All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The terms "first," "second," and the like in the description and in the claims, and in the drawings, of the embodiments of the application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are, for example, capable of operation in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Before introducing the solutions provided in the embodiments of the present application, a network system applied in the embodiments of the present application will be described below. Fig. 1 is a schematic diagram of an internet of things system applied in the embodiment of the present application. As shown in fig. 1, the internet of things system includes a service device 11, a network device 12, a configuration device 13, and a client device 14. It is understood that, in practical applications, the service device 11, the configuration device 13 and the client device 14 may be one or more, and this fig. 1 is only taken as an example. The service device 11 is connected to the network device 12 and the configuration device 13, respectively, and the network device 12 is also connected to the configuration device 13 and the client device 14, respectively. The connection between the above devices may be a wired connection or a wireless connection, which is not specifically limited in this embodiment of the present application.

The service device 11 may be an entity providing resources, and may be a data acquisition device such as a sensor or a data acquisition card, an electrical component device such as a switch, a socket, or a lamp, or an electronic device such as an air conditioner, a washing machine, a refrigerator, a sound box, or a television. Of course, the above is only some possible examples of the service device 11, and the service device 11 may also be other intelligent hardware devices that can provide resources and implement corresponding functional services, which is not described herein again in this embodiment of the present application. The service device 11 may be referred to as an Open Connectivity Foundation (OCF) service end entity, a resource provider, or a resource device.

The network device 12 may be a device for performing shadow device deployment, that is, a shadow device 121 corresponding to the service device 11 may be deployed in the network device 12, and the shadow device 121 deployed in the network device 12 is a virtual device (or referred to as a virtual network device). The resources in the service device 11 and the resources corresponding to the shadow device 121 in the network device 12 need to be synchronized, so that the resources corresponding to the service device 11 and the shadow device 121 are the same. For example, the network device 12 may be a cloud platform, gateway, or the like. Optionally, the network device 12 is a device that does not need to be dormant, that is, the network device 12 is a device that can continuously operate.

The configuration device 13 is used to configure the shadow device 121 in the network device 12 and the service device 11. For example, the configuration device 13 may send a configuration instruction to the service device 11 to make the service device 11 request to generate the corresponding shadow device 121 in the network device 12, and the configuration device 13 may also send information such as a service identifier for generating the shadow device in the network device 12, an identifier for generating a resource of the shadow device, and the like to the service device 11.

The entity that the client device 14 can access the resource may be a terminal device installed with an OCF client application, and the terminal device may be any one of a desktop computer, a notebook computer, a Personal Digital Assistant (PDA), a smart phone, a tablet computer, and the like. Client devices 14 may also be referred to as OCF client devices, user devices, or customer premise equipment, etc.

Based on the current technology, an information synchronization table and a shadow synchronization resource need to be maintained in a service device and a network device. When any resource of any one of the service device and the network device changes, the content in the information synchronization table needs to be updated, so that the maintenance complexity of the information synchronization table is high, and the resource synchronization complexity is high. When any one of the information synchronization table and the shadow synchronization resource is abnormal, the resource synchronization between the service device and the network device is abnormal, and the reliability of the resource synchronization is poor.

In this application, the location information of the resource in the network device is included in the service device, so that when the resource in the service device is updated, the service device can synchronize the updated resource with the network device according to the location information of the resource in the network device. The location information of the resource in the service device is included in the network device, so that when the resource in the network device is updated, the network device can synchronize the updated resource with the service device according to the location information of the resource in the service device. The information synchronization table and the shadow synchronization resources do not need to be maintained in the network equipment and the network equipment, so that the resource synchronization process is simplified, and the reliability of the resource synchronization is improved.

The technical solution described in the present application will be described in detail by specific examples. It should be noted that the following embodiments may be independent or combined with each other, and the description of the same or similar contents is not repeated in different embodiments.

Fig. 2 is a schematic flowchart of a resource synchronization method according to an embodiment of the present application. In the embodiment shown in fig. 2, a process of synchronizing the service resource to the network device by the service device is taken as an example for explanation. Referring to fig. 2, the method may include:

s201, the service equipment acquires the position information of the service resource in the network equipment.

The shadow device referred to in the present application refers to a device deployed in a network device, and the shadow device may be a virtual device, and may also be referred to as a virtual network device.

