Unmanned aerial vehicle (UAV)
A procedure in updating information of a connection in associating an Unmanned Aerial Vehicle (UAV) with a UAV controller to establish the connection is not clarified. For the connection for performing communication of the UAV, a user plane resource is to be activated. The UAV updates stored identification information and IP address of the UAV controller, based on reception, from a network, of a PDU session modification command message including identification information and IP address of the UAV controller. The UAV, in a case of establishing a PDU session that provides a QoS flow for performing Command and Control (C2) communication, transmits and/or receives information for establishing an Always-on PDU session to and/or from a network.
1. A UAV comprising:
transmission and reception circuitry; and
a controller,
in a case that the transmission and reception circuitry receives, from a network, a PDU session modification command message including first identification information, the controller forwards the first identification information to an upper layer, and
the first identification information is identification information of the UAV.
2. The UAV of claim 1 , wherein
the transmission and reception circuitry receives the PDU session modification command message including second identification information and/or third identification information;
the second identification information is identification information of a new UAV controller, and
the third identification information is an IP address of a new UAV controller.
3. A communication control method performed by a UAV, the communication control method comprising:
receiving, from a network, a PDU session modification command; and
in a case that the PDU session modification command message includes first identification information, forwarding the first identification information to an upper layer, wherein
the first identification information is identification information of the UAV.
