Description

Method and device for intercommunication between M2M system and identification analysis system

Technical Field

The invention relates to the technical field of Internet of things, in particular to a method and a device for intercommunication between an M2M system and an identification analysis system.

Background

Machine-to-Machine Communications (M2M) is a networked application and service with Machine intelligent interaction as a core, and realizes data communication without manual intervention by embedding a wireless or wired communication module and application processing logic in a Machine, so as to meet the informatization requirements of users on monitoring, command scheduling, data acquisition and measurement and the like.

The internet of things identifier is used for identifying and distinguishing different physical and logical entities and information resources, and is the basis and the premise for realizing machine communication. The Internet of things identification comprises a virtual identification and a physical identification, and the Internet of things general system architecture of the international telecommunication union in the published ITU-T Y.2221 is divided into three layers, namely a perception layer, a network layer and an application layer, wherein each layer has a corresponding identification. Different from an identification service technology of the internet, firstly, identification types covered in the internet of things are more, and currently, the mainstream internet of things identification system at home and abroad comprises EPC, Handle, OID, Ecode, uCode, mRFID and the like. Secondly, the application scene is more complex, and different identification systems are adopted for different application fields. In addition, the internet only uses the mapping between the application identifier and the communication identifier, for example, the mapping between the domain name and the IP address is implemented by using DNS, and the internet of things needs to be extended on the basis of this, so as to implement the mapping between the object identifier, the communication identifier, and the application identifier. For example, EPCglobal, the largest RFID standardization organization in the world, is currently, and its proposed ONS (Object Name Service) is an internet of things identification resolution Service implemented by using the existing DNS protocol in the internet. However, the ONS service only supports the item id of a single coding standard, i.e. EPC code, and cannot resolve the item id of other identification systems. For another example, the Handle System and the uCodeRP are third party identifier parsing systems for Handle and uCode identifier types, respectively. Therefore, in order to promote interconnection and intercommunication among internet of things applications using different identification systems and combine the requirements of intelligence and real-time performance of the M2M system, an M2M platform capable of realizing interconnection with various third-party identification analysis systems and a method for providing identification discovery compatible with various types of identifications are needed.

However, the existing internet of things third party identifier resolution system only supports single internet of things identifier query, is not compatible with other various internet of things identifier queries, is difficult to intercommunicate among various third party identifier resolution systems, cannot support identification of heterogeneous identifiers at present, cannot intercommunicate with resolution systems such as ONS and Handle systems, and is difficult to meet the condition that different identifier systems are adopted for intercommunicating in different applications or the same application.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

Referring to fig. 1, the present invention provides a method for interworking an M2M system and an identity resolution system, where the method is performed at a side of a common service entity. In a specific embodiment, the method specifically includes the following steps:

s11, according to the identification discovery request containing the identification code of the object identification sent by the received identification query entity, when the information corresponding to the object identification is queried in the resource in the identification discovery request fails, the identification discovery request is sent to the interworking entity.

In the embodiment of the present invention, the third party identifier resolution system needs to complete registration on the M2M system first to perform interworking with the M2M system. The M2M system of the present invention includes a common service entity, the interworking entity, and the identity query entity.

Referring to fig. 2, fig. 2 shows a functional block diagram of a third party identity resolution system registered with an M2M system. In one possible design, the present invention preferably implements the registration of the third party identifier resolution system on the M2M system by the following method:

and firstly, the third party identification analysis system is registered on the interworking entity.

And secondly, the interworking entity registers on the public service entity.

Specifically, the third party identifier resolution system may perform registration actively by the third party identifier resolution system or may perform discovery by the interworking entity when registering on the interworking entity. The third party identification analysis system sends a registration request to the interworking entity, and the interworking entity creates first resource information for the third party identification analysis system after receiving the registration request so as to complete registration.

Further, the interworking entity registers after discovering the third party identifier resolution system, for example, the interworking entity may manually register through the third party identifier resolution system. The communication with the third party identifier resolution system can be actively realized through the pre-configuration information of the interworking entity, or through some means for device discovery, which is not described herein any more since the part belongs to the prior art.

