The technical solutions in the embodiments of the present invention will be described clearly and in detail below in conjunction with the accompanying drawings in the embodiments of the present invention.

In the embodiment of the present invention, a communication control method and related equipment are provided, which can effectively realize short-distance direct communication between terminal devices, thereby reducing the complexity of communication between terminal devices. In the embodiment of the present invention, the first terminal device and the second terminal device may be unmanned aerial vehicles, unmanned vehicles, etc., which are not limited in the embodiment of the present invention. Detailed descriptions are given below.

Please refer to FIG. 1, which is a schematic diagram of a communication architecture provided by an embodiment of the present invention. The communication system includes a terminal device and a network. As shown in FIG. 1, the communication system may include a network 101 and one or more terminal devices 102.

The form and quantity of the network and terminal devices shown in FIG. 1 are only for example, and do not constitute a limitation to the embodiment of the present application.

The terminal device in this application is a device with a wireless communication function. The terminal device can be a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, and an industrial control (industrial control). The wireless terminal in the self-driving (self-driving), the wireless terminal in the remote medical (remote medical), the wireless terminal in the smart grid (smart grid), the wireless terminal in the smart home (smart home), etc. , It can also be in-vehicle devices, wearable devices, etc. with wireless communication capabilities.

In this application, the terminal device 102 can broadcast its own device type information, and the terminal device 102 can also monitor the device device type information, and then determine whether to establish a near field communication connection based on the acquired device type information and the monitored device type information. Obtaining a match between the broadcasted device type information and the monitored device type information, the two terminal devices establish short-range communication, thereby realizing the communication between the terminal device and the terminal device, and reducing the complexity of the communication between the terminal devices.

In this application, taking the drone as an example, the drone UAV1 can establish a PDU session by accessing the network, and after the drone is connected to the network, it can communicate with the outside world. The drone management center can control the behavior of the drone through the network, and the drone controller can also establish a connection with the drone management center UTM through the network to obtain information about the drone or communicate with the drone. The UTM here can be responsible for drone registration, location tracking, and so on. At the same time, the UAV controller can directly control the UAV through the C2 port, as shown in Figure 2a, which is the process in which the UAV communicates with the outside world through the network, that is, realizes the connection and interaction with the network. At the same time, when the drones need to communicate in close range, a communication connection can be established, and then information can be exchanged. The drone UAV1 broadcasts its own device type information during the flight. The device type information indicates that the device type of UAV 1 is a drone. When another drone UAV2 enters the vicinity of the drone UAV1 during the flight, You will get the device type information broadcast by UAV1, knowing that UAV1 is a drone, and the device type information of UAV2 is used to indicate that the monitored device type is also a drone, then the device type indicated by the device type information broadcast by UAV1 and UAV2 monitoring The device type indicated by the device type information matches the device type.

Among them, the terminal device 102 connects to the AN (Access Network) through the Uu port to connect to the access layer to exchange access layer messages and wireless data transmission. The terminal device can also communicate with the AMF (Access and Mobility Management Function) through the N1 port. Access and mobility management functions) make NAS (None Access Stratum, non-access stratum) connections and exchange NAS messages. UPF (User Plane Function, User Plane Function) is a user plane function in the core network. It transmits data to an external data network through the N6 interface, and transmits data to the AN through the N3 interface. After the terminal device accesses the 5G network through the Uu port, it establishes a PDU (Protocol Data Unit) session data connection from the terminal device to the UPF under the control of the SMF (Session Management Function) to perform data transmission.

It should be noted that the device type information detected by UAV2 here may not be the same device type as UAV2, but may be a terminal device that detects other device types. For example, the type of device that UAV2 can monitor is an unmanned vehicle to achieve close-range direct communication between different terminal devices. .

In this application, the establishment of the terminal device 102 and the terminal device 102 requires the help of a policy control function entity, where the policy control function entity may be a policy control function entity in the network, such as the 5G policy control function entity PCF, 4G Policy control function entity PCRF, etc.; it may also be a policy control function entity specifically configured by the network for communication between terminal devices 102. The policy control function entity not only configures network-side wireless parameters for the terminal device 102, but can also instruct the terminal device 102 to broadcast device type information, and can also configure the terminal device with monitored device type information.

