit, and an audio switching unit communicatively coupled to the application unit and the radio transmission unit, the mobile communication device performing the method of:

• transferring an incoming call notification from the radio transmission unit to the application unit;
• identifying formation provided from the radio transmission unit to the application unit;
• based upon the information identified, transferring a call acceptance notification from the application unit to the radio transmission unit that causes the radio transmission unit to establish a two way communication with the device calling the device over a wireless network,
• opening an audio path from the application unit to the radio transmission unit in the audio switching unit, and
• transmitting an audio signal from the application unit to the wireless network;
• or
• trasmitting a different audio message depending on information provided from the radio transmission unit to the application unit;
• and
• closing the audio path in the audio switching unit when the audio has been completely transferred.

A mobile communication device including:

• an application unit including
• an application running in a first memory of the device,
• an application video unit in the first memory, the application video unit being communicatively coupled to the application, and
• a telephony unit in the first memory, the telephony unit being communicatively coupled to the application;
• a radio transmission unit including
• a radio interface unit operating, in a second memory and communicatively coupled to the telephony unit,
• a radio video unit operating in the second memory, the radio video unit being communicatively coupled to the radio interface unit, and
• a hardware driver unit communicatively coupled to the radio interface unit, the hardware driver unit being configured to initiate a communication connection between the mobile communication device and another device;
• and
• a video switching unit communicatively coupled to the application unit and the radio transmission unit,
• wherein the application transmits a video signal stored in the first memory over a wireless network via the video switching unit and radio interface unit, and
• wherein the application unit transmits a signal different from the video signal depending upon information provided from the radio interface unit to the application unit.
