FIG. 1 is a schematic diagram of an application scenario of an inter-device communication method provided by an embodiment of the application, and the scenario may be applied to an Internet of Things system. As shown in Figure 1, this scenario includes a client terminal 1, a bridge platform 2, a non-OCF device 3 connected to the bridge platform 2, and a non-OCF device 4 connected to the bridge platform 2, where the bridge platform 2 uses non-OCF protocols and non-OCF devices. The OCF device 3 and the non-OCF device 4 are connected, and the non-OCF device 3 and the non-OCF device 4 are mapped through the bridging function to map the virtual OCF device 31 and the virtual OCF device 41 respectively. The bridge platform 2 implements the following functions: bridge equipment, which represents standard OCF equipment that provides bridging functions; virtual OCF server, namely virtual OCF equipment, which represents non-OCF equipment mapped by the bridged equipment; bridge function, which provides OCF equipment resource models and non-OCF equipment The translation function of the protocol device model. The OCF control instruction sent by the client to the virtual OCF device, where the OCF control instruction conforms to the OCF protocol format, is used to instruct the target non-OCF device to perform the operation corresponding to the OCF control instruction content, and will be converted into the protocol instruction of the non-OCF device through the bridge function Sent to non-OCF devices, where the protocol commands of the non-OCF devices are in the non-OCF protocol format, and the target non-OCF devices can directly parse them, and then perform operations corresponding to the content of the protocol commands according to the analysis results. The status information reported from the non-OCF devices is passed The bridging function will be converted into OCF protocol data and sent to the virtual OCF device. The number of clients and non-OCF devices is not limited. The client can be understood as a terminal device or software installed on the terminal. The terminal can be, but is not limited to, various personal computers, laptops, smart phones, tablets, and portable wearable devices. The bridge platform can be IoT gateways, routers, etc. Non-OCF devices can be zigbee devices, z-wave devices, Bluetooth devices, etc. In order to connect heterogeneous devices to the OCF system, OCF defines a device bridging communication mechanism, and realizes bridging communication with non-OCF devices through OCF bridging devices.

Hereinafter, the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems will be described in detail through the embodiments and the accompanying drawings. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. It should be noted that, in an inter-device communication method provided in an embodiment of the present application, each embodiment is described with different execution subjects.

Fig. 2 is a flowchart of a method for communication between devices according to an embodiment of the application. The execution subject of the method is a first client, and the first client may be the client 1 in Fig. 1. The method involves The process in which the client obtains the resource notification message sent by the bridging platform to determine the connection status of the non-OCF device according to the resource notification message. As shown in Figure 2, the method includes the following steps:

S101. Obtain a resource notification message sent by the bridge platform. The resource notification message carries connection status information. The connection status information is used to indicate the connection status of a non-OCF device, and the non-OCF device is mapped to a corresponding virtual OCF device through the bridge platform.

Among them, the resource notification message may be a message that the bridge platform actively sends to the client when the resource changes, or it may be a response message returned by the bridge platform when the client requests the bridge platform. When the client subscribes to the target resource of the bridge platform, when the target resource changes, the subscription receiver of the bridge platform will actively send the resource notification message corresponding to the target resource to the client. The target resource can be a specified resource or all resources of the bridge platform. The subscription receiver can be a bridge device or a virtual OCF device. Virtual OCF device is a device obtained by translation or mapping of non-OCF device, which is equivalent to the agent of non-OCF device in OCF network. Client and virtual OCF device use OCF protocol to communicate, virtual OCF device and non-OCF device use non-OCF protocol to communicate .

Specifically, the connection status of the non-OCF device can be directly determined through the connection status information. The connection status includes the online status and the offline status. The online status means that the bridge platform and the non-OCF equipment are connected, and the offline status refers to the bridge platform and the non-OCF device. The OCF device is in a disconnected state. Through the connection status information, online non-OCF devices can be determined. The connection status information can have different manifestations according to different information carried in the resource notification message.

