Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

The terms "first," "second," and the like, herein do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. Likewise, the terms "a" or "an" and the like do not denote a limitation of quantity, but rather denote the presence of at least one. The terms "connected" or "connected," and the like, are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect.

Reference herein to "a module" generally refers to a program or instruction stored in memory that can implement certain functions; reference herein to "a unit" generally refers to a functional structure that is logically divided, and the "unit" may be implemented in pure hardware or a combination of hardware and software.

References herein to "a plurality" means two or more. "and/or" describes an association relationship of an association object, meaning that there may be three relationships, e.g., a and/or B, may represent: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship.

In the related art, an original device and a corresponding shadow device have respective device identifiers and device port information. Typically, after the shadow device is created, the original device can only communicate with the shadow device, and the terminal device can only perform the capabilities provided by the original device by accessing the shadow device. The shadow device can be established in a local network or in a cloud.

If the terminal device broadcasts device discovery information when the shadow device and the original device are in a local network, in a possible implementation manner, the shadow device and the original device both respond to the device discovery message, that is, both feed back respective device identification and device port information to the terminal device. And the terminal device cannot know the relationship between the two, and may select one of them as the control object. However, if the original device is selected, because of the access control, that is, after the shadow device is created, the original device can only communicate with the shadow device, a request sent by the terminal device to the original device is not processed, which results in a problem that the terminal device cannot control the internet of things device after discovering the internet of things device. In another possible implementation, the shadow device may not be able to answer the device discovery message for some reason, while the original device may answer the device discovery message, so the above-mentioned problem may also occur.

When the shadow equipment is built in the cloud, if the terminal equipment broadcasts equipment discovery information, the shadow equipment cannot receive an equipment discovery request broadcast by the terminal equipment, and cannot respond to the equipment discovery information. The original device will answer the message and the above problems will also occur.

The embodiment of the application provides a discovery method and device of Internet of things equipment and terminal equipment, which can be used for solving the technical problems. After the original equipment creates the shadow equipment, the equipment discovery message is sent through the terminal equipment, and the first response message sent by the original equipment is received, and because the first response message comprises the equipment information of the shadow equipment corresponding to the original equipment, the terminal equipment can determine the shadow equipment corresponding to the original equipment according to the first response message, so that the function provided by the corresponding original equipment can be executed through accessing the shadow equipment, and the normal control of the terminal equipment on the Internet of things equipment is ensured.

In summary, in the embodiment of the present application, when the shadow device and the original device are in a local network, the terminal device correspondingly receives response messages of each of the original device and the shadow device by sending a device discovery message, and when discovery resources in the two response messages are matched, determines a one-to-one correspondence between the original device and the shadow device, thereby determining the shadow device corresponding to the original device, and improving the device discovery efficiency.

It should be noted that, when the shadow device and the original device are in a local network, the embodiment shown in fig. 3 may be used to introduce the method for discovering the internet of things device according to the embodiment of the present application; when the shadow device is established in the cloud, the shadow device cannot receive the device discovery message sent by the terminal device, and thus, the steps 308 to 310 may be alternatively implemented as the following steps, as shown in fig. 4:

In step 401, the terminal device sends an information acquisition request to the shadow device indicated by the second device information, where the information acquisition request is used to request to acquire the second discovery resource of the shadow device.

Optionally, in a preset time period after the terminal device receives the first response message sent by the original device, if the second response message of the shadow device is not received, an information acquisition request is sent to the shadow device according to the second device message of the shadow device in the first response message.

Optionally, the second device message includes device identification and/or device port information of the shadow device corresponding to the original device. The terminal device sends an information acquisition request to the access address indicated by the device port information.

In step 402, the shadow device receives an information acquisition request sent by the terminal device.

Correspondingly, after receiving the information acquisition request sent by the terminal equipment, the shadow equipment acquires the second discovery resource of the shadow equipment according to the information acquisition request.

It should be noted that, the relevant description of the second discovery resource of the shadow device may refer to the relevant details in the foregoing embodiments, which are not described herein.

In step 403, the shadow device sends a second discovery resource of the shadow device to the terminal device, where the second discovery resource includes device information of an original device corresponding to the shadow device.

And the shadow equipment responds to the information acquisition request sent by the terminal equipment, namely, the second discovery resource of the shadow equipment is sent to the terminal equipment.

In step 404, the terminal device receives the second discovery resource sent by the shadow device.

Correspondingly, after receiving the second discovery resource sent by the shadow device, the terminal device executes step 311.

