In this embodiment, the Mesh device may select the serving Mesh gateway device according to at least one of the following manners: when only one Mesh gateway device exists in the Mesh gateway device list, the Mesh gateway device is used as a service Mesh gateway device; when a plurality of Mesh gateway devices exist in the Mesh gateway device list, preferentially selecting a Mesh gateway device with good communication quality with a cloud end as a service Mesh gateway device; when a plurality of Mesh gateway devices exist in the Mesh gateway device list, preferentially selecting a Mesh gateway device with good communication quality with the Mesh device as a service Mesh gateway device; and when a plurality of Mesh gateway devices exist in the Mesh gateway device list, preferentially selecting the Mesh gateway device with a large device identification value as the service Mesh gateway device.

Through the steps, the Mesh device can discover and flexibly select the Mesh gateway device, so that the problems of low reliability, complex processing and large overall communication data volume of a Mesh gateway selection mode in the related technology can be solved, and the effects of improving the communication reliability and reducing the communication data volume and the processing complexity are achieved.

Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.

In this embodiment, a Mesh gateway selection device is further provided, and the device is used to implement the foregoing embodiments and preferred embodiments, and details of which have been already described are omitted. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function. Although the means described in the embodiments below are preferably implemented in software, an implementation in hardware, or a combination of software and hardware is also possible and contemplated.

Fig. 3 is a block diagram of a Mesh gateway selection apparatus according to an embodiment of the present invention, and as shown in fig. 3, the apparatus includes a receiving module 10, a maintaining module 20, and a selecting module 30.

The receiving module 10 is configured to receive an announcement message sent by a Mesh gateway device in a Mesh network.

The maintenance module 20 is configured to maintain a Mesh gateway device list according to the announcement message.

The selecting module 30 is configured to select a Mesh gateway device from the Mesh gateway device list as a Mesh gateway device in communication with a cloud.

It should be noted that, the above modules may be implemented by software or hardware, and for the latter, the following may be implemented, but not limited to: the modules are all positioned in the same processor; alternatively, the modules are respectively located in different processors in any combination.

In order to facilitate understanding of the technical solutions provided by the present invention, the following detailed description will be made with reference to embodiments of specific scenarios.

By way of contrast, two Mesh gateway selection methods commonly used in the prior art will now be briefly described.

Fig. 4 is a flowchart of a Mesh gateway selection method according to the related art, as shown in fig. 4, the flowchart includes the steps of:

step S401, a default Mesh gateway device is preset in the Mesh device.

Step S402, when the Mesh device communicates with the cloud, the information is sent to the default Mesh gateway device.

Step S403, the Mesh gateway device sends the information from the cloud to the Mesh device.

Step S404, when the Mesh gateway device fails, the Mesh device cannot communicate with the cloud.

It can be seen that the above Mesh gateway selection method has the disadvantage of low reliability.

Fig. 5 is a flowchart of another Mesh gateway selection method according to the related art, as shown in fig. 5, the flowchart includes the steps of:

step S501, the Mesh device sends information communicated with the cloud end to the Mesh network in a broadcasting mode, and each piece of information is uniquely identified.

Step S502, after each Mesh gateway device receives the information, the information is forwarded to the cloud.

And step S503, after receiving the information from the Mesh gateway devices, the cloud performs duplicate removal processing according to the unique identifier of the information, and completes the information reception.

Step S504, when any Mesh gateway device fails, the Mesh device may communicate with the cloud through another Mesh gateway device.

As can be seen from the above description, the Mesh gateway selection method in fig. 5 has the disadvantages of complex processing and large overall communication data volume.

Therefore, the embodiment provides a new Mesh gateway selection method, and compared with the Mesh gateway selection methods shown in fig. 4 and 5, the Mesh gateway selection provided by the embodiment can improve the reliability and reduce the communication data volume and the processing complexity.

In this embodiment, when a plurality of Mesh gateway devices exist in a Mesh network, the Mesh devices automatically discover the Mesh gateway devices, and the Mesh devices run a selection algorithm to select an optimal gateway device, and communicate with the cloud through the gateway device. In this embodiment, the Mesh device may determine the optimal gateway device according to parameters such as the communication quality between the Mesh gateway device and the cloud, the communication quality between the Mesh device and the Mesh gateway device, and the like.

In this embodiment, the Mesh device and the cloud communicate in a mode from the Mesh device to the Mesh gateway device and then to the cloud. When a plurality of Mesh Gateway devices exist in the Mesh network, the Mesh device calculates an optimal Mesh Gateway device (Gateway, abbreviated as GW).