Further, the interworking entity includes an interaction module and a resource management module. The interaction module mainly provides an interface which is communicated with each third-party identification analysis system. Each third party identification analysis system is provided with a corresponding interface unit. The interaction module can call the information in the first resource information in the resource management module to assist in completing analysis and other operations. In addition, the interactive module also has an identity authentication function and carries out identity authentication on the interactive third-party identification analysis system. The resource management module is used for creating the first resource information for different third party identification analysis systems after the third party identification analysis systems are found.

Specifically, the establishing, by the interworking entity, the first resource information for the third party identifier resolution system through the resource management module after receiving the registration request sent by the third party identifier resolution system specifically includes:

the interaction module carries out identity verification on the third party identification analysis system;

and when the verification is passed, the interaction module sends a message passing the verification to the resource management module, so that the resource management module creates first resource information for the third-party identification analysis system.

Wherein the first resource information includes:

(1) the identification types supported by each third-party identification analysis system;

(2) the preset interaction rules supported by each third-party identification analysis system;

(3) and the mapping relation list of the address information and the object identification is obtained after the mapping relation list is analyzed by each third-party identification analysis system. The three resource information are specifically as follows:

(a) the identification types supported by the third-party identification resolution system are as follows: the method is used for representing the identification systems supported by each third-party identification analysis system, such as different identification systems of epc, handle, oid, ucode, mcode, and ecode.

Specifically, different third-party identifier parsing systems correspond to different identifier types, for example, a handle system corresponds to a handle identifier type, and the object identifier with the identifier type of handle may be parsed.

(b) The preset interaction rule supported by the third party identification analysis system comprises at least one of the following items: the identification of the corresponding interface of each third party identification analysis system, the communication protocol supported by each third party identification analysis system and the address identification of each third party identification analysis system.

The identifier of the interface corresponding to the third-party identifier resolution system, such as a flag parameter, is used for identifying the interface unit corresponding to each third-party identifier resolution system in the interaction module through the flag parameter. For example, the flag definition integer field '01' corresponds to the ONS interface element and '02' corresponds to the Handle system interface element. Optionally, an address identification of the interface unit may be provided.

The communication protocols supported by the third-party identifier resolution system, such as protocol parameters, are used for characterizing the communication protocols supported by or supported by each third-party identifier resolution system, for example, HTTP, CoAP, and the like.

The parameter is used to characterize the address id of the third party id resolution system, such as severAddr.

In addition, for example, a validaxexpression parameter, by which it is verified whether the object id meets the specification format requirement.

(c) And the mapping relation list of the address information and the object identification is obtained after the mapping relation list is analyzed by each third-party identification analysis system.

Specifically, for the object identifier which has been subjected to identifier analysis by the third-party identifier analysis system, a mapping relationship is established between the object identifier and the address information obtained after identification, and the object identifier is stored to generate the mapping relationship list, so that the object identifier can be directly obtained from the mapping relationship list when the same object identifier is subsequently queried, and the analysis operation by the third-party analysis system is not required.

Further, the interworking entity needs to ensure the accuracy of the mapping relationship list and perform timely maintenance. In one possible design, the manner of updating and maintaining the mapping relationship list according to the present invention may include, but is not limited to, the following two ways:

1. the interworking entity sends a mapping relation type verification request to the third party identification analysis system according to a preset time period, and updates the mapping relation list according to the received verification result fed back by the third party identification analysis system;

2. and the interworking entity receives the change message of the address information sent by the third-party identification analysis system and updates the mapping relation list according to the change message. For example, the update may be maintained by subscribing to a notification, specifically, subscribing to information of a specific object identifier in the third party identifier resolution system, and when the address information storing information corresponding to the object identifier changes, the third party identifier resolution system sends a change message to the interworking entity.

Further, when the interworking entity registers on the public service entity, by sending a resource creation request to the public service entity, after receiving the resource creation request, the public service entity creates second resource information for the interworking entity in response to the resource creation request, where the second resource information includes a resource used for storing information of each third-party identifier resolution system and an identifier type supported by each third-party identifier resolution system.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a structure of creating resources of the interworking entity in the common service entity according to the present invention. As shown in fig. 3, the interworking entity registers with the common service entity, and creates the second resource information in the common service entity through a creation operation. Specifically, the second resource information includes a resource for storing information of each third-party identifier resolution system and an identifier type supported by each third-party identifier resolution system.

