Description

Data reporting method and device

Technical Field

The present application relates to the field of communications, and in particular, to a data reporting method and apparatus.

Background

With the advance of smart cities, some traditional industries are also gradually evolving towards intellectualization, such as water affairs, electric power, gas and other industries, and they are all accessing metering table devices, Data Transfer Units (DTUs) and the like to a cloud-side internet of things platform. At present, most of devices such as each meter class device and the DTU are accessed to the network by using a General Packet Radio Service (GPRS) access technology, but in consideration of network quit of a 2G network, each industry vertical tries to promote that a narrowband Internet of Things (NB-IoT) access technology is used to access the devices to the network.

However, some old devices or underlying sensing devices do not support NB-IoT access technology because they do not have the capability of long-distance transmission. For these devices, data exchange with the internet of things IoT platform through NB-IoT capable devices is required. For example, in a smart gas solution, the DTU needs to be modified to support NB-IoT communication capabilities, the networking and protocol stacks of which are shown in fig. 1 and 2. The DTU integrated NB-IoT module at the client has the communication capability with the Internet of things platform at the server; the flow meter adopts MODBUS remote terminal unit (MODBUS RTU) agreement and DTU communication, and the thing networking platform is forwarded to through the DTU to the data. LwM2M is a lightweight Machine to Machine (lightweight Machine to Machine) Protocol, CoAP is a Constrained Application Protocol (Constrained Application Protocol), UDP is a User Datagram Protocol (User Datagram Protocol), IP is an Internet Protocol (Internet Protocol), TCP is a Transmission Control Protocol (Transmission Control Protocol), and HTTP is a HyperText Transfer Protocol (HyperText Transfer Protocol). And the request message issued by the platform of the Internet of things is forwarded to the flow meter through the DTU. The protocol process is roughly as follows:

(1) the DTU is accessed to the Internet of things platform through an LwM2M protocol;

(2) the DTU and the Internet of things platform transmit data reported by a flow meter or transmit a request message issued by the Internet of things platform through an Appdata object specified in an LwM2M protocol, and the data format in the Appdata is an MODBUS RTU protocol.

(3) And the communication protocol between the flow meter and the DTU is unchanged, and the data reported by the flow meter is still transmitted by adopting an MODBUS RTU protocol.

However, since the MODBUS RTU protocol is in Client/server (C/S) mode, the flow meter needs to receive a request message before it can return a response message. Therefore, before the data is reported by the flow meter, the internet of things platform is required to issue a request message to the DTU, and then the request message is forwarded to the flow meter through the DTU, so as to obtain the data of the flow meter. Therefore, more message interaction between the Internet of things platform and the DTU is caused, and the power consumption of the DTU end is increased.

Detailed Description

The embodiment of the application is mainly applied to an NB-IoT network architecture, as shown in FIG. 3. The terminal device is a non-LwM2M (non-LwM2M) device, and the non-LwM2M device does not support NB-IoT access technology and cannot directly communicate with the LwM2M server. The terminal device is used for receiving a message sent by the LwM2M server and forwarded by the LwM2M client, and reporting data to the LwM2M client. The LwM2M server is used for issuing commands, receiving execution results reported by the LwM2M client and remotely managing the terminal equipment. The LwM2M client communicates with the LwM2M server and is responsible for executing the command of the LwM2M server and reporting the execution result. The LwM2M client communicates with the terminal device, forwards a message sent by the LwM2M server to the terminal device, and receives data reported by the terminal device. Only one terminal device is shown in fig. 3, and there may be a plurality of terminal devices in practical applications. An LwM2M server refers to a server supporting the LwM2M protocol, and an LwM2M client refers to a client supporting the LwM2M protocol.

In the embodiment of the application, the LwM2M server periodically requests the terminal device for data according to the periodic information by indicating the LwM2M client to obtain the data of the terminal device, so that the purpose of periodically requesting the data of the terminal device is achieved, NB-IoT network resources are saved, and the power consumption of the device is reduced. The following examples are given by way of illustration.

