Abstract
A method is described by which digital data can be sent between mobile phones concurrent with speech during a same phone call. The digital data can be from a digital camera that is integrated with the mobile, or cellular, phone. The discontinuous transmission system of the mobile phone system is modified to include a transmission handler that is used to control the packetizing of the digital data to be transmitted within the voids in the transmitted speech determined by a voice activated detector. A reception handler is added to the discontinuous transmission system to allow the extraction of the digital data from the transmitted mobile phone system signal.
