Message waiting notification to external message centers
View Patent ↗Systems and methods are disclosed for notifying external message centers when a mobile device becomes available to receive a text message. One embodiment includes a message waiting system that identifies a failed delivery attempt of a text message to a mobile device that is unavailable, where the text message originated from an external message center. The system identifies routing information for the external message center based on the failed delivery attempt, generates a Message Waiting Indicator (MWI) record for the text message that includes the routing information for the external message center, and stores the MWI record. When the system identifies that the mobile device becomes available, the system identifies the MWI record that includes information on the failed delivery attempt to the mobile device, and sends a notification indicating that the mobile device is available to the external message center based on the routing information in the MWI record.
1. A message waiting system comprising:
a control system operable to identify a failed delivery attempt of a text message to a mobile device that is unavailable, where the text message originated from an external message center that sent the text message directly to the mobile device without going through a home message center of the mobile device;
wherein the control system is further operable to identify routing information for the external message center based on the failed delivery attempt,
to identify when the mobile device becomes available, and to send a notification indicating that the mobile device is available to the external message center based on the routing information to allow the external message center to retry delivery of the text message to the mobile device.
2. The message waiting system of claim 1 wherein:
the control system is further operable to identify a signaling protocol used by the external message center, to store an indication of the signaling protocol, and to send the notification to the external message center based on the signaling protocol.
3. The message waiting system of claim 2 wherein:
the control system is further operable to identify the signaling protocol used by the external message center based on the failed delivery attempt.
4. The message waiting system of claim 1 wherein:
the control system is further operable to store a mobile identifier for the mobile device.
5. The message waiting system of claim 1 wherein:
the control system is further operable to delete the routing information for the external message center after the notification is received by the external message center.
6. The message waiting system of claim 1 wherein the routing information for the external message center comprises a point code.
7. The message waiting system of claim 1 wherein the routing information for the external message center comprises an Internet Protocol (IP) address.
8. A method comprising:
identifying a failed delivery attempt of a text message to a mobile device that is unavailable, where the text message originated from an external message center that sent the text message directly to the mobile device without going through a home message center of the mobile device;
identifying routing information for the external message center based on the failed delivery attempt;
identifying when the mobile device becomes available; and
sending a notification indicating that the mobile device is available to the external message center based on the routing information to allow the external message center to retry delivery of the text message to the mobile device.
9. The method of claim 8 further comprising:
identifying a signaling protocol used by the external message center;
storing an indication of the signaling protocol; and
sending the notification to the external message center based on the signaling protocol.
10. The method of claim 9 wherein identifying a signaling protocol used by the external message center comprises:
identifying the signaling protocol used by the external message center based on the failed delivery attempt.
11. The method of claim 8 further comprising:
storing a mobile identifier for the mobile device.
12. The method of claim 8 further comprising:
deleting the routing information for the external message center after the notification is received by the external message center.
13. The method of claim 8 wherein the routing information for the external message center comprises a point code.
14. The method of claim 8 wherein the routing information for the external message center comprises an Internet Protocol (IP) address.
15. An apparatus comprising:
a network element operable to serve a mobile device, wherein the network element includes a control system operable to identify a failed delivery attempt of a text message to the mobile device that is unavailable, wherein the text message originated from an external message center that sent the text message directly to the mobile device without going through a home message center of the mobile device;
wherein the control system is further operable to identify when the mobile device becomes available, and to send a notification indicating that the mobile device is available to the external message center to allow the external message center to retry delivery of the text message to the mobile device.
16. The apparatus of claim 15 wherein:
the control system is further operable to identify routing information for the external message center based on the failed delivery attempt, to generate a message waiting indicator (MWI) record for the text message that includes the routing information for the external message center, and to store the MWI record in a storage system;
the control system is further operable to identify when the mobile device becomes available, to identify the MWI record in the storage system that includes information on the failed delivery attempt by the external message center, and to send the notification indicating that the mobile device is available to the external message center based on the routing information in the MWI record.
17. The apparatus of claim 16 wherein:
the control system is further operable to identify a signaling protocol used by the external message center, to store an indication of the signaling protocol in the MWI record, and to send the notification to the external message center based on the signaling protocol indicated in the MWI record.
18. The apparatus of claim 16 wherein:
the control system is further operable to delete the MWI record after the notification is received by the external message center.
19. The apparatus of claim 16 wherein the routing information for the external message center comprises a point code.
20. The apparatus of claim 15 wherein:
the control system is further operable to identify a failed delivery attempt of a text message to the mobile device from a store-and-forward (SFD) system within the home message center, wherein the home message center further includes a First Delivery Attempt (FDA) system;
the control system is further operable to identify routing information for the SFD system based on the failed delivery attempt, to generate a message waiting indicator (MWI) record that includes the routing information for the SFD system, and to store the MWI record in a storage system;
the control system is further operable to identify when the mobile device becomes available, to identify the MWI record in the storage system that includes information on the failed delivery attempt by the SFD system, and to send another notification indicating that the mobile device is available to the SFD system based on the routing information in the MWI record.
