Description

Method of interaction between devices and machine communication network system

Technical field

Embodiments of the present invention relate to machine communication technologies, and in particular, to an interaction method between devices and a machine to machine (M2M) network system. Background technique

With the improvement of communication services between people and the continuous development of intelligent electronic technology, the equipment as a peripheral facility already has the ability to participate in communication; and, intelligent integration represented by security, intelligent warehousing and logistics The demand for information processing is gradually increasing, and an M2M network system for realizing communication between machines and devices has appeared.

The European Telecommunications Standards Institute (ETSI) established the M2M Technical Committee (ETSI TC M2M), which proposes a level of M2M network architecture for multiple applications. The M2M network system includes a plurality of devices, a network middleware, and an application server. Multiple devices interact with the application server through the network middleware, that is, the device only interacts with the network middleware, the network middleware interacts with the device and the application server, and the application server only interacts with the network middleware.

In an actual M2M application, there is a large demand for interaction between devices and devices, and one device needs to acquire the state or information of another device. For example: In smart home applications, when the sensor detects that the humidity in the home is below a certain threshold, it needs to turn on the humidifier at home, and when the humidity rises to a certain value, it needs to trigger the humidifier to turn off; in the item monitoring application, when When the sensor detects that the item is moved, it needs to open or rotate the nearby camera. In the smart security application, when the camera at the door of the resident or the warehouse in the factory monitors someone entering, it needs to trigger the alarm of the community guard room or the warehouse monitoring room. The device sounds an alarm. When the device interacts with the device using the existing M2M network system, the following four interaction processes are required: First, the application server subscribes to the network device for the first device information; second, the first device sends Information to network middleware, network The middleware notifies the application server of the received information of the first device; the third time, the second device subscribes the application server information to the network middleware; the fourth time, the application server processes the received information of the first device and sends the information. To the network middleware, the network middleware notifies the second device. The above interaction method must go through four interaction processes, not only because the message between the two devices, the network middleware, and the application server occupies a large amount of network resources, resulting in a long network delay, resulting in low network processing efficiency; Moreover, since the message of the first device must first be sent to the application server through the network middleware, and then the second server action is triggered by the application server through the network middleware, when the link between the application server and the network middleware is disconnected, The second device cannot trigger an action according to the message of the first device. In summary, with the existing M2M network system and its interaction method, the correct rate of interaction between devices is low, and the network processing efficiency is low. Summary of the invention

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

FIG. 1 is a flowchart of a method for interaction between devices according to Embodiment 1 of the present invention. This method is applied

M2M network system to realize the interaction between various devices in the M2M network system. The M2M network system includes: an application server, a network middleware, a first device, and a second device. In the first embodiment of the present invention, interactive control by the network middleware is taken as an example. As shown in Figure 1, the method includes the following process.

Step 101: The network middleware acquires an interaction policy generated by the application server.

In this step, the interaction strategy includes: a trigger event and a message processing method. Step 102: The network middleware controls the first device to monitor the trigger event, and controls the first device to send a trigger event occurrence notification message to the network middleware when the trigger event occurs.

Step 103: The network middleware processes the trigger event occurrence notification message according to the message processing method, generates a notification message, and sends the notification message to the second device, so that the second device performs the corresponding operation according to the notification message.

In the first embodiment of the present invention, the application server generates or obtains an interaction policy indicating a trigger event, and the network middleware controls the first device to monitor the trigger event. When the trigger event occurs, the network middleware generates a notification message according to the monitoring result. Sending to the second device, the second device can perform the corresponding operation according to the trigger event generated by the first device by using an interaction process, thereby avoiding having to perform the interaction process for the second device through four interaction processes as in the existing interaction method. Triggering saves network resources and reduces network latency by reducing message interaction, thereby improving network processing efficiency.

FIG. 2 is a signaling flowchart of a method for interaction between devices according to Embodiment 2 of the present invention. The method is applied to an M2M network system, where the M2M network system comprises: an application server, a network middleware, a first device, and a second device. In the second embodiment of the present invention, interactive control is performed by a network middleware as an example. As shown in FIG. 2, the method includes the following process.

Step 201: The network middleware acquires an interaction policy from the application server.

In this step, first, the application server acquires an interaction policy, and then the network middleware acquires an interaction policy from the application server. The network middleware can obtain the interaction policy from the application server in any of the following ways: Method 1: The application server sends the interaction policy to the network middleware. In the second mode, the network middleware actively obtains the interaction policy from the application server. The application server can obtain the interaction policy according to multiple ways. For example, the application server can generate the interaction policy according to the service relationship between the first device and the second device, or the application server can also provide a service operation support system (Business Operation Support System, Referred to as BOSS) request to obtain the interaction strategy.

