Embodiment 1

2 is a flowchart of an embodiment of the present invention. This embodiment discloses a method for a terminal to communicate with each other through a Wi-Fi direct connection technology. As shown in FIG. 2, the method includes:

Step 201: Turn on the terminal directly connected to the Wi-Fi to send a broadcast message. Specifically, after the terminal turns on the Wi-Fi Direct, the information of the terminal is broadcasted through the Wi-Fi Direct protocol, and the information includes a terminal name, an encryption mode, a signal strength, and the like, when the terminal is in a Wi-Fi state. When the change is made, a broadcast message is sent to notify the surrounding terminals.

Step 202: The master control terminal detects the broadcast message sent by the controlled terminal.

Specifically, in this embodiment, by creating a broadcast listener to detect the available peer terminal in the range, if the discovery process is successful and the peer terminal is detected, the broadcast monitor is used to monitor and obtain the discovery terminal message.

Step 203: The master terminal joins the controlled terminal 1 to the communication group according to the monitored broadcast message, establishes a connection with the controlled terminal 1, and acquires the terminal identifier of the controlled terminal 1;

The master terminal establishes a connection with the controlled terminal according to the terminal name of the terminal, and acquires the controlled terminal identifier in the connection process. The controlled terminal is identified as a parameter identifier capable of uniquely determining the controlled terminal, such as an IP address.

Step 204: The master terminal stores an IP address of the master terminal and the controlled terminal in an identifier list.

Step 205: The main control terminal joins the controlled terminal 2 to the communication group according to the monitored broadcast message, establishes a connection with the controlled terminal, and acquires the terminal identifier of the controlled terminal 2; the IP address of the controlled terminal 2 Stored to the list of identifiers;

Similarly, the main control terminal joins the controlled terminal 3 to the communication group according to the monitored broadcast message, establishes a connection with the controlled terminal, and acquires the terminal identifier of the controlled terminal 3; the IP address of the controlled terminal 3 Stored to the list of identifiers;

Step 206: Send the identifier list to the controlled terminal 1 in the communication group, the controlled terminal 2, and the controlled terminal 3;

In this way, each member terminal in the communication group saves the terminal identifiers of other terminals in the group. In this embodiment, the communication group includes a master terminal, a controlled terminal 1, a controlled terminal 2, and a receiver. The four members of the control terminal 3 do not limit the number of group members in the embodiment of the present invention.

Step 207: The group member performs data transmission through the socket. Any member of the group acts as a server, and other members of the group act as clients.

Specifically, a server socket object is created. The server socket object waits for a connection from a client with a specified address and port and blocks the thread until the connection occurs, so it is built in a background thread. ;

Creating a client socket object, where the client socket object uses a specified IP address and port to connect to the server terminal;

Send data from the client to the server. After the client successfully connects to the server terminal, you can send data from the client to the server through the byte stream.

The master terminal and the controlled terminal in the group display both the transmitted and received messages in the visual group interface.

Step 208: Any member of the communication group exits the group communication.

Specifically, the member in the communication group can trigger the group communication to be closed by the corresponding function button or menu item, close the group communication window of the member, and disconnect the other members of the communication group.

Step 209: The process ends.

Embodiment 2

3 is a schematic diagram of data sharing interaction according to an embodiment of the present invention. The embodiment of the present invention discloses a method for sharing data in a group formed by a Wi-Fi Direct connection technology, and the method shown in FIG. 3 includes the following steps. Steps:

Step 301: Any user in the communication group can be regarded as a host user, select other users in the group, and click a data sharing button;

Step 302: The master control terminal sends a data sharing request to the controlled terminal corresponding to other users in the group, and starts to play the video after sending the sharing mode request.

Step 303: The controlled terminal pops up a prompt to the controlled end user, prompting the controlled terminal user to send a response response to the main control terminal.

Step 304: The controlled end user receives the data sharing request, and triggers the controlled terminal to enter Data sharing;

Step 305: After receiving the data sharing request, the controlled terminal sends a response response to the data sharing request to the main control terminal according to the terminal identifier of the main control terminal.

Step 306: After the main control terminal enters the sharing mode, the screen video data is captured and processed. Specifically, the step includes: performing high-speed compression on the video data of the video screen in a preset compression manner, and storing the video data in the storage module. In the middle, the motion compensation coding algorithm and the transform coding are combined, the motion compensation removes the time domain redundancy, the transform coding removes the spatial redundancy, and the combined signal delay of the coding and decoding does not exceed 150 ms.

Step 307: After receiving the signal of receiving the control request, extracting compressed screen video data from the storage module, and transmitting the transmission data through the established channel;

The established channel is a WIFI direct communication channel established by the master control terminal and the controlled terminal.

Step 308: After receiving the high-speed compressed data, the controlled terminal obtains a video digital signal according to a corresponding decompression method;

Step 309: The controlled terminal plays the video, that is, the screen data is obtained by demodulation and played by the local player;

Step 310: The main control user clicks the close data sharing button;

Step 311: The master terminal sends a close data sharing notification to the controlled terminal. Step 312: The controlled terminal receives the closed data sharing notification, exits data sharing, and prompts the controlled end user.

The controlled terminal and the main control terminal can exit the communication mode at any time. When the controlled terminal exits the communication mode, the shared terminal does not affect the sharing of the controlled terminal and other controlled terminals. When the main control terminal exits the communication mode, All controlled terminals will be notified to exit the communication mode.

It should be noted that the communication mode in the embodiment of the present invention includes not only group communication and data sharing, but the embodiment only lists two examples. In the embodiment of the present invention, the communication modes can be simultaneously and combined without conflict, and those skilled in the art do not pay. The modifications made to the embodiments of the present invention under the premise of creative labor are also within the scope of protection of the embodiments of the present invention.

The group communication and the data sharing provided by the embodiment of the present invention can be directly entered by the terminal after the group is established, and the communication modes of the two can be mutually converted. For example, when the master terminal and the controlled terminal are in the group communication mode, the sharing can be triggered. Mode, Similarly, when the master terminal and the controlled terminal are in a shared state, the group communication mode can be triggered in the same manner as the embodiment described above. In the technical solution provided by the embodiment of the present invention, any terminal in the group may be actively initiated to become a master terminal.
