Abstract

A second switch receives an indication from a roaming network that a call forwarded by the roaming network has been dropped by the roaming network, and in response to receiving the indication, forwards the call from a first switch.

Claims (18)

1. A network element for forwarding a call while minimizing cost, the network element comprising:

a processor; and

logic that, when applied to the processor, results in

determining that providing a switch with generic call forwarding information will result in cost savings to a called party, and

providing the generic call forwarding information to the switch in place of call forwarding information that is specific to the called party,

wherein a generic number is provided to a roaming network from a home location register along with the generic call forwarding information, the generic number signaling the switch that a call should be dropped from the roaming network, the generic call forwarding information being predetermined without a particular subscriber's preferences.

2. The network element of claim 1 , further comprising:

logic to apply an E.164 address for the switch to determine that providing the switch with generic call forwarding information will result in cost savings to a called party.

3. The network element of claim 1 , further comprising:

logic to

determine that the called party's call forwarding information is the same for a plurality of conditions, and

providing the switch with generic call forwarding information.

4. The network element of claim 1 , further comprising:

receiving a query for call forwarding information for a roaming subscriber;

determining that calls to the roaming subscriber should be forwarded according to the generic call forwarding information;

providing the generic call forwarding information in response to the query in place of forwarding information that is specific to the subscriber.

5. The network element of claim 4 , wherein the call forwarding information includes a routing number to the switch.

6. The network element of claim 4 , wherein the routing number is the same for two or more of forward no-answer, forward busy, and forward do-not-disturb.
