Abstract

Communication networks and methods are disclosed for selectively applying call forwarding between a mobile device and a fixed line device based on the location of the mobile device. A communication network includes a call control function that receives a call attempt to a mobile directory number. Responsive to the call attempt, the call control function identifies a location of the mobile device, and determines whether to apply call forwarding based on the location of the mobile device. If call forwarding is applied, then the call control function forwards the call attempt to the fixed line device instead of the mobile device. A similar process is performed for a call attempt to the fixed line device for forwarding the call to the mobile device.

Claims

1. A system comprising:

a call control function operable to receive a call attempt to a first directory number associated with a fixed line device of a user, to identify a location of a mobile device of the user, to determine whether to apply call forwarding from the fixed line device to the mobile device based on the location of the mobile device, and to forward the call attempt to a second directory number associated with the mobile device of the end user responsive to a determination that call forwarding applies;

the call control function is further operable to identify a fixed line tariff for the call, to identify a mobile tariff for the call, and to initiate charging for the call based on a combination of the fixed line tariff and the mobile tariff to spread charging across both directory numbers.

2. The system of claim 1 wherein:

the call control function is further operable to route the call attempt to the first directory number responsive to a determination not to apply call forwarding.

3. The system of claim 1 wherein:

the call control function is further operable to determine if the location of the mobile device is within a threshold distance of a location of the fixed line device.

4. The system of claim 1 wherein:

the call control function is further operable to determine if the location of the mobile device is within a zone predefined by the service provider as corresponding with the fixed line device.

5. The system of claim 4 wherein:

the zone predefined by the service provider comprises a home zone representing an area surrounding a home phone of the user.

6. The system of claim 1 wherein:

the call control function is further operable to initiate charging for the call based on the mobile tariff.

7. The system of claim 1 wherein:

the call control function is further operable to initiate charging for the call based on the fixed line tariff.

8. A method comprising:

receiving a call attempt to a first directory number associated with a fixed line device of a user;

identifying a location of a mobile device of the user;

determining whether to apply call forwarding from the fixed line device to the mobile device based on the location of the mobile device;

forwarding the call attempt to a second directory number associated with the mobile device of the end user responsive to a determination that call forwarding applies;

identifying a fixed line tariff for the call;

identifying a mobile tariff for the call; and

initiating charging for the call based on a combination of the fixed line tariff and the mobile tariff to spread charging across both directory numbers.

9. The method of claim 8 further comprising:

routing the call attempt to the first directory number responsive to a determination not to apply call forwarding.

10. The method of claim 8 wherein determining whether to apply call forwarding based on the location of the mobile device further comprises:

determining if the location of the mobile device is within a threshold distance of a location of the fixed line device.

11. The method of claim 8 wherein determining whether to apply call forwarding based on the location of the mobile device further comprises:

determining if the location of the mobile device is within a zone predefined by the service provider as corresponding with the fixed line device.

12. The method of claim 11 further comprising:

the zone predefined by the service provider comprises a home zone representing an area surrounding a home phone of the user.

13. A method comprising:

receiving a call attempt to a fixed line device of a user;

identifying a location of a mobile device of the user;

determining if the mobile device is located in a zone predefined as corresponding with the fixed line device;

applying call forwarding of the call attempt from the fixed line device to the mobile device if the mobile device is located in the predefined zone;

identifying a fixed line tariff for the call;

identifying a mobile tariff for the call;

initiating charging for the call based on a combination of the fixed line tariff and the mobile tariff to spread charging across directory numbers for the fixed line device and the mobile device;

while the call is in progress, identifying that the mobile device moves from the predefined zone to another zone; and

switching charging to the mobile tariff.

14. The method of claim 13 further comprising:

waiting a threshold time period after the mobile device leaves the predefined zone before switching the charging to the mobile tariff.

15. The method of claim 13 further comprising:

sending a notification to the mobile device indicating that tariff is changing.

16. The method of claim 15 wherein:

the notification to the mobile device comprises a text message.
