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:

generating and sending, using a radio network controller, at least one input signal to at least one idle mobile station within a radio access network, wherein the at least one input signal includes, at least in part, instructions for simulating a modification of a Cell Camping Threshold by the at least one idle mobile station and wherein the simulating is to be performed by the at least one idle mobile station without modifying a current Cell Camping Threshold for the at least one idle mobile station; and

determining information for the radio access network based, at least in part, on whether a reporting event, which indicates a preferred camping cell for the at least one idle mobile station for the simulated modification of the Cell Camping Threshold, is received by the radio network controller from the at least one idle mobile station.

2. The method of claim 1, wherein the reporting event includes global-positioning system (GPS) data for the at least one idle mobile station.

3. The method of claim 1, further comprising:

activating a reporting mode for a particular cell in communication with the at least one idle mobile station prior to the determining.

4. The method of claim 3, further comprising:

de-activating the reporting mode for the particular cell following the determining.

5. The method of claim 1, further comprising:

selecting a segmentation parameter for a particular cell of the radio access network in communication with a plurality of idle mobile stations, wherein the segmentation parameter is associated with a particular segmentation of the particular cell;

determining a plurality of Cell Camping Thresholds for the segmentation parameter; and

determining information for the radio access network based, at least in part, on whether a reporting event is received from any of the plurality of idle mobile stations for each of the plurality of Cell Camping Thresholds.

6. The method of claim 5, further comprising:

communicating a first Point To Multi Point (PTMP) message to the radio network controller to activate a reporting mode for the particular cell prior to determining the information for the radio access network.

7. The method of claim 6, further comprising:

communicating a second PTMP message to the radio network controller to de-activate the reporting mode for the particular cell following the determining.

8. The method of claim 5, further comprising:

providing an indication of the plurality of idle mobile stations in relation to the particular segmentation of the particular cell.

9. A system for obtaining information relating to at least one idle mobile station in a radio access network, the system comprising a computing platform being in communication with a radio network controller of said radio access network and being configured for:

generating and sending, using the radio network controller, at least one input signal to at least one idle mobile station within the radio access network, wherein the at least one input signal includes, at least in part, instructions for simulating a modification of a Cell Camping Threshold for the at least one idle mobile station and wherein the simulating is to be performed by the at least one idle mobile station without modifying a current Cell Camping Threshold for the at least one idle mobile station; and

determining information for the radio access network based, at least in part, on whether a reporting event, which indicates a preferred camping cell for the at least one idle mobile station for the simulated modification of the Cell Camping Threshold, is received by the radio network controller from the at least one idle mobile station.

10. The system of claim 9, wherein the reporting event includes global-positioning system (GPS) data for the at least one idle mobile station.

11. The system of claim 9, wherein the computing platform is further configured for:

12. The system of claim 11, wherein the computing platform is further configured for:

de-activating the reporting mode for the particular cell following the determining.

13. The system of claim 9, wherein the computing platform is further configured for:

selecting a segmentation parameter for a particular cell of the radio access network in communication with a plurality of idle mobile stations, wherein the segmentation parameter is associated with a particular segmentation of the particular cell;

determining a plurality of Cell Camping Thresholds for the segmentation parameter; and

determining information for the radio access network based, at least in part, on whether a reporting event is received from any of the plurality of idle mobile stations for each of the plurality of Cell Camping Thresholds.

14. The system of claim 13, wherein the computing platform is further configured for:

communicating a first Point To Multi Point (PTMP) message to the radio network controller to activate a reporting mode for the particular cell prior to determining the information for the radio access network.

15. The system of claim 14, wherein the computing platform is further configured for:

communicating a second PTMP message to the radio network controller to de-activate the reporting mode for the particular cell following the determining.
