Embodiment 1
[0075] The embodiment of this application provides a communication method, such as Figure 4 shown, including:
[0076] 401. A RAN node (referred to as a first RAN node) acquires identification information of a first area.
[0077] Wherein, the service area of the first RAN node includes the first area.
[0078] The first area may be one or more cells. Any cell in the first area may be an air-to-air cell (that is, a cell that provides air wirelesssignal coverage), or a common cell (that is, a non-air-to-air cell).
[0079] 402. The first RAN node broadcasts first indication information to the first area, where the first indication information is used to instruct a terminal device of the first type to enter a connected state or remain connected or enter and maintain a connected state. Correspondingly, the terminal device in the first area receives the first indication information from the first RAN node.
[0080] Wherein, the terminal device of the first type in the embo...
Embodiment 2
[0180] In addition to the method provided in Embodiment 1, this embodiment of the present application also provides a method for instructing a terminal device to maintain a connected state through NAS signaling. The AMF in this method is not directly related to the first AMF in Embodiment 1. see Figure 8 , the method includes:
[0181] 801. The terminal device sends a third message to the AMF, where the third message carries type information of the terminal device.
[0182] Wherein, the third message may be an N1NAS message, such as a registration request (registration request), a service request (service request) and the like.
[0183] 802. If the AMF determines that the terminal device is a terminal device of the first type according to the third message, the AMF sends third indication information to the terminal device, where the third indication information is used to instruct the terminal device to maintain a connected state in the target area. Correspondingly, the ter...

Abstract
The present application provides a communication method and device, which relate to the field of communication technology and are used to solve the problem that the network cannot locate the UAV due to the UAV being in an idle state. The method includes: the access network device acquires identification information of the first area; the access network device broadcasts to the first area a first signal for instructing the terminal device of the first type to enter the connected state or maintain the connected state or enter and maintain the connected state Instructions. The access network device can make the first type of terminal device in the idle state in the first area enter the connected state by broadcasting the first indication information to the first area. When the first type of terminal device is a drone, It can solve the problem that the network cannot locate the drone due to the idle state of the drone.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] Currently, for unmanned aerial vehicles (UAVs), some drones (for example, drones used for agricultural operations or power inspections) do not need to be positioned, while some drones (for example, UAVs that are close to or located in UAV-controlled areas) need to be positioned. When the UAV needs to be positioned, for the UAV in an idle state, the network side cannot detect that the UAV is close to or located in the control area of the UAV, so that the UAV cannot be positioned. Contents of the invention [0003] The embodiments of the present application provide a communication method and device, which are used to solve the problem that the network cannot locate the UAV due to the UAV being in an idle state. [0004] In order to achieve the above purpose, the embodiment of the present appl...
