Abstract

A system for obtaining information relating to an idle mobile station in a cellular network is provided. The system includes a computing platform which is in communication with a radio network controller of the cellular network. The computing platform is configured for (i) generating and sending an input signal through the radio network controller to the radio access network; and (ii) identifying in data outputted by the radio network controller an output signal resulting from the input signal, the output signal including information relating to at least one idle mobile station.

Claims

1. A method comprising:

determining, by an idle mobile station, that a Cell Camping Threshold message is received from a cell, wherein the Cell Camping Threshold message includes a Cell Camping Threshold parameter;

simulating a Cell Camping Threshold update by the idle mobile station using the Cell Camping Threshold parameter;

determining based on the simulating that the idle mobile station would camp on another cell using the Cell Camping Threshold parameter; and

transmitting a reporting event to a radio access network indicating that the idle mobile station would camp on another cell using the Cell Camping Threshold parameter, wherein the reporting event comprises a Camping Cell Determination decision indicating, at least in part, a preferred camping cell for the idle mobile station.

2. The method of claim 1, wherein the determining includes monitoring a native Camping Cell Determination (CCD) module of the idle mobile station to determine that the Cell Camping Threshold message is received.

3. The method of claim 2, wherein the monitoring is performed by a CCD simulator of the idle mobile station.

4. The method of claim 1, further comprising:

activating, by the idle mobile station a reporting mode based, at least in part, on receiving a reporting mode activation message by the idle mobile station; and

monitoring a native a Camping Cell Determination (CCD) module of the idle mobile station by a CCD simulator of the idle mobile station.

5. The method of claim 1, wherein the reporting event includes, at least in part, Global Positioning System (GPS) coordinates for the idle mobile station.

6. The method of claim 1, further comprising:

activating a reporting mode by the idle mobile station based on receiving a reporting mode activation message.

7. The method of claim 6, further comprising:

deactivating the reporting mode by the idle mobile station based on receiving a reporting mode deactivation message.

8. A mobile station comprising a Camping Cell Determination (CCD) simulator, the mobile station being configured for:

determining by the mobile station that a Cell Camping Threshold message is received from a cell, wherein the Cell Camping Threshold message includes a Cell Camping Threshold parameter;

simulating a Cell Camping Threshold update by the mobile station using the Cell Camping Threshold parameter;

determining based on the simulating that the mobile station would camp on another cell using the Cell Camping Threshold parameter; and

transmitting a reporting event to a radio access network indicating that the mobile station would camp on another cell using the Cell Camping Threshold parameter, wherein the reporting event comprises a Camping Cell Determination decision indicating, at least in part, a preferred camping cell for the mobile station.

9. The mobile station of claim 8, the mobile station being further configured for:

activating a reporting mode based, at least in part, on receiving a reporting mode activation message.

10. The mobile station of claim 9, wherein the determining includes monitoring a native CCD module of the mobile station by the CCD simulator to determine that the Cell Camping Threshold message is received.

11. The mobile station of claim 8, wherein the reporting event includes, at least in part, Global Positioning System (GPS) coordinates for the mobile station.

12. The mobile station of claim 8, the mobile station being further configured for:

activating a reporting mode based on receiving a reporting mode activation message.

13. The mobile station of claim 12, the mobile station being further configured for:

deactivating the reporting mode based on receiving a reporting mode deactivation message.

14. At least one non-transitory computer-readable medium encoded with instructions that, when executed by a processor, perform:

determining that a Cell Camping Threshold message is received by an idle mobile station from a cell, wherein the Cell Camping Threshold message includes a Cell Camping Threshold parameter;

simulating a Cell Camping Threshold update using the Cell Camping Threshold parameter;

determining based on the simulating that the idle mobile station would camp on another cell using the Cell Camping Threshold parameter; and

transmitting a reporting event to a radio access network indicating that the idle mobile station would camp on another cell using the Cell Camping Threshold parameter, wherein the reporting event comprises a Camping Cell Determination decision indicating, at least in part, a preferred camping cell for the idle mobile station.

15. The at least one non-transitory computer-readable medium of claim 14, further encoded with instructions that, when executed by the processor, perform:

activating a reporting mode based, at least in part, on receiving a reporting mode activation message.

16. The at least one non-transitory computer-readable medium of claim 15, further encoded with instructions that, when executed by a processor, perform:

deactivating the reporting mode based on receiving a reporting mode deactivation message.