The interaction strategy includes: a trigger event and a message processing method. The triggering event is an event that occurs on the first device that triggers the operation of the second device. For example, the first device is a sensor network, and the sensor network includes a humidity sensor for detecting humidity and a sensor for processing a message. The gateway, the second device is a humidifier, and the functions required by the M2M network system are: When the humidity sensor in the sensor network detects that the humidity is lower than the threshold, the trigger event is: The sensor network detects that the humidity is lower than the threshold. . The message processing method is used to instruct the network middleware to process the message to generate a notification message after receiving the trigger event occurrence notification message of the first device.

Step 202: The network middleware stores an interaction strategy.

Step 203: The network middleware returns an interaction policy receiving response message to the application server.

Step 204: The network middleware sends a subscription request message to the first device.

In this step, the network middleware sends a subscription request message to the first device according to the received interaction policy. The subscription request message includes a trigger event indicated in the interaction policy. The functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is lower than the threshold, the humidifier is turned on, and the network middleware sends a subscription request message to the sensor network, and the request message indicates that the trigger event is that the monitoring humidity is lower than the Threshold.

Step 205: The first device records a subscription request message.

Step 206: The first device returns a subscription request response message to the network middleware.

Step 207: The first device monitors the trigger event.

In this step, the first device monitors the triggering event based on the subscription request message from the network middleware. The functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is lower than the threshold, the humidifier is turned on, and the sensor network starts to monitor whether the humidity is lower than the threshold according to the subscription request message.

Step 208: When the triggering event occurs, the first device sends a trigger event occurrence notification message to the network middleware.

In this step, when the triggering event occurs, the first device sends a trigger event occurrence notification message to the network middleware according to the subscription request from the network middleware. The functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is lower than the threshold, the humidifier is turned on. When the sensor network monitors that the humidity is lower than the threshold, the trigger event occurs, and the sensor network sends the network to the middleware. A trigger event notification message is triggered, indicating that the humidity is below the threshold. Step 209: The network middleware returns a receiving success response message to the first device.

Step 210: The network middleware generates a notification message according to the trigger event occurrence notification message.

In this step, the network middleware processes the trigger event occurrence notification message from the first device according to the message processing method in the acquired interaction policy, and generates a notification message. Specifically, the corresponding relationship between the trigger event and the content of the notification message is indicated in the message processing method. The network middleware learns the trigger event according to the trigger event occurrence notification message from the first device, and according to the instruction of the message processing method, learns the content of the notification message corresponding to the trigger event, thereby generating a corresponding notification message. The functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is below the threshold, the humidifier is turned on as an example. Then, the message processing method is: when a trigger event occurs in which the sensor network detects that the humidity is lower than the threshold, a notification message for turning on the humidifier is generated. After receiving the trigger event occurrence notification message from the sensor network, the network middleware processes the message according to the message processing method to generate a notification message, and the notification message indicates that the humidifier is turned on.

Step 211: The network middleware sends a notification message to the second device.

In this step, the functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is lower than the threshold, the humidifier is turned on as an example, and the network middleware sends a notification message to the humidifier, and the message indicates that the humidifier is turned on.

Step 212: The second device performs a corresponding operation according to the notification message.

In this step, the functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is lower than the threshold, the humidifier is turned on as an example, and the humidifier indicates that the humidification is started according to the notification message received from the network middleware. Therefore, the humidifier performs an opening operation.

Step 213: The second device returns a receiving success response message to the network middleware.

After the step 213, the second device is triggered to perform the corresponding operation according to the information acquired by the first device. When the second device no longer needs to trigger the operation according to the information acquired by the first device, the interaction policy may be cancelled. The specific process includes the following steps 214 to 218.

Step 214: The application server sends a cancel interaction policy request message to the network middleware.

In this step, the application server sends the cancellation interaction policy to the network middleware according to the cancellation instruction. Slightly request a message. Specifically, the application server may obtain the cancellation instruction according to multiple ways, for example, the application server may receive the cancellation instruction from the second device, or the application server may also receive the cancellation instruction from the BOSS. The cancel interaction policy request message includes: a trigger event in the interaction policy to be canceled.

Step 215: The network middleware sends an unsubscribe request message to the first device.

In this step, the network middleware first performs message processing on the received cancel interaction policy request message, and generates an unsubscribe request message according to the cancel interaction policy request message, where the unsubscribe request message includes a trigger event in the interaction policy to be canceled. The network middleware then sends a cancel subscription request message to the first device.

Step 216: The first device stops monitoring the trigger event in the interaction policy to be canceled.

In this step, the first device performs message processing on the received unsubscribe request message, and stops monitoring the trigger event in the interaction policy to be canceled according to the unsubscribe request message.

Step 217: The first device returns an unsubscribe response message to the network middleware.

Step 218: The network middleware returns a cancel interaction policy response message to the application server.