The registration operation of the third-party identification analysis system is completed, and the subsequent interactive identification discovery process with the interworking entity can be realized after the registration of the third-party identification analysis system is completed.

Specifically, the interworking method of the M2M system and the identifier resolution system of the present invention realizes interworking between the M2M system and the third party identifier resolution system through the process of identifier discovery. When the method of the invention realizes the identification discovery, the identification discovery request is sent to the public service entity through the identification query entity. After receiving the identifier discovery request, the public service entity identifies the identifier type corresponding to the object identifier through a heterogeneous identifier identification function; and the public service entity judges whether the resources in the public service entity contain information corresponding to the object identifier, if so, the identifier type is added into the identifier discovery request and then is sent to the interworking entity.

It should be noted that, in this embodiment of the present invention, the identifier discovery request includes a resource filtering parameter, where the resource filtering parameter includes an identifier of an object identifier and a filtering function parameter, and the filtering function parameter may be configured to indicate that the identifier discovery request is forwarded to the interworking entity. When the identifier query entity sends the identifier discovery request to the public service entity, resource filtering parameters in the identifier discovery request can be preset, and different setting parameters lead to different subsequently adopted identifier discovery schemes.

In the embodiment of the present invention, the identifier discovery request includes a parameter setting corresponding to an identifier code of the object identifier. Furthermore, in another embodiment of the present invention, the method further comprises setting a filtering function parameter, wherein the filtering function parameter is configured to instruct forwarding the identifier discovery request to the interworking entity. Specifically, the present invention preferably presets the parameters in the identifier discovery request according to the following two schemes:

and in the first scheme, the identification code of the object identifier in the resource filtering parameter is set, and the filtering function parameter is set.

Specifically, the public service entity receives the identifier discovery request sent by the identifier querying entity, where the identifier discovery request adopts a RETRIEVE operation, and sets a resource filtering condition in a Filter criterion parameter in the request information, where the resource filtering condition includes setting an attribute to "object identifier information, for example," object identifier information, identity information { object identifier identity of an object identifier is 1.2.156.20000.201031 }. And sets a filter function parameter filterUsag to "indicate forwarding the identity discovery request to the interworking entity IPEOnDemandDiscovery".

And a second scheme of setting only the identification code of the object identifier in the resource filtering parameters, specifically, the identifier discovery request adopts a RETRIEVE operation, and the identifier discovery request includes an identification code tandibleid parameter of the object identifier requested to be discovered.

S12, receiving an analysis result obtained by the interworking entity to a third party identification analysis system according to a preset interaction rule, wherein the analysis result comprises address information of information corresponding to the object identification.

In the embodiment of the present invention, after receiving the identifier discovery request sent by the public service entity, the interworking entity queries whether address information corresponding to the object identifier is stored in a resource therein. According to different parameter settings in the identifier discovery request, the method for querying the interworking entity is correspondingly different, and the specific querying method is as follows:

referring to fig. 4, fig. 4 is a schematic block diagram illustrating an implementation of an identifier query in an interworking method between an M2M system and an identifier resolution system according to an embodiment of the present invention. In this embodiment, the parameter setting in the identity discovery request takes the first scenario in step S11.

Specifically, after receiving the identifier discovery request, the advertisement service entity queries whether the resource stores address information corresponding to the object identifier, and if not, checks whether the filtering function parameter in the identifier discovery request is set to "indicate to forward the identifier discovery request to the interworking entity", and if so, adds the identifier code of the object identifier and the identifier type corresponding to the object identifier to the identifier discovery request and forwards the identifier discovery request to the interworking entity.

Further, after receiving the identifier discovery request sent by the public service entity, the interworking entity queries whether an instance resource therein contains address information corresponding to the object identifier, where the directory instance resource is the first resource information created by the interworking entity according to the address information obtained by the interworking entity in history.