Optionally, the connection status information may only include virtual OCF device information corresponding to online non-OCF devices, so that it can directly determine which non-OCF devices are online. Optionally, the connection status information may also include virtual OCF device information and virtual OCF device connection status information corresponding to the non-OCF device, so that the connection status of the corresponding virtual OCF device is determined online or offline according to the virtual OCF device connection status information, thereby Determine the connection status of the non-OCF device corresponding to the virtual OCF device. Optionally, the connection status information may also include the function resources of the virtual OCF device and the resource connection status identification information, so as to determine whether the function resource is online according to the resource connection status identification information corresponding to the function resource, and the function resource corresponding to the function resource is determined according to the online status of the function resource The online status of the non-OCF device. Optionally, the connection status information may also only include the functional resources of the virtual OCF device corresponding to the online non-OCF device, so that the online non-OCF device can be directly determined. Resource notification messages can carry different forms of connection status information, and different forms of connection status information can determine the connection status of non-OCF devices.

Further, the connection status information can be provided for the resources in the bridge device or the resources in the virtual OCF device, where the resources include the virtual OCF device connection status identification information, so that the virtual OCF device's connection status identification information can be determined according to the virtual OCF device connection status identification information. The connection status, so as to determine the connection status of the corresponding non-OCF device according to the connection status of the virtual OCF device. Among them, the virtual OCF device connection state identification information is used to identify the connection state of the virtual OCF device, including online and offline states, which can be represented by 0 or 1.

In this embodiment, after a non-OCF device joins the OCF network through device bridging, the client can determine the connection status of the non-OCF device by obtaining the resource notification message sent by the bridging platform, so that the connection status of the non-OCF device can be clarified. When interacting with OCF devices, you can only select non-OCF devices that are online to interact, avoid interaction failures, and improve the communication efficiency of interconnection and intercommunication of IoT devices.

In some embodiments, the resource notification message is sent by the bridge device in the bridge platform, and the connection status information is determined by the bridge device according to the virtual device list resource, and the virtual device list resource includes the virtual OCF device connection status identification information.

Among them, the virtual device list resource is an OCF resource, used to represent the virtual OCF device information added to the OCF network, which is equivalent to having a list of virtual OCF devices. The actual storage method of the list is not limited, and it can be in table form or text. Form and so on. The virtual device list resource manages the connection status of the virtual OCF device. The virtual device list resource of the bridge device includes the connection status identification information of the virtual OCF device, which is implemented based on the existing OCF resources without the need to create new OCF resources. The virtual OCF device connection state identification information is added to the position corresponding to the matching virtual OCF device information in the virtual device list resource, so that the connection state of the corresponding virtual OCF device is represented by the virtual OCF device connection state identification information.

In this embodiment, the connection status of the non-OCF device is recorded through the device connection status identification information in the virtual device list resource. When a new non-OCF device is connected to the bridge platform, the corresponding virtual OCF device connection is added to the virtual device list resource. Status identification information. At this time, the virtual device list resource is updated. When the bridge platform detects a change in the connection status of the non-OCF device that has been connected to the bridge platform, the virtual device list resource will also update the corresponding virtual OCF device connection status identification information synchronously, and the virtual device list resource is also updated at this time. Therefore, the connection status information determined by the connection status identification information of the virtual OCF device can be carried in the resource notification message, and the client can determine the connection status of the non-OCF device according to the resource notification message.

In some embodiments, when the connection status of the first non-OCF device changes, the virtual OCF device connection status identification information corresponding to the first non-OCF device in the virtual device list resource of the bridge device in the bridge platform is updated, and the first non-OCF device The OCF device is at least one of the non-OCF devices.

Specifically, the bridge platform has a non-OCF device connection status detection function. For example, the bridge platform detects whether the non-OCF device is online through the device heartbeat mechanism, thereby detecting that the connection status of the non-OCF device has changed. When the connection status of the first non-OCF device changes, for example, the first non-OCF device changes from online to a disconnected network connection to the bridge platform, or the first non-OCF device changes from offline to reconnect to the bridge platform, virtual device The connection state identification information of the virtual OCF device corresponding to the first non-OCF device in the list resource is updated.

In some embodiments, the method further includes: sending a subscription request to the bridge device, where the subscription request is used to indicate to subscribe to the virtual device list resource.

