Please refer to FIG. 1 , which is a schematic diagram of a data transmission system. Those skilled in the art can understand that the data transmission device 100 in the system shown in FIG. 1 does not limit the devices applicable to this application, and the data transmission device may include more or less components than those shown in the figure, or combine some components , or different component arrangements.

The data transmission device 100 includes an establishment module 102, a network card module 104 and a control plane (Control Plane, CP) module 106.

Wherein, the establishment module 102 is connected to the network card module 104, and the network card module 104 is connected to the control plane module.

Setting up module 102 can carry out packet data protocol (packet data protocol, PDP) context activation by AT command, set up session, each session can correspond to a calling identity delivery (CID), as shown in Figure 1, {CID1 ;CID2;...;CIDn}. At the same time, multiple public data network connections are established with the network equipment, and multiple virtual network cards are mapped; wherein, each virtual network card includes a caller identification mark, and each virtual network card corresponds to a unique IP address.

The network card module 104 provides a virtual network card for the application data, and sends the application data through the IP address corresponding to the virtual network card. The network card module 104 can store a virtual network card list, and the virtual network card list can store the corresponding relationship between each virtual network card and each IP address. Wherein, each virtual network card includes a subscriber identification module identity (SIMID) in addition to a caller identification identifier (CID). Correspondingly, the control plane module 106 receives the data sent by the network card module 104, and may send the application data to the network (network, NW) according to the route corresponding to the carried IP address. Suppose the virtual network card is marked as netif, such as: netif1, netif2, ..., netifn; each IP address, such as: IP1, IP2, ..., IPn; the two identifiers that can be bound to a virtual network card netif are respectively recorded as cid and simid, then , as shown in Figure 1, the list of virtual network cards that can be stored in the network card module 104 netif_list {netif1 (cid1, simid) --- IP1; netif2 (cid2, simid) --- IP2; ... netifn (cidn, simid) --- -IPn}.

Wherein, the network (network, NW) also includes an ESM unit, an EMM unit and an AS unit.

Currently, which virtual network card in the network card module 104 is newly activated, the application data is sent by the newly activated virtual network card by default. Wherein, the newly activated virtual network card can use its corresponding IP address to send the application data. Assuming that the newly activated virtual network card netif1 in the virtual network card list netif_list, then, as shown in FIG. IP1 sends the application data out. It can be seen that since all application data is sent through the newly activated virtual network card, the IP bearer corresponding to the newly activated virtual network card cannot distinguish whether the destination address of the application data is a public network or a private network card network, and thus cannot accurately send the data.

This application provides a data transmission method and related equipment, which can establish multiple public data network connections with network equipment, and map multiple virtual network cards; The virtual network card has a unique IP address; determine the caller ID corresponding to the application data according to the type of application data, determine the corresponding virtual network card according to the caller ID, and determine the corresponding IP address according to the virtual network card; bind the IP address , and send the corresponding application data through the IP address, so as to accurately send the application data.

Furthermore, the adaptation module 204 distributes the application data to different virtual network cards.

For example, if the type of the application data is FTP, then the terminal device determines that the caller ID corresponding to the FTP is the caller ID 1 according to the corresponding relationship, and uses the caller ID 1 as the caller ID corresponding to the FTP application data. Similarly, when the type of application data is HTTP, MQTT, LWM2M, NTP, SMTP, and DNS, the terminal device determines the caller ID corresponding to the application data according to the corresponding relationship.

S408: Determine whether to establish multiple public data network (PDN) connections, if no multiple public data network connections are established, then perform steps S410 and S412; if multiple public data network connections are established, then perform steps S414 to S418.

S410: Map a unique virtual network card, and the virtual network card corresponds to a unique IP address.

For example, suppose the unique virtual network card is marked as Single netif, and the Single netif corresponds to a unique IP address.

S412: Bind to the unique IP address, and send all application data through the unique IP address.

S414: Establish multiple public data network connections with the network device, and map multiple virtual network cards.

In an optional implementation manner, a plurality of virtual network cards form a virtual network card list, and the virtual network card list may store correspondences between each virtual network card and each IP address. Optionally, each virtual network card has two identifiers, one of which is a CID and the other is a SIMID. For example, assume that the virtual network card is marked as netif, such as: netifx, netify, ..., netifz; each IP address, such as: IPx, IPy, ..., IPz; the two identifiers that can be bound to a virtual network card netif are respectively recorded as cid and simid , then, the list of virtual network cards that can be stored in step S414 is netif_list{netifx(cidx, simid)---IPx; netify(cidy, simid)---IPy;...netifz(cidz, simid)---IPz;} .
