Abstract

This patent discloses a method to communicate between a femtocell base station and mobile devices. The method may include identifying as an alert group a set of mobile devices presently in communication with the femtocell base station and whose unique identifiers are preregistered with the femtocell base station. A first mobile device and a second mobile device may be in the set of femtocell service region mobile devices. The femtocell base station may receive a call from a third mobile device. If the call is for the second mobile device, then the method may send a paging message from the femtocell base station. The paging message may include a first unique identifier associated with the first mobile device.

5. The method of claim 1, where if the second mobile device answered the paging message and the first mobile device answered the paging message, the method further comprising:

determining whether to disconnect the first mobile device from a traffic channel with the femtocell base station.

6. The method of claim 1, further comprising:

determining whether a conference call feature has been enabled in the femtocell base station.

7. The method of claim 1, further comprising:

if the received call is for the femtocell base station, sending a paging message from the femtocell base station in response to the received call, where the paging message includes the first unique identifier associated with the first mobile device and the second unique identifier associated with the second mobile device.

8. The method of claim 7, further comprising:

accessing a phone number assigned to the femtocell base station; and

if the first mobile device answered the paging message, determining whether to block the second mobile device from answering the paging message.

27. The method of claim 1, further comprising preregistering at least one mobile device as a visiting mobile device.

28. The method of claim 27, further comprising re-registering the at least one mobile device as an in-home mobile device when the mobile device communicates with the femtocell base station for longer than a threshold time period.

29. The method of claim 1, further comprising implementing a predetermined paging message order.

9. An apparatus to facilitate communications between a femtocell base station and mobile devices, the apparatus comprising:

a processor to identify as an alert group a set of mobile devices presently in communication with the femtocell base station and whose unique identifiers are preregistered with the femtocell base station as in-home mobile devices, where a first mobile device and a second mobile device are in the alert group;

a transceiver to receive a call in the femtocell base station from a third device;

wherein the processor determines whether the received call includes a second unique identifier associated with the second mobile device; and

wherein the transceiver alerts the first mobile device by sending a paging message from the femtocell base station if the received call includes the second unique identifier associated with the second mobile device, where the paging message includes a first unique identifier associated with the first mobile device.

10. The apparatus of claim 9, where the paging message further includes the second unique identifier associated with the second mobile device.

11. An apparatus to facilitate communications between a femtocell base station and mobile devices, the apparatus comprising:

means for identifying as an alert group a set of mobile devices presently in communication with the femtocell base station and whose unique identifiers are preregistered with the femtocell base station as in-home mobile devices, where a first mobile device and a second mobile device are in the alert group;

means for receiving a call in the femtocell base station from a third device;

means for determining at the femtocell base station whether the received call includes a second unique identifier associated with the second mobile device; and

means for alerting the first mobile device, where the means for alerting comprises means for sending a paging message from the femtocell base station if the received call includes the second unique identifier associated with the second mobile device, where the paging message includes a first unique identifier associated with the first mobile device.

12. The apparatus of claim 11, where the paging message is a first paging message, the apparatus further comprising:

means for sending a second paging message from the femtocell base station after sending the first paging message, where the second paging message includes the second unique identifier associated with the second mobile device.

13. The apparatus of claim 11, further comprising:

means for sending a paging message from the femtocell base station in response to the received call, where the paging message includes the first unique identifier associated with the first mobile device and the second unique identifier associated with the second mobile device.

14. The apparatus of claim 11, further comprising:

means for determining whether the second mobile device answered the paging message if the received call is for the second mobile device; and

means for determining whether the first mobile device answered the paging message if the second mobile device did not answer the call.

15. The apparatus of claim 11, further comprising:

means for determining whether to disconnect the first mobile device from a traffic channel with the femtocell base station if the second mobile device answered the paging message and the first mobile device answered the paging message.

16. The apparatus of claim 11, further comprising:

means for determining whether a conference call feature has been enabled in the femtocell base station.

17. The apparatus of claim 11, further comprising:
