Abstract

Efficient routing of a message over a data network. A first communication device sends a message to a telemetry gateway or short message arbitrator. The telemetry gateway or short message arbitrator determines the communication protocol of the first communication device and the communication protocol of a second communication device. The telemetry gateway or short message arbitrator converts the message to a data format compatible with the second communication device, wherein the message is converted to one of at least three different communication protocols. The telemetry gateway or short message arbitrator then forwards the message for receipt by the second communication device. The telemetry gateway or short message arbitrator can convert and forward the message without completing a store and forward process.

Claims

1. A communication method, comprising the steps of:

receiving a message, comprising data content and an identifier, at a telemetry gateway;

responsive to determining the identifier at the telemetry gateway, retrieving a profile from a database;

converting the message at the telemetry gateway from a first format to one of at least three different formats based on the retrieved profile, such that the data content of the message can be received by a recipient; and

responsive to conversion of the message, transmitting the converted message from the telemetry gateway to the recipient without completing a store and forward process.

2. The method of claim 1, further comprising the steps of:

receiving at the telemetry gateway a registration notification from a mobile switching center; and

sending from the telemetry gateway a registration response to the mobile switching center, the registration response comprising information concerning the recipient.

3. The method of claim 1, wherein the first format comprises one of CDMA, TDMA, and GSM.

4. The method of claim 1, wherein one of the at least three different formats comprises a format compatible with one of an email system, a voicemail system, or a web-based messaging system.

5. The method of claim 1, further comprising the step of sending an acknowledgment from the telemetry gateway to an originator of the message confirming that the message has been delivered to the recipient.

6. The method of claim 1, wherein the telemetry gateway receives the message from a signal transfer point.

7. The method of claim 1, wherein the message is an inbound message, and

wherein the method further comprises the steps of:

at the telemetry gateway, receiving from the recipient an outbound message having a format other than the first format; and

converting the outbound message to the first format for transmission from the telemetry gateway.

8. A method for routing a message using a telemetry gateway, comprising the steps of:

receiving at the telemetry gateway the message from a communication device;

requesting by the telemetry gateway routing information from a mobile switching center;

receiving at the telemetry gateway the routing information;

based on the routing information, converting the message at the telemetry gateway from a first format to one of at least three different formats; and

responsive to conversion of the message, transmitting the converted message from the telemetry gateway to the mobile switching center without completing a store and forward process.

9. The method of claim 8, further comprising the steps of:

when the mobile switching center does not have a database entry for the recipient, receiving at the telemetry gateway a qualification request from the mobile switching center; and

sending by the telemetry gateway a qualification response to the mobile switching center.

10. The method of claim 8, further comprising the step of sending an acknowledgement from the telemetry gateway to the communication device confirming delivery of the message to the recipient.

11. The method of claim 8, wherein the step of based on the routing information, converting the message at the telemetry gateway from a first format to one of at least three different formats comprises the steps of:

retrieving a profile from a database; and

selecting the one of at least three different formats from the at least three different formats according to the profile.

12. A telemetry gateway, coupled to a data source, having a software module stored in a memory storage device, the software module comprising computer-readable instructions that, when executed, implement the steps of:

determining an identifying characteristic and a destination of a message received from a first communication device based on data contained within the message;

retrieving a profile from a database according to the determined identifying characteristic;

converting the message from a first format to one of at least three different formats according to the retrieved profile; and

forwarding the converted message for delivery to a second communication device without completing a store and forward process.

13. The telemetry gateway of claim 12, wherein the telemetry gateway is further connected to a SS7 data inter-networking system.

14. The telemetry gateway of claim 13, wherein the message is forwarded from the telemetry gateway to the second communication device using the SS7 data inter-networking system.

15. The telemetry gateway of claim 12, wherein the message passes through a mobile switching center before being received by the telemetry gateway.

16. The telemetry gateway of claim 12, wherein the software module is further configured to:

send a route request to a mobile switching center; and

receive route information from the mobile switching center.

17. The telemetry gateway of claim 12, wherein the software module is further configured to:

receive a registration notification from a mobile switching center;

send a registration response to the mobile switching center, wherein the registration response contains account and service information related to one of the communication devices.

18. The telemetry gateway of claim 12, wherein the first format is converted from a wireless access format to a format compatible with one of an email system, a voicemail system, or a web-based messaging system.

19. The telemetry gateway of claim 12, wherein the first format is converted from a format compatible with one of an email system, a voicemail system, or a web-based messaging system to a wireless access format.

20. A method for routing a message between a first device and a second device, comprising the steps of:

receiving a message, comprising an identifier and having a first data format, at a short message arbitrator;

responsive to determining the identifier of the message, accessing a database at the short message arbitrator to retrieve a profile for the first device and the second device;

based on the retrieved profile, analyzing at the short message arbitrator whether the first device and second device communicate using incompatible data formats; and

converting the message at the short message arbitrator from the first format to one of at least three different data formats according to the retrieved profile; and

forwarding the message by the short message arbitrator in the converted format for receipt by the second device.

21. The method of claim 20, wherein the step of analyzing whether the first device and second device communicate using incompatible data formats comprises:

determining a mobile switching center for the second device;

determining a class of service for the first device;

determining a class of service for the second device; and

determining a type of transport to use between the short message arbitrator and the second device.

22. The method of claim 21, wherein the class of service for the first device comprises at least one of short message system;

asynchronous digital data; and

data over circuit switched voice cellular.

23. The method of claim 21, wherein the mobile switching center is determined based on a mobile identification number associated with the second device.

24. The method of claim 21, wherein the short message arbitrator forwards the message for receipt by the second device based on the determined type of transport to use between the short message arbitrator and the second device.

25. The method of claim 20, further comprising the steps of:

receiving a second message from the second device at a telemetry gateway that comprises the short message arbitrator;

at the telemetry gateway, reformatting the second message for receipt by the first device; and

forwarding the reformatted second message from the telemetry gateway to the first device.
