Problems solved by technology

[0004] In the prior art, based on the virtual network card set on the terminal side, the terminal performs network layer switching between heterogeneous networks. During the data transmission process, it is necessary to re-establish the IP address information corresponding to the obtained new network link. Communication network link, so switching efficiency is relatively low

Embodiment 1

[0024] like figure 1 As shown, in Embodiment 1 of the present invention, a system architecture diagram for data transmission based on different links between heterogeneous networks is proposed, including terminals, virtual network cards, link management devices, first communication network network cards and their corresponding Access network, network card of the second communication network and its corresponding access network, terminal link queue management equipment, data gateway, wherein:

[0025]A terminal is a terminal that can be inserted into at least two network cards and can be connected to the corresponding network side through any network card, wherein at least two network cards can be communication network cards corresponding to different communication systems, for example, it can be a desktop computer equipped with a network card , laptops, mobile phones, etc.

[0026] A virtual network card is a virtual network card device set on a terminal device, and its form ...

Embodiment 2

[0038] Furthermore, Embodiment 2 of the present invention is based on the system for data transmission based on different links between heterogeneous networks introduced in Embodiment 1 above. Taking two physical network cards of TD-SCDMA and WLAN inserted into the terminal as an example, the system based on A method for data transmission between different network links between heterogeneous networks, such as figure 2 As shown, the specific process is as follows:

[0039] Based on the system architecture in the first embodiment above, in the uplink:

[0040] In step 201, the link management device receives the message sent by the terminal to the network side based on the address of the virtual network card. For example, based on the address of the virtual network card, the terminal sends an access request packet to the network side to access a certain web page.

[0041] Step 202, the link management device selects one or more communication network links respectively corresp...

Embodiment 3

[0074] Further, based on the steps 201 to 204 in the second embodiment of the above method, corresponding to the terminal side, the third embodiment of the present invention proposes a method in the uplink of message transmission (that is, the message is transmitted from the terminal side to the network side) ), a device for data transmission based on different links between heterogeneous networks, its structure is as follows Figure 4 shown, including:

[0075] The receiving unit 401 is configured to receive a message sent by the terminal to the network side based on the address of the virtual network card.

[0076] The link management unit 402 is configured to select a communication network link among the communication network links corresponding to at least two network cards inserted in the terminal, wherein the communication network links corresponding to the at least two network cards inserted in the terminal are heterogeneous networks different links between.

Abstract

The invention discloses a method, a device and a system for data transmission based on different links between heterogeneous networks. The method comprises the steps that a receiving terminal sends a message to a network side based on a virtual network card address; one of communication network links corresponding to at least two network cards inserted at the terminal respectively is selected, wherein the communication network links corresponding to at least two inserted network cards respectively are different links between the heterogeneous networks; the virtual network card address serving as a source address in the message is converted to a network card address of the network card corresponding to the selected communication network link; and the message after source address conversion is sent to the network side through the selected communication network link. With the adoption of the technical scheme, the switching efficiency of different communication network links between the heterogeneous networks can be improved better.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device and system for data transmission based on different links between heterogeneous networks.
