With the popularization of network use in the current society, people use more and more vehicle-mounted multimedia networking functions, and the vehicle-mounted multimedia networking functions are also more and more popularized, but the 4G network module or the WIFI module is required to be added to vehicle-mounted multimedia, so that the cost pressure of the vehicle-mounted multimedia is increased. And with the requirement of the country for the network to use the real name system, the user needs to additionally increase the registration procedure, which causes inconvenience or incapability of using the network.
Although some car factories provide free network for use in a limited period, users are required to pay after the period is over, so that the use cost of the users is increased, and most of the traffic of mobile phone users is included in a package at present, so that additional cost is not increased.
The mobile phone is connected through the vehicle-mounted multimedia USB line, the mobile phone network is shared through the USB line, so that the user can normally use the vehicle-mounted multimedia network function, extra network cost of the user is not increased, the cost of the 4G module or the WIFI module is not increased for the vehicle-mounted multimedia machine, and the cost pressure of the vehicle-mounted multimedia host is greatly reduced. The technical scheme can effectively solve the problem of network functions of a user, and simultaneously solves the problem of cost pressure of the vehicle-mounted multimedia host on the premise of no change of other experiences; thereby effectively solving the contradiction between the improvement of functional requirements and the cost pressure; has wide market prospect.
As shown in fig. 1, an application scenario of the network sharing technical solution provided in the embodiment of the present invention includes a vehicle-mounted multimedia host, a mobile terminal device, and a USB device; the vehicle-mounted multimedia host system is a system with an android version of more than 4.0; the mobile terminal device comprises an intelligent communication device or a wearable device, wherein the intelligent terminal device or the wearable device can be an intelligent device of an android operating system or an intelligent device of an IOS operating system; the USB device is required to be able to pass the eye test normally.
Specifically, an embodiment of the present invention provides a method for a vehicle-mounted multimedia host and a mobile terminal to share a network, where as shown in fig. 2, the method includes:
s202, when the vehicle-mounted multimedia host is successfully physically connected with the mobile terminal and the VPN application on the vehicle-mounted multimedia host acquires trigger information of the VPN application on the mobile terminal, the VPN application on the vehicle-mounted multimedia host establishes virtual private network connection; wherein, the vehicle-mounted multimedia host and the mobile terminal have the same VPN application.
The vehicle-mounted multimedia host supports the creation of the virtual private network VPN in versions above android4.0, and particularly the host of the versions above android4.0 is provided with a public API (application programming interface) application program interface, so that a third party application is allowed to realize a VPN virtual network connection solution.
It should be noted that the vehicle-mounted multimedia host and the mobile intelligent terminal in the embodiment of the present invention both have the same VPN third-party application for performing virtual private network connection.
Correspondingly, in step S202, the vehicle-mounted multimedia host detects that the USB device is inserted, successfully identifies that the other end of the USB device is a mobile terminal (such as a mobile phone), and detects that when the VPN application of the mobile terminal is operated to be opened, the VPN application on the vehicle-mounted multimedia host can establish the virtual private network connection in a state that the vehicle-mounted multimedia host and the intelligent terminal are successfully connected through the USB device.
S204, calling an application program standard interface corresponding to virtual private network connection by the VPN application on the vehicle-mounted multimedia host, and creating a standard virtual network card according to the application program standard interface;
specifically, the standard interface of the application program corresponding to the virtual private network connection in step S202 is a vehicle-mounted native API interface, such as a public synchronized laptop preparation (String old package) or a public synchronized particlebell filedescriptor update (VpnConfig configuration). And calling the API interface through a software program calling logic so as to prepare for VPN virtual private network connection.
It should be noted that the API interface can also be used to check whether a virtual private network VPN connection already exists on the current host system; when the same third-party application creates a VPN connection, the bottom layer informs the existence of the VPN of the third-party application (VPN application), and the third-party application does not establish a new VPN after receiving feedback or uses the previously established VPN. For example, when a VPN connection already exists on the host system, after step S202, the step S204 is completed, and the VPN application on the vehicle-mounted multimedia host calls the application standard interface, at this time, the VPN application on the multimedia host system is embodied on the interface through an interface message, for example, in a dialog box form, so as to notify the user; while the VPN application does not create a VPN connection.
The API can also detect whether the same third-party application on the vehicle-mounted host computer is created and further fed back to the third-party application; because the VPN application on the on-board host and the VPN application on the mobile terminal belong to the same third party application; at this time, if the VPN application on the in-vehicle host is different from the VPN application on the mobile terminal, the VPN connection is not created by the VPN application on the in-vehicle multimedia host at this time.
In the embodiment of the invention, the problem of communication disorder caused by the fact that a plurality of VPNs are created on the vehicle-mounted multimedia host system can be prevented by calling the API.
