System and method for major trading area (MTA) routing in a telecommunications network
View Patent ↗A method includes determining all telephone numbers to which a selected CLLI can terminate calls, wherein the CLLI is associated with one or more major trading areas (MTAs), creating a FROM-TO relationship between at least a subset of TNs in the one or more MTAs and the TNs to which the selected CLLI can terminate calls, and provisioning the FROM-TO relationship on a core routing engine accessible to a switch. A system includes a local route manager (LRM) configured to receive input designating a CLLI as available for intra-MTA routing, the CLLI being associated with one or more MTAs, a cluster generator configured to create a first set of all telephone numbers (TNs) handled by the CLLI, a second set of selected TNs in the one or more MTAs, and an association between the first set and the second set, and a provisioning module configured to provision the association between the first set and the second set on a core routing engine to identify calls between TNs of the sets as local in jurisdiction.
1. A system comprising:
a cluster generation module operable to generate:
a first cluster comprising a first set of one or more telephone numbers (TNs) associated with one or more major trading areas (MTAs); and
a second cluster comprising a second set of one or more TNs associated with one or more MTAs, wherein a call between the first set of one or more TNs and the second set of one or more TNs is an intra-MTA call;
one or more tables operable to store at least the first cluster, the second cluster, and a set of terms of use for a direct connection to a selected common language location identifier (CLLI); and
a provisioning module operable to provision the call in a local jurisdiction relationship if the call satisfies the set of terms of use for the direct connection to the selected CLLI.
2. A non-transitory computer-readable medium having instructions stored thereon, the instructions, when executed by a processing device, enabling the processing device to perform the operations of:
determining that a first telephone number (TN) and a second TN are associated with one or more major trading areas (MTAs), such that a call therebetween is an intra-MTA call;
determining whether a call made between the first TN and the second TN satisfies terms of use of a direct connection to a selected common language location identifier (CLLI); and
provisioning the first TN and the second TN in a local jurisdiction relationship if a call between the first TN and the second TN satisfies terms of use of the direct connection.
3. A non-transitory computer-readable medium having instructions stored thereon, the instructions, when executed by a processing device, enabling the processing device to perform the operations of:
determining a set of one or more telephone numbers (TNs) to which a selected common language location identifier (CLLI) can terminate calls, wherein the selected CLLI is associated with one or more major trading areas (MTAs);
creating a FROM-TO relationship between at least a subset of telephone numbers in the one or more MTAs and the set of one or more TNs to which the selected CLLI can terminate calls; and
provisioning the FROM-TO relationship on a core routing engine accessible to a switch.
4. The system as recited in claim 1 , wherein the direct connection bypasses a local exchange carrier (LEC) network.
5. The system as recited in claim 1 , wherein the provisioning module is operable to provision the first cluster and the second cluster on a core routing engine.
6. The system as recited in claim 5 , wherein the cluster generation module is operable to generate at least one of the first and second clusters by:
determining a rate center associated with the selected CLLI; and
looking up TNs associated with the rate center in a local exchange routing guide (LERG) database.
7. The system as recited in claim 1 , wherein a TN associated with at least one of the first and second clusters has the form:
NPA-NXX if the TN is not associated with a wireless endpoint; and
NPA-NXX-X if the TN is associated with a wireless endpoint.
8. The non-transitory computer-readable medium as recited in claim 2 , wherein the direct connection enables bypassing a local exchange carrier (LEC) network.
9. The non-transitory computer-readable medium as recited in claim 2 , further enabling the processing device to perform the operations of:
adding the first TN to a first cluster of TNs and the second TN to a second cluster of TNs.
10. The non-transitory computer-readable medium as recited in claim 9 , further enabling the processing device to perform the operations of:
provisioning the first cluster and the second cluster on a core routing engine.
11. The non-transitory computer-readable medium as recited in claim 10 , wherein the operation of determining that the first TN and the second TN are associated with one or more MTAs comprises:
determining a rate center associated with the first TN; and
looking up TNs associated with the rate center in a local exchange routing guide (LERG) database.
12. The non-transitory computer-readable medium as recited in claim 2 , wherein the first TN has the form:
NPA-NXX if the first TN is not associated with a wireless endpoint; and
NPA-NXX-X if the first TN is associated with a wireless endpoint.
13. The non-transitory computer-readable medium as recited in claim 3 , further enabling the processing device to perform the operations of:
provisioning TNs to which the selected CLLI can terminate calls as a group on the core routing engine.
14. The non-transitory computer-readable medium as recited in claim 3 , further enabling the processing device to perform the operations of:
provisioning the at least a subset of TNs as a group on the core routing engine.
15. The non-transitory computer-readable medium as recited in claim 3 , further enabling the processing device to perform the operations of:
determining a rate center associated with the selected CLLI.
16. The non-transitory computer-readable medium as recited in claim 15 , further enabling the processing device to perform the operations of:
determining the at least a subset of TNs by looking up TNs of the rate center in a local exchange routing guide (LERG) data base.
17. The non-transitory computer-readable medium as recited in claim 3 , wherein the at least a subset of TNs comprises TNs associated with wireless endpoints.
18. The non-transitory computer-readable medium as recited in claim 3 , further enabling the processing device to perform the operations of:
determining the at least a subset of TNs based on an attribute specified in a traffic exchange agreement.
19. The non-transitory computer-readable medium as recited in claim 18 , enabling the processing device to perform the operations of:
if the attribute specifies only wireless originated calls, determining TNs in the one or more MTAs associated with wireless networks.
20. The non-transitory computer-readable medium as recited in claim 3 , further enabling the processing device to perform the operations of:
