As shown in FIG. 1A, the ad hoc network transmission resource management system 10 includes a first terminal 101 and at least one station The first terminal 101 maintains a communication connection with the first site 102 of the at least one site. When the user terminal starts the ad-hoc network transmission resource management system, the first terminal 101 will inquire about the location of the nearby first site 102 Speaking of the spectrum situation in the area near the first station 102, the first station 102 will provide the first terminal 101 with spectrum information of the current environment or directly provide recommended communication frequency points, and the terminal will communicate with other terminals in a long-distance ad hoc network At this time, the communication frequency points will be selected first based on the obtained spectrum information. The first station 102 may be a gateway device such as a base station or a router. In addition, as shown in FIG. 1B, the ad-hoc network transmission resource management system provided by the embodiment of the present application may further include a server 103, and the first terminal 101 and the first site 102 may realize a communication connection through the server 103.

As shown in the figure, the communication method includes:

S201: The first terminal sends an ad-hoc network spectrum query request to the first station within the signal coverage.

Wherein, the first terminal may be a terminal device with ad hoc network communication capabilities, and the first terminal may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or connected to wireless devices with ad hoc network communication functions. Other processing equipment of the modem, as well as various forms of user equipment (User Equipment, UE), mobile station (Mobile Station, MS), electronic equipment (terminal device), and so on. For example, the first terminal may be a smart phone, the first terminal may also be a smart phone, the first terminal may also be a tablet computer, etc., which are not specifically limited.

Wherein, the ad hoc network may specifically be a low-power wide area network (LPWA) supporting long-range radio (Long Range Radio, LoRa), Sigfox, Bluetooth and other protocols, or it may support various types of communications in 3GPP. The mobile communication network of the protocol is not uniquely limited here. The signal coverage area refers to the signal coverage area of the communication module (for example: wireless communication module) supporting the ad hoc network communication capability of the first terminal.

Wherein, step S201 may occur before the first terminal establishes a communication connection with other terminals; step S201 may occur after the first terminal establishes a communication connection with other terminals, and further, when step S201 occurs at the first terminal After the terminal establishes a communication connection with other terminals: the condition for triggering step S201 may be when it is detected that the communication quality of the current communication between the first terminal and other terminals reaches the triggering condition, for example, the data transmission rate is lower than the preset rate, And so on, it is not specifically limited; the condition for triggering step S201 may be a preset time interval.

The resource description information may also be directly packaged and sent to the first terminal by the first site without being screened, and step S203 may be that the first terminal indirectly determines to create the first terminal according to the resource description information. The first transmission resource of the ad hoc network, that is, step S203 may be that the first terminal filters out the target description information related to the first transmission resource used to create the first ad hoc network from the resource description information, The first transmission resource used to create the first ad hoc network is determined according to the target description information.

Wherein, the quality of the communication link is less than the preset quality may be that the data transmission rate of the communication link is less than the preset transmission rate, and the communication link quality is less than the preset quality, or it may be that the communication link transmits data. The packet loss rate is greater than the preset packet loss rate, etc., which are not specifically limited; wherein, the communication link quality parameter may be a quality score, and the quality score may be calculated according to the transmission rate of the communication link, the packet loss rate, etc. The score obtained; the preset time interval can be 3s, 5s, 10s, 1min, 5min, 10min, etc., and is not specifically limited.
