detailed description

The technical solution of the present application is further elaborated below with reference to the drawings and embodiments.

An embodiment of the present application provides a connection establishment method. FIG. 1A is a schematic diagram of an implementation process of the connection establishment method according to an embodiment of the present application. As shown in FIG. 1A, the method includes steps S101 to S111:

S101. The first device receives an operation instruction, where the operation instruction is used to instruct the first device to establish a P2P connection with the second device;

For example, as shown in FIG. 1B, the P2P connection application interface 101 of the first device displays multiple P2P devices (such as the second device 102, the third device 103, and the fourth device 104) that can establish a P2P connection around it. By connecting to the application interface 101, the user can choose which device to connect to with P2P. For example, the user touches the area where the "second device 102" in the P2P connection application interface 101 is located to trigger the first device to establish a P2P connection with the second device 102.

S102. If the P2P connection information of the second device is not saved in the first device, the first device sends a first group owner (GO, Group Owner) negotiation request (that is, GO Negotiation Request, which is called as follows The first GO negotiation request) to the second device;

There may be two reasons why the first device does not save the P2P connection information of the second device: For example, when the first device establishes a P2P connection with the second device for the first time, the first device The P2P connection information of the second device is not saved in. As another example, when the first device and the second device last established a P2P connection, the first device may not save the P2P connection information of the second device.

S103. The second device responds to the first GO negotiation request and returns a first GO negotiation response (GO Negotiation Response) to the first device;

S104. The first device receives the first GO negotiation response, starts monitoring the channel, and waits to receive the second GO negotiation request sent by the second device;

S105. The second device performs P2P connection initialization;

S106. After the second device completes the initialization of the P2P connection, the second device sends the second GO negotiation request to the first device, where the second GO negotiation request carries the negotiation information of the second device ;

Generally, the negotiation information of the second device includes a P2P Media Access Control (MAC) address of the second device, and a P2P channel supported by the second device.

S107. The first device responds to the second GO negotiation request and returns a second GO negotiation response to the second device, where the second GO negotiation response carries the negotiation information of the first device;

Similarly, the negotiation information of the first device generally includes the P2P MAC address of the first device and the P2P channel supported by the first device.

S108. After receiving the second GO negotiation response, the second device returns a GO negotiation confirmation (GO Negotiation Confirm) to the first device;

It should be noted that, after receiving the second GO negotiation response, the second device can determine the role of P2P connection, such as GO or Group Client (GC, Group Client), if it is GO, waiting to receive the connection request sent by the first device; if it is GC, send the connection request to the first device. In addition, at the same time as the negotiation confirmation, the P2P channel used for the subsequent establishment of the P2P connection is also confirmed.

S109. The second device sends a first connection request to the first device based on the negotiation information of the first device;

Here, it should be noted that the first connection request is used to request to establish a P2P connection with the first device on the P2P channel on which the second device operates, and the first connection request carries the second The P2P MAC address of the device. After receiving the first connection request, the first device sends a first connection response to the second device on the P2P channel on which the second device works based on the P2P MAC address of the second device. The first connection response is used to inform the second device that a P2P connection can be established; after the second device receives the first connection response, the second device returns a second connection response to the first device, At this time, the first device and the second device complete the establishment of the P2P connection.

Suppose that after receiving the second GO negotiation response, the second device determines that it is the role of the client (that is, the second device serves as a GC). At this time, the second device After returning the GO negotiation confirmation, the first connection request is sent to the first device.

S110. The first device receives the first connection request;

S111: The first device establishes a P2P connection with the second device in response to the first connection request.

In an embodiment of the present application, a method for establishing a connection is provided. In this method, before the P2P connection is established between the first device and the second device, if the second device is not saved in the first device P2P connection information, the first device and the second device first need to complete the negotiation process, that is, the above steps S102 to S108, so that it takes a long time to establish a P2P connection between the first device and the second device time.

Based on this, in order to quickly establish a P2P connection between the first device and the second device, an embodiment of the present application provides another connection establishment method, which is applied to the first device, and the first device is The implementation process may be various types of electronic devices with connection establishment capabilities, for example, the first device may include a mobile phone, a tablet computer, a desktop computer, a personal digital assistant, a navigator, a digital phone, a video phone, a television, Sensing equipment, set-top boxes, etc. The function realized by the method can be realized by the processor in the first device calling the program code. Of course, the program code can be stored in a computer storage medium. It can be seen that the first device includes at least a processor and a storage medium.

It should be noted that in all the embodiments provided in this application, if it is a connection response sent by the first device to the second device, it is called a first connection response, if it is a connection response sent by the second device to the first device , Called the second connection response. The functions of the first connection response and the second connection response are the same, both of which are to inform the other party that a P2P connection can be established. For example, both the first connection response and the second connection response carry confirmation information of "OK".

In the embodiment of the present application, when the first device needs to establish a P2P connection with the second device, if the first device does not save the P2P connection information of the second device, the first device does not trigger negotiation Process, that is, not sending a negotiation request to the second device, but directly sending its own P2P connection information to the second device, to trigger the second device based on the P2P connection information of the first device, Sending a first connection request to the first device, so as to quickly realize a P2P connection between the first device and the second device.