Wherein the service resource corresponds to the shadow device. That is, the service resource is a service resource corresponding to the shadow device.

One or more shadow devices may be deployed in the network device, where a shadow device shown in this application is a shadow device corresponding to a service device shown in this application.

Optionally, the function of the shadow device corresponding to one service device may be a part of the functions of the service device.

For example, assuming that the service device is a temperature sensor having a function of detecting a temperature, a function of providing a temperature value inquiry, a function of alarming when the temperature exceeds a preset temperature range, a function of modifying the preset temperature range, etc., the shadow device may have a function of providing a temperature value inquiry and a function of modifying the preset temperature range.

It should be noted that the location information of the service resource in the network device may refer to the location information of the service resource in the corresponding shadow device.

Optionally, the service device may include one or more service resources, where the service resource referred to in this application may be any service resource of the service device, and the service resource may also be referred to as an OFC resource.

Optionally, the service resource may be a functional resource of the service device, and the functional resource of the service device is related to a function of the service device, for example, when the temperature sensor of the service device is used, the functional resource of the service device is a temperature resource. When the service device is a humidity sensor, then the functional resource of the service device may be a humidity resource.

Optionally, one service device may correspond to at least one service resource.

The number of service resources corresponding to a service device is related to the number of functions the service device has. Optionally, the number of service resources corresponding to the service device is the same as the function data of the service device. For example, when the service device is a temperature sensor, it is assumed that the temperature sensor has two functions as follows: function 1, provide the current temperature value. And 2, alarming when the temperature exceeds a preset temperature range. The temperature sensor has two service resources: one is the current temperature value resource corresponding to function 1, and the other is the temperature range resource corresponding to function 2.

Optionally, the Resource information of the service Resource in the service device may include a Uniform Resource Identifier (URI) of the service Resource, a type of the service Resource, a general interface of the service Resource, a functional attribute of the service Resource, and location information of the service Resource in the network device.

The URI of a service resource is used to indicate the address of the service resource, which can be accessed through a resource URI of a service resource. For example, the URI of a service resource can be represented by "href", the value of which is the URI of the service resource.

The type of the service resource may be represented by "rt", and the value of "rt" is the type of the service resource. In the present application, a type of service resource may include two types, one is a functional type of service resource, for example, a temperature type, a humidity type, a speed type, and the like. The other is a synchronization type of the service resource, for example, a push type and a subscription type, where the push type means that when the service resource of the service device is updated, the service device actively synchronizes the updated resource with the network device. The subscription type means that the service device can subscribe to resource changes of the shadow device, so that after the service resource corresponding to the shadow device is updated, the network device sends the updated resource to the service device. It should be noted that, because the shadow device is deployed in the network device, the service resource corresponding to the shadow device may also be referred to as a resource in the network device.

The generic interface of a service resource specifies a method for operating (e.g., viewing, synchronizing, modifying, etc.) the service resource, that is, when operating a service resource, the service resource needs to be operated by the method specified by the generic interface corresponding to the service resource. For example, the generic interface of the service resource may be represented by "if", and the value of "if" is the generic interface of the service resource.

The attribute information of the service resource is used to indicate a value of the service resource, for example, if the service resource is a resource with a current temperature value, the attribute information of the service resource is the current temperature value, and if the service resource is a resource with a temperature range, the attribute information of the service resource is the temperature range.

The location information of the service resource in the network device may be a URI of the service resource in the network device. When the type of the service resource includes a push type, the push target "may represent location information of the service resource in the network device, and a value of the" push target "is the location information of the service resource in the network device. When the type of the service resource includes the subscription type, the location information of the service resource in the network device may be represented by an observation target "observed target", and a value of the "observed target" is the location information of the service resource in the network device.

Optionally, the resource information of the service device may further include a synchronization interface used for the synchronization operation. For example, the synchronization interface used by the synchronization operation may be represented by "qif", and the value of "qif" is the synchronization interface used by the synchronization operation. Wherein the generic interface comprises a synchronous interface. The synchronous interface is an interface used for resource synchronization between the devices.

Optionally, the resource information of the service device may further include a resource type of the synchronization operation, that is, the resource type of the synchronization between the service device and the network device in a push manner or a subscription manner. For example, the resource type of the synchronization operation can be represented by "qrt", and the value of "qrt" is the resource type of the synchronization operation.

