Problems solved by technology

If the current IoT terminal needs to transmit a large amount of data, the 3G network may allocate a dedicated channel for the IoT terminal, so that the IoT terminal is in a high-service data transmission mode, which will lead to excessive power consumption of the IoT terminal; At the same time, the process of data interaction between IoT terminals is intermittent. If IoT terminals are always in high-service data transmission mode, it is easy to cause waste of communication resources.

Embodiment 1

[0058] An embodiment of the present invention provides a data transmission method for the Internet of Things, which is applied to an Internet of Things terminal, such as figure 1 As shown, the Internet of Things data transmission method includes:

[0059] Step 101, sending data to be sent.

[0060]For example, when the IoT terminal currently needs to send data to be sent, it can first divide the data to be sent into multiple data blocks for buffering, read one data block per second and send it, and at this time send the data transmission of the data to be sent The rate is the ratio of the data volume of the data block to the time 1 second. Wherein, the data volumes of the multiple data blocks are equal.

[0061] Step 102, determine whether the current communication state is CELL_DCH mode.

[0062] For example, the modes in which service data can be transmitted in the 3G network are defined as CELL_DCH (Cell Dedicated Channel, cell dedicated channel) mode and CELL_FACH (Cell...

Embodiment 2

[0079] An embodiment of the present invention provides a data transmission method for the Internet of Things, which is applied to an Internet of Things terminal, such as figure 2 As shown, the method includes:

[0080] Step 201, acquire the data rate threshold, and execute step 202.

[0081] For example, the Internet of Things terminal may obtain the default data rate threshold, or obtain the data rate threshold when it was shut down last time.

[0082] Step 202: Buffer the data to be sent according to the data rate threshold, and execute step 203.

[0083]For example, the data to be sent can be divided into multiple data blocks for storage, and the size of the data blocks can be adjusted according to the data rate threshold. For example, assuming that the data rate threshold is 100k / s, after obtaining the data to be sent that needs to be sent, the data to be sent can be divided into data blocks less than or equal to 100k for storage. Specifically, the division may be perf...

Embodiment 3

[0103] An embodiment of the present invention provides an IoT terminal 30, such as image 3 shown, including:

[0104] The sending unit 301 is configured to send data to be sent.

[0105] The first determining unit 302 is configured to determine whether the current communication state is the CELL_DCH mode.

[0106] The reducing unit 303 is configured to reduce the data transmission rate for sending the data to be sent if the current communication state is CELL_DCH mode, so that the communication state is switched from CELL_DCH mode to CELL_FACH mode.

[0107] In this way, when the communication status of the IoT terminal under the 3G network is CELL_DCH mode instead of CELL_FACH mode, the communication status of the IoT terminal can be switched from CELL_DCH mode to CELL_FACH mode by reducing the data transmission rate of the IoT terminal, and then The IoT terminal can always be in the CELL_FACH mode, realizing the low-speed and low-power data transmission of the IoT termina...

Abstract

The embodiment of the invention discloses an internet of things data transmission method. The method comprises the following steps: sending to-be-sent data; determining whether the current communication state is the cell dedicated channel CELL_DCH mode; reducing the data transmission rate for sending the to-be-sent data if the current communication state is the CELL_DCH mode, thereby enabling the communication state to switch to the cell forward access channel CELL_FACH mode from the CELL_DCH mode. Furthermore, the embodiment of the invention further discloses an internet of things terminal.

Description

technical field [0001] The present invention relates to the Internet of Things communication technology in the field of communication, and in particular to an Internet of Things data transmission method and an Internet of Things terminal. Background technique [0002] With the development of computer technology, Internet technology and mobile communication technology, the Internet of Things has also developed rapidly in various application fields. Identify, locate, track, monitor and manage networks. [0003] In the prior art, since the Internet of Things terminals need to upload less data to the Internet, the Internet of Things terminals only need to establish a low-speed transmission channel with the Internet. At the same time, because the Internet of Things terminals need to continuously send information to the Internet for a long time, therefore The requirements for the standby time of the Internet of Things terminal are relatively high, which requires the terminal to e...