Among them, if the client has subscribed to the virtual device list resource of the bridge device, the bridge device can actively send a resource notification message to the client when the resource is updated. Optionally, the target virtual OCF device identification information may be carried in the subscription request, and the resource notification message will be received only when the connection state of the target virtual OCF device corresponding to the target virtual OCF device identification information changes. If the subscription request does not carry the virtual OCF device identifier, the connection status of all virtual OCF devices on the bridge platform will be subscribed.

In this embodiment, by subscribing to the virtual device list resource, when the resource is updated, the bridge device actively sends a resource notification message to the client, and the client can learn the online status of the non-OCF device in real time, which is convenient and efficient.

In some embodiments, the resource notification message is a message sent by the bridge device when virtual OCF device information is added to the virtual device list resource of the bridge device in the bridge platform. The virtual OCF device information includes virtual OCF device connection status identification information.

Specifically, when a new non-OCF device accesses the bridge platform, the bridge device maps the newly accessed non-OCF device as a virtual OCF device, and adds corresponding virtual OCF device information to the virtual device list resource. The corresponding virtual OCF device information can be added to the virtual device list resource after the virtual OCF device is activated, or the corresponding virtual OCF device information can be added to the virtual device list resource when the virtual OCF device is not activated. The virtual OCF device information includes virtual OCF device connection state identification information, which is used to describe the current connection state of the virtual OCF device.

In this embodiment, when new virtual OCF device information is added to the virtual device list resource, the bridge device will send a resource notification message to the client, so that the client can determine the connection status of the newly added non-OCF device in time.

In some embodiments, the resource notification message is a message sent by the bridge device when the virtual OCF device connection status identification information in the virtual device list resource of the bridge device in the bridge platform is updated.

Specifically, when the connection status of the non-OCF device changes, for example, the non-OCF device has been disconnected from the network connection of the bridge platform, the bridge device updates the virtual device list resource, where the virtual OCF device connection status identification information, that is, the virtual OCF device The connection state attribute value changes, and when the virtual OCF device connection state identification information in the virtual device list resource is updated, the bridge device sends a resource notification message to the client.

In this embodiment, when there is currently a non-OCF device whose connection status changes, the bridge device actively sends a resource notification message to the client, so that the client can timely determine the non-OCF device whose connection status changes.

In a specific embodiment, the connection status of the virtual OCF device is managed through the existing vodlist resource, and the vodlist resource of the bridge device includes the connection status identification information of the virtual OCF device, that is, the connection status attribute of the virtual OCF device, as shown in FIG. 3 , The specific process is as follows:

Step 1: The client sends a subscription request to the bridge device to subscribe to the vodlist resource of the bridge device.

Step 2: The bridge device maps the newly accessed first non-OCF device as a virtual OCF device, and exposes the virtual OCF device to the outside.

Step 3: The client activates the virtual OCF device through the device activation process, and the virtual OCF device joins the OCF network.

Step 4: The bridge device adds the activated virtual OCF device information to the vodlist resource, where the virtual OCF device information includes the connection status attribute of the virtual OCF device, and the value of the attribute indicates the connection status of the virtual OCF device.

Add the activated virtual OCF device information to the vodlist resource, where vods represents the added activated virtual OCF device information, as shown below:

The attributes of the vodlist resource include:

rt: indicates the type of vodlist resource, the value is oic.r.vodlist;

vods: indicates the virtual OCF device information, further including the following: n: the name of the virtual OCF device; di: the device identification of the virtual OCF device; econame: the communication protocol used by the non-OCF device, such as zigbee, z-wave, BLE, etc.; status: Virtual OCF device connection status identification information, indicating the connection status of the virtual OCF device, that is, the connection status of the non-OCF device. For example, online means that the non-OCF device is currently online, and offline means that the non-OCF device is currently offline.

Step 5. Since the client has subscribed to the vodlist resource, the bridge device sends a vodlist resource update notification to the client, and the notification message indicates the connection status of the virtual OCF device. For example, the vodlist resource update notification indicates that the virtual OCF device is currently online.