For example, the resource information of the current temperature value resource may be as follows:

{"rt":[“oic.r.temperature”,"oic.r.pushproxy"],

"if":["oic.if.s","oic.if.baseline"],

"temperature":20,

"pushtarget":"coaps://[fe80::b1d6]:2222/temperature",

"qif":["oic.if.s"],

"qrt":["oic.r.temperature"]

}

as can be known from the resource information of the current temperature value resource, the type of the current temperature value resource includes "oic.r.temperature" and "oic.r.pushproxy", where "oic.r.temperature" indicates that the type of the current temperature value resource is the temperature value type, and "oic.r.pushproxy" indicates that the type of the current temperature value resource is the push type. Common interfaces for current temperature value resources include "oic. The attribute information of the current temperature value resource (i.e., the current temperature value) is 20. The location information of the current temperature value resource in the network device is "maps:// [ fe80:: b1d 6:: 2222/temperature", that is, the URI of the current temperature value resource in the network device is "maps:// [ fe80:: b1d 6: 2222/temperature", wherein [ fe80:: b1d6]:2222 is endpoint information (or is called Internet Protocol (IP) Address), and one service resource is associated with at least one endpoint information. The synchronization interface used for performing the synchronization operation in the push mode is "oic. The resource type synchronized by the push method is "oic.

For example, the resource information of the temperature range resource may be as follows:

{"rt":[“oic.r.temperatureRange”,"oic.r.observeproxy"],

"if":["oic.if.a","oic.if.baseline"],

"temperatureRange":[0,30],

“observetarget":"coaps://[fe80::b1d6]:2222/temperatureRange",

"qif":["oic.if.a"],

"qrt":["oic.r.temperatureRange"]

}

as can be seen from the resource information of the temperature range resource, the type of the temperature range resource includes "oic.r.temperature range" and "oic.r.ob serverproxy", where "oic.r.temperature range" indicates that the type of the temperature range resource is the temperature range type, and "oic.r.pushproxy" indicates that the type of the temperature range resource is the subscription type. Common interfaces for temperature range resources include "oic. if.a" and "oic. if.baseline". The attribute information (temperature range) of the temperature range resource is [0, 30 ]. The location information of the temperature range resource in the network device is "maps:// [ fe80:: b1d 6:: 2222/temporal range," i.e., the URI of the temperature range resource in the network device is "maps:// [ fe80:: b1d 6: 2222/temporal range. The synchronization interface used for performing the synchronization operation in the subscription mode is "oic. The resource type for synchronization by push is "oic.

S202, the service equipment synchronizes service resources with the network equipment according to the position information.

Optionally, the service device may obtain the type of the service resource first, and synchronize the service resource with the network device according to the location information when it is determined that the type of the service resource is a push type or a subscription type.

Optionally, when the types of the service resources are different, the process of synchronizing the service resources by the service device and the network device according to the location information is also different, and the following two possible situations may be included:

one possible scenario is: the type of service resource is a push type.

When the type of the service resource is a push type, the service device may determine whether the service resource in the service device is updated, and after the service device determines that the service resource is updated, the service device may send the service resource to the network device according to the type and the location information of the service resource. Optionally, after the network device receives the service resource, the service resource may be synchronized to a shadow device corresponding to the service device.

Optionally, after one service resource in the service device is updated, the service device may determine whether the type of the service resource includes a push type, and if so, the service device may send the service resource to the network device according to the push type and location information of the service resource in the network device. Optionally, after the network device receives the service resource, the service resource may be synchronized to a shadow device corresponding to the service device.

Optionally, the service device may send an update request to the network device, where the update request includes location information of the service resource in the network device and the updated service resource, so that the network device updates the service resource in the location information according to the update request.

Optionally, when the resource information includes the synchronization interface, the service device may send the service resource to the network device according to the synchronization interface in the resource information.

It should be noted that, the service device sending the service resource according to the synchronization interface in the resource information by the network device means that the service device sends the service resource to the network device according to the method indicated by the synchronization interface in the resource information.

Another possible scenario is: the type of service resource is a subscription type.

Optionally, when the type of the service resource of the service device is a subscription type, the service device may subscribe to a change of the shadow device corresponding to the service resource, and after the resource corresponding to the shadow device is updated, the updated resource is sent to the service device.

