Abstract

If a network (80) incurs blockage or if a called subscriber (200) is unreachable for network blockage or network or inter network errors, the network re-routes the calling subscriber (100). Instead of merely dropping a call or sending a re-order signal to the calling subscriber, the network automatically reroutes (52) the calling subscriber to a voice mail system (95) in the called subscriber'"'"'s home service network (80).

Claims

1. A method for network controlled call forwarding comprising the steps of

initiating by a first subscriber a call through a first network to a second subscriber;

transmitting the call from the first network to a second network;

returning an error message from the second network to the first network; and

forwarding the call from the first subscriber to an alternate destination by the first network.

2. The method for network controlled call forwarding as claimed in claim 1, wherein the step of forwarding the call from the first subscriber includes the step of forwarding the call from the first subscriber to a voicemail system by the first network.

3. The method for network controlled call forwarding as claimed in claim 1, wherein there is further included a step of requesting by the first network that the first subscriber leave a message due to network difficulties.

4. The method for network controlled call forwarding as claimed in claim 3, wherein there if further included a step of coupling the first subscriber to a voicemail system.

5. The method for network controlled call forwarding as claimed in claim 1, wherein there is further included steps of:

using session initiation protocol; and

the first and second networks are mobile internet protocol networks.

6. The method for network controlled call forwarding as claimed in claim 1, wherein there is further included a step of using by the first and second networks signaling system seven protocol.

7. The method for network controlled call forwarding as claimed in claim 1, wherein there is further included a step of using UMTS protocol by the first and second networks.

8. The method for network controlled call forwarding as claimed in claim 1, wherein there is further included a step of using CDMA 2000 protocol by the first and second networks.

9. The method for network controlled call forwarding as claimed in claim 1, wherein the step of returning an error message includes the step of returning the error message by the first and second network for an error in the second network.

10. The method for network controlled call forwarding as claimed in claim 1, wherein the step of returning an error message includes the step of returning the error message by the second network for an error in the second network.

11. The method for network controlled call forwarding as claimed in claim 1, wherein the step of returning the error message includes the step of returning the error message by the second network if the second subscriber is not reachable.

12. A method for network controlled call forwarding comprising the steps of:

placing a call by a first subscriber in a first network to a second subscriber in a second network;

indicating that the second network is unable to connect to the second subscriber; and

forwarding the call from the first subscriber to a voicemail system.

13. The method for network controlled call forwarding as claimed in claim 12, wherein there is further included steps of:

using session initiation protocol; and

the first and second networks are mobile internet protocol networks.

14. The method for network controlled call forwarding as claimed in claim 12, wherein there is further included a step of using by the first and second networks signaling system seven protocol.

15. The method for network controlled call forwarding as claimed in claim 12, wherein there is further included a step of using UMTS protocol by the first and second networks.

16. The method for network controlled call forwarding as claimed in claim 12, wherein there is further included a step of using CDMA 2000 protocol by the first and second networks.

17. A method for network controlled call forwarding comprising the steps of:

placing a call by a first subscriber in a first network to a second subscriber in a second network;

indicating that the second network is unable to connect to the second subscriber; and

responsive to the indicating step, forwarding the call from the first subscriber to a third subscriber.

18. The method for network controlled call forwarding as claimed in claim 17, wherein there is further included a step of using by the first and second networks signaling system seven protocol.

19. The method for network controlled call forwarding as claimed in claim 17, wherein there is further included a step of using UMTS protocol by the first and second networks.

20. The method for network controlled call forwarding as claimed in claim 17, wherein there is further included a step of using CDMA 2000 protocol by the first and second networks.
