Of course, the base station may also be a base station that applies other wireless modulation techniques besides the LoRa base station, such as a base station that applies FLRC and FSK, and the wireless frame may be a wireless frame based on FLRC and FSK.

The base stations can form Mesh (wireless Mesh network), such as LoRa Mesh, and the base stations in the Mesh can be directly interconnected to form a network without depending on a router or an exchanger of a third party, and the base stations can not only provide access service for the nodes, but also complete the routing function.

When a first base station serving as a serving base station wants to distribute a service provided by the first base station to other base stations, the first base station may send a first wireless frame to the base stations within a wireless signal coverage of the first base station, and the first wireless frame may be used to distribute the service provided by the first base station to other base stations, for example, the first wireless frame is a service route probe request wireless frame, and specifically, the first wireless frame may be sent in a broadcast manner.

The base stations can form a Mesh (wireless Mesh network), such as a LoRa Mesh, and the base stations in the Mesh can be directly interconnected to form a network without depending on a router or an exchanger of a third party, so that the base stations can not only provide access service for the nodes, but also complete a routing function.

When a node in the network wants to access a service provided by the serving base station, for example, an LoRa terminal in the LoRa Mesh or a gateway wants to access the service provided by the serving base station, it may send a second radio frame to the base station in the located area, where the second radio frame may be used to request the service from the serving base station.

The second radio frame may include base station information of a first base station as a target base station (the first base station is a serving base station), base station information of a third base station as a next-hop base station (the base station information of the next-hop base station may be updated with forwarding of the response frame, which may be obtained by querying a preset routing table), and target data (data to be processed by the serving base station, such as communication data).

Step 402, the third base station determines the base station information of the second base station according to the routing information aiming at the first base station in the preset routing table; the routing information of the first base station is that the third base station receives a first wireless frame sent by the first base station through the second base station, and the first wireless frame is added or updated in a preset routing table according to the first wireless frame, wherein the first wireless frame comprises base station information of the first base station serving as a service base station, base station information of the second base station serving as a sending base station, and current hop count information of the first wireless frame.

Since the first base station serving as the serving base station issues the service, the third base station has previously recorded the routing information for the first base station in the preset routing table, and after receiving the second wireless frame, the third base station may perform query in the preset routing table, so as to determine the base station information of the next-hop base station from the third base station to the first base station, that is, the base station information of the second base station serving as the next-hop base station.

In step 403, the third base station updates the base station information of the next-hop base station in the second wireless frame to the base station information of the second base station, and sends the second wireless frame to the second base station, so as to send the second wireless frame to the first base station through the second base station.

After determining the next-hop base station, the third base station may update the base station information of the next-hop base station in the second wireless frame to the base station information of the second base station, and may then send the second wireless frame to send the second base station to the next-hop base station, that is, the second base station.

After receiving the second wireless frame, since the second base station has previously recorded the routing information for the first base station in the preset routing table, the second base station may query in the preset routing table to determine the base station information of the next-hop base station from the second base station to the first base station, that is, the base station information of the first base station serving as the next-hop base station, update the next-hop base station information in the second wireless frame, and may send the second wireless frame to the first base station serving as the serving base station.

In the embodiment of the invention, by receiving a sent second wireless frame, the second wireless frame includes base station information of a first base station as a target base station, base station information of a third base station as a next-hop base station, and target data, then the base station information of the second base station can be determined according to routing information of the first base station in a preset routing table, the base station information of the next-hop base station in the second wireless frame is updated to the base station information of the second base station, and the second wireless frame is sent to the second base station, so that the second wireless frame is sent to the first base station through the second base station, thereby realizing transfer transmission of wireless signals among the base stations, enabling the wireless signals to be transmitted outside the coverage range of a single base station, and expanding the application scene of the internet of things.

step 501, a third base station receives a second wireless frame; the second wireless frame comprises base station information of a first base station serving as a target base station, base station information of a third base station serving as a next hop base station and target data;

when a node in the network wants to access a service provided by the serving base station, for example, an LoRa terminal in the LoRa Mesh or a gateway wants to access the service provided by the serving base station, it may send a second radio frame to the base station in the area where the node is located, and the second radio frame may be used to request the serving base station for the service.

Step 502, when the third base station does not detect other base stations which provide services required by the second wireless frame, or the hop count from the third base station to other base stations is greater than or equal to the hop count from the third base station to the first base station, determining the base station information of the second base station according to the routing information aiming at the first base station in the preset routing table; the routing information of the first base station is that a third base station receives a first wireless frame sent by a second base station, and the first wireless frame is added or updated in a preset routing table according to the first wireless frame, wherein the first wireless frame comprises base station information of the first base station serving as a service base station, base station information of the second base station serving as a sending base station and current hop count information of the first wireless frame;

In step 503, the third base station updates the base station information of the next-hop base station in the second wireless frame to the base station information of the second base station, and sends the second wireless frame to the second base station, so as to send the second wireless frame to the first base station through the second base station.

Moreover, when a plurality of serving base stations exist in the network, the serving base station closest to the network can be selected autonomously in the network, thereby improving the efficiency of network communication and reducing the loss.