Step 6. The connection status of the first non-OCF device changes. For example, the first non-OCF device has been disconnected from the network connection of the bridge platform. The bridge platform has a non-OCF device connection status detection function and detects that the connection status of the non-OCF device has occurred. change.

Step 7. The bridge device updates the vodlist resource, and the connection state attribute value of the virtual OCF device changes.

When the first non-OCF device becomes disconnected from the network connection of the bridge platform, the vodlist resource is updated as follows:

Among them, the connection state attribute value of the vodlist resource changes to offline, indicating that the first non-OCF device is currently offline.

Step 8. The bridge device sends a vodlist resource update notification to the client, and the notification message indicates the connection status of the virtual OCF device. For example, the vodlist resource update notification indicates that the virtual OCF device is currently offline.

It should be understood that the above-mentioned steps are not necessarily performed sequentially in the above-mentioned order. Unless specifically stated in this article, the execution of these steps is not strictly limited in order, and these steps can be executed in other orders. Moreover, at least some of the steps may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the order of execution of these sub-steps or stages is not necessarily It is performed sequentially, but may be performed alternately or alternately with at least a part of other steps or sub-steps or stages of other steps.

In some embodiments, the resource notification message is sent by the bridge device in the bridge platform, the connection state information is the virtual OCF device connection state resource determination of the bridge device, and the virtual OCF device connection state resource of the bridge device includes the virtual OCF device connection state identification information And virtual OCF device identification information.

Among them, the virtual OCF device connection state resource is specifically used to indicate the connection state of the virtual OCF device, including virtual OCF device connection state identification information and virtual OCF device identification information. The value of the virtual OCF device connection status identification information indicates that the virtual OCF device is connected (online) or disconnected (offline). Since the virtual OCF device is a proxy for the non-OCF device, the virtual OCF device online or offline can represent that the non-OCF device is connected Or disconnect. The virtual OCF device connection state resource is in the bridge device, so that the bridge device centrally manages the connection state information of the virtual OCF device, which facilitates unified management and improves management efficiency.

In this embodiment, the connection status of the non-OCF device is recorded through the device connection status identification information in the virtual OCF device connection status resource of the bridge device. When a new non-OCF device is connected to the bridge platform, the virtual OCF device in the bridge device is connected The virtual OCF device information is added to the state resource, and the virtual OCF device information includes the virtual OCF device connection state identification information. At this time, the virtual OCF device connection state resource is updated. When the bridge platform detects a change in the connection status of a non-OCF device that has been connected to the bridge platform, the virtual OCF device connection status resource will also update the corresponding virtual OCF device connection status identification information. At this time, the virtual OCF device connection status resource is also updated. Update. Therefore, the connection status information determined by the connection status identification information of the virtual OCF device can be carried in the resource notification message, and the client can determine the connection status of the non-OCF device according to the resource notification message.

In some embodiments, when the connection status of the first non-OCF device changes, the connection status identification information of the virtual OCF device corresponding to the first non-OCF device in the virtual OCF device connection status resource of the bridge device in the bridge platform is updated. A non-OCF device is at least one of the non-OCF devices.

Specifically, the bridge platform has a non-OCF device connection status detection function. For example, the bridge platform detects whether the non-OCF device is online through the device heartbeat mechanism, thereby detecting that the connection status of the non-OCF device has changed. When the connection status of the first non-OCF device changes, for example, the first non-OCF device changes from online to a disconnected network connection to the bridge platform, or the first non-OCF device changes from offline to reconnect to the bridge platform, and the bridge device The connection state identification information of the virtual OCF device corresponding to the first non-OCF device in the virtual OCF device connection state resource is updated.

In this embodiment, the virtual OCF device connection state resource is one of the resources of the bridge device, and the virtual OCF device connection state resource is updated by the bridge device.

In some embodiments, the method further includes: sending a subscription request to the bridge device, where the subscription request is used to instruct the virtual OCF device connection state resource of the subscribed bridge device.