Optionally, when the service device determines that the type of one service resource includes the subscription type, the service device sends a subscription request of the service resource to the network device according to the type and the location information of the service resource. Optionally, the subscription request may include location information of the service resource in the network device. Correspondingly, after the service resource corresponding to the shadow device in the network device is updated, the network device sends the service resource to the service device according to the subscription request.

Optionally, when the resource information includes the synchronization interface, the service device sends a subscription request to the network device through the synchronization interface in the resource information.

It should be noted that, the service device sending the subscription request to the network device through the synchronization interface in the resource information means that the service device sends the subscription request to the network device through a method indicated by the synchronization interface in the resource information.

According to the resource synchronization method provided by the embodiment of the application, the service equipment can acquire the resource information of the service resource, the resource information comprises the position information of the service resource in the network equipment, and the service equipment synchronizes the service resource with the network equipment according to the position information. In the process, the information synchronization table and the shadow synchronization resource do not need to be maintained in the service equipment and the network equipment, so that the resource synchronization process is simplified, and the reliability of the resource synchronization is improved.

On the basis of the embodiment shown in fig. 2, optionally, before the service device synchronizes the resource to the network device, the resource information of the service resource needs to be generated in the service device. Next, a process of the service device generating resource information of the service resource will be described in detail.

Fig. 3 is a flowchart illustrating a method for generating resource information of a service resource in service equipment according to an embodiment of the present application. Referring to fig. 3, the method may include:

s301, the configuration device sends a configuration instruction to the service device.

The configuration instruction is used to instruct to add a push type or a subscription type to the service resource in the service device, that is, to add a push type or a subscription type to the type of the service resource.

Optionally, the configuration instruction may be further configured to instruct to add location information to the service resource in the service device, where the location information refers to location information of the service resource in the network device.

Optionally, the configuration instruction may be further configured to instruct to add a synchronization interface and a synchronization resource type to the service resource;

optionally, the configuration instruction may further include at least one of an identifier of the service resource, a synchronization interface, and a type of the service resource.

When the configuration instruction includes the identity of the service resource, the configuration instruction may instruct to add a push type or a subscription type to the service resource indicated by the identity of the service resource.

When the configuration instruction includes a synchronous interface, the configuration instruction may instruct to add a push type or a subscription type to a service resource corresponding to the synchronous interface, where the service resource corresponding to the synchronous interface may be a service resource using the synchronous interface.

When the configuration instruction includes a type of service resource, then the configuration instruction may instruct to add a push type or a subscription type to the service resource of the type of service resource.

S302, the configuration device sends a shadow device generation instruction to the service device.

The shadow device generation instruction is used for indicating the service device to request to generate a shadow device corresponding to the service device in the network device.

Optionally, the shadow device generation instruction may further include at least one of an identification of the service resource, a synchronization interface, and a type of the service resource.

Optionally, the identifier of the service resource included in the shadow device generation instruction is the same as the identifier of the service resource included in the configuration instruction. The synchronization interface included in the shadow device generation instruction is the same as the synchronization interface included in the configuration instruction. The type of the service resource included in the shadow device generation instruction is the same as the type of the service resource included in the configuration instruction.

It should be noted that in S301 and S302, the configuration device may also send a configuration instruction and a shadow device generation instruction to the service device in the form of one instruction.

S303, the service equipment adds a push type or a subscription type in the resource information of the service resource in the service equipment according to the configuration instruction.

Optionally, a push type or a subscription type may be added to the initial resource information of the service resource. The initial resource of the service resource comprises the URI of the service resource, the type of the service resource, the general interface of the service resource and the functional attribute of the service resource. The type of the service resource in the initial resource includes a functionality type of the service resource, for example, a temperature type, a humidity type, a speed type, and the like. The type of service resource in the initial resource does not include a push type or a subscription type.

For example, the initial resource information of the current temperature value resource may be as follows:

{"rt":[“oic.r.temperature”],

"if":["oic.if.s","oic.if.baseline"],

"temperature":20

}

optionally, if the configuration information includes an identifier of the service resource, the service device adds a push type or a subscription type to initial resource information of the service resource indicated by the service resource identifier.

Optionally, if the configuration information includes a synchronization interface, the service device adds a push type or a subscription type to initial resource information of a service resource corresponding to the synchronization interface.

