Abstract

Methods, systems, and computer program products for enabling short code dialing in an ENUM environment are provided. According to one method, an ENUM query message that includes a calling party identifier and a called party short code identifier is received. An ENUM translation is performed to locate at least one URI corresponding to the calling party identifier and the called party short code identifier. The ENUM query message is responded to with the at least one URI.

Claims

1. A method for enabling ENUM service for communications directed to a called party short code identifier, the method comprising:

(a) receiving an ENUM query message that includes a calling party identifier and a called party short code identifier;

(b) performing an ENUM translation to locate least one URI corresponding to the calling party identifier and the called party short code identifier; and

(c) responding to the ENUM query message with the at least one URI.

2. The method of claim 1 comprising translating the calling party identifier and the called party short code identifier into an E.164 formatted called party number and wherein performing the ENUM translation includes performing the ENUM translation using the E.164 formatted called party identifier.

3. The method of claim 2 wherein translating the calling party identifier and the called party short code identifier into an E.164 formatted called party identifier includes using the calling party identifier and the called party short code identifier tuple to perform a lookup in a short code resolution database.

4. The method of claim 2 wherein performing the ENUM translation using the E.164 formatted called party identifier includes modifying the ENUM query message to include the E.164 formatted called party identifier.

5. The method of claim 4 wherein performing the ENUM translation includes transmitting the modified ENUM query message to an ENUM database.

6. The method of claim 2 wherein performing the ENUM translation using the E.164 formatted called party number includes generating a new ENUM query message that includes at least a portion of the received ENUM query message and the E.164 formatted called party identifier.

7. The method of claim 1 wherein performing the ENUM translation includes performing a lookup in an ENUM database using the calling party identifier and called party short code identifier as lookup keys.

8. A system for enabling ENUM service for communications directed to a called party short code identifier, the system comprising:

(a) a communications interface for receiving an ENUM query that includes a calling party identifier and a called party short code identifier;

(b) a short code resolution database for mapping the calling party identifier and the called party short code identifier to an E.164 formatted called party identifier; and

(c) a short code resolution function for;

(i) receiving the ENUM query from the communications interface;

(ii) for accessing the short code resolution database using the calling party identifier and called party short code identifier tuple and obtaining an associated E.164 formatted called party identifier; and

(iii) querying an ENUM database using the E.164 formatted called party identifier.

9. The system of claim 8 wherein the communication interface comprises an Internet protocol interface.

10. The system of claim 8 where the short code resolution database is co-located with the short code resolution function.

11. The system of claim 8 wherein the short code resolution function is adapted to modify the ENUM query to include the E.164 formatted called party number and to transmit the modified ENUM query to the ENUM database.

12. The system of claim 8 wherein the short code resolution function is adapted to terminate the received ENUM query and to formulate a new ENUM query including the E.164 formatted called party number.

13. The system of claim 8 wherein the short code resolution function is adapted to query an externally located short code resolution database.

14. A system for enabling ENUM service for communications directed to a called party short code identifier, the system comprising:

(a) means for receiving an ENUM query message that includes a calling party identifier and a called party short code identifier;

(b) means for performing an ENUM translation to locate least one URI corresponding to the calling party identifier and the called party short code identifier; and

(c) means for responding to the ENUM query message with the at least one URI.

15. The system of claim 14 wherein the means for receiving comprises a communications interface in a signaling node.

16. The system of claim 15 wherein the signaling node comprises one of a signal transfer point, a SIP signaling router, an ENUM server, and IMS node.

17. The system of claim 14 wherein the means for performing comprises a short code resolution function for translating the calling party identifier and the called party short code identifier into an E.164 formatted called party identifier and an ENUM translation function for translating the E.164 formatted called party identifier into the at least one URI.

18. The system of claim 14 wherein the means for performing comprises an ENUM translation function for accessing an ENUM database using the calling party identifier and the called party short code identifier as lookup keys.

19. A computer readable medium having stored thereon a short code-adapted ENUM database being accessible by an ENUM translation function to translate short code and calling party identifier combinations into URIs, the computer readable medium comprising:

(a) a memory, wherein the memory includes a short code adapted ENUM translation database accessible by an ENUM translation function to translate calling party identifier-called party short code combinations into URIs;

(b) wherein the short-code adapted ENUM translation database includes a plurality of entries, each entry including;

(i) a calling party identifier field;

(ii) a called party short code field; and

(iii) a uniform resource identifier field; and

(c) wherein the calling party identifier and called party short code fields are accessible by the ENUM translation function as indices to locate URIs corresponding to a short code-calling party identifier combination.

20. The computer-readable medium of claim 19 wherein each entry in the database includes an E.164 formatted called party field.
