Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
The technical solution of the embodiment of the present invention can be implemented in a system including a management device and at least one hardware resource. For example, a unified Machine-to-Machine (oneM 2M) system, a Machine-to-Machine (M2M) system, etc.
For convenience of understanding and description, the following description illustrates, by way of example and not by way of limitation, implementation procedures and actions of the method and apparatus for matching resources in the oneM2M system according to embodiments of the present invention.
It should be understood that in the oneM2M system, the process of "semantically labeling" the resource may be regarded as an example of a method of "matching the resource" according to an embodiment of the present invention.
Correspondingly, a semantic engine in the oneM2M system, a Common Service Entity (CSE) or a Common Service Function CSF (CSF) of a Function module of the CSE, etc. may be considered as an example of the management device in the embodiment of the present invention. "class" is an example of "control information set" in the embodiment of the present invention, and "AE" is an example of "hardware resource" in the embodiment of the present invention.
The terminal device may be a User terminal, a mobile device, a wireless communication device, a User Equipment or User Equipment (UE), a handheld device having wireless local area network (e.g., Wi-Fi) communication capability, a computing device, or other processing device connected to a wireless modem.
FIG. 1 shows a schematic architecture diagram of a unified machine to machine system according to an embodiment of the invention. As shown in fig. 1, the oneM2M system is divided into an application layer, a common service layer, and a network service layer. Wherein, the Application layer provides the Application logic of the oneM2M solution from end to end by an Application Entity (AE). The Common service layer is managed by a Common Service Entity (CSE) and is responsible for aggregating application layer information to form a resource pool, and meanwhile, coordinating underlying network transmission, a core layer in oneM2M plays a role of a platform, and the Common service layer comprises a series of instantiated Common service functions. The Network layer is managed by a Network Service Entity (NSE) and is responsible for the transmission of the underlying Network, and provides the capability which can be provided by the underlying Network for the public service layer.
Under the oneM2M system, there are 3 communication interfaces (also called reference points) between layers, where the Mca reference point is the interface between AE and CSE and is responsible for communication from AE to CSE or from CSE to AE; the Mcc reference point or Mcc' reference point is an interface between two CSEs and is responsible for communication between the CSEs; the Mcn reference point is the interface between the CSE and NSE, and is responsible for CSE to NSE or NSE to CSE communications.
It should be understood that all entities in oneM2M system, such as AE, CSE, data, etc., may be represented in the form of resources. The resource structure defines in detail the way resources are represented and the way resources are acquired, which are individually addressable.
In the prior art, semantic annotation is a method for adding semantic information to a resource, and after adding semantics to the resource, an application program can know data contained in the resource and meanings of the data. Simply, through semantic annotation, consistent data translation can be provided for resources, data interoperation between heterogeneous applications can be achieved, and the resources added with the semantic annotation can be sensed and controlled by an application which knows what data and data meaning are provided.
Fig. 2 shows a schematic diagram of semantic annotation in oneM2M system. When a hardware device is registered as a hardware resource in the oneM2M system, the hardware resource is registered as AE without loss of generality. At this time, the semantic engine in oneM2M system starts related functions, and for the AE to find the closest ontology in the ontology library of oneM2M system, the ontology becomes the reference ontology of the AE. The ontology includes concepts such as classes, operations, and the like, and relationships between the concepts, and more precisely, AE refers to the classes in the ontology. For example, as shown in FIG. 2, the semantic engine finds the closest ontology A for an AE, which becomes the reference ontology for the AE, and more specifically, the AE references class B in ontology A. According to the resource structure in the oneM2M system, the ontology of the AE records a Universal Resource Identifier (URI) of class B by referring to the ontologyRef value, and the semantic description corresponding to the AE is also described according to class B. By semantically labeling the AE, the hardware device corresponding to the AE can be controlled by the semantic command of the oneM2M system.
However, if the reference ontology a of the AE changes, for example, a subclass D is added below class B. If the AE is an instance that is closer to class D, that is, class D provides more attributes, data or operations, etc. that the hardware device can support. If the oneM2M system cannot provide a synchronous update mechanism of semantic annotation, at this time, the ontologyRef value of the AE still holds the URI of class B, and the semantic description of the AE is still obtained according to B, so that the operation, attribute or data and the like newly provided by class D and provided by class B cannot be used through a semantic command, and the user experience is not good enough.
For ease of understanding, the above problems are exemplified. Assume that a light with adjustable brightness is installed in the bedroom. Whether registered with oneM2M platform or not, we can adjust its brightness by physical key or knob of the lamp, etc. At this time, if the lighting module is registered as a resource on the oneM2M platform supporting semantics, the model of the lighting on the platform only has simple operations of turning on/off, so we can only turn on/off the lighting through the semantics platform, but cannot adjust the brightness of the lighting. If a lamp model is newly added to the platform, the lamp model comprises both on/off operation and brightness adjustment operation, but during registration, the lamp in the bedroom is already corresponding to the model only with the on/off operation, and if the corresponding relation cannot be updated in time, the brightness adjustment service of the lamp still cannot be acquired through the semantic platform.