Optionally, if the configuration information includes the type of the service resource, the service device adds a push type or a subscription type to the initial resource information of the service resource of the type of the service resource.

It should be noted that, if the configuration information does not include at least one of the identifier of the service resource, the synchronization interface, and the type of the service resource, the service device may add a push type or a subscription type in the initial resource information of all the service resources, or add a push type or a subscription type in the initial resource information of the preset service resource, or add a push type or a subscription type in the initial resource information of the service resource corresponding to the preset interface type, or add a push type or a subscription type in the initial resource information of the preset type of service resource.

S304, the service equipment adds at least one attribute in the resource information of the service resource.

It should be noted that S304 is an optional step. S304 is performed, for example, when the configuration instruction is further used to instruct adding location information for the service resource, and/or the configuration instruction is further used to instruct adding a synchronization interface and a synchronization resource type for the service resource.

Optionally, when the configuration instruction is further used to instruct to add location information to the service resource, the at least one attribute includes a location attribute. When the configuration instruction is used to instruct the addition of a synchronization interface and a synchronization resource type for the service resource, then the at least one attribute comprises a synchronization interface attribute or a synchronization resource type attribute.

Optionally, if the configuration information includes an identifier of the service resource, the service device adds at least one attribute to initial resource information of the service resource indicated by the service resource identifier.

If the resource information of the service resource 2 needs to be synchronized in the network device, the shadow device generates a request carrying the resource information of the service resource 2. If the resource information of the service resource 1 and the service resource 2 needs to be synchronized in the network device, the shadow device generates a request carrying the resource information of the service resource 1 and the service resource 2.

}

Optionally, the shadow device generation request may further include a resource synchronization mode of the service device, where the resource synchronization mode of the service device is a push synchronization mode or a subscription synchronization mode.

The resource information corresponding to the shadow device may include location information of the service resource in the network device, a synchronization interface, and a synchronization resource type, where the synchronization resource type is a push type or a subscription type.

Optionally, the resource information corresponding to the shadow device sent by the network device to the service device may further include other information, which is not specifically limited in this embodiment of the present application.

Optionally, the service device sets the value of the location attribute as location information; the service equipment sets the value of the attribute of the synchronous interface as the synchronous interface; the serving device sets the value of the synchronization resource type attribute to the synchronization resource type.

In the embodiment shown in fig. 3, the configuration device may send a configuration instruction to the service device, where the configuration instruction indicates that the service device is a new push type or a subscription type for the service resource, and after the service device requests the network device to create a shadow device, the network device creates a shadow device corresponding to the service device, and returns resource information corresponding to the shadow device to the service device. The service device may generate resource information of the service resource according to the configuration instruction and the resource information corresponding to the shadow device, so that the resource information of the service resource includes a synchronization type (a push type or a subscription type) of the service resource and location information of the service resource in the network device. Accordingly, when the service resource in the service device is updated, the service device may send the updated service resource to the network device according to the synchronization type (push type or subscription type) of the service resource and the location information of the service resource in the network device.

The embodiments shown in fig. 2-3 are explained in detail below by way of example 1 and example 2.

Example 1: and adding a push type for the current temperature value resource in the service equipment.

Before adding a push type to the current temperature value resource in the service device, the initial resource information of the current temperature value resource in the service device is as follows:

{"rt":[“oic.r.temperature”],

"if":["oic.if.s","oic.if.baseline"],

"temperature":20

}

step one, when a push synchronization mode needs to be added to the current temperature value resource in the service equipment, the service equipment is configured through configuration equipment. Alternatively, the configuration device may configure the service device in the following two ways.

One implementation is as follows:

the shadow device configuration resource is included in the service device (for example, the shadow device configuration resource may be oic.wk.shadow.conf), and is used to request that the shadow device is generated in the network device, and initially, the shadow device configuration resource is as follows:

{

service identifier of resource configured by ' si ', ' v/shadow device, initial value is null

"sgr" ",// URI of shadow device configuration resource, the initial value is null

"sgi"// generating an indication of a shadow device with an initial value of null

"pushproxy"// resource synchronization mode initial value is null

}

The configuration device may request to update the shadow device configuration resource in the service device, for example, the configuration device may request to update the resource synchronization mode attribute in the shadow device configuration resource, the service device may update the shadow device configuration resource according to the request sent by the configuration device, and the updated shadow device configuration resource is as follows:

{

"si" "Shadow _ Service _ ID"// Service identification of Shadow device configuration resource

"sgr": copies:// [ fe80:: b1d 6: 1111/oic/shadow/gen ",// URI of shadow device configuration resource

True,// generating an indication of a shadow device "sgi

"pushproxy"/resource synchronization mode, when the value is true, it means that the service equipment supports push synchronization mode

}

After the shadow device configuration resource in the service device is updated, when the service device requests the network device to generate the shadow device according to the shadow device configuration resource, the service device can obtain the location information of the current temperature value resource in the network device.

