Communication system with handset for distributed processing
First Claim
1. A communication system, comprising:
- at least one mobile handheld telephone handset adapted to communicate via a wireless telephony medium with a telephone network handling system,wherein said handset comprises;
(a) means to receive input from a user and produce first signals dependent thereupon,(b) means to adapt at least a portion of said first signals to produce a voice transmission signal as part of a telephone conversation with a third party, and(c) means to transmit said voice transmission signal via said wireless telephony medium,(d) first processing means adapted to carry out a first processing step in a handwriting recognition process on selected ones of said first signals and produce data dependent thereupon, wherein said selected first signals comprise handwriting signals input via a touch sensitive screen on said handset and the first processing step preserves predetermined information necessary to carry out a remote second processing step,(e) means to adapt said data according to a wireless telephony protocol to produce a data transmission signal modulated according to a facsimile protocol, wherein said data transmission signal includes predetermined graphic features of said input to enable said second processing means to carry out the remaining steps of said handwriting recognition process, and(f) means to transmit said data transmission signal via said wireless telephony medium to said telephone network handling system; and
wherein said telephone network handling system comprises;
(a) means to receive said voice transmission signal,(b) means to forward said voice transmission signal to said third party,(c) means to receive and process said data transmission signal from said handset to regenerate said data, and(d) second processing means positioned remote from said handset and adapted to carry out said remote second processing step in a handwriting recognition process on said regenerated data, and to produce second signals dependent thereupon.

Abstract
A communication system comprising at least one mobile handheld telephone handset adapted to communicate via a wireless telephony medium with a telephone network handling system.
The handset comprises input devices to receive input from a user and produce signals dependent thereupon, an onboard processor to adapt speech input to produce a voice transmission signal as part of a telephone conversation with a third party; and an antenna to transmit the voice transmission signal via the wireless telephony medium.
The telephone network handling system comprises a receiver to receive the voice transmission signal, and means to forward the voice signal to a third party.
The handset further comprises a first processor to carry out a first processing step on selected input signals and produce data dependent thereupon which preserves predetermined information necessary to carry out a remote second processing step, an onboard processor to adapt the data according to a conventional wireless telephony protocol to produce a transmission signal, and an antenna to transmit the transmission signal via the wireless telephony medium to the telephone network handling system.
The system further comprises a remote processor adapted to receive and adapt the transmission signal from the telephone network handling system to regenerate the data, and to carry out a second processing step on the data and produce an output dependent thereupon.
