Patent Images
1. A method performed by a computing device, the method comprising:
- receiving, over a wireless data network from an originating mobile device, a short message service (SMS) message that includes a mobile directory number (MDN) of the originating mobile device;
conducting a lookup to determine a home short message service center (SMSC) for the originating mobile device based on the MDN;
sending a redirect message over the wireless data network to the originating mobile device if the computing device is not the home SMSC for the originating mobile device; and
providing services for the SMS message if the computing device is the home SMSC for the originating mobile device.

Abstract
A method for offloads SMS messages from a voice network of a wireless carrier to a data network. The method includes sending a mobile originated SMS using hypertext transfer protocol (HTTP) from a wireless handset to a short message service center (SMSC) over a wireless data network. The method further includes conducting a lookup at the SMSC to determine the home SMSC for the originating mobile handset and sending a redirect to the mobile handset as means to facilitate a dynamic update of the home SMSC location stored on the wireless handset.

9. A method performed by a mobile device, the method comprising:
-
formatting a short message service (SMS) message as a hypertext transfer protocol (HTTP) post, the HTTP post including a mobile directory number (MDN) of the mobile device; sending the HTTP post over a wireless data network to a default short message service center (SMSC) for the mobile device; receiving a confirmation from the default SMSC for the mobile device if the default SMSC determines, based on the MDN, that the default SMSC is also a home SMSC for the mobile device; and receiving one of a hostname of the home SMSC for the mobile device or an Internet Protocol (IP) address of the home SMSC for the mobile device if the default SMSC determines, based on the MDN, that the default SMSC is not the home SMSC for the mobile device. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A device, comprising:
-
a memory to store a short message service center (SMSC)/mobile directory number (MDN) lookup table; and a processor to; receive, over a wireless data network from a mobile device, a hypertext transfer protocol (HTTP) post that includes a short message service (SMS) message and a MDN of a mobile device; conduct a lookup in the SMSC/MDN lookup table to determine the home SMSC for the mobile device based on the MDN; send, over the wireless data network to the mobile device, one of a hostname of the home SMSC for the mobile device or an Internet Protocol (IP) address of the home SMSC for the mobile device if the device is not the home SMSC for the mobile device. - View Dependent Claims (17, 18, 19)
