Detailed Description
The invention is described in further detail below with reference to the following figures and specific examples:
the invention relates to a hotspot-free shared mobile phone network surfing system, which comprises a network sharing program module 2 and a virtual network card 5 in a client terminal 1 (intelligent surfing equipment such as a mobile phone, a tablet, a navigator and the like) and a surfing agent program module 4 in a mobile phone 3, wherein a first data communication end of the network sharing program module 2 is connected with a data communication end of the virtual network card 5, and a second data communication end of the network sharing program module 2 is connected with a data communication end of the surfing agent program module 4;
the virtual network card 5 is used for acquiring all IP data packets communicated with the external network of the client terminal 1;
the network sharing program module 2 is used for forwarding the IP data packet to an internet agent program module 4 of the mobile phone 3;
the internet agent program module 4 is used for completing data communication with a destination IP address in the IP data packet by taking the IP address of the internet agent program module as a source address, and sending a data packet responded by a far end back to the network sharing program module 2;
the network sharing program module 2 is further configured to perform packet processing on the received remote response data by using a TCP/IP protocol to obtain a corresponding IP remote response data packet, and write the IP remote response data packet into the virtual network card 5 of the client terminal 1.
In the above technical solution, the virtual network card 5 is further configured to send the IP remote response packet to a corresponding application module 6 in the client terminal 1.
In the above technical solution, the second data communication terminal of the network sharing program module 2 is connected to the data communication terminal of the internet agent program module 4 through a USB (Universal Serial Bus) device, a bluetooth device, or a wifi (Wireless-Fidelity).
In the above technical solution, the virtual network card 5 is a TUN (point-to-point device)/TAP (ethernet device) virtual network device. The TUN/TAP virtual network device provides the transmitting and receiving capability of network data packets for a user space program, and not only Linux supports the TUN/TAP virtual network device, but also other UNIX (time-sharing operating system) supports the TUN/TAP virtual network device. Has good device compatibility.
In the above technical solution, the internet agent program module 4 is only a common network application, and does not need any special authority, thereby facilitating development and deployment of program development.
A hotspot-free shared mobile phone network surfing method comprises the following steps:
step 1: the network sharing program module 2 of the client terminal 1 establishes a data link with the internet agent program module 4 of the mobile phone 3;
step 2: the network sharing program module 2 of the client terminal 1 establishes a virtual network card 5 in the client terminal 1;
and step 3: the virtual network card 5 of the client terminal 1 acquires all IP data packets (from each application program APP in the client terminal 1) communicated with the external network of the local machine of the client terminal 1;
and 4, step 4: the network sharing program module 2 of the client terminal 1 forwards the IP data packet to an internet agent program module 4 of the mobile phone 3 through the data link established in the step 1;
and 5: the Internet agent program module 4 of the client terminal 1 completes data communication with a destination IP address in the IP data packet by using its own IP address as a source address, and sends a data packet (response data on the Internet) of a remote response back to the network sharing program module 2 of the client terminal 1 through the data link in the step 1;
step 6: the network sharing program module 2 of the client terminal 1 performs packet processing on the received remote response data by using a TCP/IP protocol to obtain a corresponding IP remote response data packet, and writes the IP remote response data packet into a virtual network card 5 of the client terminal 1;
and 7: the virtual network card 5 sends the IP remote response packet to the corresponding application module 6 in the client terminal 1.
In the above technical solution, the virtual network card 5 is a TUN/TAP virtual network device, and a character device TUN (TUN network card) in the TUN/TAP virtual network device is used as an interface for exchanging data between a user space and a kernel space. When the kernel sends an IP packet to the TUN/TAP virtual network device, the IP packet is held in a queue associated with the TUN/TAP virtual network device until it is read by the descriptor of the open character device TUN, which is copied to the buffer in user space. The effect is equivalent to that the IP packet is sent directly to the user space. The principle is similar when sending a packet by system call write.
In step 2 of the above technical solution, the method for establishing a virtual network card 5 in the client terminal 1 by the network sharing program module 2 is to add a driver of the TUN/TAP virtual network device and a character device TUN associated with the driver in the kernel of the operating system (Linux system) of the client terminal 1. The location of the character device tun is under the net folder of the dev directory of the client terminal operating system.
The invention mainly utilizes the characteristic of the linux virtual network card to carry out communication, and only one common application network program (an internet agent program module 4) needs to be operated on the mobile phone 3.
The invention can realize the normal internet function of the application of the client terminal, and the mobile phone providing the shared internet does not need to make any special setting, and only needs to run an App with the common internet access authority. For a user, the potential safety hazards such as privacy leakage caused by overhigh application authority are not worried, for a developer, a privileged API is not required to be called, development difficulty is reduced, system integration is facilitated, and applications are put on shelf.
Details not described in this specification are within the skill of the art that are well known to those skilled in the art.