Among them, if the client subscribes to the virtual OCF device connection state resource of the bridge device, the bridge device can actively send a resource notification message to the client when the resource is updated. The virtual OCF device connection state resource is one of the resources of the bridge device, and the virtual OCF device connection state resource of the bridge device provides connection state information of the virtual OCF device. Optionally, the target virtual OCF device identification information may be carried in the subscription request, and the resource notification message will be received only when the connection state of the target virtual OCF device corresponding to the target virtual OCF device identification information changes. If the subscription request does not carry the virtual OCF device identifier, it will subscribe to the connection status of all virtual OCF devices on the bridge platform. If the connection status of any virtual OCF device changes, the client will receive a resource notification message.

In this embodiment, by subscribing the virtual OCF device connection status resource to the bridge device, when the resource is updated, the bridge device actively sends a resource notification message to the client, and the client can learn the online status of the non-OCF device in real time, which is convenient and efficient.

Step 8. The bridge device updates the virtual OCF device connection state resource, where the connection state attribute value of the virtual OCF device changes.

In one embodiment, the virtual OCF device connection state resource update is as follows:

Wherein, the connection state attribute value of the virtual OCF device connection state resource becomes offline, indicating that the first non-OCF device is currently offline.

Step 9: The bridge device sends the virtual OCF device connection status resource update notification to the client, and the notification message indicates the connection status of the virtual OCF device. For example, the virtual OCF device connection status resource update notification indicates that the virtual OCF device is currently offline.

In some embodiments, the resource notification message is sent by the virtual OCF device in the bridge platform, the connection status information is the virtual OCF device connection status resource determination of the virtual OCF device, and the virtual OCF device connection status resource of the virtual OCF device includes the virtual OCF device connection Status identification information and virtual OCF device identification information.

Among them, the virtual OCF device connection state resource is specifically used to indicate the connection state of the virtual OCF device, including virtual OCF device connection state identification information and virtual OCF device identification information. The value of the virtual OCF device connection status identification information indicates that the virtual OCF device is connected (online) or disconnected (offline). Since the virtual OCF device is a proxy for the non-OCF device, the virtual OCF device online or offline can represent that the non-OCF device is connected Or disconnect. Virtual OCF device connection state resource In the virtual OCF device, the virtual OCF device connection state resource is one of the resources of the virtual OCF device itself. The virtual OCF device updates the virtual OCF device connection state resource, so that each virtual OCF device manages its own connection state Information makes the management time division clearer, simpler and more convenient. Even if a large number of non-OCF devices join the OCF network through bridges, they can be managed in an orderly manner.

In this embodiment, the connection status of the non-OCF device is recorded through the device connection status identification information in the virtual OCF device connection status resource of the virtual OCF device. When a new non-OCF device is connected to the bridge platform, the corresponding Virtual OCF device, the added virtual OCF device includes the virtual OCF device connection state resource, the virtual OCF device connection state resource includes virtual OCF device information, and the virtual OCF device information includes virtual OCF device connection status identification information. At this time, the virtual OCF device connection state Resource update. When the bridge platform detects a change in the connection status of a non-OCF device that has been connected to the bridge platform, the virtual OCF device connection status resource will also update the corresponding virtual OCF device connection status identification information. At this time, the virtual OCF device connection status resource is also updated. Update. Therefore, the connection status information determined by the connection status identification information of the virtual OCF device can be carried in the resource notification message, and the client can determine the connection status of the non-OCF device according to the resource notification message.

In some embodiments, when the connection state of the first non-OCF device changes, the virtual OCF device connection state identification information in the virtual OCF device connection state resource of the virtual OCF device corresponding to the first non-OCF device is updated, and the first non-OCF device The device is at least one of the non-OCF devices.

Specifically, the bridge platform has a non-OCF device connection status detection function. For example, the bridge platform detects whether the non-OCF device is online through the device heartbeat mechanism, thereby detecting that the connection status of the non-OCF device has changed. When the connection status of the first non-OCF device changes, for example, the first non-OCF device changes from online to a disconnected network connection to the bridge platform, or the first non-OCF device changes from offline to reconnect to the bridge platform, the first The virtual OCF device connection state identification information in the virtual OCF device connection state resource of the virtual OCF device corresponding to the non-OCF device is updated.

