Geographic trunk groups
First Claim
1. A method for routing an Internet Protocol (IP)-based call through a first IP-based network to a second IP-based network, the method comprising:
- receiving an IP-based call request in the first network;
identifying one or more geographic trunk groups that can be used to route the call request out of the first network, wherein each of the one or more geographic trunk groups represents a logical grouping of one or more IP trunk groups between the first IP-based network and the second IP-based network;
selecting one of the one or more geographic trunk groups; and
routing the received call request via the selected geographic trunk group to an IP address associated with the selected geographic trunk group;
wherein the one or more geographic trunk groups utilize one or more load balance servers (LBS) to aggregate signaling of the one or more IP trunk groups in the one or more geographic trunk groups.

Abstract
Embodiments of the invention include a method for routing an Internet Protocol (IP)-based call through a first IP-based network to a second IP-based network. The method includes receiving an IP-based call request in the first network; identifying one or more geographic trunk groups that can be used to route the call request out of the first network, wherein each of the one or more geographic trunk groups represents a logical grouping of one or more IP trunk groups between the first IP-based network and the second IP-based network; selecting one of the one or more geographic trunk groups; and routing the received call request via the selected geographic trunk group to an IP address associated with the selected geographic trunk group. Other embodiments are also disclosed.

8. A system for routing IP-based calls through a backbone network to a carrier network, the system comprising:
-
a core routing engine operable to receive a call setup request and identify one or more geographic trunk groups through which the call setup request can be routed, based at least in part on a telephone number in the call setup request, the core routing engine further operable to select one of the one or more identified geographic trunk groups and route the call setup request to an internal IP address associated with the selected geographic trunk group; an IP media gateway (IPMG) associated with the internal IP address, the IPMG in the backbone network operable to receive the call setup request and route the call setup request to one of a plurality of load balance servers (LBS) associated with the one or more identified geographic trunk groups and associated with a plurality of carrier edge nodes in the carrier network, where the IPMG is associated with multiple internal IP addresses; and a LBS to route the call setup request to one of a plurality of IP addresses associated with the plurality of carrier edge nodes, the LBS to aggregate a plurality of carrier servers at the carrier network into a single destination trunk group (DTG) label for routing purposes of the one or more identified geographic trunk groups. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. An article of manufacture comprising:
-
a computer readable medium including data that, when accessed by a computer, cause the computer to perform operations comprising; receiving an IP-based call request in the first network; identifying one or more geographic trunk groups that can be used to route the call request out of the first network, wherein each of the one or more geographic trunk groups represents a logical grouping of one or more IP trunk groups between the first IP-based network and the second IP-based network; selecting one of the one or more geographic trunk groups; and routing the received call request via the selected geographic trunk group to an IP address associated with the selected geographic trunk group; wherein the one or more geographic trunk groups utilize one or more load balance servers (LBS) to aggregate signaling of the one or more IP trunk groups in the one or more geographic trunk groups. - View Dependent Claims (16, 17, 18, 19)