For convenience of description, the LwM2M server is simply referred to as a server, and the LwM2M client is simply referred to as a client.

According to the network architecture shown in fig. 3, an embodiment of the present application provides a data reporting method 400, as shown in fig. 4. In this embodiment, mainly by extending the resource of the AppData Object in the LwM2M protocol, the data request issued by the server is periodically sent to the terminal device, and the terminal device is triggered to periodically report data to the server.

S401, the server sends period information to the client, and the period information is used for indicating the client to request data from the terminal equipment regularly according to the period information.

The server sends the cycle information through a monitor message, which is a Write operation or a Write-Composite operation in the LwM2M protocol. The monitoring message also carries a data request indication, and the data request indication and the period information are used for indicating the client to request data from the terminal device periodically.

Before S401, the terminal device and the client are already registered in the server, so the server can communicate with the client to collect data of the terminal device. After the terminal device registers with the server, the server obtains information such as the identifier of the terminal device, the protocol used by the terminal device, the data format of the terminal device and the like. The client registers to the server through a Register message in an LwM2M protocol, wherein the Register message can carry parameters 19/0 and/or 19/1, and 19/0 and/or 19/1 are examples of AppData objects.

The period information and data requests in the supervision message are indicated as instances of the AppData object. The resource definitions in the Appdata object are shown in Table 1.

TABLE 1

Wherein, the period resource is a newly added resource, and an example of the period resource is used for transmitting the period information. One instance of a Data resource is used to transmit a Data request indication. The server may send the data request indication and the period information to the client through a Write operation or a Write-Composite operation, and the data request indication and the period information may be sent in the same operation or in different operations. Taking the Write operation as an example, sending the data request indication and the period information to the client may be specifically Write (/19/0/0/0,/19/0/6/0), or may be Write (/19/0/0/0), Write (/ 19/0/6/0). Wherein the server sends the data request indication and the period information to the client through/19/0 instance. Taking the Write-Composite operation as an example, the sending of the data request indication and the period information to the client may be specifically the Write-Composite (/19/0/0/0,/19/0/6/0), or may be the Write-Composite (/19/0/0/0), the Write-Composite (/ 19/0/6/0).

S402, the server subscribes to the resource of the AppData object instance.

Specifically, the server subscribes to the resource of the AppData object through the object operation, which may be specifically object (/ 19/1). When the resource of the Appdata object changes, the client reports to the server through a Notify message, which may be Notify (/ 19/1). Wherein, the client forwards the data sent by the terminal device to the server through/19/1 instance.

S403, the client requests the terminal device for data periodically according to the period information.

S404, the client receives the data from the terminal equipment.

The client detects whether the period is reached, and sends a data request message to the terminal equipment each time the period is reached. And the client converts the protocol type of the data request indication from LwM2M protocol to non-LwM2M protocol recognizable by the terminal equipment to obtain a data request message. And after receiving the data request message each time, the terminal equipment reports data to the client.

The validity duration life time resource can be newly added to the data object, and as shown in table 1, one instance of the life time resource is used to transmit the validity duration. The valid duration is used for indicating the client to send a data request message to the terminal device periodically according to the period information within the duration represented by the life time. The server sends the valid duration to the client through a Write operation or a Write-Composite operation. Taking the Write operation as an example, the sending of the effective duration to the client may be specifically Write (/ 19/0/7/0).

Because the data request message is sent regularly, multiple times of data request message sending and corresponding times of terminal device data reporting exist between the client and the terminal device. This process is illustrated in FIG. 4 as S403A, S404A and S403B, S404B. It should be noted that only two interactions between the client and the terminal device are shown in fig. 4, and in practical cases, there may be more interactions.

S405, the client sends the data reported by the terminal equipment to the server.