Further, if the instance resource does not contain the address information corresponding to the object identifier, the interworking entity calls the preset interaction rule to send an identifier resolution request containing the object identifier to an identifier resolution server corresponding to the third-party identifier resolution system through the interaction module according to the identifier type of the object identifier;

and after receiving the analysis result correspondingly fed back by the identification analysis server, the interworking entity creates a new instance resource under the resource of a corresponding third-party external analysis system so as to store the mapping relation between the object identification and the address information in the analysis result.

Referring to fig. 5, fig. 5 is a schematic block diagram illustrating an implementation of an identifier query in an interworking method between an M2M system and an identifier resolution system according to another embodiment of the present invention. In this embodiment, the parameter setting in the identifier discovery request takes the second scenario in step S11.

Specifically, after receiving the identifier discovery request, the advertisement service entity queries whether the resource stores address information corresponding to the object identifier, and if not, forwards the identifier discovery request to the interworking entity after adding the identifier of the object identifier and the identifier type corresponding to the object identifier.

Further, after receiving the identifier discovery request sent by the public service entity, the interworking entity queries whether a mapping relationship table therein contains address information corresponding to the object identifier.

Further, if the mapping relation table does not contain address information corresponding to the object identifier, the interworking entity calls the preset interaction rule to send an identifier resolution request containing the object identifier to an identifier resolution server corresponding to the third-party identifier resolution system through the interaction module according to the identifier type of the object identifier;

and the interworking entity receives the analysis result correspondingly fed back by the identification analysis server and then feeds back the analysis result to the public service entity.

For example, if the identifier type of the object identifier is handle, the interaction module invokes an interaction unit corresponding to the identifier type of handle defined in the flag parameter in the first resource information and invokes a communication protocol supported by a third-party identifier resolution system supporting the identifier type of handle defined in the protocol parameter to communicate with the third-party identifier resolution system.

Specifically, the interaction module sends an identifier analysis request including an object identifier to a server corresponding to the handle system through a communication protocol supported by the handle system, the server analyzes the object identifier after receiving the identifier analysis request and feeds back an analysis result, and the analysis result includes address information used for storing information corresponding to the object identifier.

And S13, feeding back the address information to the identification query entity.

In the embodiment of the present invention, after receiving the address information, the interaction module sends the address information to the public service entity through the interworking entity, and after receiving the address information, the public service entity feeds the address information back to the identifier query entity, so as to complete the response to the identifier discovery request, and implement the interworking between the M2M system and the third party identifier resolution system.

In one embodiment, after the third-party identifier parsing system receives the identifier parsing request corresponding to the identifier discovery request, the examples of the input and output values are as follows:

(1) for ONS system

Input values are as follows: EPC code, EPC-64II format type, a string of bits

【10.010001001011101.0011010001101.0000000110000000000000001100001101】

And (3) outputting: ip address, 10.101.101.193

And the output ip address is the address information used for storing the information corresponding to the object identifier in the analysis result.

(2) For Handle system

Input format, pre/suf, for example: 86.1000.11/70140703307739

And (3) output format: handle value set, for example:

referring to fig. 4, the present invention further provides an interworking apparatus between an M2M system and an identity resolution system, which in one embodiment includes an identity query entity, a public service entity 12 and an interworking entity 13, wherein,

and the identification query entity is used for sending an identification discovery request containing the identification code of the object identification to a public service entity and receiving the information corresponding to the object identification correspondingly fed back by the public service entity.

In this embodiment of the present invention, the identification query entity is an application entity in the M2M system. The application entity of the M2M system is an entity in the application layer that implements the M2M application service logic. Each application service logic may reside in multiple M2M nodes and/or on a single M2M node multiple times. Each execution instance of the application service logic is referred to as an "application entity" and is identified by a unique AE-ID.

In the embodiment of the invention, the identification query entity sends an identification discovery request to the public service entity and receives an identification discovery result correspondingly fed back by the public service entity. The public service entity specifically includes, when executing a query:

inquiring whether the local resource stores the information corresponding to the object identification;

if not, sending the identification discovery request to the interworking entity;

after receiving the identifier discovery request, the interworking entity firstly inquires whether the resource information of the interworking entity contains information corresponding to the attribute identifier;

if not, sending an analysis request corresponding to the object identifier to a third-party identifier analysis system;

after receiving the analysis request, the third party identification analysis system analyzes the object identification and feeds back the analyzed address information to the interworking entity;

the intercommunication entity sends the address information to the public service entity so that the public service entity can acquire the information of the object identification object stored in the address information;

and the public service entity sends the information corresponding to the object identifier to the identifier discovery request so as to complete the response of the request.

