Problems solved by technology

[0006] It is found in the prior art that when an M2M node is deleted due to failure or other reasons, and then registers with its registered CSE again, the data stored on the registered CSE by the AE and CSE on the M2M node are lost, resulting in M2M Data loss after node failure is repaired

Embodiment 1

[0111] Such as figure 2 As shown, this embodiment provides a method for deleting an M2M node, and the method includes:

[0112] Receiving step S110: receiving a node deletion request of the first M2M node;

[0113] Responding step S120: responding to the node deletion request, deleting the node resource of the first M2M node, and retaining the entity resource corresponding to the first M2M node;

[0114] The entity resources include at least one of application entity AE resources and common service entity CSE resources.

[0115] In this embodiment, when the node is deleted, since the entity resource is retained, obviously the data in the entity resource can be preserved, and obviously there will be no problem of data loss stored in the entity resource.

[0116] After the responding step, the method also includes a timing step:

[0117] The timing steps include:

[0118] Start the timer to start timing the retention duration;

[0119] When a new node resource address is a...

Embodiment 2

[0125] Such as image 3 As shown, this embodiment provides a method for deleting an M2M node, and the method includes:

[0126] Step S101: receiving a node deletion request of the first M2M node;

[0127] Step S102: Responding to the node deletion request, delete the node resource of the first M2M node, and store data on the entity resource corresponding to the first M2M node;

[0128] The entity resources include at least one of application entity AE resources and common service entity CSE resources.

[0129] In the prior art, when an M2M node is deleted, the node resource and the entity resource of the M2M node will be deleted synchronously, resulting in the loss of data in the entity resource, and the loss of data in the entity resource; , the registered CSE does not change any data of the entity on the M2M, resulting in the loss of previous data.

[0130] Specifically, for example, there is a monitoring application running on the camera installed at A; the camera is the...

Embodiment 3

[0164] Such as Figure 6 As shown, this embodiment provides a method for deleting an M2M node, and the method includes:

[0165] Step S310: receiving a node deletion request of the first M2M node;

[0166] Step S320: delete the node resource of the first M2M node according to the deletion request, extract the specified data stored on the entity resource of the first M2M node, store the specified data in a specified storage location, and save the specified data Deleting the entity resource after being stored in the specified storage location;

[0167] The entity resources include at least one of application entity AE resources and common service entity CSE resources.

[0168] In the method described in this embodiment, before deleting the physical resource, first extract the specified data on the physical resource, specifically such as monitoring information such as the monitoring video of the M2M node, and store it in a specified location; specifically, such as backing up th...

Abstract

The invention discloses M2M node deletion and registration methods and an M2M node. The deletion method comprises a receiving step of receiving a node deletion request from a first M2M node; and a response step of responding to the node deletion request, deleting node resources of the first M2M node, and reserving entity resources corresponding to the first M2M node, wherein the entity resources comprise at least one of application entity (AE) resources and common service entity (CSE) resources.

Description

technical field [0001] The present invention relates to a communication technology of a Machine Type Communication (MTC: Machine Type Communication) terminal in the communication field, and in particular to an information processing method and an electronic device. Background technique [0002] figure 1 Shown is an M2M (Machine To Machine) communication system, and the system includes a bearer network and M2M nodes communicating through the bearer network. The M2M nodes include application nodes, intermediate nodes and basic nodes. The M2M nodes communicate with each other through a bearer network, and each of the M2M nodes includes at least one application entity (ApplicationEntity, AE) or one common service entity (CommonServiceEntity, CSE). [0003] The Application Entity AE is a logical unit for executing actual M2M applications, and the Common Service Entity CSE is a logical unit for managing and serving applications. The communication between M2M applications is thr...
