Abstract

Idle mode reselection is presented herein. A virtual neighbor component can create at least one virtual neighbor object and associate the at least one virtual neighbor object with wireless access points. Further, a reselection component can facilitate idle mode reselection between a base station and a wireless access point of the wireless access points based on the at least one virtual neighbor object.

Claims

1. A method, comprising:

creating, by a system comprising a processor, a virtual neighbor object comprising a channel number and a scrambling code;

referencing, by the system, a plurality of femtocell devices utilizing the virtual neighbor object;

sending, by the system, neighbor information directed to a mobile device, wherein the neighbor information comprises the virtual neighbor object and represents channels of neighboring femtocell devices within a defined proximity to the mobile device; and

in response to the sending the neighbor information, granting, based on the virtual neighbor object, an idle mode reselection between a wireless access point device and a femtocell device of the plurality of femtocell devices.

2. The method of claim 1, wherein the granting the idle mode reselection comprises granting the idle mode reselection based on an access restriction associated with the femtocell device.

3. The method of claim 2, wherein the access restriction comprises an access control list associated with the femtocell device.

4. The method of claim 1, wherein the sending the neighbor information comprises directing the femtocell device to transmit the neighbor information to the mobile wireless device.

5. The method of claim 1, wherein the granting the idle mode reselection comprises:

assigning an access control parameter to the femtocell device; and

permitting the idle mode reselection based on the access control parameter.

6. A system, comprising:

a memory to store computer-executable instructions; and

a processor, communicatively coupled to the memory, that facilitates execution of the computer-executable instructions to perform operations, comprising;

generating a virtual neighbor object comprising a channel number and a scrambling code;

associating the virtual neighbor object with femtocell devices;

sending neighbor data directed to a mobile wireless device, wherein the neighbor data comprises the virtual neighbor object and represents channels of neighboring femtocell devices within a defined proximity to the mobile device; and

subsequent to the sending of the neighbor data, permitting an idle mode reselection between a base station device and a femtocell device of the femtocell devices using the virtual neighbor object.

7. The system of claim 6, wherein the operations further comprise:

defining an access restriction associated with the femtocell device.

8. The system of claim 7, wherein the permitting the idle mode reselection comprises authorizing the idle mode reselection between the base station device and the femtocell device based on the access restriction.

9. The system of claim 8, wherein the access restriction comprises an access control list associated with the femtocell device.

10. The system of claim 6, wherein the sending the neighbor data comprises directing the femtocell device to transmit the neighbor data to the mobile wireless device.

11. The system of claim 6, wherein the permitting the idle mode reselection comprises:

assigning an access control parameter to the femtocell device; and

permitting the idle mode reselection based on the access control parameter.

12. The system of claim 6, wherein the base station device comprises a Long Term Evolution access point device.

13. The system of claim 6, wherein the femtocell device comprises a Bluetooth™

access point device.

14. The system of claim 6, wherein the femtocell device comprises a worldwide interoperability for microwave access point device.

15. The system of claim 6, wherein the femtocell device comprises an Institute of Electrical and Electronics Engineers 802.11x based device.

16. A non-transitory computer-readable storage medium comprising computer executable instructions that, in response to execution, cause a mobile device comprising a processor to perform operations, comprising:

receiving neighbor data including a virtual neighbor object that comprises channel data that references a channel number and scrambling code data that references a scrambling code, wherein the virtual neighbor object is associated with femtocell devices and represents channels of proximate femtocell devices within a defined proximity to the mobile device; and

in response to the receiving of the neighbor data, reselecting, based on the virtual neighbor object, between a base station device and a femtocell device of the femtocell devices.

17. The non-transitory computer-readable storage medium of claim 16, wherein the receiving the neighbor data comprises receiving the neighbor data from the femtocell device.

18. The non-transitory computer-readable storage medium of claim 16, wherein the reselecting comprises reselecting between the base station device and the femtocell device based on an access restriction.

19. The non-transitory computer-readable storage medium of claim 18, wherein the access restriction comprises an identification associated with the mobile device.

20. The non-transitory computer-readable storage medium of claim 18, wherein the access restriction references a signal quality associated with a communication between the femtocell device and mobile device.