In this step, the network middleware first performs message processing on the received unsubscribe response message, generates a cancel interaction policy response message according to the unsubscribe response message, and then the network middleware sends the cancel interaction policy response message to the application server.

In the second embodiment of the present invention, the application server generates or obtains an interaction policy indicating a trigger event, and the network middleware controls the first device to monitor the trigger event according to the interaction policy. When the trigger event occurs, the first device notifies the network. The network middleware generates a notification message and sends it to the second device. The interaction policy is used to control, and the second device can learn that the first device has a trigger event through an interaction process, thereby reducing message interaction, saving network resources and shortening network delay, thereby improving network processing efficiency. The interaction between the first device and the second device does not need to be controlled by the application server. If the application server disconnects from the M2M network system after the interaction policy is sent to the network middleware, the second embodiment of the present invention is used. The interaction method, the second device can still correctly know that the trigger event occurs on the first device, and avoids the existing interaction method. The interruption of interaction between devices caused by the disconnection of the application server improves the correct rate of interaction between devices.

Step 302: The first device monitors a trigger event.

In this step, the first device monitors the trigger event according to the acquired interaction policy.

Step 303: When the triggering event occurs, the first device generates a notification message according to the message processing method and sends the notification message to the second device by using the network middleware, so that the second device performs the corresponding operation according to the notification message.

In the third embodiment of the present invention, the application server generates or obtains an interaction policy indicating a triggering event, and the first device acquires the interaction policy through the network middleware and monitors the trigger event according to the interaction policy. When the trigger event occurs, The first device generates a notification message according to the monitoring result and sends the notification message to the second device through the network middleware, and the second device can perform the corresponding operation according to the trigger event generated by the first device by using the interaction process, thereby avoiding the existing interaction method. In this way, the triggering of the second device must be implemented through four interaction processes, which reduces network resources and shortens the network delay by reducing message interaction, thereby improving network processing efficiency.

FIG. 4 is a signaling flowchart of a method for interaction between devices according to Embodiment 4 of the present invention.

The first device is a sensor network. In this step, the sensor network monitors whether the humidity is lower than the threshold.

Step 408: When the triggering event occurs, the first device sends a notification message to the network middleware. In this step, when the triggering event occurs, the first device first learns the content of the notification message corresponding to the triggering event according to the indication of the message processing method in the interaction policy, generates the notification message, and then sends the notification message to the network middleware. . The functions still required to be implemented by the M2M network system are as follows: When the sensor network detects that the humidity is lower than the threshold, the humidifier is turned on as an example. Then the message processing method is: When a trigger event occurs in which the sensor network detects that the humidity is below the threshold, a notification message to turn on the humidifier is generated. When the sensor network detects that the humidity is below the threshold, the sensor network generates a notification message according to the message processing method, the notification message indicates that the humidifier is turned on, and then the sensor network sends the notification message to the network middleware.

Step 409: The network middleware performs authority verification.

In this step, the network middleware performs the rights verification on the first network device according to the sending permission indication obtained in step 402, to verify whether the first device has the right to send a message to the second network device, and when the verification is passed, step 410 is performed. .

Step 410: The network middleware forwards the notification message to the second device.

Step 411: The second device performs a corresponding operation according to the notification message.

Step 412: The second device returns a receiving success response message to the network middleware.

Step 413: The network middleware returns a receiving success response message to the first device.

After the step 413, the second device is triggered to perform the corresponding operation according to the information acquired by the first device. When the second device no longer needs to trigger the operation according to the information acquired by the first device, the interaction policy may be cancelled. The specific process includes the following steps 414 to 418.

Step 414: The application server sends a cancel interaction policy request message to the network middleware.

In this step, the application server sends the cancel interaction policy request message to the network middleware according to the cancel instruction. The manner in which the application server obtains the cancellation instruction is the same as the step 214 in the second embodiment of the present invention, and details are not described herein again. The cancel interaction policy request message includes: a trigger event in the interaction policy to be canceled.

Step 415: The network middleware forwards the cancel interaction policy request message to the first device.

Step 416: The first device stops monitoring the trigger event in the interaction policy to be canceled.

Step 417: The first device returns a cancel interaction policy response message to the network middleware.

Step 418: The network middleware forwards the cancel interaction policy response message to the application server.

In the fourth embodiment of the present invention, the application server generates or obtains an interaction policy indicating a trigger event, and the first device monitors the trigger event according to the interaction policy. When the trigger event occurs, the first device generates a notification message and passes the network middleware. Forward to the second device. The interaction policy is used to control, and the second device can learn that the first device has a trigger event through an interaction process, thereby reducing message interaction, saving network resources and shortening network delay, thereby improving network processing efficiency. The interaction between the first device and the second device does not need to be forwarded by the application server. If the application server is disconnected from the M2M network system after the interaction policy is sent to the network middleware, the interaction method of the fourth embodiment of the present invention is adopted.