Please refer to FIG. 3, which is a schematic flowchart of a communication control method according to an embodiment of the present invention. The method of this embodiment is applied to the above-mentioned communication system. The method is applied to the first terminal device and includes the following steps:

301. Acquire first device type information broadcast by a second terminal device, where the first device type information is used to indicate a device type of the second terminal device.

Specifically, when the first terminal device enters the range where the second terminal device broadcasts the first device type, it can obtain the first device type information broadcast by the second terminal device.

Wherein, the first device type information includes the device type of the second terminal device or a code used to indicate the device type of the second terminal device. The equipment types of UAVs can be divided into transportation UAVs, public safety UAVs, or high-speed/medium-speed/low-speed operation UAVs and so on. The device type code of the second terminal device may be generated when the terminal device is out of the field, or may be pre-configured by the management center of the corresponding terminal device, or configured by the policy control function entity. For example, assuming that the device type code can be pre-configured, such as a drone, the drone management center will configure the device type code for the drone when the drone is registered, such as setting "01" to represent "drone ".

It should be noted that the code here can be an identification, a number, etc., which will not be repeated here.

In some implementations, the first device type information can be used to indicate the device type of the second terminal device itself. Optionally, the first device type information can also be used to indicate the code of the device type of the second terminal device. The code of the device type can know the device type.

302. Determine, according to the first device type information, whether to establish short-range direct communication with the second terminal device.

Wherein, the short distance here may mean that the first terminal device can obtain the first device information broadcast by the second terminal device.

In some implementation manners, before the first terminal device determines whether to establish short-range direct communication with the second terminal device according to the first device type information, the first terminal device obtains the second device type information of the first terminal device, and the second terminal device The device type information indicates the device type monitored by the first terminal device. Wherein, the second device type information includes the device type of the first terminal device or a code used to indicate the device type of the first terminal device. The code of the device type of the first terminal device may also be determined by the above-mentioned method of generating the code of the device type of the second terminal device.

In some implementations, the second device type information may include the device type itself monitored by the first terminal device. Optionally, the second device type information may also include a code for indicating the device type monitored by the first terminal device, that is, In the process of monitoring, the code representing the device type is directly monitored, and the device type that needs to be monitored can be known through the code of the device type.

In some feasible manners, the second device type information is pre-configured, or the second device type information is obtained from the policy control function entity. Among them, the policy control function entity may be the PCF in the 5G core network, or the terminal device policy control function specifically set for the terminal device in the 5G core network, and so on. The pre-configured second device type information may be directly configured through the management center of the first terminal device or when the first terminal device is produced, and so on.

It should be noted that the policy control function entity here is not only limited to the policy control function in 5G or the policy control function specifically set for terminal equipment in the 5G core network, but also includes the policy control function and other communications in all other communication systems. The system network specifically sets the policy control function for the terminal equipment.

Further, after the terminal device obtains the second device type information of the first terminal device, it can determine whether to establish short-range direct communication according to the first device type information and the second device type information.

Further, the first terminal device may determine whether the device type indicated by the first device information and the device type indicated by the second device type information match, if the device type indicated by the first device information and the device type indicated by the second device type information If it matches, the first terminal device and the second terminal device establish short-range direct communication. For example, if both the first terminal device and the second terminal device are drones, the second device type information of the first terminal device is used to indicate that the monitored device type is a drone, and the first device of the second terminal device The type information is used to indicate that the broadcast device type is also a drone, and the first device type information matches the indicating device type in the second device type information, and the two drones determine to establish short-range direct communication.

Or alternatively, if the first device type information is used to indicate the code of the device type of the second terminal device, and the second device type information is used to indicate the code of the device type monitored by the first terminal device, if the first terminal device type information is The code of the indicated device type matches the code of the device type indicated by the second device type information, and the first terminal device determines to establish short-range direct communication with the second terminal device. For example, the code for the device type indicated by the first device type information is 02, and the code for the second device type information used to indicate the monitored device type is also 02, then the first terminal device determines to establish short-range direct communication with the second terminal device .

In some implementations, the first device type information is used to indicate the device type of the second terminal device, and the second device type information is used to indicate the device type monitored by the first terminal device. The monitored device type here may be different from the first device type. The device types of the terminal devices are the same. For example, the second terminal device is a drone, the first terminal device is an unmanned car, the first device type information is used to indicate that the second terminal device is a drone, and the second device type information is used For indicating that the device type of unmanned vehicle monitoring is a drone, when the first terminal device detects that the device type is a drone, it is found that the device type indicated by the first device type information matches the device type indicated by the second device type information , The first terminal device determines to establish short-range direct communication with the second terminal device. In this way, communication between different terminal devices can be realized.

