Problems solved by technology

However, with the development of technology, high-volume applications such as high-definition video, games, etc. emerge in endlessly. Using a single data channel for data transmission, due to the limitation of the maximum capacity of the data channel, still cannot meet the growing needs of users for transmission rates.

Embodiment 1

[0088] Based on the foregoing terminal 100 and network architecture, an embodiment of the present invention provides a data transmission method. The data transmission in the embodiment of the present invention is based on links, that is, when there is a data service to be transmitted, one or more (two or more) links are established, and each link is used to transmit a data packet of a certain size, thereby completing entire data transfer.

[0089] see Figure 4 , the data transmission method of the embodiment of the present invention includes:

[0090] Step S1, detecting the connectivity of each interface in real time.

[0091] It should be understood that detecting the connectivity of the interface is detecting whether the data channel is connected. For example, detecting the connectivity of the WIFI interface is to detect whether it can be connected to the WIFI network through the WIFI data channel for data transmission.

[0092] In an embodiment of the present invention...

Embodiment 2

[0136] The difference between Embodiment 2 of the present invention and the foregoing embodiments is that when calculating the offload weight in Embodiment 2, it is only based on the rate of the interface, without considering the delay. Specifically, see Figure 7 , the data transmission method of this embodiment includes:

[0137] Step S10, detecting the connectivity of each interface in real time.

[0138] Step S20, establishing at least one link when it is detected that there is a data service.

[0139] It should be understood that the specific implementation and details of step S10 and step S20 are the same as those of step S1 and step S2 in the foregoing embodiment, and details are not repeated here.

[0140] Step S30, according to the 1:1 offload weight or the offload weight calculated based on the interface rate, assign the established link to the interface in the connected state to transmit the data service. In the embodiment of the present invention, the offload weig...

Embodiment 3

[0159] see Figure 8 It is a schematic structural diagram of a user equipment with double L function according to an embodiment of the present invention, which includes: a first subscriber identification module 206, a second subscriber identification module 306, a first communication module 801, a second communication module 802, and a switching module 803 , a control module 804 , an application program processing module 202 , a microphone 500 , a codec 204 , a digital signal processing chip 203 , and an earpiece 600 .

[0160] Wherein, the first communication module 801 includes: a first protocol stack 201 and a first radio frequency 205 . The second communication module 802 includes a second protocol stack 301 and a second radio frequency 305 .

[0161] The application program processing module 202 is configured to provide a user interaction interface, and transmit user operation instructions to the control module 804 .

[0162] The control module 804 is configured to outp...

Abstract

The invention discloses a data transmission method and device, a multichannel routing method and user equipment. The data transmission method comprises the following steps: detecting the connectivity of interfaces in real time; establishing at least one link when a data service is detected; and allocating the established link(s) to the interfaces in connection states in order to perform transmission of the data service, according to shunt weight. The data transmission method and device, the multichannel routing method and the user equipment have the beneficial effects that data are transmitted at the same time through a plurality of data channels based on interface rate shunting or based on interface rate and delay shunting; an allocation proportion of data streams is optimized greatly; the congestion, delay and packet loss rates of the interfaces are lowered; and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a data transmission method, device, multi-channel routing method and user equipment. Background technique [0002] With the development of mobile communication technology, advanced cellular networks (eg, networks based on the LTE standard (Long Term Evolution, the standard used by some "4G" networks)) are being deployed all over the world. Due to the introduction of key technologies such as OFDM (Orthogonal Frequency Division Multiplexing, Orthogonal Frequency Division Multiplexing) and MIMO (Multi-Input&Multi-Output, Multiple Input Multiple Output), the spectral efficiency and data transmission rate can be significantly increased by using the LTE standard. [0003] The terminal utilizes the cellular network for data transmission (for example, downloading and uploading), which can greatly improve the user's surfing experience. However, with the developmen...
