Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without making any creative effort, shall fall within the protection scope of the present invention.

It is noted that relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

The controlled terminal can be unmanned electronic equipment in the operation process, for example, unmanned aerial vehicles, unmanned ships, robots, other equipment, and also can be manned operating equipment needing to receive remote control of other equipment, for example, helicopters and the like. During the operation period of the controlled terminal, if data interaction needs to be performed with a remote operator (for example, the ground operator needs to remotely control the unmanned aerial vehicle or the unmanned aerial vehicle needs to feed back data acquired in real time to the ground operator), communication needs to be achieved by means of a wireless communication technology.

In the related art, a controlled terminal and a remote operator communicate with each other through a fixed and single communication network. Any type of communication network has the problem of limited coverage, and of course, has advantages. For example, the mobile communication network is limited in the coverage area over the air, and thus the signal quality of the mobile communication network is not good over the air. Meanwhile, the mobile communication network has wide ground coverage, so the signal quality of the mobile communication network on the ground is good. In addition, the coverage level of the mobile communication network is different in different places, some areas have good signals, some areas have poor signals, and even some areas cannot use the mobile communication network. As another example, private communication networks signal well in ground-to-air communications. However, the signal in the ground dedicated communication network is poor due to problems such as obstruction by ground obstacles.

Therefore, the communication with the operator may be interrupted for a while due to the change of the communication environment during the operation of the controlled terminal. Further causing problems such as untimely remote control or out of control.

In order to solve the above problem, embodiments of the present invention provide a communication method, apparatus, system and electronic device.

Alternatively, the communication system 200 may include the control terminal 10, the relay terminal 20, and the controlled terminal 30. The control terminal 10, the relay terminal 20, and the controlled terminal 30 communicate with each other. The communication between the controlled terminal 30 and the control terminal 10 in the communication system 200 can be implemented in various ways.

In the embodiment of the present invention, a plurality of communication links exist between the control terminal 10 and the controlled terminal 30. Optionally, the control terminal 10 and the controlled terminal 30 include a first communication link and a second communication link. When the control terminal 10 and the controlled terminal 30 need to communicate with each other, data transmission can be performed by using a first communication link and a second communication link in parallel.

It is to be understood that by a communication link is meant a communication channel between two nodes in a communication network. The communication link mentioned in the embodiment of the present invention may be a communication channel provided between two nodes in one network, or may be a communication channel in which a plurality of networks cooperate between two nodes. For example, the network 1 includes a device a and a device B, and a communication channel 1 provided by the network 1 between the device a and the device B is a communication link between the device a and the device B. For another example, the device B also belongs to the network 2, the network 2 also includes the device C, the network 2 provides a communication channel 2 between the device B and the device C, and the communication channel 1 and the communication channel 2 constitute a communication link between the device a and the device C.

Optionally, the first communication link comprises a mobile communication link. The mobile communication link may be a physical channel between two nodes in a mobile communication network provided by a communication carrier. It will be appreciated that the mobile communications link described above is of a public communications link. The coverage area of the communication system on the ground is wide, and the communication quality is not influenced by the shelters. The second communication link is a communication channel established between the control terminal 10 and the controlled terminal 30 through the relay terminal 20. It is to be understood that the second communication link may be a proprietary communication link established via the relay terminal 20. The coverage area of the system in the air is wide, and the special communication efficiency of the private network is high.

It is to be understood that communication of various communication links is enabled between the control terminal 10 and the controlled terminal 30 in the communication system 200 in order to ensure the communication. The networking mode of the above-described circulator communication system 200 may be any one of the following:

the feasible networking mode is as follows: as shown in fig. 1, the control terminal 10 and the relay terminal 20 communicate with each other through a first network, and the relay terminal 20 and the controlled terminal 30 communicate with each other through a second network. The above-described control terminal 10 and controlled terminal 30 each have the capability of accessing a mobile communication network provided by a communication carrier. In this way, the control terminal 10 and the controlled terminal 30 can communicate with each other not only through the second communication link provided by the first network and the second network in cooperation, but also through the mobile communication link provided by the mobile communication network.

Based on the networking method, the mobile communication network provides a mobile communication link between the control terminal 10 and the controlled terminal 30 as a first communication link. Meanwhile, a first communication sub-link provided by the first network between the control terminal 10 and the relay terminal 20 and a second communication sub-link provided by the second network between the relay terminal 20 and the controlled terminal 30 are used as second communication links, that is, the second communication link is composed of the first communication sub-link and the second communication sub-link.

In some embodiments, the first network may be a mobile hotspot network (WiFi), the second network may be a wireless communication network with a longer communication distance, and may be a local area network or a peer-to-peer network, and different communication technologies may be used with the first network.

In some embodiments, for convenience of operation, the control terminal 10 may be any type of mobile device commonly used by users, such as a mobile phone, a tablet computer, and the like. Just because the control terminal 10 may be any device selected by the user, the hardware structure of the control terminal 10 is not easy to change, and therefore, if it is ensured that the control terminal 10 can simultaneously adopt the mobile communication network and the first network to communicate with the outside, the control terminal 10 may be used as an Access Point (AP) of the first network, and the relay terminal 20 may be used as a Station (STA) to join the first network.

