The present invention discloses a method to operate phone using a single key, first provide method to form ‘key value’: (1) When the key is just closed, plus 1 to the ‘key value’, (2) When the key closing time is greater than time t1, form ‘closing key value’, (3) When the key closing time is smaller than t1 and the immediate key releasing time is greater than t2, store the key value as ‘releasing key value’, (4) When the key closing time is smaller than t1 and the immediate key releasing time is smaller than t2, skip to step (1). The ‘releasing key values’ can be used to represent the numerical and alphabetical keys on typical keypad of phone, while the ‘closing key values’ can be used to represent the function key on typical keypad of phone, so that the complete function of a typical phone keypad can be realized using only one key. Therefore, a phone can be made very small, which can be especially useful when installed on small Bluetooth device that connects to phone, since not only can it answer incoming phone calls, but also making outgoing phone calls. 1. A method to operate phone using a single key , characterized in that: the method is realized with a single key through the following steps:(1) when the key is just closed, plus 1 to the ‘key value’,(2) judging if the key closing time is less than t1, if yes, skip to step (3); otherwise, skip to step (4);(3) judging if the key releasing time is less than t2, if yes, skip to step (1); otherwise, store the key value as the ‘releasing key value’, exit the key value forming process, and trigger the ‘releasing key value processing procedure’;(4) store the ‘key value’ as the ‘closing key value’, exit the key value forming process, and trigger the ‘closing key value processing procedure’;(5) the key statues enters idle mode and the key value is set to zero;wherein the said step (3), when dialing the phone number associated with the ‘releasing key value’, each time when the key is pressed, a prompt tone corresponding ...