In the embodiment of the present invention, the identifier discovery request includes a parameter setting corresponding to an identifier code of the object identifier. Furthermore, in another embodiment of the present invention, the method further comprises setting a filtering function parameter, wherein the filtering function parameter is configured to instruct forwarding the identifier discovery request to the interworking entity. When the identifier query entity sends the identifier discovery request to the public service entity, resource filtering parameters in the identifier discovery request can be preset, and different setting parameters lead to different subsequently adopted identifier discovery schemes.

Specifically, the present invention preferably presets the parameters in the identifier discovery request according to the following two schemes:

and in the first scheme, the identification code of the object identifier in the resource filtering parameter is set, and the filtering function parameter is set.

Specifically, the public service entity receives the identifier discovery request sent by the identifier querying entity, where the identifier discovery request adopts a RETRIEVE operation, and sets a resource filtering condition in a Filter criterion parameter in the request information, where the resource filtering condition includes setting an attribute to "object identifier information, for example," object identifier information, identity information { object identifier identity of an object identifier is 1.2.156.20000.201031 }. And sets a filter function parameter filterUsag to "indicate forwarding the identity discovery request to the interworking entity IPEOnDemandDiscovery".

And a second scheme of setting only the identification code of the object identifier in the resource filtering parameters, specifically, the identifier discovery request adopts a RETRIEVE operation, and the identifier discovery request includes an identification code tandibleid parameter of the object identifier requested to be discovered.

And the public service entity 12 is configured to send the identifier discovery request to the interworking entity when querying information corresponding to the object identifier in the resource of the identifier discovery request fails according to the identifier discovery request, and feed back information corresponding to the object identifier pointed by the parsing result to the identifier querying entity after obtaining the information corresponding to the object identifier pointed by the parsing result according to the received parsing result obtained by the interworking entity.

In the embodiment of the present invention, the common service entity represents an instantiation of a set of "common service functions" in an M2M environment. The content of the main execution of the public service entity is as follows:

receiving the identification discovery request sent by the identification query entity, and identifying the identification type corresponding to the object identification through a heterogeneous identification function;

and judging whether the resources contain information corresponding to the object identifier, if not, adding the identifier type to the identifier discovery request, and then sending the identifier discovery request to the interworking entity.

Specifically, the identifier discovery request includes a resource filtering parameter, where the resource filtering parameter includes an identifier of an object identifier and a filtering function parameter, and the filtering function parameter may be configured to indicate that the identifier discovery request is forwarded to the interworking entity.

Further, when the identifier discovery request sets an identifier of an object identifier in the resource filtering parameter and sets the filtering function parameter, the filtering function parameter is configured to indicate that the identifier discovery request is forwarded to the interworking entity. And the public service entity judges whether the resource contains information corresponding to the object identifier, if not, inquires whether the filtering function parameter in the identifier discovery request is set to indicate to forward the identifier discovery request to the interworking entity, and if so, adds the identifier type to the identifier discovery request and then sends the identifier discovery request to the interworking entity.

And the interworking entity 13 is configured to obtain an analysis result from the third-party identifier analysis system according to a preset interaction rule, and send the analysis result to the public service entity, where the analysis result includes address information of information corresponding to the object identifier.

In the embodiment of the present invention, the interworking entity mainly executes the following contents:

(1) creating the first resource information and the second resource information of a third party identifier analysis system to complete the registration of the third party identifier analysis system;

(2) and the system is communicated with a third-party identification analysis system to complete the analysis of the object identification.

In the embodiment of the present invention, the third party identifier resolution system needs to complete registration on the M2M system first to perform interworking with the M2M system.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating a structure of a third party identity resolution system registered on an M2M system. In one possible design, the present invention preferably implements the registration of the third party identifier resolution system on the M2M system by the following method:

and firstly, the third party identification analysis system is registered on the interworking entity.