In some embodiments, in order to satisfy a requirement that more slave terminals 40 like the control terminal 10 can join the communication system 200 to achieve communication with the controlled terminal 30, the slave terminals 40 may join the first network As Stations (STAs). It is understood that the control terminal 10 and the slave terminal 40 may be devices of the same type or having the same function, and they are different only in that the corresponding roles in the first network are different, that is, the control terminal 10 is an AP in the first network, and the slave terminal 40 is an STA in the first network.

In the communication system 200 shown in fig. 1, if the control terminal 10 generates control data to be transmitted to the controlled terminal 30 in response to a user operation, the control data is transmitted to the controlled terminal 30 in parallel via a plurality of communication links. Alternatively, the control data is transmitted to the relay terminal 20 through the first communication sub-link while the control data is transmitted to the controlled terminal 30 through the mobile communication link. The relay terminal 20 then transmits the control data to the controlled terminal 30 via the second communication sub-link.

In some embodiments, when the controlled terminal 30 generates the response data that needs to be transmitted to the outside, the response data is transmitted to the control terminal 10 through a plurality of communication links. For example, when the response data is data generated in response to control data transmitted by the mobile communication link, the response data is fed back to the control terminal 10 through the mobile communication link. When the response data is data generated in response to the control data transmitted by the second communication sub-link, the response data is transmitted to the relay terminal 20 through the second communication sub-link, and the relay terminal 20 feeds back the response data to the control terminal 10 through the first communication sub-link.

In some embodiments, when the slave terminal 40 generates control data to be transmitted to the controlled terminal 30 in response to a user operation, the control data is transmitted to the relay terminal 20 through the first network while the control data is transmitted to the control terminal 10 through the first network. Then, the control terminal 10 transmits the control data to the controlled terminal 30 through the mobile communication link, and the relay terminal 20 also transmits the control data to the controlled terminal 30 through the second communication sub-link.

It can be seen that all data arriving from an originating node (e.g., the control terminal 10) to a terminating node (e.g., the controlled terminal 30) is sent in parallel over multiple communication links. Therefore, the coverage advantages of various communication links are fully utilized, and the data delivery rate and the communication quality are improved. For example, when the drone is flying at low altitude, although the second communication link has poor communication quality, the first communication link can ensure high-quality communication. When the unmanned aerial vehicle flies at high altitude, although the first communication link has poor communication quality, the second communication link can ensure high-quality communication.

A feasible networking mode two: as shown in fig. 2, the control terminal 10 and the relay terminal 20 communicate with each other through a first network, and the relay terminal 20 and the controlled terminal 30 communicate with each other through a second network. The transit terminal 20 and the controlled terminal 30 each have the capability of accessing a mobile communication network provided by a communication carrier. In this way, the control terminal 10 and the controlled terminal 30 can communicate with each other not only through the second communication link cooperatively provided between the first network and the second network, but also through the first communication link cooperatively provided between the first network and the mobile communication network.

In the above-described networking scheme, the first network provides a first communication sub-link between the control terminal 10 and the relay terminal 20, and the second network provides a second communication sub-link between the relay terminal 20 and the controlled terminal 30. The mobile communication network provides a mobile communication link between the transit terminal 20 and the controlled terminal 30. Optionally, the first communication sub-link and the mobile communication link form a first communication link. The first communication sub-link and the second communication sub-link form the second communication link.

In some embodiments, the first network may be a mobile hotspot network (WiFi), and the second network may be a local area network with a longer communication distance. The relay terminal 20 may be used as a wireless network Access Point (AP) of the first network, and the control terminal 10 is used as a Station (STA) to join the first network. It is understood that the control terminal 10 may be plural, so as to meet the requirement of controlling the controlled terminal 30 by plural operators.

In the communication system 200 shown in fig. 2, if the control terminal 10 generates control data to be sent to the controlled terminal 30 in response to a user operation, the control data is sent to the controlled terminal 30 in parallel through a plurality of communication links. Alternatively, first, the control terminal 10 transmits the control data to the relay terminal 20 through the first communication sublink. Next, the relay terminal 20 transmits the control data to the controlled terminal 30 through the second communication sub-link and the mobile communication link in parallel.

In some embodiments, after the controlled terminal 30 generates the response data, the response data is transmitted to the control terminal 10 through a plurality of communication links. Alternatively, when the controlled terminal 30 receives the control data transmitted by the mobile communication link, the response data corresponding to the control data is transmitted to the relay terminal 20 through the mobile communication link, and the relay terminal 20 transmits the received response data to the control terminal 10 through the first communication sub-link. When the controlled terminal 30 receives the control data transmitted by the second communication sub-link, the response data corresponding to the control data is transmitted to the relay terminal 20 through the second communication sub-link, and the relay terminal 20 feeds back the response data to the control terminal 10 through the first communication sub-link.

