Abstract

According to one aspect, the subject matter described herein comprises methods, systems, and computer program products for accessing number portability (NP) and E.164 number (ENUM) data in a combined NP/ENUM database. One method includes receiving a query including a telephone number (TN). A common NP/ENUM data locator structure is accessed to locate a pointer corresponding to the TN. In response to the query being a NP query, the pointer is used to locate NP data, and the NP data is returned. In response to the query being an ENUM query, the pointer is used to locate at least one URI and returning at least one uniform resource locators (URIs).

Claims

1. A method for accessing number portability (NP) and E.164 number (ENUM) data in a NP and ENUM database system, the method comprising:

(a) receiving a query including a telephone number (TN), wherein the query includes one of a NP query for requesting NP data and an ENUM query for requesting ENUM data;

(b) accessing a single NP and ENUM data locator structure to locate a pointer corresponding to the TN, wherein the single NP and ENUM data locator structure includes an index structure shared by the NP data and the ENUM data;

(c) in response to the query being a NP query, using the pointer to locate NP data, and returning the NP data; and

(d) in response to the query being an ENUM query, using the pointer to locate at least one uniform resource indicator (URI), and returning the at least one URI.

2. The method of claim 1 wherein accessing a single NP and ENUM data locator structure includes accessing a single NP and ENUM data locator structure located on the same hardware platform as the LNP and ENUM data.

3. The method of claim 1 wherein accessing a single NP and ENUM data locator structure includes accessing a single NP and ENUM data locator structure located on a different hardware platform from at least one of the LNP and ENUM data.

4. The method of claim 1 wherein accessing a single NP and ENUM data locator structure includes accessing a single NP and ENUM data locator structure located on a signal transfer point (STP).

5. The method of claim 1 wherein accessing a single NP and ENUM locator structure includes accessing a single NP and ENUM data locator structure located on a server.

6. The method of claim 1 wherein accessing a single NP and ENUM data locator structure includes accessing a single NP and ENUM data locator structure located on a service control point (SCP).

7. The method of claim 1 wherein accessing a single NP and ENUM data locator structure includes using the TN to traverse a plurality of tables corresponding to digits in the TN, wherein each of the tables corresponds to ranges of TN digits.

8. The method of claim 7 wherein accessing the plurality of tables includes determining whether ranges of digits in the TN correspond to ranges of TN digits for entries in each of the tables.

9. A number portability (NP) and E.164 number (ENUM) database system comprising:

(a) a single NP and ENUM data locator structure including a plurality of range tables linked using pointers, wherein one of the tables includes a pointer to data corresponding to the pointer, wherein the single NP and ENUM data locator structure includes an index structure shared by the NP data and the ENUM data; and

(b) an access engine for receiving a query, wherein the query includes one of a NP query for requesting NP data and an ENUM query for requesting ENUM data, for determining whether the query is an NP or an ENUM query, for accessing the single NP and ENUM data locator structure and locating a pointer corresponding to the TN in the query, for in response to the query being an NP query, using the pointer to access NP data to locate an LRN corresponding to the query, and, for, in response to the query being an ENUM query, using the pointer to access ENUM data and locate a URI corresponding to the query.

10. The system of claim 9 wherein the single NP and ENUM data locator structure is located on a signal transfer point (STP).

11. The system of claim 9 wherein the single NP and ENUM data locator structure is located on a service control point (SCP).

12. The system of claim 9 wherein the single NP and ENUM data locator structure is located on a server.

13. A computer program product comprising computer executable instructions embodied in a non-transitory computer readable medium for performing steps when executed by a computer comprising:

(a) receiving a query including a telephone number (TN), wherein the query includes one of a NP query for requesting NP data and an ENUM query for requesting ENUM data;

(b) accessing a single NP and ENUM data locator structure to locate a pointer corresponding to the TN, wherein the single NP and ENUM data locator structure includes an index structure shared by the NP data and the ENUM data;

(c) in response to the query being a NP query, using the pointer to locate NP data, and returning the NP data; and

(d) in response to the query being an ENUM query, using the pointer to locate at least one uniform resource indicator (URI), and returning at the least one URI.