In this embodiment, the virtual OCF device connection state resource is one of the resources of the virtual OCF device, and the virtual OCF device connection state resource is updated by the virtual OCF device.

In some embodiments, the method further includes: sending a subscription request to a virtual OCF device or a bridge device, where the subscription request is used to indicate to subscribe to the virtual OCF device connection state resource of the virtual OCF device.

Wherein, if the client subscribes to the virtual OCF device connection state resource of the virtual OCF device, when the resource is updated, the virtual OCF device can actively send a resource notification message to the client. The virtual OCF device connection state resource is one of the resources of the virtual OCF device, and the virtual OCF device connection state resource of the virtual OCF device provides connection state information of the virtual OCF device. Optionally, a subscription request can be sent to one or more virtual OCF devices to subscribe to the virtual OCF device state resources of the virtual OCF device, and the subscription request can be sent only to the target virtual OCF device, and only the target virtual OCF device identification information corresponding to the target virtual The resource notification message will be received only when the connection status of the OCF device changes. You can also send a subscription request to all virtual OCF devices on the bridge platform to subscribe to the connection status of all virtual OCF devices on the bridge platform. If the connection status of any virtual OCF device changes, the client will receive a resource notification message.

Optionally, a subscription request can be sent to the bridge device. The subscription request indicates to subscribe to the virtual OCF device connection status resource of the virtual OCF device. As long as a new virtual OCF device is generated in the bridge device, the new virtual OCF device will notify the client of it For connection status information, the client will receive a resource notification message.

In this embodiment, by subscribing to the virtual OCF device or bridge device for the virtual OCF device connection status resource, when the resource is updated, the virtual OCF device actively sends a resource notification message to the client, and the client can learn the online status of the non-OCF device in real time. Status, convenient and efficient.

In some embodiments, the resource notification message is a message sent by the added virtual OCF device when a virtual OCF device is added to the bridge platform. The added virtual OCF device includes a virtual OCF device connection state resource, and the virtual OCF device connection state resource includes a virtual OCF. Device information, virtual OCF device information includes virtual OCF device connection status identification information.

Specifically, when a new non-OCF device accesses the bridge platform, the bridge device maps the newly accessed non-OCF device as a virtual OCF device, and adds the corresponding virtual OCF device connection state resource in the virtual OCF device. OCF device information. The corresponding virtual OCF device information can be added to the virtual OCF device connection state resource after the virtual OCF device is activated, or the corresponding virtual OCF device information can be added to the virtual OCF device connection state resource when the virtual OCF device is not activated. The virtual OCF device information includes virtual OCF device connection state identification information, which is used to describe the current connection state of the virtual OCF device.

In this embodiment, when a virtual OCF device is added to the bridge platform, the newly added virtual OCF device will send a resource notification message to the client, so that the client can determine the connection status of the newly added non-OCF device in time.

In some embodiments, the resource notification message is a message sent by the virtual OCF device when the virtual OCF device connection state identification information of the virtual OCF device connection state resource in the virtual OCF device is updated.

Specifically, when the connection status of the non-OCF device changes, for example, the non-OCF device has been disconnected from the network connection of the bridge platform, the virtual OCF device updates the virtual OCF device connection state resource, where the virtual OCF device connection state identification information, that is, virtual The connection state attribute value of the OCF device changes, and when the virtual OCF device connection state identification information in the virtual OCF device connection state resource is updated, the virtual OCF device sends a resource notification message to the client.

In this embodiment, when there is currently a non-OCF device whose connection status has changed, the virtual OCF device actively sends a resource notification message to the client, so that the client can promptly determine the non-OCF device whose connection status has changed.

In a specific embodiment, the connection state of the virtual OCF device is managed by the virtual OCF device connection state resource of the newly added virtual OCF device. The virtual OCF device connection state resource includes the virtual OCF device connection state identification information, that is, the connection of the virtual OCF device. State attributes, as shown in Figure 5, the specific process is as follows:

Step 1. The bridge device maps the newly connected first non-OCF device as a virtual OCF device, and exposes the virtual OCF device to the outside. The virtual OCF device includes the virtual OCF device connection state resource, and the virtual OCF device connection state resource includes the virtual OCF device. Information, the virtual OCF device information includes the connection state attribute of the virtual OCF device, and the value of the attribute indicates the connection state of the virtual OCF device.

