Abstract

A method for determining when a wireless communications device'"'"'s warranty period begins uses the wireless communications device'"'"'s first use date as a proxy for the start of the warranty period. After being powered-on, the wireless communications device checks a non-volatile warranty registration status-flag. If that flag indicates that the wireless communications device has not previously registered, the wireless communications device sends a unique identifier, such as a serial number, to a warranty registration center. The warranty registration center stores the identifier with an associated registration date stamp. The wireless communications device then changes the warranty registration status flag to indicate that the device has been registered for warranty purposes. Once this automated warranty registration is complete, the wireless communications device proceeds with normal operation. The recorded first use date may be used as the start of the warranty period.

Claims

1. A communications device, comprising:

a) memory having stored therein;

i) a unique identifier for the communications device;

ii) a warranty registration status indicator;

b) a transmitter in communication with said memory; and

c) wherein said transmitter automatically sends a message containing said unique identifier to a warranty registration center to cause a warranty period to start.

2. The communications device of claim 1 further comprising a receiver for receiving an acknowledgment from said warranty registration center indicating that the warranty period associated with the communications device has started.

3. The communications device of claim 2 wherein said warranty registration status indicator is changed in response to receipt of said acknowledgement.

4. The communications device of claim 1 further comprising an antenna coupled to said transmitter, an operator interface, and a logic circuit for controlling the communications device and in communication with said transmitter, said memory, and said operator interface.

5. The communications device of claim 1, wherein the memory further includes routing information and wherein said communications device automatically communicates with said warranty registration center using said routing information immediately after activation of the communications device to send said message to said warranty registration center.

6. The communications device of claim 5, wherein the communications device is a mobile radio and the communication between said device and said warranty registration center is via a wireless communications network.

7. The communications device of claim 1, wherein said warranty registration status indicator is set to a first predetermined value prior to starting the warranty period and to second predetermined value in response to the warranty period being started.

8. The communications device of claim 1, wherein, if the communications device is operating in a digital network,:

a) the communications device is either a digital mobile phone or dual-mode mobile phone; and

b) said message is formatted and transmitted according to either a short message service or a data communications service.

9. The communications device of claim 1, further including a DTMF generator and wherein:

a) the communications device is either an analog mobile phone or dual-mode mobile phone operating in an analog mode; and

,

b) said message is formatted and transmitted in DTMF tones.

10. The communications device of claim 9, further comprising a tone detector for interpreting signals from said warranty registration center.

11. A communications device, comprising:

a) memory having stored therein;

i) a unique identifier for the communications device;

ii) a warranty registration status indicator;

iii) routing information;

b) a transmitter;

c) an antenna coupled to said transmitter;

d) an operator interface;

e) a logic circuit for controlling the communications device and in communication with said transmitter, said memory, and said operator interface;

f) wherein said transmitter automatically sends a message containing said unique identifier to a warranty registration center using said routing information to cause a warranty period to start;

g) a receiver coupled to said antenna for receiving an acknowledgment from said warranty registration center indicating that the warranty period associated with the communications device has started; and

h) wherein said warranty registration status indicator is set to a first predetermined value prior to starting the warranty period and to second predetermined value in response to said acknowledgement.

12. The communications device of claim 11, wherein the communications device is a mobile radio and wherein the sending of said message is via a wireless communications network.

13. The communications device of claim 11, wherein, if the communications device is operating in a digital network,:

a) the communications device is either a digital mobile phone or dual-mode mobile phone; and

b) said message is formatted and transmitted according to either a short message service or a data communications service.

14. The communications device of claim 11, further including a DTMF generator and wherein:

a) the communications device is either an analog mobile phone or dual-mode mobile phone operating in an analog mode; and

,

b) said message is formatted and transmitted in DTMF tones.

15. The communications device of claim 14, further comprising a tone detector for interpreting signals from said warranty registration center.
