Wireless communication between the drone 13 and the balloon drone 12 may be achieved. Wireless communication between the balloon drone 12 and the communication satellite 11 may be achieved. Wireless communication between the drones 13 can also be realized. In this example, the drone 13 may serve as a terminal and be controlled by the base station 14, or the drone 13 may serve as a base station to provide a service to the terminal, but the single drone serves as a base station, and the network coverage is relatively limited.

As shown in fig. 2, an embodiment of the present disclosure provides a communication method, applied in a gateway node, including the following steps:

step S21, forming a virtual base station group by a plurality of communication nodes, wherein the plurality of communication nodes communicate with each other by using the first protocol.

In one embodiment, a sidelink protocol is utilized for communication between a plurality of communication nodes.

In one embodiment, the virtual base station group is used for the user equipment to access the cellular mobile communication network.

In one embodiment, the communication node may be an unmanned aerial vehicle controlled by a radio remote control device operated or programmed to operate automatically.

Here, the communication node may be one of: unmanned aerial vehicle, aircraft, satellite, low orbit satellite, balloon, vehicle mounted terminal, multi-functional terminal, ground basic station. Here, the user equipment may be a water meter, an electricity meter, a mobile terminal, a communication node, an environment detection sensor, and the like.

In one embodiment, the communication nodes included in the virtual base station group may be maintained by maintaining a list. The maintenance list may contain information of the communication nodes in the virtual base station group. For example, if the virtual communication node group includes 3 communication nodes, the maintenance list may include names, hardware addresses, communication functions of the 3 communication nodes, and other information. Here, the communication function may include a communication function of the communication node as at least one of: relay, base station. Here, the communication function in which the communication node has the relay may be a function of realizing amplification of a wireless signal. The signal coverage of the virtual base station group can be enlarged by amplifying the wireless signals. Here, it should be noted that the communication nodes may have a function as a terminal. Here, the communication node may report its communication function information in advance. Referring to table one, a maintenance list of a virtual base station group including 3 communication nodes is shown.

Watch 1

Communication node name information	Hardware address information	Information of communication function possessed
			Communication node A	AC112cdccd22	Terminal and relay
Communication node B	Ccdd325dd00	Terminal and relay
			Communication node C	TDDUU36248	Terminal, relay, and base station

The information of each communication node in the virtual base station group can be obtained by inquiring the maintenance list. For example, the hardware address of the communication node a is "AC 112cdccd 22", and the communication node a has a communication function as a terminal and a relay. Here, the communication node information in the virtual base station group may be dynamically added, deleted, changed, and the like. For example, the information of the communication node a is deleted and the information of the communication node D is newly added.

In one embodiment, the maintenance agent maintaining the list may be provided in the base station. For example, the maintenance subject of the maintenance list may be provided in a base station and/or other type of relay node and/or core network element of the existing cellular mobile communication. Here, the main body of the maintenance list may exist as one communication entity alone. For example, the maintenance list is maintained by a multi-communication node coordinating gateway node, which is provided as a single communication entity in the network.

In one embodiment, in the virtual base station groups, each virtual base station group may include a plurality of virtual base stations. One communication node in the virtual base station group can be independently used as a virtual base station and has the communication and management functions of the base station. Wireless communication may be implemented between the communication nodes.

In another embodiment, in the virtual base station group, a plurality of communication nodes may form a virtual base station, and functions implemented by the plurality of communication nodes may overlap or may not overlap with each other.

For example, the first communication node performs a signal reception function of the base station; the second communication node completes the signal sending function of the base station; the third communication node completes the signal modulation function of the base station; the fourth communication node completes the management function of the base station. When the functions implemented by the plurality of communication nodes overlap, the plurality of communication nodes may together implement a certain function of the base station.

The virtual base station group can also comprise only virtual base stations which are cooperatively used by a plurality of communication nodes to realize the communication function of the base station.

For example, the communication nodes in the communication node system form a virtual base station group a, a virtual base station group B, and a virtual base station group C, and communication among the virtual base station group a, the virtual base station group B, and the virtual base station group C can be achieved.

In one embodiment, the first information of the second alternative communication node in the virtual base station group may be acquired periodically. Here, the first information of the second candidate communication nodes in the virtual base station group may be sequentially acquired according to the number of the second candidate communication nodes in the virtual base station group.

wherein the third preset condition includes at least one of: the transmitting power is larger than a fifth set threshold, the distance between the transmitting power and the reference communication node is smaller than a sixth set threshold, and the function of setting is achieved.

In one embodiment, the fifth setting threshold may be set according to the signal coverage requirement of the virtual base station. For example, when the desired signal coverage is the first signal coverage, a smaller fifth set threshold may be set. When the required signal coverage is the second signal coverage, a larger fifth set threshold may be set. Wherein the first signal coverage is greater than the second signal coverage.

In one embodiment, the sixth setting threshold may be set according to the signal coverage requirement of the virtual base station. For example, when the desired signal coverage is the first signal coverage, a larger sixth set threshold may be set. A smaller sixth set threshold may be set when the desired signal coverage is the second signal coverage. Wherein the first signal coverage is greater than the second signal coverage.

In one embodiment, the function having the setting may be that the third alternative communication node has the communication function as the base station set. The third candidate communication node may report the functions it has in advance. For example, the functions of a base station, a relay, and a terminal.

Here, adding the third candidate communication node meeting the third preset condition to the virtual base station group can increase the number of communication nodes in the virtual base station group, and improve the signal coverage capability and the communication processing capability of the virtual base station group.
