Closed-loop optimization of a wireless network using an autonomous vehicle
First Claim
1. A method comprisingtransmitting a path to a drone;
- receiving, at a self-organizing network (SON), RF data measured by the drone while the drone traverses the path;
upon determining a problem at a location on the path traversed by the drone in a wireless network based on the received RF data, transmitting an action to change a parameter of a wireless network;
after transmitting the action to change the parameter, instructing the drone via the SON to revisit the location on the path where the problem was determined;
re-measuring RF data at the location on the path; and
evaluating the re-measured RF data at the SON to determine whether the problem was resolved.

Abstract
Embodiments herein use a real-time closed-loop system to optimize a wireless network. The system includes a drone controlled by a self-organizing network (SON) to retrieve RF data corresponding to the wireless network. In one embodiment, the SON provides the drone with a predetermined path through the coverage area of the wireless network. As the drone traverses the path, a RF scanner mounted on the drone collects RF data. The drone transmits this data to the SON which processes the RF data to identify problems in the wireless network (e.g., cell tower interference). The SON generates one or more actions for correcting the identified problem and transmits these actions to a wireless network controller. Once the wireless network controller performs the action, the SON instructs the drone to re-traverse the portion of the path to determine if the problem has been resolved.

13. A communication system, comprising:
-
an autonomous vehicle (AV); a wireless network comprising a plurality of cell towers controllable by a network controller to establish a wireless network; a SON configured to; transmit a path to the AV to traverse in the wireless network; receive RF data measured by the AV while the AV traverses the path; upon determining a problem at a location on the path traversed by the AV in the wireless network based on the received RF data to determine whether the problem is of a type that requires human intervention; transmit an action to the network controller to change a parameter of the wireless network to remedy the problem; instruct the AV to re-measure RF data at the location on the path; and evaluate the re-measured RF data at the SON to determine whether the problem was resolved. - View Dependent Claims (14, 15, 16, 17)
