Embodiment 1

[0038] like figure 1 As shown, the data transmission system provided by the embodiment of the present invention includes a client device 110, an access gateway 120, and an operator network 140. There may be one or more client devices 110, which are respectively connected to the access gateway 120, access The gateway 120 is further connected to the operator's network 140 through a DSL (Digital Subscriber Line) channel and an LTE (LongTermEvolution, fourth-generation communication technology) channel, so that the client device 110 can obtain from the operator's network 140 through the access gateway 120 Data, local data can also be uploaded to the operator network 140 through the access gateway 120 , so as to realize data transmission and reception between the client device 110 and the operator network 140 .

[0039] The access gateway in the embodiment of the present invention has two paths of DSL channel and LTE channel to connect with the operator network. When the network tr...

Abstract

The embodiment provided by the invention discloses a data transmission method, device and system. The method comprises that an access gateway receives data messages; the access gateway transmits the data messages to an operator network through a digital subscriber line DSL channel; the access gateway detects the bandwidth occupation conditions when transmitting the data messages on the DSL channel; the access gateway determines that the DSL channel cannot satisfy a subscriber demand and needs to overflow partial data traffics; the access gateway overflows the data messages needing to be overflowed to an LTE (Long Term Evolution) transmission channel, wherein the data messages are transmitted to the operator network in a DSL channel and LTE channel combined mode. According to the embodiment provided by the invention, if detecting that the bandwidth for transmitting the data in the DSL mode cannot satisfy the subscribe demand, an LTE transmission module is automatically booted; therefore, the transmission bandwidth is increased; the data transmission efficiency is improved; moreover, the LTE using cost is effectively prevented from rising greatly; and the user experience is promoted.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, to a data transmission method, device and system. Background technique [0002] DSL (Digital Subscriber Line, Digital Subscriber Line) is cheap because of its simple wiring. DSL is a common method of network connection, especially ADSL, which is the main means of network connection for families or businesses. It has a large downstream bandwidth and is suitable for daily life such as network surfing and network data acquisition. With the development of digital technology and media technology, such as video conferencing and high-simulation interaction, the demand for user access bandwidth is getting higher and higher. However, due to the limitations of DSL technology itself, the maximum bandwidth that DSL can provide is very limited. For example, the theoretical uplink bandwidth of ADSL is only 2Mbps, which is difficult to meet the needs of media applications. ...
