Problems solved by technology

[0003] Generally, terminal devices are powered by batteries. How to save the power of terminal devices communicating in the network is the key to the wide application of terminal devices. In the prior art, terminal devices will enter the Connected state to receive downlink data, so that the terminal device will continuously switch between the inactive state and the connected state, which makes the power consumption of the terminal device large, and the power consumption is large

Embodiment 1

[0120] A data transmission method, which is mainly used in a data transmission system based on uplink services. For example, the Internet of Things is referred to as a machine-to-machine (M2M) network for short, and the data transmission method in this embodiment includes an application device and The method performed by the terminal equipment of the communication device, wherein the application device and the communication device may be separate entities, such as an electric meter (application device) in the logistics network and a device that can communicate with the electric meter, and the application device and the communication device may also be Two modules included in the same entity. Generally, the application device will upload the application information such as status information such as the reading of the electric meter to the server in the network through the communication device.

[0121] After the terminal device is powered on and registered to the network side,...

Embodiment 2

[0136] A data transmission method, which is mainly used in a data transmission system based on uplink services. The terminal equipment in the data transmission system includes an application device and a communication device. The method in this embodiment is the network side method in the first embodiment above. The method executed by the device, the flow chart of the method is as follows figure 2 shown, including:

[0137] Step 201, when the terminal device is in a first inactive state, the network side device buffers the downlink data of the terminal device.

[0138] Step 202, when the terminal device enters the connection state with the network side device, the network side device receives the uplink data sent by the terminal device, and sends the downlink data buffered in step 202 to the terminal device.

[0139] The steps performed by the terminal device are as described in the first embodiment above, and will not be repeated here. In the first inactive state, the term...

Embodiment 3

[0150] A data transmission method, which is mainly used in a data transmission system based on uplink services. The method in this embodiment is a method performed by a terminal device including an application device and a communication device, wherein the application device and the communication device may be separated Entity, or two modules included in the same entity.

[0151] After the terminal device is powered on and registered to the network side, the terminal device can have two states, that is, the inactive state and the connected state. The method of the embodiment of the present invention is a data transmission method for the terminal device after it is powered on and registered to the network side. The flow chart is as follows Figure 4 shown, including:

[0152] Step 301, when the terminal device does not need to send uplink data, put the terminal device in a second inactive state. If the communication device in the terminal device does not receive the uplink dat...

Abstract

The invention relates to a method, a device and a system for data transmission, network equipment and terminal equipment. The method for data transmission is applied to the terminal equipment and comprises that the terminal equipment is set to be at a first inactive state or a second inactive state when the terminal equipment does not need to send uplink data; the terminal equipment does not monitor paging messages under the first inactive state, monitors paging messages at a preset first monitoring time or first monitoring number of times under the second inactive state and does not monitor the paging messages beyond the first monitoring time or first monitoring number of times, thereby saving the power consumption of the terminal equipment, and saving the electricity consumption; when the terminal equipment needs to send the uplink data, the terminal equipment is set to be at a connection state, and the uplink data is sent when the terminal equipment updates system information; and downlink data cached by the network side equipment when the terminal equipment is under the first inactive state or the second inactive state is received, thereby ensuring transmission of the uplink data and the downlink data.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission method, device, system, network side equipment and terminal equipment. Background technique [0002] In a communication technology network such as the Internet of Things, the terminal device can have two states during the communication process with the application server, namely the inactive (Idle) state and the connection state. In the inactive state, the terminal device and the network side device The connection between them is released, but they will listen to broadcast messages and paging messages; in the connected state, the terminal device will receive all downlink data and can send uplink data. [0003] Generally, terminal devices are powered by batteries. How to save the power of terminal devices communicating in the network is the key to the wide application of terminal devices. In the prior art, terminal devices will enter the In this...
