First Claim
1. A method for overriding a call forwarding service of a mobile device, the method comprising:
- transmitting a first send routing information message from a mobile switching center to a home location register, wherein the send routing information message requests routing information for the mobile device in response to a call to the mobile device;
processing at the mobile switching center a first send routing information acknowledgement message, wherein the first send routing information acknowledgment message is received from the home location register in response to the first send routing information message and includes location information of a call forwarding number of the mobile device;
determining at the mobile switching center, in response to the first send routing information acknowledgement message, that a call to the call forwarding number of the mobile device was not answered;
transmitting a second send routing information message from the mobile switching center to the home location register in response to determining that the call to the call forwarding number of the mobile device was not answered; and
processing at the mobile switching center a second send routing information acknowledgement message, wherein the second send routing information acknowledgement message is received from the home location register in response to the second send routing information message and includes location information of the mobile device.

Abstract
A method for overriding a call forwarding service of a mobile device enables enhanced call forwarding services. The method includes transmitting a first send routing information message from a mobile switching center to a home location register (step 305). The mobile switching center then processes a first send routing information acknowledgement message (step 310). The first send routing information acknowledgment message includes location information of a call forwarding number of the mobile device. The mobile switching center then determines that a call to the call forwarding number of the mobile device was not answered (step 315). A second send routing information message is then transmitted from the mobile switching center to the home location register (step 320). Finally, the mobile switching center processes a second send routing information acknowledgement message that includes location information of the mobile device (step 325).