In one embodiment, the virtual OCF device connection state resource is as follows:

The attributes of the virtual OCF device connection state resource include:

·If: The interface of the virtual OCF device connection status resource;

·Di: the device identification of the virtual OCF device;

Step 2: The client activates the virtual OCF device through the device activation process, and the virtual OCF device joins the OCF network.

Step 3: The bridge device adds the activated virtual OCF device information to the vodlist resource.

Step 4: The client sends a subscription request to the virtual OCF device to subscribe to the virtual OCF device connection state resource of the virtual OCF device.

Step 5. Since the client has subscribed to the virtual OCF device connection state resource, the virtual OCF device sends a virtual OCF device connection state resource update notification to the client, and the notification message indicates the connection state of the virtual OCF device. For example, the resource update notification indicates that the virtual OCF device is currently online.

Step 7. The virtual OCF device updates the connection state resource of the virtual OCF device, where the connection state attribute value of the virtual OCF device changes.

Step 8. The virtual OCF device sends a virtual OCF device connection status resource update notification to the client, and the notification message indicates the connection status of the virtual OCF device. For example, the virtual OCF device connection status resource update notification indicates that the virtual OCF device is currently offline.

Optionally, the virtual OCF device connection state resource in the virtual OCF device or the bridge device further includes at least one of the following information: type information of the virtual OCF device connection state resource; and interface information of the virtual OCF device connection state resource. Among them, the type information of the virtual OCF device connection status resource is generally a preset value, for example, the value is oic.r.vodConnectionStatus, which represents the resource type. The interface of the virtual OCF device connection status resource is a parameter used when operating the resource. For example, if the client wants to read the virtual OCF device connection status resource, the read request will bring the rw interface or the baselien interface, and these two interfaces will get the return. The content is different.

In some embodiments, the method further includes: sending a device discovery request, where the device discovery request is used to instruct to discover a virtual OCF device or to discover a virtual OCF device in an online connection state.

Among them, a restriction condition can be added to the device discovery request to discover only virtual OCF devices, because there may also be real OCF devices, such as bridge devices, in the network, and restriction conditions can be added to realize that only virtual OCF devices can be discovered. When the device discovery request is used to indicate the discovery of a virtual OCF device, the returned response message may carry information including the virtual OCF device corresponding to the non-OCF device and the connection status information of the virtual OCF device.

When the device discovery request is used to indicate the discovery of a virtual OCF device in an online connection state, the response message returned by the control includes only the virtual OCF device information in the online state, for example, only the virtual OCF device information corresponding to the online non-OCF device is included.

Optionally, the device discovery request is at least one of the following requests: a multicast device discovery request sent to the OCF network; a unicast device discovery request sent to a bridge device; a unicast device discovery request sent to a virtual OCF device.

Among them, the multicast device discovery request is that the client joins the multicast group. All devices in the multicast group will receive the multicast request, and the bridge device, virtual OCF device, and other OCF devices will all receive the device discovery request. Therefore, the device that receives the multicast device discovery request returns a corresponding response message according to the online status of the virtual OCF device.

The unicast device discovery request is a point-to-point communication. The client sends a device discovery request to a certain target device. For example, it sends a device discovery request to a bridge device. Only the bridge device will receive it. Send a device discovery request to a virtual OCF device. Only virtual OCF. The device will receive it. Therefore, the device that receives the unicast device discovery request returns a corresponding response message according to the online status of the virtual OCF device.

In some embodiments, the resource notification message is a response message generated according to a device discovery request. The response message is used to indicate the virtual OCF device information corresponding to the online non-OCF device, and the device discovery request is used to indicate the discovery of a virtual OCF device in an online connection state. OCF equipment.

In some embodiments, the resource notification message is a response message generated according to a device discovery request, and the response message includes virtual OCF device information and virtual OCF device connection status information corresponding to a non-OCF device, and the device discovery request is used to indicate discovery Virtual OCF device.