In some feasible embodiments, after the first terminal device determines to establish short-range direct communication with the second terminal device, the first terminal device sends a communication request to the second terminal device, and the communication request carries the device type of the first terminal device Information, the device type information is used to indicate the device type of the first terminal device or the code used for the device type of the first terminal device, and the second terminal device needs to monitor the device type information and the received device of the first terminal device according to the device type information that it needs to monitor The type information is matched. If the matching is successful, the first terminal device and the second terminal device establish a short-distance direct communication channel, and then they can send their respective identifications, operating conditions, and so on.

In some feasible embodiments, the first terminal device is a drone, and the second terminal device is also a drone. After the first terminal device and the second terminal device establish short-range direct communication, the first terminal device (without The human-machine) can then send its own drone identification, flight information, etc. to the second terminal device (drone), so that both parties can adjust the flight direction to avoid collision. Among them, the flight information can be path information, flight speed, and so on.

Optionally, the first terminal device is a drone, and the second terminal device is also a drone. After the first terminal device establishes short-range direct communication with the second terminal device, the first terminal device (drone) receives The UAV identification, flight information, etc. sent by the second terminal device (UAV), so that both parties adjust the flight direction to avoid collision. Among them, the flight information can be path information, flight speed, and so on.

Optionally, the first terminal device is a drone, and the second terminal device is also a drone. After the first terminal device and the second terminal device establish short-range direct communication, the first terminal device (drone) can Send its own drone identification, flight information, etc. to the second terminal device (drone). The second terminal device also sends its own drone identification, flight information, etc. to the first terminal device, so that both parties adjust the flight direction to avoid collision. Among them, the flight information can be path information, flight speed, and so on.

In some feasible embodiments, when the device type indicated by the device type information monitored by multiple terminal devices matches the device type broadcast by the second device type information, the terminal device and the second device type that are closer to each other are selected from the multiple terminal devices. The second terminal device establishes short-range direct communication, or the second terminal device can establish short-range direct communication with multiple terminal devices at the same time.

In the embodiment of the present invention, the first terminal device obtains the first device type information broadcast by the second terminal device, where the first device type information is used to indicate the device type of the second terminal device, and then it is determined whether or not according to the first device information Establish a short-range communication connection with the second terminal device, thereby realizing communication between the terminal device and the terminal device, and reducing the complexity of communication between the terminal devices.

For example, taking the drone as an example, the drone UAV1 establishes a PDU session through the network, and then interacts with the control management center UTM through the network. UAV1 performs flight registration with the UTM, obtains the UTM registration authorization to obtain the flight permission, and then the UTM sends The policy control function of the 5G core network sends a message that the UAV1 registration is complete, telling the policy control function entity that it can configure the wireless parameters of the UAV1 on the network side, and the message carries the device type information of the UAV1. The policy control function will configure UAV1 with relevant network-side wireless parameters (broadcast frequency bands, etc.), where the configuration information includes wireless configuration parameters and UAV1 device type information. Then the policy control function sends the configuration information to the access and mobility management function entity AMF, and the AMF packs the configuration information and carries it in NAS signaling and sends it to UAV1. Then UAV1 broadcasts according to the device type information in the configuration information. The device type information indicates that the device type of UAV1 is a drone. When the second drone UAV2 enters the broadcast range of UAV1, it receives the device type information sent by UAV1. Then UAV2 matches the received device type information with the device type information it monitors. Assuming that the device type information of UAV2 is used to indicate that the device type monitored by UAV2 is a drone, the device type monitored by UAV2 is the same as that broadcast by UAV1. After the matching is successful, UAV2 will establish short-range direct communication with UAV1. After the establishment is successful, the respective path information and speed information can be exchanged, so that the flight behavior can be adjusted to avoid the collision of the two UAVs. The entire UAV realization process is shown in Figure 5.

The notification message informs UAV1 that it can start broadcasting device type information. If the notification message includes the device type information of UAV1, UAV1 starts broadcasting its own device type information.