And secondly, the interworking entity registers on the public service entity.

Specifically, the third party identifier resolution system may perform registration actively by the third party identifier resolution system or may perform discovery by the interworking entity when registering on the interworking entity. The third party identification analysis system sends a registration request to the interworking entity, and the interworking entity creates the first resource information for the third party identification analysis system after receiving the registration request so as to complete registration.

Further, the interworking entity registers after discovering the third party identifier resolution system, for example, the interworking entity may manually register through the third party identifier resolution system. The communication with the third party identifier resolution system can be actively realized through the pre-configuration information of the interworking entity, or through some means for device discovery, which is not described herein any more since the part belongs to the prior art.

Further, the interworking entity includes an interaction module and a resource management module. The interaction module mainly provides an interface which is communicated with each third-party identification analysis system. Each third party identification analysis system is provided with a corresponding interface unit. The interaction module can call the information in the first resource information in the resource management module to assist in completing analysis and other operations. In addition, the interactive module also has an identity authentication function and carries out identity authentication on the interactive third-party identification analysis system. The resource management module is used for creating the first resource information for different third party identification analysis systems after the third party identification analysis systems are found.

Specifically, the establishing, by the interworking entity, the first resource information for the third party identifier resolution system through the resource management module after receiving the registration request sent by the third party identifier resolution system specifically includes:

the interaction module carries out identity verification on the third party identification analysis system;

and when the verification is passed, the interaction module sends a message passing the verification to the resource management module, so that the resource management module creates first resource information for the third-party identification analysis system.

Wherein the first resource information includes:

(4) the identification types supported by each third-party identification analysis system;

(5) the preset interaction rules supported by each third-party identification analysis system;

(6) and the mapping relation list of the address information and the object identification is obtained after the mapping relation list is analyzed by each third-party identification analysis system. The three resource information are specifically as follows:

(a) the identification types supported by the third-party identification resolution system are as follows: the method is used for representing the identification systems supported by each third-party identification analysis system, such as different identification systems of epc, handle, oid, ucode, mcode, and ecode.

Specifically, different third-party identifier parsing systems correspond to different identifier types, for example, a handle system corresponds to a handle identifier type, and the object identifier with the identifier type of handle may be parsed.

(b) The preset interaction rule supported by the third party identification analysis system comprises at least one of the following items: the identification of the corresponding interface of each third party identification analysis system, the communication protocol supported by each third party identification analysis system and the address identification of each third party identification analysis system.

The identifier of the interface corresponding to the third-party identifier resolution system, such as a flag parameter, is used for identifying the interface unit corresponding to each third-party identifier resolution system in the interaction module through the flag parameter. For example, the flag definition integer field '01' corresponds to the ONS interface element and '02' corresponds to the Handle system interface element. Optionally, an address identification of the interface unit may be provided.

The communication protocols supported by the third-party identifier resolution system, such as protocol parameters, are used for characterizing the communication protocols supported by or supported by each third-party identifier resolution system, for example, HTTP, CoAP, and the like.

The parameter is used to characterize the address id of the third party id resolution system, such as severAddr.

In addition, for example, a validaxexpression parameter, by which it is verified whether the object id meets the specification format requirement.

(c) And the mapping relation list of the address information and the object identification is obtained after the mapping relation list is analyzed by each third-party identification analysis system.

Specifically, for the object identifier which has been subjected to identifier analysis by the third-party identifier analysis system, a mapping relationship is established between the object identifier and the address information obtained after identification, and the object identifier is stored to generate the mapping relationship list, so that the object identifier can be directly obtained from the mapping relationship list when the same object identifier is subsequently queried, and the analysis operation by the third-party analysis system is not required.

Further, the interworking entity needs to ensure the accuracy of the mapping relationship list and perform timely maintenance. In one possible design, the manner of updating and maintaining the mapping relationship list according to the present invention may include, but is not limited to, the following two ways:

1. the interworking entity sends a mapping relation type verification request to the third party identification analysis system according to a preset time period, and updates the mapping relation list according to the received verification result fed back by the third party identification analysis system;

2. and the interworking entity receives the change message of the address information sent by the third-party identification analysis system and updates the mapping relation list according to the change message. For example, the update may be maintained by subscribing to a notification, specifically, subscribing to information of a specific object identifier in the third party identifier resolution system, and when the address information storing information corresponding to the object identifier changes, the third party identifier resolution system sends a change message to the interworking entity.