The standard virtual network card in the embodiment of the present invention may be a tun0 virtual network card capable of performing effective gateway communication; since the on-board host system (system above android 4.0) only allows one virtual private network VPN connection at a time, when a new network card tunX (a network card other than the tun0 virtual network card) is created, the existing virtual network card (tun0 virtual network card) will fail.
S206, the vehicle-mounted multimedia host machine configures network connection information for local by using the standard virtual network card and a TCP/IP standard protocol, so that the local network connection information and the network connection information of the mobile terminal are in the same network segment;
wherein, the network data is transmitted by using a network card as a medium; a valid network card must be configured with IP and routing to identify and communicate in the lan.
Accordingly, in step S206, network connection information is configured for the vehicle-mounted multimedia host by using the standard virtual network card and the TCP/IP standard protocol. Because the VPN application of the vehicle-mounted multimedia is the same as that of the mobile phone, the mobile intelligent terminal physically connected with the multimedia host has the network connection information of the same network segment while the standard virtual network card and the TCP/IP standard protocol are utilized to configure the network connection information for the vehicle-mounted multimedia host.
Wherein the network connection information comprises an IP address and routing information; when the IP addresses are in the same network segment, the IP addresses correspondingly belong to the same route.
That is, based on steps S202-S206, the IP address of the mobile terminal is automatically realized, and is in the same network segment as the IP address of the vehicle-mounted multimedia host; thereby realizing the network communication and the network sharing in the following step S208.
And S208, the vehicle-mounted multimedia host and the mobile terminal establish network communication to carry out network sharing.
Specifically, after the vehicle-mounted multimedia host and the mobile terminal can be in network sharing, the shared information of the vehicle-mounted multimedia host and the mobile terminal can be stored so as to be used for directly calling the last shared information from the storage device during subsequent re-sharing, so that the efficiency of information transmission of the vehicle-mounted multimedia host and the mobile terminal is improved, the time of a user is saved, and the experience degree and the viscosity of the user are further improved.
Specifically, the network communication is established between the vehicle-mounted multimedia host and the mobile terminal, and the network sharing is performed, including: and mapping the display picture of the mobile terminal to the vehicle-mounted multimedia host to perform same-screen interaction.
An embodiment of the present invention further provides a method for network sharing between a vehicle-mounted multimedia host and a mobile terminal, as shown in fig. 3, the method includes the steps involved in the vehicle-mounted multimedia host, and specifically, the method includes:
s402, when physical connection information with a mobile terminal is acquired and a local VPN application acquires trigger information of the VPN application on the mobile terminal, establishing virtual private network connection;
s404, calling an application program standard interface corresponding to virtual private network connection, and creating a standard virtual network card according to the application program standard interface;
s406, local network connection information is configured for the local by using the standard virtual network card and a TCP/IP standard protocol, so that the local network connection information and the network connection information of the mobile terminal are in the same network segment;
and S408, establishing network communication with the mobile terminal to perform network sharing.
Further, as shown in fig. 4, step s408, establishing network communication with the mobile terminal for network sharing, and then:
and S410, storing network sharing information with the mobile terminal, wherein the network sharing information comprises image information and audio information.
In the embodiment of the invention, the data transmission between the mobile terminal and the vehicle-mounted host is realized by taking the created virtual network card as an intermediate medium through a standard program interface; network modules such as 4G or WIFI (wireless fidelity) and the like do not need to be added to the vehicle-mounted host; the network resources of the intelligent terminal can be fully utilized, the network resources are not wasted, and the plug and play is convenient and quick; the network of the mobile terminal is shared through the USB, so that the vehicle-mounted host is not interfered by the wiring inside the vehicle body and electromagnetic signals of other vehicle body electrical appliances, and the network signals of the multimedia host are enhanced.

Further, in step S604, the invoking of the previous network sharing information with the mobile terminal specifically includes:
when detecting that the connection between the vehicle-mounted multimedia host and the mobile terminal is not the first connection, displaying and outputting verification information of whether the previous network sharing information of the vehicle-mounted multimedia host and the mobile terminal is recovered;
and when the confirmation information for recovering the previous network sharing information is acquired, calling the previous network sharing information of the vehicle-mounted multimedia host and the mobile terminal.
As shown in fig. 6, fig. 6 is a schematic diagram of information transmission of a network shared by a vehicle-mounted multimedia host and a mobile terminal, where USB mux is a USB wire harness, and Proxy Server is a Proxy Server in a mobile phone operating system, and is used for acting on a network user of the vehicle-mounted multimedia host to obtain network information, so that the vehicle-mounted multimedia host obtains the network information from the mobile terminal.
