[0076] Such as image 3 As shown, the first embodiment of the data transmission method of the present invention is proposed, and the method includes the following steps:

[0077] S11. Bind the application to the data channel.

[0078] Specifically, the binding of the application and the data channel can be realized by establishing a corresponding relationship table between the application and the data channel, and the binding of the application and the data channel can also be realized by setting routing rules. There are at least two data channels, including 4G channels (such as LTE), 3G channels, WIFI channels, and the like.

[0079] When binding the application and the data channel, it is preferable to use the unique identifier of the application to bind the application and the data channel. Taking the Android system as an example, each application in the Android system has a Uid (UserIdentification, user identification). By default, the Android system will assign a differ...

[0082] Such as Figure 4 As shown, the second embodiment of the data transmission method of the present invention is proposed, and the method includes the following steps:

[0083] S21. Establish a correspondence relationship table between applications and data channels.

[0084] In this embodiment, the binding applied to the data channel is realized by establishing a correspondence table between the application and the data channel.

[0085] For example, the correspondence table between an application and a data channel is as follows Figure 5 As shown, the data channel includes an LTE channel and a WIFI channel, wherein application 1 to application n are bound to the WIFI channel, and application (1) to application (n) are bound to the LTE channel.

[0086] S22. When each application executes the data service, query the corresponding relationship table to obtain the data channel corresponding to each application.

[0087] S23. Use the data channel corresponding to each ap...

[0091] Such as Figure 7 As shown, the third embodiment of the data transmission method of the present invention is proposed, and the method includes the following steps:

[0092] S31. Set routing rules, and bind the application to the data channel.

[0093] In this embodiment, the binding of applications and data channels is realized by setting routing rules, that is, the routing rules are used to control the routing selection of each application when transmitting data, and then guide the data packets of each application to the corresponding data channel.

[0094] Wherein, the setting of the routing rule can be realized by adding the unique identifier of the application to the routing table of the network card of the data channel. For example, the unique identifier of a certain application may be added to the routing table of the LTE network card, and the unique identifier of another application may be added to the routing table of the WIFI network card.

Abstract

The invention discloses a data transmission device and method. The device comprises a data channel binding module for binding an application to at least two data channels, and a data service management module for transmitting the data of the application by use of the data channels bound to the application when a data service is executed by the application. As a result, a terminal is capable of concurrently accessing to the Internet via a plurality of data channels, and the data channels are capable of transmitting data without mutual interference with each other while the data throughput of the terminal is increased; besides, each application performs downloading and caching operations by use of different data channels simultaneously so that the downloading interaction rate of the terminal can be multiplied. As a result, the Internet resources are utilized thoroughly, the rate of accessing to the Internet is increased and the experience of accessing to the Internet is enhanced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a data transmission device and method. Background technique [0002] At present, the mobile terminal can use the 2G, 3G, 4G network of the SIM card and the WIFI (WIreless-Fidelity, wireless fidelity) network of the WIFI network card to access the Internet. The data channels corresponding to each network are 2G channel, 3G channel, 4G channel and WIFI access, etc. [0003] In the prior art, when there are multiple networks at the same time, the mobile terminal generally only selects the data channel of one of the networks for data transmission. For example, when both the 4G network and the WIFI network are available, the mobile terminal generally chooses the WIFI channel of the WIFI network for data transmission. For data transmission, when there is no WIFI network or the WIFI network function is turned off, the mobile terminal uses the data channel of the 4G netwo...