Further, when the interworking entity registers on the public service entity, by sending a resource creation request to the public service entity, after receiving the resource creation request, the advertisement service entity creates second resource information for the interworking entity in response to the resource creation request, where the second resource information includes a resource for storing information of each third-party identifier resolution system and an identifier type supported by each third-party identifier resolution system.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating a structure of creating resources of the interworking entity in the common service entity according to the present invention. As shown in fig. 3, the interworking entity registers with the common service entity, and creates the second resource information in the common service entity through a creation operation. Specifically, the second resource information includes a resource for storing information of each third-party identifier resolution system and an identifier type supported by each third-party identifier resolution system.

The registration operation of the third-party identification analysis system is completed, and the subsequent interactive identification discovery process with the interworking entity can be realized after the registration of the third-party identification analysis system is completed.

Further, after receiving the identifier discovery request, the interworking entity interworks with a third-party identifier resolution system through the interaction module to resolve the object identifier.

In the embodiment of the present invention, after receiving the identifier discovery request sent by the public service entity, the interworking entity queries whether address information corresponding to the object identifier is stored in a resource therein. According to different parameter settings in the identifier discovery request, the method for querying the interworking entity is correspondingly different, and the specific querying method is as follows:

when the parameter setting in the identifier discovery request adopts a scheme one in the identifier query entity, after the interworking entity receives the identifier discovery request sent by the public service entity, querying whether an instance resource in the interworking entity contains address information corresponding to the object identifier, wherein the directory instance resource is the first resource information created by the interworking entity according to the address information acquired by history.

Further, if the instance resource does not contain the address information corresponding to the object identifier, the interworking entity calls the preset interaction rule to send an identifier resolution request containing the object identifier to an identifier resolution server corresponding to the third-party identifier resolution system through the interaction module according to the identifier type of the object identifier;

and after receiving the analysis result correspondingly fed back by the identification analysis server, the interworking entity creates a new instance resource under the resource of a corresponding third-party external analysis system so as to store the mapping relation between the object identification and the address information in the analysis result.

When the parameter setting in the identifier discovery request adopts a scheme two in the identifier query entity, after the interworking entity receives the identifier discovery request sent by the public service entity, the interworking entity queries whether a mapping relation table in the interworking entity contains address information corresponding to the object identifier.

Further, if the mapping relation table does not contain address information corresponding to the object identifier, the interworking entity calls the preset interaction rule to send an identifier resolution request containing the object identifier to an identifier resolution server corresponding to the third-party identifier resolution system through the interaction module according to the identifier type of the object identifier;

and the interworking entity receives the analysis result correspondingly fed back by the identification analysis server and then feeds back the analysis result to the public service entity.

For example, if the identifier type of the object identifier is handle, the interaction module invokes an interaction unit corresponding to the identifier type of handle defined in the flag parameter in the first resource information and invokes a communication protocol supported by a third-party identifier resolution system supporting the identifier type of handle defined in the protocol parameter to communicate with the third-party identifier resolution system.

Specifically, the interaction module sends an identifier analysis request including an object identifier to a server corresponding to a handle system through a communication protocol supported by the handle system, the server analyzes the object identifier after receiving the identifier analysis request and feeds back an analysis result, and the analysis result includes address information used for storing information corresponding to the object identifier.

The embodiment is combined to show that the invention has the following maximum beneficial effects:

the invention discloses a method and a device for intercommunication between an M2M system and an identification analysis system, wherein the method sends an identification discovery request to a public service entity through an identification query entity; when the public service entity determines that the resources do not contain the information corresponding to the identifier discovery request, the intercommunication entity acquires the address information which is analyzed by the external analysis system and stores the information corresponding to the identifier discovery request, and the public service entity receives the address information, acquires the information corresponding to the object identifier stored in the address information and feeds the information back to the identifier query entity.