The other realization mode is as follows:

the service device includes a synchronization mode resource (for example, the resource type of the synchronization mode resource may be oic.r.shadow.synchronized), where the synchronization mode resource is used to indicate a synchronization mode of the resource, and initially, the synchronization mode resource is as follows:

{

"rt": oil.r.show. syncextended ",// synchronized resource type

"if" [ "oic.if.rw", "oic.if.baseline" ],// interface of synchronization mode resource

Rsm/resource synchronization mode attribute, initial value is null

}

The configuration device may request to update the synchronization mode resource in the service device, for example, the configuration device may request to update the resource synchronization mode attribute in the synchronization mode resource, and the service device may update the synchronization mode resource according to the request sent by the configuration device, where the updated synchronization mode resource is as follows:

{

"rt": oil.r.show. syncextended ",// synchronized resource type

"rsm"// resource synchronization mode attribute, when the value is pushproxy, it means that the service device supports push synchronization mode

}

After the synchronization mode resource in the service device is updated, when the service device requests the network device to generate the shadow device according to the synchronization mode resource, the service device can obtain the location information of the current temperature value resource in the network device.

And step two, the service equipment sends a configuration success response to the configuration equipment.

Step three, after the service device sends a configuration success response to the configuration device, the service device may add a push synchronization type and at least one attribute to the initial resource information of the current temperature value resource, where the at least one attribute includes a location attribute, a synchronization interface attribute, and a synchronization resource type attribute, and the updated initial resource information is as follows:

{"rt":[“oic.r.temperature”，"oic.r.pushproxy"],

"if":["oic.if.s","oic.if.baseline"],

"temperature":20,

"pushtarget":"",

"qif":[""],

"qrt":[""]

}

the values of the location attribute "pushtarget", the synchronization interface attribute "qif", and the synchronization resource type attribute "qrt" in the initial resource information after the above update are null.

Step four, the service equipment sends a shadow equipment generation request to the network equipment.

Optionally, the content included in the shadow device generation request may be as follows:

step five, the network device generates the shadow device according to the shadow device generation request, and generates the following resource information for the shadow device:

1: discovery resource/oic/res

2: platform resource/oic/p

3: replicated device resources/oic/d of service device

The/oic/d resource information is as follows:

4: device resource/oic/shadow/info of shadow device corresponding to service device

The/oic/shadow/info resource information is as follows:

5: resource information/temperature of copied current temperature value resource

The/temperature resource information is as follows:

step six, after the network device generates the shadow device, the network device sends a shadow device generation success response to the service device, and the content of the response may be as follows:

step seven, the service device assigns at least one attribute newly added in the initial information of the current temperature value resource according to the response received in the step six and the updated initial resource information in the step three to obtain the resource information of the current temperature value, wherein the resource information is as follows:

step eight, the configuration tool can configure the access authority of the shadow device.

When it needs to be described, the process of configuring the access right of the shadow device may refer to the prior art, and is not described herein again.

Step nine, when the current temperature detected by the service equipment (temperature sensor) is 25 degrees, the service equipment updates the resource information of the current temperature value resource obtained in the step seven as follows:

step ten, because the resource information of the current temperature value resource includes "oic.r.pushproxy", the service device sends the current temperature value resource to the network device according to the resource information, for example, the service device may send an update request to the network device through an "oic.if.s" interface, where the URI of the request to update the resource is maps:// [ fe80:: b1d 6:2222/temperature, and the update request may include the following latest expression of the current temperature value resource:

step eleven, the network equipment updates the resources at the positions of the maps:/[ fe80:: b1d 6:: 2222/temperature according to the update request, so that the current temperature value in the current temperature value resources in the network equipment is updated to 25 degrees.