And the client sends the data reported by the terminal equipment to the server every time the client receives the data reported by the terminal equipment. Because the server subscribes to the resource of the Appdata object, the client reports the data to the server through the Notify message every time the client receives the data reported by the terminal equipment. Such as S405A, S405B.

When the valid time resource is newly added in the Appdata object, when the time indicated by the valid time resource arrives, the client deletes the period information, and can also delete the data request indication and the valid time, and inform the server that the resources are deleted.

The sequence of the S401 and the S402 can be exchanged.

According to the technical scheme provided by the embodiment, the server sends the period information to the client, and instructs the client to send the data request message to the terminal equipment periodically according to the period information so as to request data, so that the message interaction between the client and the server is reduced, the bandwidth and the equipment energy consumption are further saved, and the network resource utilization rate is improved.

According to the network architecture shown in fig. 3, an embodiment of the present application provides a data reporting method 500, as shown in fig. 5. In this embodiment, mainly by introducing a mechanism of a trigger message into an LwM2M protocol, a data request issued by a server is periodically sent to a terminal device, and the terminal device is triggered to periodically report data to the server.

S501, the server sends a data request instruction to the client.

The server sends the data request indication via a monitor message, which is a Write operation or a Write-Composite operation in the LwM2M protocol. Before S501, the terminal device and the client have already registered with the server. The information related to registration is described in the foregoing S401, and is not described herein again.

The data request in the monitor message is indicated as an instance of an AppData object. The resource definitions in the Appdata object are shown in Table 2.

TABLE 2

Where one instance of a Data resource is used to transmit a Data request indication. The server sends the data request indication to the client via a Write operation or a Write-Composite operation. Taking the Write operation as an example, sending the data request indication to the client may specifically be Write (/ 19/0/0/0). The server sends a data request indication to the client via the/19/0 instance.

S502, the server subscribes to the resource of the Appdata object instance.

Specifically, the server subscribes to the resource of the AppData object through the object operation, which may be specifically object (/ 19/1). When the resource of the Appdata object changes, the client reports to the server through a Notify message, which may be Notify (/ 19/1). The client forwards the data sent by the terminal device to the server through the/19/1 instance.

S503, the server sends period information to the client, and the period information is used for indicating the client to request data from the terminal device regularly according to the period information.

The periodic information is sent through a trigger message, which is an extended message in the LwM2M protocol. The trigger message also carries a trigger object, and the trigger object is the data request indication and indicates that the client needs to be triggered to periodically send a data request to the terminal device. The Trigger message may be implemented by adding a Trigger interface, which may specifically be Trigger (/19/0/0/0, period), where period is period information, and/19/0/0/0 is a Trigger object, that is, a data request indication.

And S504, the client requests the terminal equipment for data regularly according to the period information.

And S505, the client receives the data from the terminal equipment.

Because the data request message is sent regularly, multiple times of data request message sending and corresponding times of terminal device data reporting exist between the client and the terminal device. This process is illustrated in fig. 5 by S504A, S505A and S504B, S505B. It should be noted that only two interactions between the client and the terminal device are shown in fig. 5, and in practical cases, there may be more interactions.

S506, the client sends the data reported by the terminal equipment to the server.

And the client sends the data reported by the terminal equipment to the server every time the client receives the data reported by the terminal equipment. Because the server subscribes to the resource of the Appdata object instance, the client reports the data to the server through the Notify message every time the client receives the data reported by the terminal device. Such as S506A and S506B.

The server can also send a cancellation trigger message to the client, wherein the cancellation trigger message is used for indicating the client to stop requesting data from the terminal equipment regularly. Specifically, GET/19/0/0/0Trigger 1, where "1" indicates to cancel the Trigger. And after receiving the cancel trigger message, the client stops sending the data request message to the terminal equipment regularly.

The sequence of the above S501 and S502 can be exchanged.