Therefore, the coverage advantages of various communication links are fully utilized, and the data delivery rate and the communication quality are improved. For example, when the drone is flying at low altitude, although the second communication link has poor communication quality, the first communication link can ensure high-quality communication. When the unmanned aerial vehicle flies at high altitude, although the first communication link has poor communication quality, the second communication link can ensure high-quality communication.

The relay terminal 20 may be a remote controller, a ground station, a base station, a wireless gateway, a wireless router, or the like. The second network for communication between the relay terminal 20 and the controlled terminal 30 may be a customized local area network having a long-distance communication capability or a WiFi network, and is not particularly limited herein.

In any of the above networking methods, the relay terminal 20 in the communication system 200 needs to have the capability of communicating in multiple networks and transferring data in different networks.

Therefore, in one embodiment, as shown in fig. 3, the relay terminal 20 includes a first wireless communication module 21, a data conversion module 23, and a second wireless communication module 22. The first wireless communication module 21 and the second wireless communication module 22 are electrically connected to the data conversion module 23, respectively. The first wireless communication module 21 is configured to communicate with the control terminal 10 under the first network. The second wireless communication module 22 is configured to communicate with the controlled terminal 30 under the second network. Of course, the relay terminal 20 may further include a bluetooth communication module 24 and the like.

Optionally, the first network and the second network are prevented from interfering with each other when operating at the same communication frequency. The first operating frequency point of the first network (also the operating frequency point of the first wireless communication module 21) and the second operating frequency point of the second network (i.e. the operating frequency point of the second wireless communication module 22) may be configured to be different frequency points. For example, the first wireless communication module 21 and the second wireless communication module 22 both support ISM 2.4Ghz/5Ghz bands, frequency points may be allocated in the following manner:

in a first mode, a first working frequency point of a first network is determined from an ISM 2.4Ghz frequency band, and a second working frequency point of a second network is determined from an ISM5Ghz frequency band.

In a second mode, the first working frequency point of the first network is determined from the ISM5Ghz frequency band, and the second working frequency point of the second network is determined from the ISM 2.4Ghz frequency band.

And thirdly, determining the first working frequency point of the first network and the second working frequency point of the second network from the ISM5Ghz frequency band or from the ISM 2.4Ghz frequency band. It can be understood that the two select different frequency points in the same frequency band as the working frequency points. Optionally, the second network preferentially selects a frequency point with a lower interference level in the corresponding frequency band as its working frequency point.

It can be understood that, the first operating frequency point and the second operating frequency point may both be preset, but, in order to ensure the communication quality, a frequency point with low interference may be dynamically determined from the corresponding frequency band according to the spectrum environment as the operating frequency point.

In some embodiments, the data conversion module 23 is configured to perform protocol conversion on data received by the first wireless communication module 21 or the second wireless communication module 22. For example, data received by the first wireless communication module 21 from the first network is converted into data transferable by the second network, so that the data can be transmitted to the outside by the second wireless communication module 22 through the second network. The data received by the second wireless communication module 22 from the second network is converted into data transferable by the first network so as to be sent out to the outside by the first wireless communication module 21 through the first network.

In another embodiment, as shown in fig. 4, the relay terminal 20 may include a third wireless communication module 25 and a data conversion module 23. The third wireless communication module 25 is electrically connected to the data conversion module 23. That is, the relay terminal 20 is a device of a single wireless communication circuit on the physical layer. In order to enable the intermediate device to communicate with a plurality of networks at the same time, a first virtual interface and a second virtual interface may be created on the third wireless communication module 25. Optionally, a first virtual interface is used for communicating with the control terminal 10 under the first network, and a second virtual interface is used for communicating with the controlled terminal 30 under the second network. The first virtual interface and the second virtual interface multiplex the same wireless communication circuit (i.e., the third wireless communication module 25). The first virtual interface and the second virtual interface can work in coordination in a time division multiplexing mode.

In some embodiments, the data conversion module 23 is configured to perform protocol conversion on data received by the first virtual interface or the second virtual interface. For example, data received by the first virtual interface from the first network is converted into data transferable by the second network, so that the data can be sent out to the outside by the second virtual interface through the second network. And converting the data received by the second virtual interface from the second network into the data which can be transmitted by the first network so as to be sent out to the outside by the first virtual interface through the first network.

In other embodiments, on the basis of the transit terminal 20 shown in fig. 3 or fig. 4, the transit terminal 20 may further include a mobile communication module. The mobile communication module is electrically connected to the data conversion module 23, and the mobile communication module is configured to communicate with the controlled terminal 30 under the mobile communication network. The data conversion module 23 is further configured to perform protocol conversion on the data received by the mobile communication module.

In any of the networking manners, the controlled terminal 30 can be accessed to a mobile communication network provided by a communication carrier, so that the controlled terminal 30 can be integrated with a mobile communication interface, so that the controlled terminal 30 can access the mobile communication network through the mobile communication interface to realize communication with other devices.