The method for matching resources according to the embodiment of the present invention is described in detail below with reference to fig. 3 to 6.
Fig. 3 shows a schematic flow chart of a method 100 of matching resources according to an embodiment of the invention. As shown in fig. 3, the method 100 includes:
s110, the management device acquires a second control information set, wherein the control information included in the second control information set is different from the control information included in the first control information set;
s120, the management device performs a re-matching process on the target hardware resource according to the second control information set, so that the target hardware resource is matched with the second control information set.
According to the embodiment of the present invention, the management device performs the re-matching process on the target hardware resource by acquiring the second control information set different from the first control information set matched with the target hardware resource, and according to the second control information set, so that the target hardware resource is matched with the second control information set. Then, through the terminal device, according to the control information in the second control information set, the relevant data and attributes of the hardware device corresponding to the target hardware resource can be obtained or the relevant operation on the hardware device can be executed to control the hardware device, so that the exertion of the hardware resource function can be improved, and the user experience can be improved.
It should be understood that, in the embodiment of the present invention, the "first control information set" and the "second control information set" are only used for distinguishing different control information sets, and do not set any limit to the scope of the embodiment of the present invention.
The control information included in the second control information set may include a part of or all of the control information different from the control information included in the first control information set.
Specifically, in the embodiment of the present invention, three ways of acquiring the second control information set are provided, which are way 1, way 2, and way 3, respectively. For convenience of explanation, the above three modes are described in detail below.
Mode 1
Optionally, the system further comprises an external server for providing the set of control information to the management device, in which external server the reference integrity refComplete attribute value of each of the hardware resources is stored, wherein,
if the refComplete value of the first hardware resource is the first preset value, the external server can determine that the updated control information set needs to be sent to the management device after the control information set matched with the first hardware resource is updated according to the refComplete value;
if the refComplete value of the first hardware resource is the second preset value, the external server can determine that the updated control information set does not need to be sent to the management device after the control information set matched with the first hardware resource is updated according to the refComplete value,
and, the method further comprises:
when the management device determines that the second control information set includes all control information that the target hardware resource can support, sending first indication information to the external device, where the first indication information is used to indicate the external device to set a refComplete value of the target hardware resource to the second preset value; or
When the management device determines that the second control information set does not include all control information that the target hardware resource can support, sending second indication information to the external device, where the second indication information is used to instruct the external server to set the refComplete value of the target hardware resource to the first preset value.
In the embodiment of the present invention, the system creates a new attribute for the hardware resource, that is, a refComplete attribute, where the refComplete value is used to indicate whether the hardware resource completely matches with the currently matched control information set. In other words, the refComplete value of a hardware resource indicates whether the current matching control information set of the hardware resource includes all the control information that the hardware resource can support. If the control information set includes all the control information that the hardware resource can support, it can also be said that the hardware resource and the control information set are completely matched; if the control information set includes part, but not all, of the control information that the hardware resource can support, it can also be said that a complete match between the hardware resource and the control information set is not achieved.
Specifically, the refComplete value of the hardware resource a (i.e., an example of the hardware resource) indicates whether the hardware resource a completely matches the currently matched control information set M (i.e., an example of the first control information set), so that when the control information set in the system is changed, the external server can determine whether the attribute information of the hardware resource a needs to be transmitted to the management device through the refComplete value of the hardware resource a, so that the management device can compare the attribute information of the hardware resource a with the changed control information set and determine whether the hardware resource a needs to be re-matched. Obviously, if a hardware resource has already been completely matched, even if there is a change in the control information set in the system, for the hardware resource, since all the control information is already included in the currently matched control information set, the terminal device is used, and the parameters, data, attributes, and the like of the hardware device can be controlled or obtained through the control information in the first control information set, so that the hardware resource does not need to be re-matched. Correspondingly, if a hardware resource is not completely matched, when a control information set in the system is changed, the management device needs to judge whether there is control information that the hardware resource can support but the current matched control information set does not have in the changed control information set, if so, the management device needs to change the matching relationship of the hardware resource and re-match the hardware resource, so that more functions of the hardware device can be used through the terminal device.
It should be understood that, in the embodiment of the present invention, the first preset value is used to indicate that the hardware resource does not completely match the currently matching control information set, and the second preset value is used to indicate that the hardware resource completely matches the currently matching control information set.
It should also be understood that, in the embodiment of the present invention, the refComplete attribute is applied to the re-matching process, but the management device may also use the refComplete attribute when the resource is first matched, thereby improving the efficiency of the re-matching.
