Abstract

A system and method for forwarding a telephone call includes routing a telephone call from a calling party to a first telephone of a called party. A determination may be made that the telephone call was not answered by the called party. A determination may be made as to whether the telephone call is to be forwarded to an unrelated second telephone within a predetermined distance of the first telephone. Geographic coordinates of the first telephone may be determined. A determination of geographic coordinates of at least one second telephone may be made. A determination as to whether the at least one unrelated second telephone is within the predetermined distance of the first telephone. An unrelated second telephone determined to be within the predetermined distance of the first telephone may be selected. The telephone call may be forwarded to the selected unrelated second telephone.

Claims

1. A method for forwarding a telephone call, said method comprising:

routing a telephone call from a calling party to a first telephone of a called party;

determining that the telephone call was not answered by the called party;

determining whether the telephone call is to be forwarded to another telephone within a predetermined distance of the first telephone of the called party;

determining geographic coordinates of the first telephone;

determining geographic coordinates of at least one unrelated second telephone;

determining whether the at least one unrelated second telephone is within the predetermined distance of the first telephone;

selecting an unrelated second telephone determined to be within the predetermined distance of the first telephone; and

forwarding the telephone call to the selected unrelated second telephone.

2. The method according to claim 1, further comprising determining whether the called party has activated an emergency call forwarding service.

3. The method according to claim 1, further comprising, in response to determining that the telephone call was not answered by the called party, playing a message to the calling party to enable the calling party to selectively enable the telephone call to be forwarded to the unrelated second telephone.

4. The method according to claim 1, further comprising receiving an emergency call code and, in response to determining that the telephone call was not answered by the called party, causing the determination of whether the telephone call is to be forwarded to be positive.

5. The method according to claim 4, wherein receiving the emergency call code includes receiving the emergency call code as a prefix to the telephone number of the called party.

6. The method according to claim 1, wherein determining the geographic coordinates of the first telephone includes receiving Global Positioning System (GPS) coordinates from the first telephone.

7. The method according to claim 1, further comprising:

playing a message to a user of the unrelated second telephone to notify the user that the telephone call for the calling party within the predetermined range of the user is being re-routed from the first telephone that was not answered;

enabling the user to accept or reject the telephone call; and

in response to the user accepting the telephone call, forwarding the telephone call to the unrelated second telephone.

8. The method according to claim 1, wherein determining whether the telephone call is to be forwarded to the unrelated second telephone within the predetermined distance of the first telephone includes determining whether the unrelated second telephone is within approximately 30 feet.

9. The method according to claim 1, wherein forwarding the telephone call from a calling party to the unrelated second telephone includes forwarding the telephone call to a mobile telephone.

10. The method according to claim 9, wherein determining geographic coordinates of at least one unrelated second telephone includes determining geographic coordinates of at least one mobile telephone.

11. A system for forwarding a telephone call, said system comprising:

an input/output I/O) unit configured to communicate over a communications network;

a storage unit configured to store a data repository, the data repository including telephone numbers of telephones and respective geographic coordinates of the telephones;

a processing unit in communication with said I/O unit and storage unit, said processing unit configured to;

route a telephone call from a calling party to a first telephone of a called party;

determine that the telephone call was not answered by the called party;

determine whether the telephone call is to be forwarded to another telephone within a predetermined distance of the first telephone of the called party;

determine geographic coordinates of the first telephone;

determine, from information stored in the data repository, geographic coordinates of at least one unrelated second telephone;

determine whether the at least one second telephone is within the predetermined distance of the first telephone;

select an unrelated second telephone determined to be within the predetermined distance of the first telephone; and

forward, via the I/O unit, the telephone call to the selected unrelated second telephone.

12. The system according to claim 11, wherein said processing unit is further configured to determine whether the called party has activated an emergency call forwarding service.

13. The system according to claim 11, wherein said processing unit is further configure to, in response to determining that the telephone call was not answered by the called party, play a message to the calling party to enable the calling party to selectively enable the telephone call to be forwarded to the unrelated second telephone.

14. The system according to claim 11, wherein said processing unit is further configured to receive an emergency call code and, in response to determining that the telephone call was not answered by the called party, cause the determination of whether the telephone call is to be forwarded to be positive.

enable the user to accept or reject the telephone call; and

in response to the user accepting the telephone call, re-route the telephone call to the unrelated second telephone.

19. The system according to claim 11, wherein the unrelated second telephone is a mobile telephone.

20. The system according to claim 19, wherein the geographic coordinates of at least one second telephone are geographic coordinates of at least one mobile telephone.
