Abstract

A mobile communications device may determine whether to report information regarding operation of the mobile device on a mobile network. The determination may be based on a reporting parameter set by a network control device and received via a broadcast message from a radio access node. The mobile device may compare the value of the reporting parameter to a randomly generated number. Based on the comparison, the mobile device may determine whether or not to provide information regarding operation of the mobile device or the radio access node to the network control device. The network control device may adjust the value of the reporting parameter to control the likelihood that a mobile device will report.

Claims

1. A method comprising:

receiving, from a plurality of radio access nodes, information indicating availability of the radio access nodes;

based on the availability information received from the radio access nodes, determining that a current operating condition of a mobile network corresponds to normal operations;

requesting information regarding mobile network operating conditions from a plurality of mobile devices in communication with the radio access nodes by;

setting a reporting parameter to a first value, and

instructing each of the radio access nodes to transmit a respective broadcast message that includes the first value for the reporting parameter;

receiving a first plurality of messages from a first subset of mobile devices, each message in the first plurality of messages including location information for a respective mobile device in the first subset; and

using the location information received from the first subset of mobile devices and the availability information received from the radio access nodes to define at least one coverage area;

receiving, from a subset of the radio access nodes, information indicating availability of the subset of the radio access nodes;

based on the information received from the subset of the radio access nodes, determining that the current operating condition of the mobile network corresponds to impaired operations;

requesting updated information regarding mobile network operating conditions by;

setting the reporting parameter to a second value, and

instructing each radio access node in the subset of the radio access nodes to transmit a second broadcast message that includes the second value for the reporting parameter, wherein the second value differs from the first value;

receiving a second plurality of messages from a second subset of mobile devices, each message in the second plurality of messages including location information for a respective mobile device in the second subset; and

using the location information for the second subset of mobile devices and the availability information received from the subset of the radio access nodes to define at least one revised coverage area.

2. The method of claim 1, wherein the second value increases a likelihood that a selected mobile device provides a respective message including location information for the selected mobile device.

3. The method of claim 1, further comprising:

instructing the subset of the radio access nodes to include a modifier in the second broadcast message, wherein the modifier defines a modification to the second value based on a timing advance.

4. The method of claim 3, wherein the modifier increases a likelihood that the second subset of mobile devices includes a mobile device located proximate to a perimeter of the revised coverage area.

5. The method of claim 1, further comprising:

instructing a selected radio access node in the subset of the radio access nodes to transmit a third broadcast message that includes a modifier based on a historical distribution of mobile devices served by the selected radio access node.

6. The method of claim 1, further comprising:

instructing the radio access nodes to specify at least some of the information regarding mobile network operating conditions in the respective broadcast message.

7. The method of claim 1, wherein each message of the first plurality of messages further includes at least one of a history of recent operations of the respective mobile device, or a signal strength of a respective radio access node with which the respective mobile device communicates.

8. The method of claim 1, further comprising instructing each of the radio access nodes to transmit the respective broadcast message via a respective control channel.

9. The method of claim 1, wherein the respective broadcast message further includes an indication of a trigger event, each respective mobile device in the first subset being configured to provide a respective message in the first plurality of messages based on the trigger event.

10. The method of claim 1, further comprising determining, based on the availability information received from the subset of the radio access nodes, a repair priority of a particular radio access node included in the subset of the radio access nodes.

11. A system comprising:

a plurality of radio access nodes, and

a network control device, wherein the network control device is configured for;

receiving, from the plurality of radio access nodes, information indicating availability of the radio access nodes;

based on the availability information received from the radio access nodes, determining that a current operating condition of a mobile network corresponds to normal operations;

requesting information regarding mobile network operating conditions from a plurality of mobile devices in communication with the radio access nodes by;

setting a reporting parameter to a first value, and

instructing each of the radio access nodes to transmit a respective broadcast message that includes the first value for the reporting parameter;

receiving a first plurality of messages from a first subset of mobile devices, each message in the first plurality of messages including location information for a respective mobile device in the first subset; and

using the location information received from the first subset of mobile devices and the availability information received from the radio access nodes to define at least one coverage area;

receiving, from a subset of the radio access nodes, information indicating availability of the subset of the radio access nodes;

based on the information received from the subset of the radio access nodes, determining that the current operating condition of the mobile network corresponds to impaired operations;

requesting updated information regarding mobile network operating conditions by;

setting the reporting parameter to a second value, and

instructing each radio access node in the subset of the radio access nodes to transmit a second broadcast message that includes the second value for the reporting parameter, wherein the second value differs from the first value;

receiving a second plurality of messages from a second subset of mobile devices, each message in the second plurality of messages including location information for a respective mobile device in the second subset; and

using the location information for the second subset of mobile devices and the availability information received from the subset of the radio access nodes to define at least one revised coverage area.

12. The system of claim 11, wherein the second value increases a likelihood that a selected mobile device provides a respective message including location information for the selected mobile device.

13. The system of claim 11, further comprising:

instructing the subset of the radio access nodes to include a modifier in the second broadcast message, wherein the modifier defines a modification to the second value based on a timing advance.

14. The system of claim 13, wherein the modifier increases a likelihood that the second subset of mobile devices includes a mobile device located proximate to a perimeter of the revised coverage area.

15. The system of claim 11, further comprising:

instructing a selected radio access node in the subset of the radio access nodes to transmit a third broadcast message that includes a modifier based on a historical distribution of mobile devices served by the selected radio access node.

16. The system of claim 11, further comprising:
