A method comprises: receiving location information of a mobile unit; judging whether the mobile unit is a registered aerial vehicle or an unregistered aerial vehicle; determining whether the mobile unit is in the state of flying based on the location information of the mobile unit; and identifying the mobile unit as a misused aerial vehicle in the condition that the mobile unit is determined as in the state of flying and is judged as the unregistered aerial vehicle. ## Claims ### Claim 1 A method in a base unit, the method comprising: receiving location information of a mobile unit; judging whether the mobile unit is a registered aerial vehicle or an unregistered aerial vehicle, wherein: the mobile unit is judged to be a registered aerial vehicle in response to the base unit having stored information indicating that an air-borne assistance information message, without regard to the content of the air-borne assistance information message, is received prior to receiving the location information; and the mobile unit is judged to be an unregistered aerial vehicle in response to the base unit not having stored information indicating that the air-borne assistance information message is received prior to receiving the location information; determining whether the mobile unit is in the state of flying based on the location information of the mobile unit; and identifying the mobile unit as a misused aerial vehicle in the condition that the mobile unit is determined as in the state of flying and is judged as the unregistered aerial vehicle. ### Claim 2 (depends on 1) The method of claim 1, wherein, in the condition that the mobile unit is judged as the unregistered aerial vehicle, the determining whether the mobile unit is in the state of flying is performed. ### Claim 3 (depends on 1) The method of claim 1, wherein a control node sends the air-borne assistance information to the base unit. ### Claim 4 (depends on 3) The method of claim 3, wherein the control node sends the air-borne assistance information to the base unit no matter whether the air-borne assistance information is empty. ### Claim 5 (depends on 1) The method of claim 1, wherein the air-borne assistance information comprises an expected altitude range, a mobility pattern, path information, an altitude restriction, a speed restriction, or some combination thereof. ### Claim 6 (depends on 1) The method of claim 1, wherein the base unit sends the location information of the mobile unit to a location platform to determine whether the mobile unit is in the state of flying. ### Claim 7 (depends on 1) The method of claim 1, wherein, in the condition that the mobile unit cannot be judged as the registered aerial vehicle, the determining whether the mobile unit is in the state of flying is performed. ### Claim 8 A base unit comprising: a transceiver that receives location information of a mobile unit; a memory; and a processor that: judges whether the mobile unit is a registered aerial vehicle or an unregistered aerial vehicle, wherein: the mobile unit is judged to be a registered aerial vehicle in response to the base unit having stored information in the memory indicating that an air-borne assistance information message, without regard to the content of the air-borne assistance information message, is received prior to receiving the location information; and the mobile unit is judged to be an unregistered aerial vehicle in response to the base unit not having stored information in the memory indicating that the air-borne assistance information message is received prior to receiving the location information; determines whether the mobile unit is in the state of flying based on the location information of the mobile unit; and identifies the mobile unit as a misused aerial vehicle in the condition that the mobile unit is determined as in the state of flying and is judged as the unregistered aerial vehicle. ### Claim 9 (depends on 8) The base unit of claim 8, wherein, the processor, in response to identifying the mobile unit as the misused aerial vehicle, requests a control node to stop serving the mobile unit. ### Claim 10 (depends on 8) The base unit of claim 8, wherein the processor, in the condition that the mobile unit is judged as the unregistered aerial vehicle, determines whether the mobile unit is in the state of flying. ### Claim 11 (depends on 8) The base unit of claim 8, wherein the transceiver receives the air-borne assistance information from a control node. ### Claim 12 (depends on 8) The base unit of claim 8, wherein the processor instructs the transceiver to send the location information of the mobile unit to a location platform to determine whether the mobile unit is in the state of flying. ### Claim 13 (depends on 8) The base unit of claim 8, wherein the processor, in the condition that the mobile unit cannot be judged as the registered aerial vehicle, determines whether the mobile unit is in the state of flying. ### Claim 14 A control node comprising: a transceiver that receives from a base unit a request for stopping serving a mobile unit; and a processor that stops serving the mobile unit upon receiving the request, wherein the transceiver transmits air-borne assistance information to the base unit even if the air-borne assistance information is empty. ### Claim 15 (depends on 14) The control node of claim 14, wherein, the processor judges whether the mobile unit is an unregistered aerial vehicle, and stops serving the mobile unit in the condition that the mobile unit is judged as the unregistered aerial vehicle. ### Claim 16 (depends on 14) The control node of claim 14, wherein the processor instructs the transceiver to transmit location information of the mobile unit to a location platform to determine whether the mobile unit is in the state of flying, and stops serving the mobile unit in the condition that the mobile unit is determined as in the state of flying. ### Claim 17 (depends on 14) The control node of claim 14, wherein the transceiver transmits the air-borne assistance information to the base unit.
