Abstract

A unique a method for memory dialing for cellular telephones includes storing a recall sequence having a variable number, and replacing the variable number with a directory number in response to a prompt from the telephone when employing memory dialing. In particular, the method comprises the steps of selecting a memory location in a telephone for designating a recall sequence and storing within the memory location the recall sequence including at least one predetermined number which is automatically dialed by the cellular telephone and at least one variable number to be inserted by the user (59); accessing a memory location (60); responding to a prompt from the telephone (64); and replacing the variable number to complete a calling sequence (66). Finally, the present method provides for the transmission of both data and DTMF tones.

Claims

1. A method for memory dialing for cellular telephones comprising the steps of:

accessing one of a plurality of a dedicated memory locations having stored therein a recall sequence including an ordered linking of at least one predetermined number to be automatically dialed by said cellular telephone and at least one variable number to be inserted by a user;

replacing said at least one variable number in said recall sequence with a number to complete a dialing sequence in response to a prompt from said cellular telephone;

transmitting a portion of said recall sequence as data on an access channel to establish a connection to a telephone network;

establishing a voice channel between said cellular telephone and said telephone network to transmit and receive audio signals; and

transmitting data signals representing the remaining portion of said recall sequence on said voice channel.

2. The method for memory dialing for cellular telephones of claim 1 wherein said at least one predetermined number is selected from the group consisting of:

an access number;

an area code;

prefix numbers;

system control commands; and

a personal identification number.

3. The method for memory dialing for a cellular telephone of claim 1 wherein said recall sequence includes a plurality of predetermined numbers.

4. The method for memory dialing for a cellular telephone of claim 1 wherein said recall sequence includes a plurality of variable numbers and said step of replacing includes replacing a plurality of variable numbers.

5. The method for memory dialing for cellular telephones system of claim 1 wherein said number to complete a dialing sequence is at least a portion of a directory number.

6. The method for memory dialing for cellular telephones of claim 1 wherein said recall sequence includes a pause command delineating said at least one predetermined number and said at least one variable number, said pause command establishing a predetermined delay wherein said recall sequence is continued immediately after said predetermined delay for fully automatic dialing.

7. The method for memory dialing for cellular telephones of claim 1 wherein said recall sequence includes a pause command delineating said at least one predetermined number and said at least one variable number, said pause command establishing a predetermined delay and a user prompt wherein said recall sequence will continue after a response to a user prompt.

8. The method for memory dialing for cellular telephones of claim 1 wherein said recall sequence further includes a first pause command as a prefix to signals which are to be sent as data and a second pause command as a prefix to signals which are to be sent as DTMF tones.

9. The method for memory dialing for cellular telephones of claim 1 wherein said step of transmitting data signals representing the remaining portion of said recall sequence includes transmitting DTMF signals.

10. The method for memory dialing for cellular telephones of claim 1 further including a step of recording the calling time of the call established by said recall sequence.

11. A method for memory dialing for cellular telephones comprising the steps of:

selecting one of a plurality of dedicated memory locations within said cellular telephone;

storing within said dedicated memory location a recall sequence including at least one predetermined number to be automatically dialed by said cellular telephone and at least one variable number to be inserted by the user;

accessing said dedicated memory location;

replacing said at least one variable number in said recall sequence with a number to complete a dialing sequence in response to a prompt from said cellular telephone;

transmitting a portion of said recall sequence as data on an access channel to establish a connection to a telephone network;

establishing a voice channel between said cellular telephone and said telephone network to transmit and receive audio signals; and

transmitting data signals representing the remaining portion of said recall sequence on said voice channel.

12. The method for memory dialing for cellular telephones of claim 11 wherein said predetermined number is selected from the group consisting of:

an access number;

an area code;

prefix numbers;

system control commands; and

a personal identification number.

13. The method for memory dialing for a cellular telephone of claim 11 wherein said recall sequence includes a plurality of predetermined numbers.

14. The method for memory dialing for a cellular telephone of claim 11 wherein said recall sequence includes a plurality of variable numbers and said step of replacing includes replacing a plurality of variable numbers.

15. The method for memory dialing for cellular telephones system of claim 11 wherein said number to complete a dialing sequence is at least a portion of a directory number.

16. The method for memory dialing for cellular telephones of claim 11 wherein said recall sequence includes a pause command delineating said at least one predetermined number and said at least one variable number, said pause command establishing a predetermined delay wherein said recall sequence is continued immediately after said predetermined delay for fully automatic dialing.

17. The method for memory dialing for cellular telephones of claim 11 wherein said recall sequence include a pause command delineating said at least one predetermined number and said at least one variable number, said pause command establishing a predetermined delay and a user prompt wherein said recall sequence will continue after a response to a user prompt.

18. The method for memory dialing for cellular telephones of claim 11 wherein said recall sequence further includes a first pause command as a prefix to signals which are to be sent as data and a second pause command as a prefix to signals which are to be sent as DTMF tones.

19. The method for memory dialing for cellular telephones of claim 11 wherein said step of transmitting data signals representing the remaining portion of said recall sequence includes transmitting DTMF signals.

20. The method for memory dialing for cellular telephones of claim 11 further including a step of recording the calling time of the call established by said recall sequence.
