Abstract

A system, method and computer-readable medium for allowing the use of an alternative numbering plan for delivering short messages to mobile subscribers using the public mobile telephone network is provided. Users of an enterprise or other closed networks as well as users that are not part of a closed network may send short messages destined to members of an enterprise or closed network from their mobile or other devices associated with their subscription using an alternative enterprise directory number, such as the office number, instead of the mobile number, such that the alternative number will be presented at the destination device as the originating number. The recipient may respond to the message by addressing the response to the enterprise or closed network number, and the response may be delivered to the originator'"'"'s mobile or other device associated with their subscription.

Claims

1. A method, comprising:

reading, from an SMS message, an origination number associated with an originating device of a first user and a destination number associated with a destination device of a second user;

determining at least one of the first user and the second user is subscribed to an enterprise service;

replacing at least one of;

the origination number of the SMS message with an enterprise directory number assigned to the first user that is subscribed to the enterprise service, wherein the origination number is an MSISDN number;

the destination enterprise directory number of the SMS message with a MSISDN number assigned to the second user that is subscribed to the enterprise service; and

routing the SMS message with the MSISDN number as the destination number to the destination device.

2. The method of claim 1, wherein determining comprises determining the first user is subscribed to the enterprise service, the method comprising:

identifying the origination number as an MSISDN number allocated to a first mobile terminal assigned to the first user; and

determining the MSISDN number is associated with the enterprise directory number of the land-line enterprise telephony device, wherein replacing comprises replacing the origination number with the enterprise directory number.

3. The method of claim 2, comprising routing the SMS message with the enterprise directory number as the origination number to the destination device.

4. The method of claim 3, wherein determining at least one of the first user and the second user is subscribed to an enterprise service comprises determining the second user is subscribed to the enterprise service, the method comprising:

identifying the destination number as an enterprise directory number allocated to a second land-line enterprise telephony device assigned to the second user;

determining a second MSISDN number associated with the second user; and

replacing the destination number with the second MSISDN number.

5. The method of claim 1, wherein determining comprises determining the second user is subscribed to the enterprise service, the method comprising:

identifying the destination number as an enterprise directory number allocated to the land-line enterprise telephony device assigned to the second user; and

determining an MSISDN number is associated with the enterprise directory number of the land-line enterprise telephony device, wherein replacing comprises replacing the destination number with the MSISDN.

6. The method of claim 1, comprising:

receiving the SMS message at a mobile switching center (MSC);

retrieving, by the MSC, a profile associated with the first user from a visitor location register that includes SMS CAMEL subscription information;

invoking CAMEL service logic for mobile originated short message submissions based on trigger information included in the SMS CAMEL subscription information; and

forwarding, by the carrier gateway server, the SMS message to an enterprise gateway server based on the SMS CAMEL subscription information.

7. The method of claim 6, wherein determining at least one of the first user and the second user is subscribed to the enterprise is performed by the carrier gateway server.

8. The method of claim 6, comprising interrogating, by the enterprise gateway server, an enterprise member database with the origination number and the destination number.

9. The method of claim 8, comprising retrieving a record from the enterprise member database that associates the origination number with the land-line enterprise telephony device, wherein replacing at least one of the origination number and the destination number with an enterprise directory number of the land-line enterprise telephony device comprises replacing the origination number with the enterprise directory number.

10. The method of claim 6, wherein replacing at least one of the origination number and the destination number is performed by the enterprise gateway server.

11. The method of claim 1, comprising:

intercepting the SMS message by a router deployed in the network; and

evaluating, by the router, the origination number, wherein determining at least one of the first user and the second user is subscribed to an enterprise service is performed by the router; and

in response to determining the first user is subscribed to the enterprise server, forwarding the SMS message to a carrier gateway server adapted to identify the enterprise and forward the SMS message to an enterprise gateway server deployed by the enterprise.

12. The method of claim 1, comprising:

interrogating a home location register with the destination number, wherein the destination number comprises the enterprise directory number of the land-line enterprise telephony device assigned to the second user;

receiving a point code from the home location register, wherein the point code is assigned to a carrier gateway server; and

forwarding the SMS message to the carrier gateway server, wherein the carrier gateway server determines the second user is subscribed to the enterprise service.

13. A system, comprising:

a cellular network adapted to receive an SMS message from a mobile terminal addressed to a destination device;

a server adapted to read from the SMS message an origination number associated with the mobile terminal and a destination number associated with the destination device, wherein the server replaces at least one of;

the origination number of the SMS message with an enterprise directory number assigned to the first user that is subscribed to the enterprise service, wherein the origination number is an MSISDN number;

the destination enterprise directory number of the SMS message with a MSISDN number assigned to the second user that is subscribed to the enterprise service; and

routes the SMS message with the MSISDN number as the destination number to the destination device.

14. The system of claim 13, wherein the server determines the mobile terminal is allocated a one number service subscription, and wherein the server identifies the origination number as an MSISDN number allocated to the mobile terminal and determines the MSISDN number is associated with the enterprise directory number of the land-line enterprise telephony device, wherein the server replaces the origination number with the enterprise directory number.

15. The system of claim 14, wherein the server routes the SMS message with the enterprise directory number as the origination number to the destination device.

16. The system of claim 15, wherein the server determines the destination device is allocated a one number service subscription, wherein the server identifies the destination number as an enterprise directory number allocated to a second land-line enterprise telephony device associated with the destination device, determines a second MSISDN number associated with the second user, and replaces the destination number with the second MSISDN number.

17. The system of claim 13, wherein the server determines the second user has the one number service subscription, identifies the destination number as an enterprise directory number allocated to the land-line enterprise telephony device assigned to the second user, determines an MSISDN number is associated with the enterprise directory number of the land-line enterprise telephony device, and replaces the destination number with the MSISDN.

18. The system of claim 13, comprising a carrier gateway server deployed in the cellular network, wherein the cellular network includes a mobile switching center that receives the SMS message, wherein the mobile switching center is interfaced with a visitor location register that includes a profile that includes SMS CAMEL subscription information of the first user that is retrieved by the mobile switching center, wherein the mobile switching center invokes CAMEL service logic for mobile originated short message submissions based on trigger information included in the SMS CAMEL subscription information, and wherein the carrier gateway server forwards the SMS message to the server based on the SMS CAMEL subscription information.

19. The system of claim 18, wherein the server interrogates the enterprise member database with the origination number and the destination number.

20. The system of claim 19, wherein the server retrieves a record from the enterprise member database that associates the origination number with the land-line enterprise telephony device, wherein the server replaces the origination number with the enterprise directory number.

21. The system of claim 13, comprising:

a carrier gateway server deployed in the cellular network; and

a home location register having a record defining a profile allocated for the enterprise telephony device that includes a point code of the carrier gateway server assigned to a mobile switching center identifier field of the record.
