Abstract

A system for routing SMS-messages to a plurality of short message service centers, comprising:a first transceiver for sending and receiving SMS-messages over a fixed network; a router table for identifying from a recipient address of a SMS-message a short message service center that services the intended recipient of the SMS-message, said first transceiver cooperating with the router table in order to submit a received SMS-message to an identified short message service center servicing the intended recipient. The system further comprises a GSM-node comprising a second transceiver for sending and receiving SMS-messages to and from a GSM-network, said second transceiver connected to said first transceiver; wherein said first transceiver and said GSM-node are connected and wherein said first transceiver is adapted to submit a SMS-message to said GSM-node when the short message is of a predetermined format, so that the GSM-node forms a proxy connected to the GSM-network.

Claims

1. A system for routing SMS-messages to a plurality of short message service centers, the system comprising:

a first transceiver for sending and receiving SMS-messages over a fixed network;

a router table for identifying from a recipient address of a SMS-message a short message service center that services the intended recipient of the SMS-message, said first transceiver cooperating with the router table in order to submit a received SMS-message to an identified short message service center servicing the intended recipient; and

a GSM-node comprising a second transceiver for sending and receiving SMS-messages to and from a GSM-network, said second transceiver connected to said first transceiver;

wherein said first transceiver is adapted to submit a SMS-message to said GSM-node when the short message is of a predetermined format, so that the GSM-node forms a proxy connected to the GSM-network.

2. A system according to claim 1, wherein said GSM-node further comprises:

a first receiver for receiving from a GSM-network a request for routing information for routing a SMS-message via said GSM-network to the GSM-node; and

a first transmitter for transmitting said routing information to the GSM-network in order to receive said SMS-message.

3. A system according to claim 1, wherein said first transceiver and said GSM-node are connected via a wide area network.

4. A system according to claim 3, wherein said wide area network comprises a trans-atlantic high-speed data link.

5. A router comprising:

a first transceiver for sending and receiving SMS-messages over a fixed network;

a router table for identifying from a recipient address of a SMS-message a short message service center that services the intended recipient of the SMS-message, said first transceiver cooperating with the router table in order to submit a received SMS-message to an identified short message service center servicing the intended recipient;

wherein said first transceiver is adapted to send and receive SMS-messages to and from a GSM-node that is to be connected to said first transceiver, the GSM-node comprising a second transceiver for sending and receiving SMS-messages to and from a GSM-network, wherein said first transceiver is adapted to submit a SMS-message to said GSM-node when the SMS-message is of a predetermined format, so that the GSM-node forms a proxy connected to the GSM-network.

6. A router according to claim 5, wherein said first transceiver is adapted to be connected to said GSM-node via a wide area network.

7. A router according to claim 6, wherein said wide area network comprises a trans-atlantic high-speed data link.

12. A GSM-node comprising:

a first receiver for receiving from a GSM-network a request for routing information for routing a SMS-message via said GSM-network to the GSM-node;

a first transmitter for transmitting routing information to the GSM-network in order to receive said SMS-message;

a second receiver for receiving said SMS-message from said GSM-network;

a second transmitter adapted to send a received SMS-message from said GSM-network to a router according to claim 5 or to a short message service center according to claim 8;

and

a gateway for relaying SMS-messages received from a router according to claim 5 or a short message service center according to claim 8 to the GSM-network.

13. A GSM-node according to claim 12, wherein said second transmitter is adapted to send a received SMS-message via a wide area network.

14. A GSM-node according to claim 13, wherein said wide area network comprises a trans-atlantic high-speed data link.

15. A short message service centre for sending a short message (SMS-message), wherein a recipient address of the destined recipient is specified by the SMS-message;

the SMSC comprising a router for identifying from said recipient address a mobile switching centre that services the intended recipient of the SMS-message, said router adapted to route the short message to a GSM-node of a system as claimed in claim 12 if said recipient address is of a predetermined format.

16. Method of routing a SMS-message to a recipient address, the method comprising the steps of:

identifying the recipient address;

routing, if the recipient address is of a predetermined format to a GSM-node of a system as claimed in claim 12.

17. Method of routing a SMS-message to a recipient address, the method comprising the steps of:

receiving a SMS-message from a GSM-node as claimed in claim 12;

providing a connection between said GSM-node and a router as claimed in claim 5.

relaying said SMS-message to said router; and

routing said message via said router to said recipient address.

18. Method of routing a SMS-message to a recipient address, the method comprising the steps of:

receiving a SMS-message in a router as claimed in claim 5;

providing a connection to a GSM-node as claimed in claim 12;

submitting said SMS-message to said GSM-node when the SMS-message is of a predetermined format, so that the GSM-node forms a proxy connected to the GSM-network;

delivering said message to the recipient address.

8. A short message service centre for receiving short messages and relaying short messages in a non-GSM radionetwork, such as a TDMA or a CDMA radionetwork, the service centre comprising:

a GSM-node comprising a transceiver for sending and receiving SMS-messages to and from a GSM-network;

wherein said short message service centre and said GSM-node are connected and wherein said short message service centre is adapted to submit a SMS-message to said GSM-node when the SMS-message is of a predetermined format, so that the GSM-node forms a proxy connected to the GSM-network.

9. A short message service centre according to claim 8, wherein the GSM-node further comprises:

a first receiver for receiving from a GSM-network a request for routing information for routing a SMS-message via said GSM-network to the GSM-node; and

a first transmitter for transmitting routing information to the GSM-network in order to receive said SMS-message.

10. A short message service centre according to claim 8, wherein said short message service centre and said GSM-node are connected via a wide area network.

11. A short message service centre according to claim 9, wherein said wide area network comprises a trans-atlantic high-speed data link.
