Abstract

A cellular radiotelephone which includes a programmable memory location which is programmed with a unique initial identification number is remotely programmed by providing the initial identification number to a cellular system, and establishing a page from the cellular system to the radiotelephone using the initial identification number to identify the radiotelephone. Data, including a mobile identification number, is transmitted during the page, and the programmable memory location is programmed with the mobile identification number. Accordingly, the radiotelephone can be conveniently programmed after purchase from a remote location. In addition, the initial identification number may comprise predetermined digits chosen from the electronic serial number.

Claims

1. A method for remotely programming a cellular radiotelephone which includes a programmable memory location which is programmed with a unique initial identification number, said remotely programming method comprising the steps of:

providing said initial identification number to a cellular system;

establishing a page from said cellular system to said radiotelephone using said initial identification number to identify said radiotelephone;

transmitting data to said radiotelephone during said page, wherein said data comprises a mobile identification number; and

reprogramming said programmable memory location so that said programmable memory location is programmed with said mobile identification number.

2. A method according to claim 1 wherein said data comprises a Short Message Service data string.

3. A method according to claim 2 wherein said Short Message Service data string comprises a data format defined by the IS-136 air interface standard and the IS-41C network standard.

4. A method according to claim 1 wherein said providing step comprises the steps of:

establishing a cellular radiotelephone communication from said radiotelephone to the cellular system;

transmitting said initial identification number to said cellular system; and

terminating said first cellular radiotelephone communication.

5. A method according to claim 1 wherein said radiotelephone comprises a non-programmable memory location for storing a unique telephone serial number, wherein said initial identification number comprises predetermined digits chosen from said telephone serial number.

6. A method according to claim 5 wherein said telephone serial number comprises an electronic serial number (ESN) of said radiotelephone.

7. A method according to claim 5 wherein said providing step further comprises the step of providing said telephone serial number to said cellular system, and said providing step is followed by the step of comparing said telephone serial number and said initial identification number.

8. A method according to claim 1 wherein said providing step further comprises providing account information to said cellular system.

9. A method according to claim 8 wherein said providing step is followed by the step of establishing a cellular service account for said radiotelephone.

10. A method for remotely programming a cellular radiotelephone which includes a programmable memory location which is programmed with a unique initial identification number, said remotely programming method comprising the steps of:

establishing a first cellular radiotelephone communication from said radiotelephone to a cellular system;

transmitting said initial identification number to said cellular system during said first cellular radiotelephone communication;

terminating said first cellular radiotelephone communication;

establishing a second cellular radiotelephone communication from said cellular system to said radiotelephone using said initial identification number to identify said radiotelephone;

transmitting a mobile identification number to said radiotelephone during the second cellular radiotelephone communication; and

reprogramming said programmable memory location so that said programmable memory location is programmed with said mobile identification number.

11. A method according to claim 10 wherein said radiotelephone further comprises a non-programmable memory location for storing a unique telephone serial number, wherein said initial identification number comprises predetermined digits chosen from said telephone serial number.

12. A method according to claim 11 wherein said telephone serial number comprises an electronic serial number (ESN) of said radiotelephone.

13. A method according to claim 11 wherein said first transmitting step further comprises the step of transmitting said radiotelephone serial number to said cellular system during said first cellular radiotelephone communication, and said first transmitting step is followed by the step of comparing said radiotelephone serial number and said initial identification number.

14. A method according to claim 10 wherein said first transmitting step further comprises transmitting account information to said cellular system.

15. A method according to claim 14 wherein said first transmitting step is followed by the step of establishing a cellular service account for said radiotelephone.

16. A method according to claim 10 wherein said second cellular radiotelephone communication comprises a page.

17. A method according to claim 16 wherein said second transmitting step comprises the step of transmitting a Short Message Service data string to said radiotelephone, wherein said Short Message Service data string comprises said mobile identification number.

18. A method according to claim 16 wherein said Short Message Service data string comprises a data format defined by the IS-136 air interface standard and the IS-41C network standard.

19. A method according to claim 10 wherein said cellular radiotelephone includes a second programmable memory location which is programmed to a first boolean value indicating that the first programmable memory location is programmed with the initial identification number, and wherein said reprogramming step is followed by the step of reprogramming said second programmable memory location to a second boolean value.

20. A method according to claim 10 wherein said reprogramming step is followed by the step of transmitting a response to said cellular system to indicate successful reprogramming of said programmable memory location.

21. A remotely programmable cellular radiotelephone comprising:

a non-programmable memory location for storing a unique telephone serial number;

a programmable memory location programmed with an initial identification number wherein said initial identification number comprises predetermined digits chosen from said telephone serial number;

transceiver means for transmitting and receiving cellular radiotelephone communication signals to and from a cellular system; and

programming means for reprogramming said programmable memory location in response to receipt of a mobile identification number from said transceiver means so that said programmable memory location is programmed with said mobile identification number.

22. A remotely programmable cellular radiotelephone according to claim 21 wherein said unique telephone serial number is an electronic serial number (ESN) of said radiotelephone.

23. A remotely programmable cellular radiotelephone according to claim 22 wherein said initial identification number comprises the 10 least significant digits of said electronic serial number.

24. A remotely programmable cellular radiotelephone according to claim 21 wherein said transceiver means comprises

means for establishing a cellular radiotelephone communication from said radiotelephone to said cellular system, and

means for transmitting said initial identification number to said cellular system during said cellular radiotelephone communication.

25. A remotely programmable cellular radiotelephone according to claim 24 wherein said transceiver means further comprises means for transmitting said unique radiotelephone serial number.

26. A remotely programmable cellular radiotelephone according to claim 24 wherein said transceiver means further comprises means for transmitting account information to said cellular system.

27. A remotely programmable cellular radiotelephone according to claim 21 wherein said transceiver means comprises page receiving means for receiving a page from said cellular system, wherein said radiotelephone is identified by said initial identification number and said page comprises said mobile identification number.

28. A remotely programmable cellular radiotelephone according to claim 27 wherein said page comprises a Short Message Service data string.

29. A remotely programmable cellular radiotelephone according to claim 28 wherein said Short Message Service data string comprises a data format defined by the IS-136 air interface standard and the IS-41C network standard.
