Abstract
A method for managing a wireless connection of an Unmanned Aerial Vehicle (UAV) is described herein. The method may include detecting a handover condition for the UAV within a wireless network, wherein the UAV is connected to a source cell in the wireless network when the handover condition is detected; determining, in response to detecting the handover condition, a target cell in the wireless network based on a flight path of the UAV; and initiating a handover of the UAV from the source cell to the target cell.
Claims17
A method for managing a wireless connection of an Unmanned Aerial Vehicle (UAV), the method comprising:
- detecting, by a controller of a wireless network, a handover condition for the UAV within the wireless network, wherein the UAV is connected to a source cell in the wireless network when the handover condition is detected;
- determining, by the controller in response to detecting the handover condition, a target cell in the wireless network based on a flight path of the UAV;
- and
- initiating, by the controller, a handover of the UAV from the source cell to the target cell,
- wherein initiating the handover further comprises:
- spoofing data transmissions on behalf of the UAV for the duration of a timer,
- wherein the spoofed data transmissions include messages to keep links associated with the UAV active, and
- wherein the spoofed data transmissions include an address of the UAV to indicate that the spoofed data transmissions originated from the UAV instead of the controller.
A non-transitory computer-readable storage medium storing instructions which, when executed by a set of one or more processors of a computing device of a wireless network controller of a wireless network, cause the computing device to:
- detect a handover condition for the UAV within the wireless network, wherein the UAV is connected to a source cell in the wireless network when the handover condition is detected;
- determine, in response to detecting the handover condition, a target cell in the wireless network based on a flight path of the UAV;
- and
- initiate a handover of the UAV from the source cell to the target cell, wherein initiating the handover further comprises:
- spoofing data transmissions on behalf of the UAV for the duration of a timer,
- wherein the spoofed data transmissions include messages to keep links associated with the UAV active, and
- wherein the spoofed data transmissions include an address of the UAV to indicate that the spoofed data transmissions originated from the UAV instead of the controller.
A network device for managing a wireless connection of an Unmanned Aerial Vehicle (UAV), comprising:
- a processor;
- a memory coupled to the processor, wherein the memory includes one or more instructions that when executed by the processor cause the network device to:
- detect a handover condition for the UAV within a wireless network, wherein the UAV is connected to a source cell in the wireless network when the handover condition is detected;
- determine, in response to detecting the handover condition, a target cell in the wireless network based on a flight path of the UAV;
- and
- initiate a handover of the UAV from the source cell to the target cell,
- wherein initiating the handover further comprises:
- spoofing data transmissions on behalf of the UAV for the duration of a timer,
- wherein the spoofed data transmissions include messages to keep links associated with the UAV active, and
- wherein the spoofed data transmissions include an address of the UAV to indicate that the spoofed data transmissions originated from the UAV instead of the controller.