It should be noted that, the method for discovering the internet of things device provided in this embodiment is not only suitable for the case that the shadow device is established in the cloud end and cannot respond to the device discovery message, but also suitable for the case that the shadow device and the original device are located in the same local network but the shadow device cannot respond to the device discovery message for some reasons.

In summary, in the embodiment of the present application, when the shadow device is established in the cloud, since the shadow device cannot receive the device discovery message sent by the terminal device, the terminal device actively queries the indicated shadow device according to the second device information in the first response message, thereby obtaining the second discovery resource of the shadow device, so that the shadow device corresponding to the original device can be determined even if the shadow device does not respond, and the accuracy of device discovery is further ensured.

It should be noted that, fig. 3 and fig. 4 provide two possible second discovery resource acquisition manners, on this basis, in one possible implementation manner, after acquiring the first discovery resource in the first response message sent by the original device, the terminal device automatically identifies an establishment location of the shadow device corresponding to the original device, when the shadow device indicated by the establishment location is established in the local network, executes the second discovery resource acquisition manner provided in fig. 3, and when the shadow device indicated by the establishment location is established in the cloud, executes the second discovery resource acquisition manner provided in fig. 4.

Optionally, the first discovery resource further includes a location attribute of the shadow device corresponding to the original device, where the location attribute is used to indicate an establishment location of the shadow device. Schematically, the location attribute of the shadow device corresponding to the original device is represented by an "SDL" parameter.

In one possible implementation, the location attribute of the shadow device is used to indicate that the established location of the shadow device is a local network or cloud. Schematically, the location attribute of the shadow device includes a first attribute value and a second attribute value, where the first attribute value is used to indicate that the shadow device is built in the local network, and the second attribute value is used to indicate that the shadow device is built in the cloud.

For example, the location attribute of the shadow device is string type, and when the location attribute is a first attribute value "local", it indicates that the shadow device is built in the local network, and when the location attribute is a second attribute value "remote", it indicates that the shadow device is built in the cloud.

For another example, the location attribute of the shadow device is a pool type, and when the location attribute is a first attribute value "true", it indicates that the shadow device is established in the cloud, and when the location attribute is a second attribute value "false", it indicates that the shadow device is established in the local network.

In another possible implementation manner, the location attribute of the shadow device is used to indicate the set-up location of the shadow device to be one of the at least two local networks and the cloud end, or to indicate one of the local networks and the at least two cloud ends, or to indicate one of the at least two local networks and the at least two cloud ends.

Optionally, the at least two home networks include n home networks and/or m office networks, where n and m are positive integers.

Optionally, the at least two local networks include i private clouds and/or j public clouds, where i and j are positive integers.

Schematically, the location attribute of the shadow device includes a first attribute value, a second attribute value and a third attribute value, where the first attribute value is used to indicate that the shadow device is built in a local network, the second attribute value is used to indicate that the shadow device is built in a private cloud, and the second attribute value is used to indicate that the shadow device is built in a shared cloud.

Schematically, the location attribute of the shadow device includes a first attribute value, a second attribute value, a third attribute value and a fourth attribute value, where the first attribute value is used to indicate that the shadow device is set up in the first home network, the second attribute value is used to indicate that the shadow device is set up in the second home network, the third attribute value is used to indicate that the shadow device is set up in the first private cloud, and the fourth attribute value is used to indicate that the shadow device is set up in the second private cloud.

It should be noted that, in the embodiment of the present application, only several possible setting manners of the location attribute are schematically illustrated, and the setting manner of the location attribute of the shadow device is not limited in the embodiment of the present application.

Optionally, before performing the step 308 or the step 401, the method further includes: the terminal determines the establishment position of the shadow equipment according to the position attribute of the shadow equipment in the first discovery resource; step 308 is performed when the shadow device is established in the local network, and step 401 is performed when the shadow device is established in the cloud.

It should be noted that, in the environment of internet protocol version 4 (english: internet Protocol version, ipv 4), the setting up position of the shadow device may not be represented by the "SDL" parameter, and the setting up position of the shadow device may be determined by the internet protocol address (Internet Protocol Address, IP) portion in the device port information of the shadow device.

In summary, in the embodiment of the present application, after the terminal device obtains the first discovery resource in the first response message sent by the original device, the shadow device may be automatically identified to be built in the local network or in the cloud according to the location attribute of the shadow device in the first discovery resource, so as to execute a corresponding resource obtaining method, so that a manner of obtaining the second discovery resource of the shadow device by the terminal device is more intelligent.
