Abstract

A system for transmitting short messages between mobile communication systems includes a first mobile communication system which is based on a first mobile communication standard, a first short message service center connected to the first mobile communication system, a second mobile communication system based on a second mobile communication standard, a second short message service center connected to the second mobile communication system, a home location register connected to the second mobile communication system, a mobile services switching center connected to the second mobile communication system, and a gateway for communications with and between the first and second mobile communication system. In a method implementing this functionality a routing component sends to the gateway a routing data query addressed to a predetermined numerical space. The short message is transmitted to the gateway, based on the address received in response to the routing data query, for further transmission of the short message to the second mobile communication system.

Claims

1. A gateway for communicating short messages between a first mobile communication system and a second mobile communication system, comprising:

a query returner configured to return an address of the gateway in response to a routing data query received from a first short message service center of the first mobile communication system, the routing data query associated with a short message to be routed to a subscriber of the second mobile communications system; and

a transformer configured to transform the short message from a first communication standard of the first mobile communication system to a second communication standard of the second mobile communication system for subsequent transmission of the short message to the subscriber of the second mobile communication system.

2. The gateway of claim 1, wherein the transformer is further configured to transform a short message acknowledgement received from a short message service center of the second mobile communication system in response to the transmitted short message from the second communication standard to the first communication standard, and wherein the gateway is configured to send the short message acknowledgement to the first short message service center of the first mobile communication system.

3. The gateway of claim 1, wherein the transformer is further configured to transform the routing data query from the first communication standard of the first mobile communication system to the second communication standard of the second mobile communication system for transmission of the routing data query to a home location register of the second mobile communication system, and further configured to transform an address of a mobile services switching center associated with the subscriber of the second mobile communication system received from the home location register in response to the routing data query, and wherein the address of the mobile services switching center is appended to the address of the gateway in the response to a routing data query.

4. The gateway of claim 3, wherein the transformer is further configured to transform a short message acknowledgement received from a mobile services switching center of the second mobile communication system in response to the transmitted short message from the second communication standard to the first communication standard, and wherein the gateway is configured to send the short message acknowledgement to the first short message service center of the first mobile communication system.

5. The gateway of claim 1, further comprising a temporary database configured to maintain information related to short messaging transactions.

6. The gateway of claim 1, wherein the transformer is further configured to transform the short message from a Mobile-Terminating format to a Mobile-Originating format.

7. A method for communicating messages between a first mobile communication system and a second mobile communication system, comprising:

receiving at a gateway a routing data query conforming to a first mobile communication standard from a first short message service center located within the first mobile communication system;

returning an address of the gateway in a response message in response to the routing data query received from the first short message service center;

receiving a short message directed to a predetermined numerical address space from the first short message service center;

transforming at the gateway the short message received from the first short message service center from the first mobile communication standard to a second mobile communication standard; and

directing the short message conforming to the second mobile communication standard to a service center located within the second mobile communication system.

8. The method of claim 7, wherein the service center of the second mobile communication system is a second short message service center.

9. The method of claim 7, wherein the service center of the second mobile communication system is a mobile services switching center.

10. The method of claim 7, further comprising transforming the routing data query to conform with the second mobile communication standard and directing the routing data query conforming with the second mobile communication standard to a home location register of the second mobile communication system.

11. The method of claim 10, further comprising receiving a response message including an address of a mobile services switching center from the home location register and transforming the address of the mobile services switching center received in the response from the home location register to conform to the first mobile communication standard.

12. The method of claim 11, further comprising appending the address of the mobile services switching center to the address of the gateway in the response message to the routing query.

13. The method of claim 7, further comprising transforming an acknowledgment received from the service center located within the second mobile communication system to conform to the first mobile communication standard.

14. The method of claim 7, further comprising maintaining information related to short messaging transactions.

15. The method of claim 7, further comprising transforming the short message from a Mobile-Terminating format to a Mobile-Originating format.

16. A gateway for communicating short messages between a first mobile communication system and a second mobile communication system, comprising:

means for returning an address of the gateway in response to a routing data query received from a first short message service center of the first mobile communication system, the routing data query associated with a short message to be routed to a subscriber of the second mobile communications system; and

means for transforming the short message from a first communication standard of the first mobile communication system to a second communication standard of the second mobile communication system for subsequent transmission of the short message to the subscriber of the second mobile communication system.

17. The gateway of claim 16, wherein the means for transforming is further configured to:

transform the routing data query from the first communication standard of the first mobile communication system to the second communication standard of the second mobile communication system for transmission of the routing data query to a home location register of the second mobile communication system, and further configured to transform an address of a mobile services switching center associated with the subscriber of the second mobile communication system received from the home location register.
