Method and apparatus for automatic dialing in mobile radio telephone systems

Claim 7

The method of claim 3 including the step of delaying the automatic detecting step until a selective number of the initial connection signals have been transmitted.

Claim 8

The method of claim 3 wherein the automatic detecting step comprises the steps of: providing an audio filter circuit having input and output terminals and a plurality of switched elements; electrically connecting the communication channel to the input terminals of the audio filter circuit; selectively switching one or more of the switched elements into the filter circuit between the input and outout terminals to sequentially vary the center frequency thereof; and detecting the presence of an audio signal at the output terminals of the audio filter circuit.

Claim 9

The method of claim 5 further comprising the further steps of: (d) automatically detecting the presence of a second dial tone on the communication channel; and (e) transmitting a plurality of second dialing signals in the second communication format upon said detection of the second dial tone.

Claim 10

The method of claim 3 further comprising the further steps of: (d) automatically detecting the presence of a second dial tone on the communication channel; and (e) transmitting a plurality of second dialing signals in the second communication format upon said detection of the second dial tone.

Claim 13

In a method of recording signals representing a plurality of telephone dialing sequences comprising the steps of detecting a first signal representing an identification, detecting a second signal representing a telephone dialing sequence, recording in a memory device memory signals representing said second signal at a location in said memory device determined by the first signal, the improvement wherein said second signal is located adjacent said first signal, and wherein the location at which said first and second signals is recorded is immediately adjacent previously recorded memory signals.

Claim 14

In a method of recording signals representing a plurality of telephone dialing sequences comprising the steps of detecting a first signal representing an identification, detecting a second signal representing a telephone dialing sequence, recording in a memory device memory signals representing said second signal at a location in said memory device determined by the first signal, the improvement wherein said second signal is located adjacent said first signal, and wherein the location at which said first and second signals is recorded is immediately adjacent previously recorded memory signals.

Claim 15

An electronic apparatus for recording and dialing telephone dialing sequences comprising: (a) command input means for selectively generating input signals, at least one of said input signals representing digits of a telephone dialing sequence and others of said input signals representing reference digits; (b) memory means comprising a plurality of sequential memory locations; (c) memory control means responsive to said command input means for retrieving said input signals representing digits of a telephone dialing sequence from said memory means and storing additional ones of said input signals representing both reference digits and digits of a telephone dialing sequence into said memory means in the next sequential memory location unused for the storage of others of said input signals; and (d) dialing means responsive to said memory control means for generating telephone dialing signals corresponding to a selected telephone dialing sequence.

Claim 16

An electronic apparatus for recording and dialing telephone dialing sequences comprising: (a) command input means for selectively generating input signals, at least one of said input signals representing digits of a telephone dialing sequence and others of said input signals representing reference digits; (b) memory means comprising a plurality of sequential memory locations; (c) memory control means responsive to said command input means for retrieving said input signals representing digits of a telephone dialing sequence from said memory means and storing additional ones of said input signals representing both reference digits and digits of a telephone dialing sequence into said memory means in the next sequential memory location unused for the storage of others of said input signals; and (d) dialing means responsive to said memory control means for generating telephone dialing signals corresponding to a selected telephone dialing sequence.

Claim 21

A mobile telephone comprising: a transceiver operable to receive and transmit signals; keyboard means including a plurality of individually operable keys for entering numeric and function control commands, representing a standard multifrequency tone array and a predetermined number of control functions; first signalling means responsive to said keyboard means to generate dialing signals in a first predetermined communications format; second signalling means responsive to said keyboard means to generate dialing signals in a second predetermined communications format; tone detecting means responsive to the receiver portion of said transceiver to detect the presence of supervisory tones; control means responsive to said keyboard means to selectively operatively connect said first signalling means to said transceiver thereby to transmit dialing signals in a first predetermined communications format, said control means also being responsive to said tone detection means to operatively connect said second signalling means to said transceiver for the transmission of subsequent dialing signals in said second predetermined communications format.

Claim 22

A mobile telephone comprising: a transceiver operable to receive and transmit signals; keyboard means including a plurality of individually operable keys for entering numeric and function control commands, representing a standard multifrequency tone array and a predetermined number of control functions; first signalling means responsive to said keyboard means to generate dialing signals in a first predetermined communications format; second signalling means responsive to said keyboard means to generate dialing signals in a second predetermined communications format; tone detecting means responsive to the receiver portion of said transceiver to detect the presence of supervisory tones; control means responsive to said keyboard means to selectively operatively connect said first signalling means to said transceiver thereby to transmit dialing signals in a first predetermined communications format, said control means also being responsive to said tone detection means to operatively connect said second signalling means to said transceiver for the transmission of subsequent dialing signals in said second predetermined communications format.

Claim 23

The mobile telephone of claim 13 including: memory means for storing signals representative of at least one previously entered digit of numeric information as entered from said keyboard means; and second control means responsive to said keyboard means for retrieving signals stored in said memory means, said first and second signalling means being also responsive to said second control means.
