Sweep frequency Ping-Pong measuring method, terminal and server

The invention discloses a sweep frequency Ping-Pong measuring method, terminal and server. The method comprises the steps: a Lora terminal configures related parameters of uplink sweep frequency measuring of this time and sends the related parameters to an application server AS; after receiving a sweep frequency control message, the AS configures an uplink receiving channel of a Lora gateway according to configuration parameters; after acknowledging that the Lora gateway is ready, the AS sends a sweep frequency response message to the Lora terminal; after receiving the response message, the Lora terminal starts a timer to send a Ping message for sweep frequency measuring in an appointed time interval; and after receiving the Ping message from the Lora terminal, the AS sends a Pong messageto the Lora terminal with the same sending parameters as the sent Ping message. According to the method, sweep frequency measuring can be performed on the Lora network to obtain the performance parameters of the network and a
