[0098] see figure 1 , is an interactive schematic diagram of a data transmission method provided in this embodiment, and the data transmission method includes the following steps:

[0099] S101: When the data sending device transmits each first data to the data receiving device by using at least one data transmission channel, determine whether data congestion occurs in the data transmission channel, wherein the data type of the first data is the first type of data.

[0100] In this embodiment, the transmission channels used to transmit data are referred to as data transmission channels, and the data sending device may use one or more data transmission channels to transmit data to the data receiving device.

[0101] In this embodiment, the data to be transmitted may be divided into different data types in advance, and each data type corresponds to a different type parameter. For example, assuming that the data to be transmitted is audio data, its audio data types are shown in...

[0122] In this embodiment, the data sending device actively requests the data receiving device to perform congestion detection, and after the data receiving device performs the congestion detection, it notifies the data sending device of the detection result, so that the data sending device maintains or adjusts the data transmission type.

[0123] see figure 2 , is an interactive schematic diagram of a data transmission method provided in this embodiment, and the data transmission method includes the following steps:

[0124] S201: When using at least one data transmission channel to transmit each first data to the data receiving device, the data sending device sends a congestion detection request to the data receiving device, wherein the congestion detection request is used to request the data receiving device to The data transmission channel performs congestion detection.

[0125] It should be noted that, for relevant descriptions about the first data in this embodiment, p...

[0181] In this embodiment, the data receiving device actively performs congestion detection, and notifies the data sending device of the detection result, so that the data sending device maintains or adjusts the data transmission type.

[0182] see image 3 , is an interactive schematic diagram of a data transmission method provided in this embodiment, and the data transmission method includes the following steps:

[0183] S301: When the data receiving device receives each first data transmitted by the data sending device, determine whether data congestion occurs in the data transmission channel.

[0184] It should be noted that, for relevant descriptions about the first data in this embodiment, please refer to the first embodiment, which will not be repeated here.

[0185] In this embodiment, the data receiving device may perform congestion detection on each data transmission channel at a preset time interval, so as to determine whether data congestion occurs on the data tra...

Abstract

The invention discloses a data transmission method, device and system, and the method comprises the steps: judging whether data congestion happens to each data transmission channel or not when data transmitting equipment employs one data transmission channel for transmitting all first data to data receiving equipment; determining a second data type which accords with the transmission capability ofthe data transmission channel according to a judgment result; and transmitting all to-be-transmitted second data to the data receiving equipment through at least one data transmission channel. Therefore, the method achieves the detection of the network congestion, and changes or maintains the current data transmission type according to the congestion condition, so as to guarantee the smooth transmission of data. Moreover, the method improves the quality of transmitted data under the condition that the smooth transmission is guaranteed.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a data transmission method, device and system. Background technique [0002] At present, in the process of transmitting data through the wireless network, due to the interference of the network signal by the environment and other wireless signals, the network will experience transmission delays and changes in transmission throughput. This unstable network will lead to fast and slow transmission phenomenon. [0003] Especially in the process of transmitting audio data, the fluctuation of network quality will directly affect the stability of audio data. This is because, if the network is poor and cannot meet the bandwidth requirements of real-time audio transmission, there will be sound on the audio playback end. Caton phenomenon, which reduces the user experience. Contents of the invention [0004] The main purpose of the embodiments of the present appli...