Fig. 6 is a flowchart of a Mesh gateway selection method according to an alternative embodiment of the present invention, and as shown in fig. 6, the flowchart of the new Mesh gateway selection method includes the following steps:

step S601, the Mesh gateway device periodically sends an announcement message of the Mesh gateway device in a multicast or broadcast manner.

In this embodiment, the multicast or broadcast announcement message of the Mesh gateway device may include an identifier of the Mesh gateway device, communication quality between the Mesh gateway device and the cloud, and whether the Mesh gateway device is in an offline state.

Step S602, the Mesh device automatically discovers all Mesh gateway devices in the Mesh network.

In this embodiment, the Mesh device may automatically discover all Mesh gateway devices in the Mesh network through the received announcement message.

Step S603, the Mesh device locally maintains a Mesh gateway device list.

In this embodiment, the Mesh device may maintain a local Mesh gateway device list according to the information in the received announcement message. Specifically, the list of Mesh gateway devices may be maintained by: and if the gateway equipment is off-line, deleting the gateway equipment from the gateway equipment list. And if the gateway equipment does not exist in the gateway equipment list, adding the gateway equipment into the list, and starting a gateway equipment failure timer. And if the gateway equipment exists in the gateway equipment list, updating the gateway equipment information if the information changes.

In addition, when the Mesh device maintains the Mesh gateway device list, after the Mesh device receives the announcement message of the gateway device, the Mesh device needs to reset the failure timer of the gateway device regardless of whether the information of the Mesh gateway device changes. And if the failure timer of the Mesh gateway equipment is overtime, deleting the gateway equipment from the gateway equipment list.

Step S604, based on the maintained Mesh gateway device list, the Mesh device calculates the optimal Mesh gateway device through a selection algorithm. When the Mesh device needs to communicate with the cloud, data transfer can be performed through the Mesh gateway device.

In step S605, when the Mesh gateway device list changes, for example, information of the added gateway device, the deleted gateway device, and the gateway device changes, the selection algorithm needs to be run again to reselect the optimal gateway device.

The following describes a selection algorithm of the Mesh gateway device in this embodiment.

In step S604 of the present embodiment, the election algorithm mainly depends on the following parameters: the communication quality between the Mesh gateway device and the cloud, the Mesh gateway device identification and the communication quality between the Mesh device and the Mesh gateway device. When the communication between the Mesh gateway device and the cloud end fails or the quality is degraded, switching can be dynamically completed to provide better communication service, and the gateway device identification is mainly used for the algorithm to generate a result.

In this embodiment, based on the gateway device list, when the selection algorithm is run, the following steps are sequentially performed until the result is generated:

if the gateway device list only has one Mesh gateway device at present, selecting the Mesh gateway device as a gateway device communicated with the cloud;

comparing the communication quality of each gateway device in the gateway device list and the cloud end, and selecting the good-quality Mesh gateway device as the gateway device communicated with the cloud end;

comparing the communication quality of the Mesh equipment and the gateway equipment in the gateway equipment list, and selecting the good-quality Mesh gateway equipment as the gateway equipment for communicating with the cloud;

and comparing the device identification of each Mesh gateway device in the gateway device list, and selecting the Mesh gateway device with a large identification value as the gateway device communicated with the cloud.

In this embodiment, the communication quality between the Mesh device and the gateway device may be classified into quality classes according to parameters such as round trip delay and hop count of the packet between the Mesh device and the gateway device, for example, the quality classes may be classified into the following five classes: unusable, worse, medium, better, excellent.

Similarly, the communication quality between the Mesh gateway device and the cloud may also be classified into quality classes according to parameters such as round-trip delay and hop count of the packet between the Mesh gateway device and the cloud, for example, the quality classes may be classified into the following five classes: unusable, worse, medium, better, excellent.

In this embodiment, the Mesh device selects the optimal Mesh gateway device through the selection algorithm, and when the Mesh device communicates with the cloud, the Mesh device only needs to communicate with the cloud through the optimal Mesh gateway device without performing other complex processing (e.g., concurrent operation). In addition, because only one Mesh gateway device provides cloud communication service, the whole communication data volume cannot be increased along with the increase of the Mesh gateway devices, and the cloud does not need to perform other complex processing (such as concurrent sending and selective receiving operations). Moreover, when the Mesh gateway device providing the data communication service breaks down, the Mesh device can calculate a new optimal Mesh gateway device in time, so that the communication continuity is ensured, and the reliability is improved. Finally, through parameters such as the communication quality between the Mesh gateway device and the cloud, the communication quality between the Mesh device and the Mesh gateway device and the like, the Mesh device can dynamically select the best Mesh gateway device, and a better communication guarantee can be provided.
