Abstract

Methods and Systems are provided for routing a call to a landline communication unit or a wireless communication unit based on the availability of the wireless communication unit. A call placed to a landline communication unit is routed to the wireless communication unit if the wireless communication unit is determined available. Otherwise, the call is routed to the landline communication unit.

Claims

1. A method for routing a call, the method comprising:

determining, with a processor, an availability of a wireless communication unit associated with a landline communication unit, a called party destination number of the call corresponding to a first destination number associated with the landline communication unit;

determining, with the processor, whether the call is to be routed to the wireless communication unit instead of the landline communication unit based on the availability of the wireless communication unit; and

in response to the wireless communication unit being determined to be available, replacing, with the processor, a calling party destination number of the call with a second destination number associated with the wireless communication unit to route the call to the wireless communication unit.

2. The method of claim 1, further comprising:

routing the call to the landline communication unit when the call is originated by the wireless communication unit.

3. The method of claim 1, wherein determining the availability of the wireless communication unit comprises:

sending a location request to a home location register; and

analyzing a response to the location request.

4. The method of claim 1, wherein the wireless communication unit is determined to be available when the wireless communication unit is determined to be active.

5. The method of claim 1, wherein the wireless communication unit is determined to be available when the wireless communication unit is determined to be not busy.

6. The method of claim 1 further comprising:

sending an indication to the wireless communication unit that the call is being routed to the wireless communication unit.

7. The method of claim 1 further comprising:

playing a message to a calling party before the call is routed.

8. The method of claim 1 further comprising:

receiving an input via an interactive voice response system to disable performance of determining the availability of the wireless communication unit and routing the call based on the availability of the wireless communication unit.

9. The method of claim 1, further comprising:

routing the call to the landline communication unit in response to the wireless communication unit being determined to be unavailable.

10. The method of claim 9, wherein routing the call to the landline communication unit in response to the wireless communication unit being determined to be unavailable comprises:

routing the call to the landline communication unit in response to the wireless communication unit being determined to be inactive.

11. The method of claim 9, wherein routing the call to the landline communication unit in response to the wireless communication unit being determined to be unavailable comprises:

routing the call to the landline communication unit in response to the wireless communication unit being determined to be busy.

12. The method of claim 1 further comprising:

providing the wireless communication unit with a distinctive ring in response to routing the call to the wireless communication unit.

13. A tangible computer-readable storage medium comprising instructions which, when executed by a processor, cause the processor to perform operations comprising:

determining an availability of a wireless communication unit associated with a landline communication unit, a called party destination number of a call corresponding to a first destination number associated with the landline communication unit;

determining whether the call is to be routed to the wireless communication unit instead of the landline communication unit based on the availability of the wireless communication unit; and

in response to the wireless communication unit being determined to be available, replacing a calling party destination number of the call with a second destination number associated with the wireless communication unit to route the call to the wireless communication unit.

14. The computer-readable storage medium of claim 13, wherein the operations further comprise:

routing the call to the landline communication unit in response to the wireless communication unit being determined to be unavailable.

15. The computer-readable storage medium of claim 14, wherein routing the call to the landline communication unit in response to the wireless communication unit being determined to be unavailable comprises:

routing the call to the landline communication unit in response to the wireless communication unit being determined to be inactive.

16. The computer-readable storage medium of claim 14, wherein routing the call to the landline communication unit in response to the wireless communication unit being determined to be unavailable comprises:

routing the call to the landline communication unit in response to the wireless communication unit being determined to be busy.

17. The computer-readable storage medium of claim 13, wherein the operations further comprise:

routing the call to the landline communication unit when the call is originated by the wireless communication unit.

18. The computer-readable storage medium of claim 13, wherein the wireless communication unit is determined to be available when the wireless communication unit is determined to be active.

19. The computer-readable storage medium of claim 13, wherein the wireless communication unit is determined to be available when the wireless communication unit is determined to be not busy.

20. The computer-readable storage medium of claim 13, wherein the operations further comprise:

providing the wireless communication unit with a distinctive ring in response to routing the call to the wireless communication unit.

21. A system to route a call, the system comprising:

memory to store first machine readable instructions and second machine readable instructions;

a first network element comprising a first processor to execute the first machine readable instructions to perform first operations comprising;

determining an availability of a wireless communication unit associated with a landline communication unit, a called party destination number of the call corresponding to a first destination number associated with the landline communication unit; and

determining whether the call is to be routed to the wireless communication unit instead of the landline communication unit based on the availability of the wireless communication unit; and

a second network element in communication with the first network element, the second network element comprising a second processor to execute the second machine readable instructions to perform second operations comprising;

in response to the wireless communication unit being determined to be available, replacing a calling party destination number of the call with a second destination number associated with the wireless communication unit to route the call to the wireless communication unit.
