Claims8
-10. (canceled)
A method of forwarding a call while minimizing cost, the method comprising:
- receiving from a switch a request for call forwarding information;
- determining whether providing the switch with generic call forwarding information will result in cost savings to a called party;
- and
- when providing the switch with the generic call forwarding information will result in cost savings to a called party, providing the generic call forwarding information to the switch in place of call forwarding information that is specific to the called party;
- wherein the generic call forwarding information is predetermined without a particular subscriber's preferences.
2 more elements
-16. (canceled)
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 whether providing a switch with generic call forwarding information will result in cost savings to a called party, and when providing the switch with generic call forwarding information will result in cost savings to a called party, 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.