Example 2: and adding a subscription type for the temperature range resource in the service equipment.

Before adding a subscription type to the temperature range resource in the service device, the initial resource information of the temperature range resource in the service device is as follows:

{"rt":[“oic.r.temperatureRange”],

"if":["oic.if.a","oic.if.baseline"],

"temperatureRange":[0,30]

}

step one, when a subscription synchronization mode needs to be added for temperature range resources in service equipment, the service equipment is configured through configuration equipment. Alternatively, the configuration device may configure the service device in the following two ways.

One implementation is as follows:

{

Observeproxy// resource synchronization mode, the initial value is null

}

{

True,// generating an indication of a shadow device "sgi

"observproxy": true,// resource synchronization mode, when the value is true, it means that the service device supports the subscription synchronization mode

}

After the shadow device configuration resource in the service device is updated, when the service device requests the network device to generate the shadow device according to the shadow device configuration resource, the service device can acquire the location information of the temperature range resource in the network device.

The other realization mode is as follows:

the service device includes a synchronization mode resource (for example, the synchronization mode resource may be oic.r.show.syncmethod), where the synchronization mode resource is used to indicate a synchronization mode of the resource, and initially, the synchronization mode resource is as follows:

{

"rt": oil.r.show. syncextended ",// synchronized resource type

Rsm/resource synchronization mode attribute, initial value is null

}

{

"rt", oil, r, show, sync, resource type,// sync, etc

"rsm"// resource synchronization mode attribute, when the value is observeproxy, it means that the service equipment supports the subscription synchronization mode

}

After the synchronization mode resource in the service device is updated, when the service device requests the network device to generate the shadow device according to the synchronization mode resource, the service device may obtain the location information of the temperature range resource in the network device.

After the service device sends the configuration success response to the configuration device, a subscription synchronization type and at least one attribute are added to the initial resource information of the temperature range resource, wherein the at least one attribute comprises a position attribute, a synchronization interface attribute and a synchronization resource type attribute, and the updated initial resource information is as follows:

the values of the location attribute "observetarget", the synchronization interface attribute "qif", and the synchronization resource type attribute "qrt" in the initial resource information after the above-described update are null.

1: discovery resource/oic/res

2: platform resource/oic/p

3: replicated device resources/oic/d of service device

The/oic/d resource information is as follows:

The/oic/shadow/info resource information is as follows:

5: resource information/temperature range of replicated temperature range resources

The/temporal range resource information is as follows:

step six, after the network device generates the shadow device, the network device sends a successful response of the shadow device generation to the service device, and the content of the response may be as follows:

step seven, the service device assigns at least one attribute newly added in the initial information of the temperature range resource according to the response received in the step six and the updated initial resource information in the step three to obtain the resource information of the current temperature value, wherein the resource information is as follows:

Step nine, the service equipment sends a subscription request to the network equipment.

Since the resource information of the temperature range resource of the service device includes "oic.r.observeproxy", the service device sends a subscription request to the network device according to the resource information, so as to request to observe the temperature range resource corresponding to the shadow device of the service device in the network device.

For example, the service device may send a subscription request to the network device through an "oic.if.a" interface, the operation mode of the service device requesting the observed temperature range resource may be reading, the target resource of the reading request is a temperature range resource copied on the network device, and the URI of the request is the URI of the temperature range resource: maps:// [ fe80:: b1d6]:2222/temperature range.

Step ten, the network equipment receives the subscription request of the service equipment.

Optionally, the network device may send a first subscription response to the serving device, where the first subscription response indicates that the network device accepts the subscription request of the serving device.

Step eleven, when the user adjusts the temperature range resource in the network device through the client device, for example, the temperature range is adjusted to [10,20], then the resource information of the latest temperature range resource in the network device is as follows:

and step twelve, the network equipment sends the temperature range resource to the service equipment according to the resource information of the temperature range resource.

Optionally, the network device may send a second subscription response to the service device, where the second subscription response includes the updated resource information of the temperature range resource, and the updated resource information of the temperature range resource is shown in the resource information in step eleven.

Step thirteen, the service equipment updates the resource at the locations of maps:// [ fe80:: b1d 6:: 2222/temporal range according to the update request, so as to realize the update of the temperature range in the temperature range resource in the service equipment to [10,20 ].
