Abstract

Methods and systems for triggerless screening of WMS messages for delivery with differential quality of service (QoS) are disclosed. Signaling messages are screened to determine whether they contain WMS content. In response to determining that a message contains WMS content, origination and/or destination party information is extracted from the WMS message to determine the QoS associated with the WMS message. The WMS message is then modified to include routing information for delivering the SMS messages to their intended destinations with different qualities of service.

1. A method for routing wireless message service (WMS) signaling messages in a communications network with a desired quality of service (QoS), the method comprising:

(a) receiving a WMS signaling message including mobile subscriber originating and destination party identification information and WMS content;

(b) determining, based on at least one of the originating and destination party identification information, a QoS associated with the signaling message; and

(c) routing the signaling message to a destination through a signaling network with the indicated QoS.

2. The method of claim 1 wherein receiving a WMS signaling message includes receiving a WMS signaling message at a signal transfer point.

3. The method of claim 2 wherein receiving a WMS signaling message at a signal transfer point includes receiving a WMS signaling message addressed to the signal transfer point.

4. The method of claim 2 wherein receiving a WMS signaling message at a signal transfer point include intercepting, at the signal transfer point, a WMS signaling addressed to a node other than the signal transfer point.

5. The method of claim 1 wherein receiving a WMS signaling message includes receiving a multimedia service (MMS) signaling message.

6. The method of claim 1 wherein receiving a WMS signaling message includes receiving an enhanced message service (EMS) message.

7. The method of claim 1 wherein the originating and destination party identification information includes mobile subscriber ISDN (MSISDN) numbers.

8. The method of claim 1 wherein the originating and destination party identification information includes international mobile station identifiers (IMSIs).

13. The method of claim 1 wherein determining the QoS includes selecting between multiple QoS levels for providing different WMS delivery speeds.

14. The method of claim 1 determining the QoS includes selecting between a first QoS level that guarantees WMS delivery within a predetermined time period and a second level that does not.

15. The method of claim 1 wherein determining the QoS includes selecting between a first QoS level that provides message delivery confirmation and a first message delivery priority and a second QoS level that does not provide message delivery confirmation and that provides a second message delivery priority lower than the first message delivery priority.

16. The method of claim 1 wherein determining the QoS includes selecting between an emergency QoS level and a non-emergency QoS level.

17. The method of claim 1 wherein determining the QoS includes determining the QoS based on information extracted from the IS-41 MAP SMS originating address of the message.

18. The method of claim 1 wherein determining the QoS includes determining the QoS based on information extracted from the IS-41 MAP destination address of the message.

19. The method of claim 1 wherein determining the QoS includes determining the QoS based on information extracted from the GSM MAP relay protocol origination address of the message.

20. The method of claim 1 wherein determining the QoS includes determining the QoS based on information extracted from the GSM MAP relay protocol destination address of the message.

21. The method of claim 1 wherein routing the signaling message to a destination with the indicated quality of service includes routing the message to a wireless message service center that provides the indicated quality of service.

22. The method of claim 1 wherein routing the signaling message to a destination with the indicated QoS includes routing the message over a route that provides the indicated QoS.

23. A system for routing wireless message service (WMS) signaling messages in a communications network with a desired quality of service (QoS), the system comprising:

(a) a communications module for sending and receiving WMS signaling messages, each message including a mobile subscriber identifier;

(b) a WMS quality of service identifier operatively associated with the communications module for determining, based on the mobile subscriber identifier associated with one of the WMS signaling messages, a QoS associated with the signaling message and for modifying the message to include muting information for providing the indicated QoS for the signaling message through the signaling network; and
