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.

Claims

1. A mobile phone system, comprising:

a) a first mobile phone containing non-voice data comprising images taken by a camera integrated into said first mobile phone and digital data,

b) a data packetizer to form said non-voice data for transmission to a second mobile phone,

c) said first mobile phone coupled to said second mobile phone by radio signals to a mobile phone system,

d) said non-voice data (NVD) sent to said second mobile phone concurrent with speech by user of said first mobile phone, wherein said NVD formed into data packets by said data packetizer whereupon said data packets intermingled with voice data under control of a transmission and flag handler of said first mobile phone, and wherein the transmission and flag handler requests said data packets from said data packetizer when said flag indicates an absence of voice data,

e) said second mobile phone receives the NVD intermingled with speech from the first mobile phone, wherein information bits connected to a receiving transmission handler identify NVD being sent to the second mobile phone and wherein a transmission data receiver communicates with said packetizer to allow NVD packets to be sent from a transmission radio subsystem, whereby a receiving transmission handler separates the NVD from the transmission from the first mobile phone to allow the transmission data receiver to couple the NVD data to a flash memory and then an LCD viewing screen on the second mobile phone.

2. The system of claim 1, wherein said non-voice data is sent to said second mobile phone within unused signal frames located between speech signal frames.

3. The system of claim 2, wherein said non-voice data stored in a flash memory on said first mobile phone is formed into packets of data and said packets are transmitted to said second mobile phone within said unused signal frames.

4. The system of claim 1, wherein said non-voice data is digital data.

5. The system of claim 1, wherein said non-voice data is digital picture data.

6. The system of claim 1, wherein said non-voice data is digital picture data taken with a digital camera integrated together with said first mobile phone.

7. The system of claim 1, wherein said non-voice data received by said second phone is requested to be retransmitted if said second phone determines said data to be corrupted.

8. The system of claim 1, wherein said non-voice data transmitted to said second mobile phone, which is determined not to be corrupted, is stored in a memory in said second mobile phone.
