Description

Technical Field



[0001] The present document relates to a machine-to-machine/man (M2M) communication technology, and particularly to a method and device for monitoring and controlling an M2M terminal device based on a policy.

Background of the Related Art



[0002] M2M communication system can be divided into three layers based on a logic function, including: a perceptual extension layer, a network/service layer and an application layer.

[0003] The perceptual extension layer: The perceptual extension layer mainly realizes collection, automatic identification and intelligent control of physical world information, and a main component included in it is an M2M terminal device. There are two types of M2M terminal device, one type is M2M terminal capable of communicating with M2M communication network, and the other is M2M gateway capable of communicating with the M2M communication network and M2M stub network.

[0004] The network/service layer: The network/service layer supports the transmission, routing and control of information of the perceptual extension layer, and supports the Internet of Things man-to-thing, thing-to-thing communication. The network layer specifically includes the following network forms based on classification of the Internet of Things: a communication network, an internet, an industry network, etc.; and a main component included in the network layer is an M2M platform.

[0005] The application layer: The application layer includes various specific applications of the Internet of Things: both public services and industry services. The industry services can be industry public services towards the public, also can be industry dedicated service for satisfying industry internal specific application requirements. A main component included in the application layer is an M2M application server, simply called M2M application.

[0006] However, in the related technology, the monitoring and control to the M2M terminal device by the M2M platform, i.e., the collection and related processing of various state parameters of the terminal device, can only be realized through platform active inquiring or terminal device active reporting according to platform defined period; the way of which is simple. However, the M2M terminal device is usually unattended, so requirements of the real-time, flexibility, etc., are requested on the monitoring and control method of the M2M terminal device.

[0007] The document US 2014/0189075 discloses exemplary M2M device client systems, methods, and interfaces.

[0008] The document "Towards a Framework for Dynamic Verification of Peer-to-Peer Systems", Theofrastos Koulouris et al, XP031096848, discloses that ensuring dependability and security of peer-to-peer systems is an intricate task due to the autonomous and volatile nature of peers and the decentralization that characterizes such systems. CN103702344 discloses dividing M2M devices into M2M groups based on predetermined parameters, generating control instructions per M2M group and send the instructions to the corresponding M2M groups.

Content of the Invention



[0009] The present invention defines a method according to claim 1 and a M2M platform according to claim 6. Further improvements and embodiments are provided in the dependent claims 2-5 and 7-9.

[0010] The present document provides a method and apparatus for monitoring and controlling an M2M terminal device based on a policy. An M2M platform obtains a state monitoring and control policy, stores a state control policy of the state monitoring and control policy, issues a state monitoring policy of the state monitoring and control policy, receives reported state information, and triggers a state control operation according to the state information and the state control policy. An M2M terminal device receives the state monitoring policy, triggers a state monitoring operation according to the state monitoring policy, reports monitored state information, receives operation information, and executes the state control operation according to the operation information. Thus, the monitoring and control of the M2M terminal device is in real-time and flexible, and the management efficiency of the M2M system to the M2M terminal device is improved.

Embodiment 1:



[0055] This embodiment realizes a method for monitoring and controlling an M2M terminal device based on a policy, as shown in FIG. 7, the method includes the following step.

[0056] In step 701: an M2M application generates a state monitoring and control policy according to the state monitoring and control requirements of the M2M terminal device, and sends it to the M2M platform through a policy issue message; the policy issue message includes an identifier of the M2M terminal device and the state monitoring and control policy.

[0057] It should be illustrated that, the state monitoring and control policy includes: a state monitoring policy and a state control policy.

[0058] The condition value can be a time value of a system clock or a timer corresponding to the M2M terminal device, which is a designated moment or frequency, and an example is as follows:
Condition valueState parameter identifier
time value #1 state parameter a, state parameter b
time value #2 state parameter c
... ...


[0059] Or, the condition value can be a state value of one or multiple operation states corresponding to the M2M terminal device, such as a parameter of work temperature, system load, etc., and an example is as follows:

[0062] In step 703: after receiving the policy issue message sent by theM2M platform, the M2M terminal device reads the state monitoring policy included in the policy issue message, and stores in local configuration information.

[0063] In step 704: the M2M terminal device, when detecting that the time value of the system clock or the timer reaches a time value defined in the state monitoring policy, or the operation state satisfies a state value defined in the state monitoring policy, collects the state parameter of the M2M terminal device corresponding to the time value or state value defined in the state monitoring policy, and sends the collected state parameter to the M2M platform through a state report message.

[0064] In step 705: the M2M platform receives the state report message sent by the M2M terminal device, reads the state parameter included in the state report message, and judges whether to trigger the corresponding state control operation process according to the trigger threshold defined in the state control policy:
  1. 1) if the state parameter reported by the M2M terminal device does not reach the trigger threshold, then the M2M platform records the state parameter reported by the M2M terminal device, and the current state monitoring and control process ends;
  2. 2) if the state parameter reported by the M2M terminal device reaches the trigger threshold, then the M2M platform sends operation information of the state control operation type corresponding to the trigger threshold to the M2M terminal device through an operation issue message.


[0065] In step 706: the M2M terminal device receives the operation issue message sent by the M2M platform, reads the operation information included in the operation issue message, executes the corresponding operation, such as reducing power, decreasing load, etc., and feeds back an operation executive result to the M2M platform.

[0066] The operation executive result includes: an operation executive success indicator and a state value of the M2M terminal device after executing the operation successfully, or an operation failure indicator and a reason value of the failure.

[0067] The operation executive result can include the following two conditions:
  1. 1) success indicator + state value;
  2. 2) failure indicator + reason value.


[0068] In step 707: the M2M platform receives the operation executive result reported by the M2M terminal device, and records the current operation executive result.

[0071] It should be illustrated that, the state monitoring and control policy includes: a state monitoring policy and a state control policy. The state monitoring policy includes: an event definition of the M2M terminal device executing event detection and reporting, and an event type identifier corresponding to the event definition; and the state control policy includes a judgment logic of triggering the state control operation by the M2M platform based on the event type reported by the M2M terminal device.

[0072] The event definition can be pre-defined activity of the M2M terminal device, such as system restart, fault alarm, etc., and an example is as follows:
Event definitionEvent type identifier
event definition #1 event type A
event definition #2 event type B
... ...


[0073] The judgment logic refers to that: event type identifier reported by the M2M terminal device is corresponding to the operation information triggered by the M2M platform, such as initialization scheme issue, configuration parameter issue, etc., and an example is as follows:
