Abstract

A method and apparatus of call forwarding is presented whereby a wireless phone and one or more landline phones are equipped and programmed to perform call forwarding activation and de-activation automatically, without user intervention, based on geographic proximity relationships between the phones. When the wireless phone is not in near-proximity to any of the landline phones, calls to the landline phones are forwarded to the wireless phone. When the wireless phone comes in near-proximity to one of the landline phones, all calls to the wireless phone—including calls forwarded from other phones—are forwarded to the nearby landline phone. When the wireless phone subsequently leaves the nearby landline phone, all calls are sent to the wireless phone again. Advantageously, this arrangement overcomes numerous problems associated with manual activation and de-activation of call forwarding. In addition, the arrangement is entirely handset-based and requires no changes to network infrastructure, software, or established call forwarding procedures.

Claims

1. A method for automatically forwarding a call intended for a first phone to a second phone based upon the proximity of the first phone to the second phone, the method comprising the steps of:

detecting that the first phone is within range of the second phone; and

automatically forwarding calls intended for the first phone to the second phone upon detecting that the first phone is within range of the second phone.

2. A method for automatically forwarding a call in accordance with claim 1, the method further comprising detecting that the first phone is not within range of the second phone.

3. A method for automatically forwarding a call in accordance with claim 2, the method further comprising automatically forwarding calls intended for the second phone to the first phone upon detecting that the first phone is not within range of the second phone.

4. A method for automatically forwarding a call in accordance with claim 3, wherein automatic call forwarding is temporarily suspended upon entry of a code into the second phone.

5. A method for automatically forwarding a call in accordance with claim 1, the method further comprising deactivating automatically forwarding calls intended for the first phone to the second phone upon detecting that the first phone is not within range of the second phone.

6. A method for automatically forwarding a call in accordance with claim 5, wherein the step of deactivating is done by sending a predetermined key sequence from the first phone.

7. A method for automatically forwarding a call in accordance with claim 1, wherein the step of detecting that the first phone is within range of the second phone comprises receiving a signal sent from the second phone to the first phone.

8. A method for automatically forwarding a call in accordance with claim 7, wherein the step of receiving a signal sent from the second phone to the first phone comprises receiving a beacon message at the first phone from the second phone.

9. A method for automatically forwarding a call in accordance with claim 8, wherein the beacon message indicates that the first phone is equipped to provide automatic call forwarding.

10. A method for automatically forwarding a call in accordance with claim 8, wherein the beacon message indicates that the second phone is equipped to provide automatic call forwarding.

11. A method for automatically forwarding a call in accordance with claim 8, wherein the first beacon message received activates the automatic call-forwarding.

12. A method for automatically forwarding a call in accordance with claim 7, wherein the step of receiving a signal sent from the second phone to the first phone comprises receiving a low-range signal at the first phone.

13. A method for automatically forwarding a call in accordance with claim 1, wherein the step of automatically forwarding calls comprises performing, at the first phone, the steps necessary to activate call-forwarding.

14. A method for automatically forwarding a call in accordance with claim 13, wherein the step of performing, at the first phone, the steps necessary to activate call-forwarding comprises the step of sending the phone number of the first phone and the feature code needed to activate call forwarding.

15. A method for automatically forwarding a call in accordance with claim 1, the method further comprising programming the first phone with a forwarding phone number to which calls would be automatically forwarded.

16. A method for automatically forwarding a call in accordance with claim 15, wherein the forwarding phone number is the directory number of the second phone

17. A method for automatically forwarding a call in accordance with claim 1, the method further comprising the step of suspending the automatic forwarding of calls upon entering a pre-programmed key sequence in the first phone.

18. A method for automatically forwarding a call in accordance with claim 1, the method further comprising the step of suspending the automatic forwarding of calls upon entering a pre-programmed key sequence in the first phone

20. A phone in accordance with claim 19, wherein the low-range signal includes an indication that the second phone is capable of receiving forwarded calls from the phone.

21. A phone in accordance with claim 19, wherein the low-range signal is a beacon message sent from the second phone.

22. A phone in accordance with claim 19, wherein the processor generates low-range signals to be transmitted by the low-range transceiver.

23. A phone in accordance with claim 22, wherein the low-range signals sent by the low-range transmitter are sent to indicate the presence of the phone.

24. A phone in accordance with claim 19, wherein the processor deactivates call forwarding of calls intended for the phone when the low-range transceiver ceases to receive a low-range signal.

25. A phone in accordance with claim 19, wherein the processor receives a code from an input device coupled to the phone, and wherein the code indicates that the phone should suspend the automatic call forwarding.

26. A phone in accordance with claim 25, wherein the processor deactivates call forwarding of calls intended for the phone in response to the receipt of the code.

19. A phone that provides automatic call forwarding for calls intended for the phone, the phone comprising:

a low-range transceiver that receives a low-range signal, the low-range signal indicating the proximity of a second phone; and

a processor that sends a call forwarding activation signal to automatically forward calls intended for the phone to the second phone upon receiving the low-range signal.
