The balloon unmanned aerial vehicle layer comprises a balloon unmanned aerial vehicle 12, an airship unmanned aerial vehicle and the like. The common unmanned aerial vehicle layer comprises an unmanned aerial vehicle 13. The terrestrial wireless network includes base stations 14. Here, wireless communication may be implemented between the base station 14 and the drone 13. Wireless communication can be achieved between the drone 13 and the balloon drone 12. Wireless communication can be achieved between the balloon drone 12 and the communication satellite 11. Wireless communication can also be achieved between the drones 13. In this example, the drone 13 may be used as a terminal and controlled by the base station 14, or the drone 13 may be used as a base station to serve the terminal, but the single drone is used as a base station, so that the network coverage is limited.

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

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

In one embodiment, a plurality of communication nodes communicate using a sidelink protocol.

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

In one embodiment, the communication node may be an unmanned aerial vehicle controlled by a control device operated by a radio remote control device or an automatic running program.

Here, the communication node may be one of: unmanned aerial vehicle, aircraft, satellite, low orbit satellite, hot air balloon, on-vehicle 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, or the like.

In one embodiment, the communication nodes comprised by 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 information such as names, hardware addresses, and communication functions of the 3 communication nodes. Here, the communication function may include a communication node as at least one of: relay, base station. Here, the communication function of the communication node having the relay may be to have an amplification function of realizing a wireless signal. The signal coverage of the virtual base station group can be enlarged by amplifying the wireless signal. Here, the communication nodes may each have a function as a terminal. Here, the communication node may report its own communication function information in advance. Referring to table one, a maintenance list of a virtual base station group including 3 communication nodes is shown.

List one

Communication node name information	Hardware address information	Communication function information
			Communication node A	AC112cdccd22	Terminal, relay
Communication node B	Ccdd325dd00	Terminal, 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 querying the maintenance list. For example, the hardware address of the communication node a is "AC112cdccd22", 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, or 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 body that maintains the list may be provided in the base station. For example, the maintenance body for maintaining the list may be provided in a base station and/or other types of relay nodes and/or core network elements of an existing cellular mobile communication. Here, the body of the maintenance list may also exist alone as one communication entity. For example, the maintenance list is maintained by a multi-communication node coordination gateway node, which is provided in the network as a single communication entity.

In one embodiment, each virtual base station group may contain a plurality of virtual base stations in the virtual base station group. One communication node in the virtual base station group may be a single virtual base station and have 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 not overlap with each other. For example, when the functions implemented by a plurality of communication nodes do not overlap with each other, each communication node may implement a certain function of the base station, respectively. For example, the first communication node performs a signal receiving 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; and the fourth communication node completes the management function of the base station. When the functions implemented by a 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 may also include only virtual base stations where a single communication node performs the base station function. For example, the virtual base station group includes only a third virtual base station constituted by D communication nodes and a fourth virtual base station constituted by E communication nodes. The virtual base station group may also include only virtual base stations in which a plurality of communication nodes cooperate to realize a base station communication function. For example, the virtual base station group includes only the fifth base station composed of the F communication node and the G communication node.

In one embodiment, communication may be implemented between groups of virtual base stations. For example, if the communication nodes in the communication node system constitute a virtual base station group a, a virtual base station group B, and a virtual base station group C, communication can be implemented between the virtual base station group a, the virtual base station group B, and the virtual base station group C.

In one embodiment, communication may be implemented between virtual base stations in the same virtual base station group.

In the embodiment of the disclosure, the virtual base stations in the virtual base station group can provide the access service of the cellular mobile communication network for the user equipment. Meanwhile, each communication node at each location can cover a space area. Because the virtual base station group is composed of a plurality of communication nodes, the plurality of communication nodes can cover a wider space range than a single communication node, so that the virtual base station group has a wider network communication coverage range, and the access service requirement under a wide network coverage range scene is met. And the communication nodes with different functions can be complemented in function when the virtual base station group is built, so that the communication nodes are better utilized.