Among them, the response message has two possibilities: 1. It includes the device identifier of the virtual OCF device and the connection status information of the corresponding virtual OCF device; 2. It includes the device identifier of the virtual OCF device, and only the device identifier of the online virtual OCF device.

If the response message includes the device identification of the virtual OCF device and the connection status information of the corresponding virtual OCF device, the connection status of the virtual OCF device can be determined according to the connection status information of the virtual OCF device, thereby determining the connection status of the non-OCF device. The response message generated by the device discovery request is sent to the client as a resource notification message, so that the client can determine the connection status of the non-OCF device.

If the response message only includes the device identification of the online virtual OCF device, you can directly determine the online non-OCF device, and send the response message generated by the device discovery request as a resource notification message to the client, so that the client can determine the online non-OCF device .

In one embodiment, the client sends a device discovery request, and the received response message includes only the virtual OCF device information corresponding to the online non-OCF device, or the response message includes the virtual OCF device information corresponding to the non-OCF device and the virtual OCF device connection Status information, as shown in Figure 6, the specific process is as follows:

Step 1: The bridge device maps the newly accessed first non-OCF device as a virtual OCF device, and exposes the virtual OCF device to the outside.

Step 4. The client sends a device discovery request;

Step 5. The response message received by the client only includes virtual OCF device information corresponding to the online non-OCF device, or the response message includes virtual OCF device information and virtual OCF device connection status information corresponding to the non-OCF device.

In some embodiments, the connection state information is determined by the functional resource of the virtual OCF device corresponding to the non-OCF device, and the functional resource includes resource connection state identification information.

Specifically, the functional resources of the virtual OCF device correspond to the functional modules of the non-OCF device. For example, a non-OCF device TV includes switch, channel adjustment, and volume adjustment functions. The TV is mapped to a virtual OCF device, and the virtual OCF device supports The function resource of the TV should be the switch resource, the OCF resource type is oic.r.binarySwitch, channel adjustment resource, the OCF resource type is oic.r.channelChange, volume adjustment resource, and the OCF resource type is oic.r.audio. Each functional resource has corresponding resource connection status identification information. The resource connection status identification information is used to describe whether the current functional resource is online, and it can be online or offline. If the functional resources corresponding to a non-OCF device are all online, it can be judged that the non-OCF device is online, and if the functional resources corresponding to a non-OCF device are all offline, it can be judged that the non-OCF device is offline. Therefore, the connection status information is determined according to the connection status of the functional resources of the virtual OCF device, and the connection status information is carried in the resource notification message and returned to the client. The returned resource notification message may directly include each function resource and the corresponding resource connection status identification information, or it may only include the function resources corresponding to the online non-OCF device determined according to the resource connection status identification information.

In this embodiment, the connection status information is determined by the functional resources of the virtual OCF device. When the non-OCF device and the virtual OCF device are in a many-to-one mapping relationship, that is, when multiple non-OCF devices are mapped to a virtual OCF device, if some non-OCF devices are The connection status of the OCF device changes. For example, some non-OCF devices are disconnected and the bridge platform is connected. The virtual OCF device mapped by the bridge device may not expose the resources of the offline non-OCF device function, or provide the function resources of the corresponding non-OCF device Connection status information attributes. This method can also be used when a non-OCF device is mapped to a virtual OCF device.

In some embodiments, the resource notification message filters offline functional resources based on the resource connection status identification information corresponding to each functional resource, including functional resource information corresponding to the online functional resources.

Specifically, according to the resource connection status identification information corresponding to each functional resource, the offline functional resources are filtered, and only the functional resource information corresponding to the online functional resources is left as a resource notification message, so that only the online functional resources Exposed to the client, the offline function resources are automatically hidden.

In some embodiments, the connection status information is determined by the functional resources of the virtual OCF device corresponding to the online non-OCF device.

Specifically, the online non-OCF device is determined first, and then the connection status information is determined through the functional resources of the virtual OCF device corresponding to the online non-OCF device, and only the functional resources corresponding to the online non-OCF device are exposed to the client, which is automatically hidden Functional resources in offline state.
