Abstract

Example methods and systems are disclosed to facilitate detection and identification of devices connected to a cellular network and that are causing interference to the cellular network. An example method may include receiving, by a serving base station of the device, a first set of information associated with data communications of a device utilizing a cellular network. The method may further include determining the device is an interfering device based on the first set of information associated with the data communication substantially corresponding with an interfering device profile, and in response tracking the device. During the tracking of the device, a second set of information associated with the data communications from the device may be obtained, and an interfering device type of the device may be determined based on the second set of information. An action may be performed on the interfering device based on its interfering device type.

First claim

What is claimed is:

1. A method, comprising:
receiving, via a cellular network, information corresponding with data communications between a device and the cellular network;
determining, based on correspondence between the information and an interfering device profile, that the data communications cause interference on the cellular network;
determining an interfering device type of the device based on the information; and
performing, based on the interfering device type and while the device is in an active interfering mode, a mitigation action to mitigate the interference on the cellular network caused by the data communications between the device and the cellular network and to transmit with sufficient power to maintain connectivity.

2. The method of claim 1 , wherein the mitigation action includes performing a communication channel modification.

3. The method of claim 1 , wherein the mitigation action includes throttling back a throughput of the device.

4. The method of claim 1 , wherein the mitigation action includes adjusting radio channel allocation instructions that adjusts at least one of a frequency band allocatable to the device, a bit rate allocatable to the device, or a communication protocol for the device.

5. The method of claim 1 , further comprising:
providing a notification to an administrator device associated with an administrator that includes the interfering device type of the device.

6. The method of claim 1 , wherein at least a first portion of the information is provided in a measurement report from the device that includes signal strength measurements of the device and signal quality measurements of the device.

7. The method of claim 6 , wherein the determining of the device is an interfering device type of the device is based on the signal strength measurements satisfying a predetermined signal strength threshold and the signal quality measurements satisfying a predetermined quality threshold.

8. The method of claim 6 , wherein at least a second portion of the information includes at least one of a speed of the device, a location of the device over a time period, a service type, throughput asymmetry between uplink and downlink, a persistence that the device satisfies a predetermined interference threshold, an altitude of the device, an application being executed by the device, and uplink video streaming.

9. The method of claim 1 , wherein the device comprises an unmanned aerial vehicle.

10. A management system, comprising:
one or more processors; and
a non-transitory machine readable medium comprising instructions stored therein, which when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving, via a cellular network, information corresponding with data communications between a device and the cellular network;
determining, based on correspondence between the information and an interfering device profile, that the data communications cause interference on the cellular network and an interfering device type of the device; and
performing, based on the interfering device type and while the device is in an active interfering mode, a mitigation action to mitigate the interference on the cellular network caused by the data communications between the device and the cellular network and to transmit with sufficient power to maintain connectivity.

11. The management system of claim 10 , wherein at least a first portion of the information is provided in a measurement report from the device and that includes signal strength measurements of the device and signal quality measurements of the device.

12. The management system of claim 11 , wherein the determining of the interfering device type of the device is based on the signal strength measurements satisfying a predetermined power threshold and the signal quality measurements satisfying a predetermined quality threshold.

13. The management system of claim 11 , wherein a second portion of the information includes at least one of a speed of the device, a location of the device over a time period, a service type, throughput asymmetry between uplink and downlink, a persistence that the device satisfies a predetermined interference threshold, an altitude of the device, an application being executed by the device, and uplink video streaming.

14. The management system of claim 13 , wherein the interfering device type of the device is determined based on at least the second portion of the information.

15. A user equipment, comprising:
one or more processors; and
a non-transitory machine readable medium comprising instructions stored therein, which when executed by the one or more processors, cause the one or more processors to perform operations comprising:
receiving a first set of information associated with data communications of a device utilizing a cellular network;
providing, via the cellular network, information corresponding to with data communications between the one or more processors and the cellular network;
receiving, in response to providing the information corresponding with data communication between the one or more processors and the cellular network, mitigation instructions to perform a mitigation action to mitigate interference on the cellular network caused by the data communications between the one or more processors and the cellular network and to transmit with at least threshold power to maintain connectivity, wherein the mitigation instructions were provided via the cellular network, to the one or more processors in response to at least one of a management device or a base station, which are part of the cellular network, determining, based on correspondence between the information and an interfering device profile, that the data communications cause interference on the cellular network and an interfering device type of the user equipment; and
executing the mitigation instructions to perform the mitigation action to mitigate the interference on the cellular network caused by the data communications between the one or more processors and the cellular network and to transmit with at least the threshold power to maintain connectivity.
