Abstract

The invention relates to a method in a wireless communications system (WCS) of controlling charging procedures for message services which enable transport of messages from a mobile station (MS) to a service center (SC), the method comprising transporting a message from the mobile station (MS) for example via a network node (MSC/VLR) to the service center (SC), temporarily storing the message at the service center (40), sending a first confirmation acknowledging receipt of the message at a service center (SC) to the mobile station (MS), and, if the mobile station (MS) acknowledges receipt of the first confirmation, routing the message from the service center (SC) to a recipient of the message and initiating a charging procedure (CU) for a message. The invention also relates to a network node (MSC/VLR) implementing this method and a wireless communications system (WSC) comprising such a network node (MSC/VLR).

Claims

1. A method in a wireless communications system (WCS) of controlling charging procedures for message services which enable transport of messages from a mobile station (MS) to a service center (SC), said method comprising the steps of:

(a) transporting a message from the mobile station (MS) to the service center (SC);

(b) temporarily storing the message at the service center (SC);

(c) sending a first confirmation acknowledging receipt of the message at the service center (SC) to the mobile station (MS);

(d) determining, by said service center (SC), if the mobile station (MS) acknowledges receipt of the first confirmation, and, if the mobile station (MS) acknowledges receipt of the first confirmation, routing the message from the service center (SC) to a recipient of the message and initiating a charging procedure for the message.

2. The method of claim 1, wherein the message is transported from the mobile station (MS) to the service center (SC) via a network node (MSC/VLR).

3. The method of claim 1, wherein if the service center (SC) does not receive any instructions to the contrary, the service center (SC) routes the message to the recipient of the message after expiry of a first time interval.

4. The method of claim 3, wherein the first time interval is measured at at least one of the service center (SC) and a network node (MSC/VLR).

5. The method of claim 1, wherein, if the mobile station (MS) does not acknowledge receipt of the first confirmation, the message temporarily stored at the service center (SC) is deleted.

6. The method of claim 5, wherein the message temporarily stored at the service center (SC) is automatically deleted if the mobile station (MS) does not acknowledge receipt of the first confirmation during a second time interval.

7. The method of claim 6, wherein the second time interval is shorter than the first time interval.

8. The method of claim 6, wherein the second time interval is measured at a network node (MSC/VLR).

9. The method of claim 8, wherein, if the mobile station (MS) does not acknowledge receipt of the first confirmation during the second time interval, the network node (MSC/VLR) sends an instruction to the service center (SC), the instruction indicating that the mobile station (MS) has not acknowledged receipt of the first confirmation.

10. The method of claim 9, wherein the service center (SC) deletes the temporarily stored message upon receipt of the instruction.

11. The method of claim 1, wherein step (d) comprises sending a second confirmation acknowledging receipt of the first confirmation at the mobile station (MS) to at least one of the network node (MSC/VLR) and the service center (SC).

12. The method of claim 11, wherein step (d) comprises sending an instruction from the network node(MSC/VLR) to the service center (SC) upon receipt of the second confirmation, the instruction indicating that the mobile station (MS) has acknowledged receipt of the first confirmation.

13. The method of claim 2, wherein step (d) comprises sending an instruction from the network node (MSC/VLR) to the service center (SC), the instruction indicating whether or not the mobile station (MS) has acknowledged receipt of the first confirmation.

14. The method of claim 9, further comprising sending a third confirmation from the service center (SC) to the network node (MSC/VLR), the third confirmation acknowledging that the service center (SC) has acted upon the instruction.

15. The method of claim 3, wherein, if the mobile station (MS) has acknowledged receipt of the first confirmation, the charging procedure is initiated upon receipt of the third confirmation at a network node (MSC/VLR) or upon expiry of the first time interval.

16. The method of claim 9, wherein the instruction is a MAP message.

17. The method of claim 1, wherein the message is routed from the service center (SC) to the recipient of the message in dependence on an evaluation of statistical data associated with the mobile station (MS) from which the message has been sent.

18. A network node (MSC/VLR) in a wireless communications system (WCS) implementing message services which enable transport of messages from a mobile station (MS) to a service center (SC), the network node (MSC/VLR) comprising:

a router (20) for routing a message from the mobile station (MS) to the service center (SC) to be stored at the service center (SC), and for routing a first confirmation acknowledging receipt of the message at the service center (SC) to the mobile station (MS); and

a controller (30) for determining if the mobile station (MS) acknowledges receipt of the first confirmation, and for initiating a charging procedure for the message, if the mobile station (MS) acknowledges receipt of the first confirmation.

19. The network node of claim 18, further comprising a first timer (60) for measuring a first time interval, wherein, if the mobile station has not acknowledged receipt of the first confirmation during the first time interval, the controller (30) instructs the service center (SC) to delete the message.

20. A wireless communications system implementing message services which enable transport of messages from a mobile station (MS) to a service center (SC), the wireless communications system (WCS) comprising:

a network node (MSC/VLR) including a router (20) for routing a message from the mobile station (MS) to the service center (SC) to be stored at the service center (SC), and for routing a first confirmation acknowledging receipt of the message at the service center (SC) to the mobile station (MS), and a controller (30) for determining if the mobile station (MS) acknowledges receipt of the first confirmation, and for initiating a charging procedure for the message, if the mobile station (MS) acknowledges receipt of the first confirmation;

a gateway (SMS-IWMSC), the network node (MSC/VLR) communicating with the service center (SC) via the gateway (SMS-IWMSC).

21. The wireless communications system of claim 20, further comprising a charging unit (CU) for performing a charging procedure for each message routed from the service center (SC) to the recipient of the message.