It should be noted that the first preset value and the second preset value may be one value, or may be in other forms based on a preset rule, and the present invention is not limited thereto.
Therefore, in the embodiment of the present invention, by creating the refComplete attribute for the hardware resource, when the management device determines whether the hardware resource needs to be re-matched, the efficiency of determination is improved.
Hereinafter, the method for matching resources according to an embodiment of the present invention described in equation 1 will be described in detail, taking the oneM2M system as an example and not as a limitation.
FIG. 4 shows a schematic interaction diagram of a method of matching resources according to an embodiment of the invention. The oneM2M system in fig. 4 includes an external server, a semantic engine, a generic service entity. As shown in fig. 4, the method includes:
s201, the semantic engine subscribes to the reference ontology of the AE.
It should be understood that an AE herein refers to an AE for which a perfect match has not been achieved, for which the semantic engine no longer needs to subscribe to the reference ontology of that AE.
For example, if the refComplete attribute value of the first AE (i.e., an example of AE) is 0, the semantic engine subscribes to the reference ontology of the AE, and the semantic engine knows the reference ontology once it is changed.
S202, a new class is added below the reference ontology.
For example, class A below the reference ontology adds a new subclass B.
S203, the external server sends the related attributes of the AE and the related attributes of the new class to a semantic engine.
It should be understood that the related attributes of the above-mentioned AEs refer to the "store local resource links" attribute of the AE. An AE corresponding to each hardware device in the oneM2M system has a local resource pointed to by the content attribute of the AE.
S204, the semantic engine returns a response message to the external server.
S205, the semantic engine analyzes whether the AE needs synchronous semantic annotation, and further judges whether the new class can realize complete semantic annotation to the AE if the AE needs to be synchronous.
Specifically, the semantic engine determines whether or not a re-matching process for the AE is necessary, and actually determines whether or not the AE is an instance of the new class. More specifically, the semantic engine compares the local resource pointed to by the content attribute with the new class to determine whether a re-matching process for the AE is required to match the AE with the new added class. If the AE is an instance of the new added class, the AE is re-matched so that the AE is matched with the new class, and further, the semantic engine judges whether the new added class can be used for completely semantically labeling the AE. If the complete semantic annotation can be realized, the semantic engine sends first indication information to an external server, and the external server sets the refComplete value of the AE to be 1; if the new class can not realize the complete semantic annotation of the AE, the semantic engine sends second indication information to an external server, and the external server sets the refComplete value of the AE to 0, so that when the reference body of the AE is changed, the semantic engine performs the re-matching on the AE again.
S206, the semantic engine sends a re-matching request to the general service entity, where the re-matching request is used to change the ontology reference ontologyRef value of the AE.
Specifically, the semantic engine determines that if the AE is an instance of the new class, the ontologyRef value of the AE is changed to the URI of the new class.
S207, the general service entity sends a response message to the semantic engine.
S208, the semantic engine sends a sub-resource updating request message to the general service entity, wherein the sub-resource updating request message is used for requesting to update the attribute of the related sub-resource of the AE;
specifically, attributes of related sub-resources of the AE are updated, including updating the AE sub-resource containers continainer and contentInstance. According to the resource structure in oneM2M system, the child resources contiainer and contentInstance of AE each have an ontologyRef attribute, and the ontologyRef value of contiainer and the ontologyRef value of contentInstance are consistent with the ontologyRef value of the associated AE unless otherwise specified. Therefore, in the embodiment of the present invention, after the ontogyref attribute value of the AE is updated, the ontogyref values of the child resources continainer and contentInstance thereof also need to be updated, that is, the updated ontogyref value of the AE is consistent with the updated ontogyref value of the AE.
S209, the universal service entity returns a response message to the semantic engine;
s210, if the refComplete attribute value of the AE is 1, the semantic engine cancels the subscription of the reference ontology of the AE;
s211, the terminal device then sends a semantic request to the oneM2M system, where the semantic request is used to execute a relevant operation on the hardware device corresponding to the AE.
It should be understood that, in the embodiment of the present invention, the refComplete attribute values are only illustrated as 0 and 1, and the present invention is not limited thereto. For example, the refComplete attribute value may be other values based on convention, or other forms, etc.
In the method 1, the semantic engine may subscribe the reference ontology of the hardware resource that has not yet reached the complete matching through the refComplete attribute created by the system for the hardware resource, so that the change information may be obtained when the reference ontology is changed, and it is determined whether to perform the re-matching processing on the hardware resource according to the change information.
Therefore, according to the method for matching resources in the embodiment of the present invention, the efficiency of matching can be improved by creating a refComplete attribute for a hardware resource in the system.
Mode 2
Optionally, the acquiring, by the management device, the second control information set includes:
the management device determining the first set of control information;
the management device determining whether the first set of control information is updated;
