Abstract

Methods, apparatuses, system and a computer program product provide improved delivery of short messages. The method includes the steps of receiving a message to be delivered to user equipment, negotiating a timer value with a short message service routing element, forwarding the short message to the short message service routing element together with the negotiated timer value and starting a timer according to the negotiated timer value.

Claims

1. A method, which comprises the steps of:

receiving a message to be delivered to user equipment;

negotiating a timer value with a short message service routing element;

forwarding the message to the short message service routing element; and

starting a timer according to the timer value negotiated.

2. The method according to claim 1, which further comprises forwarding the timer value negotiated to the short message service routing element together with the message.

3. The method according to claim 1, wherein the negotiating step further comprises:

sending a request for a timer value proposal to the short message service routing element;

receiving a response including the timer value proposal from the short message service routing element; and

deciding the timer value based on the timer value proposal.

4. The method according to claim 3, wherein the deciding step further comprises forming the timer value according to the timer value proposal.

5. The method according to claim 3, wherein the deciding step further comprises forming the timer value to be smaller than the timer value proposal.

6. The method according to claim 3, wherein the request for the timer value proposal further includes an indication for support of a timer value re-negotiation mechanism.

7. The method according to claim 3, further comprising:

receiving a request for timer value re-negotiation from the short message service routing element; and

sending a response acknowledging the timer value re-negotiation to the short message service routing element.

8. The method according to claim 7, wherein the timer value re-negotiation includes restarting the timer.

9. The method according to claim 7, which further comprises:

deciding a second timer value; and

restarting the timer with the second timer value;

including in the response acknowledging the timer value re-negotiation, the second timer value.

10. A method, which comprises the steps of:

receiving a request for a timer value proposal from a short message service gateway element;

deriving a timer value proposal; and

sending a response including the timer value proposal to the short message service gateway element.

11. The method according to claim 10, wherein the deriving step is based on a number and sort of available delivery routes.

12. The method according to claim 10, wherein the request for the timer value proposal further includes an indication for support of a timer value re-negotiation mechanism, the method further comprises:

sending a request for a timer value re-negotiation to the short message service gateway element; and

receiving a response acknowledging the timer value re-negotiation from the short message service gateway element.

13. The method according to claim 12, wherein the timer value re-negotiation includes restarting a timer.

14. The method according to claim 12, wherein the request for the timer value re-negotiation further comprises a second proposed timer value.

15. A short message service gateway element, comprising:

a receiver configured to receive a message to be delivered to user equipment;

a processor configured to negotiate a timer value with a short message service routing element and to start a timer according to the timer value negotiated; and

a transmitter for forwarding the message to the short message service routing element.

16. The short message service gateway element according to claim 15, wherein:

said transmitter configured to send a request for a timer value proposal to the short message service routing element;

said receiver configured to receive a response including the timer value proposal from the short message service routing element; and

said processor configured to decide the timer value based on the timer value proposal received.

17. The short message service gateway element according to claim 15, wherein the timer value negotiated is forwarded to the short message service routing element together with the message.

18. The short message service gateway element according to claim 16, wherein said processor configured to determine the timer value according to the timer value proposal.

19. The short message service gateway element according to claim 16, wherein said processor configured to form the timer value to be smaller than the timer value proposal.

20. The short message service gateway element according to claim 16, wherein the request for the timer value proposal further includes an indication for support of a timer value re-negotiation mechanism.

21. The short message service gateway element according to claim 15, wherein:

said receiver configured to receive a request for a timer value re-negotiation from the short message service routing element; and

said transmitter configured to send a response acknowledging the timer value re-negotiation to the short message service routing element.

22. The short message service gateway element according to claim 21, wherein the timer value re-negotiation includes restarting the timer.

23. The short message service gateway element according to claim 21, wherein:

said processor configured to form a second timer value and to restart the timer with the second timer value; and

said response acknowledging the timer value re-negotiation further comprises the second timer value.

24. A short message service routing element, comprising:

a receiver configured to receive a request for a timer value proposal from a short message service gateway element;

a processor configured to derive a timer value proposal; and

a transmitter configured to send a response including the timer value proposal to the short message service gateway element.

25. The short message service routing element according to claim 24, wherein said processor configured to derive the timer value based on a number and sort of available delivery routes.

26. The short message service routing element according to claim 24, wherein:

said transmitter configured to send a request for a timer value re-negotiation to the short message service gateway element; and

said receiver configured to receive a response acknowledging timer value re-negotiation from the short message service gateway element.

27. The short message service routing element according to claim 26, wherein the timer value re-negotiation includes restarting a timer.

28. The short message service routing element according to claim 26, wherein the request for the timer value re-negotiation further includes a second proposed timer value.

29. The short message service routing element according to claim 28, wherein the response acknowledging the timer value re-negotiation further includes the second proposed timer value.

30. A computer-readable medium having computer-executable instructions configured to control a processor to perform a method which comprises the steps of:

receiving a message to be delivered to user equipment;

negotiating a timer value with a short message service routing element;

forwarding the message to the short message service routing element; and

starting a timer according to the timer value negotiated.

31. A computer-readable medium having computer-executable instructions configured to control a processor to perform a method which comprises the steps of:

receiving a request for a timer value proposal from a short message service gateway element;

deriving a timer value proposal; and

sending a response including the timer value proposal to a short message service gateway element.
