It can also include sub-group resources, which are created in advance by IoT applications or other applications. This creation request should include the requester’s ID, group member’s letter
Information, recipient identification. The device group management module receives the access request, obtains the parameters in the access request, confirms that the parameters are legal, and continues
Business processing. The platform group management module located on the IoT support platform creates group resources and maintains group resources and member information, and provides information to the IoT
The application returns the group ID.
e The device group management module returns the response result, which includes the status report (such as success, failure) and the identification of the new group.
f The Internet of Things application initiates a batch access request for group member resources. This access request should provide the requester ID, access type, group ID information, and receiving
Party logo. The platform group management module receives the access request, obtains the parameters in the access request, confirms that the parameters are legal, and continues to perform business processing
Rationale. The platform group management module obtains the information of each group member according to the group identification information provided by the IoT application, and accesses the group members in batches (such as
Batch acquisition of sensor data, control equipment, etc.).
g The platform group management module distributes multiple member resource access requests to IoT devices and gateways. Each member resource access request includes the requestor logo
The identification, access type, group member information, and recipient identification are processed and returned by the IoT device and gateway that receive the access request. Internet of things equipment, network
Obtain the parameters in the access request and confirm that the parameters in the access request are legal, and continue business processing.
h The device group management module returns the response result, which includes the status code (such as success, failure) and result data.
i The platform group management module can determine the group based on the group member information obtained from the group identification information after receiving the group member resource batch access request
In a series of member resources located in the same gateway or the same device, and thus create subgroups (see b, c). Device management module creates subgroup resources
And maintain sub-group resources and member information.
j The device group management module returns the response result, which includes a status report (such as success, failure) and subgroup identification.
k The platform group management module distributes batch access requests for subgroup members' resources to IoT devices and gateways (see f). The requesting party should be included in the access request
Identification, access type, subgroup identification, recipient identification. The IoT device and gateway obtain the parameters in the access request and confirm the parameters in the access request.
The number is legal, and business processing continues. The sub-group access request is decomposed by the device group management module of the IoT gateway and device that received the access request
Distribute member resources for multiple member resource access requests. Among them, the sub-group resources consist of a series of member resources located in the same gateway or the same device
The composition is determined and created by the application of the Internet of Things or the support platform of the Internet of Things. In addition, the group management module should also have the ability to identify repeated and circular memberships.
The capabilities of the source, such as group member information obtained from group identification information. And based on the group member information, it is determined that the subgroup resources are included
When the group management module receives the group member resource batch access request, it can also generate a request identifier, which will be issued to the member resource along with the member resource access request.
Stored, if the group management module of the entity where the member resource is located determines that subsequent member resource access requests with the same request identifier are received, it will ignore
Slightly receive the access request.
l The device group management module distributes member resource access requests to IoT devices and gateways (see g).
m IoT devices and gateways return response results, which include status codes (such as success, failure) and result data (see h).
n The device group management module aggregates the response and returns the response result. The response should include status reports (such as success, failure) and result data.
o The platform group management module gathers the response and returns the response result. The response should include status reports (such as success, failure) and result data.