According to the network architecture shown in fig. 3, an embodiment of the present application provides a data reporting method 600, as shown in fig. 6. In this embodiment, mainly by extending the resource of the AppData Object in the LwM2M protocol and adding an Object (Object) in the LwM2M protocol, the data request sent by the server is periodically sent to the terminal device, and the terminal device is triggered to periodically report data to the server.

S601, the server sends the periodic information link to the client.

S602, the server sends period information to the client, the period information is linked and points to the period information, and the period information is used for indicating the client to request data from the terminal device regularly according to the period information.

The periodic information link is sent through a first monitoring message, and the periodic information link is sent through a second monitoring message. The first monitor message and the second monitor message are a Write operation or a Write-Composite operation in the LwM2M protocol. The first monitoring message may further carry a data request indication, where the data request indication and the period information are used to indicate that the client regularly requests data from the terminal device.

Before S601, the terminal device and the client have already registered with the server. The information related to registration is described in the foregoing S401, and is not described herein again.

The period information in the first supervisory message is linked to an instance of the AppData object. The resource definitions in the Appdata object are shown in Table 3.

TABLE 3

Wherein, the period resource is a newly added resource, and an instance of the period resource is used for transmitting the periodic information link. One instance of a Data resource is used to transmit a Data request indication. The server sends the data request indication and the period information link to the client through the Write operation or the Write-Composite operation, and the data request indication and the period information link can be sent in the same operation or different operations. Taking the Write operation as an example, the link between the sending data request indication and the period information to the client may be specifically Write (/19/0/0/0,/19/0/6/0), or Write (/19/0/0/0), Write (/ 19/0/6/0). Wherein the server sends the data request indication and the periodic information link to the client via the/19/0 instance.

The period information in the second monitoring message is an example of an added object, the identifier of the added object may be 22 (or may be an identifier other than the object identifier already existing in the LwM2M protocol), and the added object includes the resources shown in table 4.

TABLE 4

Wherein one instance of the period resource is used to transmit the period information. The server transmits the period information to the client through a Write operation or a Write-Composite operation. Taking the Write operation as an example, sending the period information to the client may specifically be Write (/ 22/0/0/0). The server sends the period information to the client via the/22/0 instance.

S603, the server subscribes to the resource of the Appdata object instance.

S604, the client requests the terminal device for data periodically according to the period information.

S605, the client receives data from the terminal device.

A new valid time link resource may be added to the appldata object, and as shown in table 3, one instance of the valid time link resource is used for transmitting the valid time link. The validity duration link is sent via the first monitoring message. The server sends the valid long chain to the client via a Write operation, which may be specifically Write (/19/0/7/0), or a Write-Composite operation. The newly added object may further include an effective duration life time resource, and an example of the effective duration resource is used for transmitting the effective duration. The effective duration is sent through the second monitoring message. The server sends the valid duration to the client via a Write operation, such as Write (22/0/1/0), or a Write-Composite operation. The validity duration link in the Appdata object instance points to the validity duration in the newly added object instance. The valid duration is used for indicating the client to send a data request message to the terminal device periodically according to the period information in the duration represented by the valid duration.

Because the data request message is sent regularly, multiple times of data request message sending and corresponding times of terminal device data reporting exist between the client and the terminal device. This process is illustrated in fig. 6 by S604A, S605A and S604B, S605B. It should be noted that only two interactions between the client and the terminal device are shown in fig. 6, but in practical cases, there may be more interactions.

And S606, the client sends the data reported by the terminal equipment to the server.

And the client sends the data reported by the terminal equipment to the server every time the client receives the data reported by the terminal equipment. Because the server subscribes to the resource of the Appdata object, the client reports the data to the server through the Notify message every time the client receives the data reported by the terminal equipment. Such as S606A, S606B.

And adding an effective duration link resource in the Appdata object, deleting the period information by the client when the duration indicated by the effective duration reaches when the effective duration resource is added in the added object, deleting the data request indication and the effective duration, and informing the server that the resources are deleted.

The sequence of the above S601, S602, S603 can be exchanged.
