Background
The Wireless Fidelity Direct (WFD) standard refers to allowing electronic devices in a Wireless network to connect to each other without passing through a Wireless router. Similar to bluetooth technology, this standard allows point-to-point (P2P, Peer-to-Peer) interconnection among multiple electronic devices. Compared with a bluetooth connection link, a direct connection link based on WiFi (i.e., a P2P connection link) has better data transmission speed, transmission distance, etc. than the bluetooth connection link, and thus is widely used. For example, WFD technology can be used to enable a user's laptop computer to bypass the access point and establish a P2P connection directly with a wireless printer, digital camera, projector, sensor, or television box, etc.
At present, when a first device needs to establish a P2P connection with a second device, in a normal situation, if the first device does not store P2P connection information of the second device, the first device needs to negotiate with the second device first, and after the first device establishes respective roles through negotiation and obtains P2P connection information of the second device, the P2P connection with the second device can be achieved.
However, the process of the first device completing the negotiation with the second device takes a long time, which is not favorable for the first device to quickly establish the P2P connection with the second device.

Detailed Description
The technical solution of the present application is further elaborated below with reference to the drawings and the embodiments.
An embodiment of the present application provides a connection establishment method, and fig. 1A is a schematic flow chart illustrating an implementation of the connection establishment method according to the embodiment of the present application, where as shown in fig. 1A, the method includes steps S101 to S111:
s101, a first device receives an operation instruction, wherein the operation instruction is used for indicating the first device to establish P2P connection with a second device;
for example, as shown in fig. 1B, a plurality of P2P devices (e.g., a second device 102, a third device 103, and a fourth device 104) capable of establishing a P2P connection are displayed on the P2P connection application interface 101 of the first device, so that, based on the P2P connection application interface 101, the user can select which device to perform a P2P connection with, for example, by touching an area where "the second device 102" is located in the P2P connection application interface 101, the first device is triggered to establish a P2P connection with the second device 102.
S102, if the first device does not store the P2P connection information of the second device, the first device sends a first Group Owner (GO) Negotiation Request (hereinafter referred to as a first GO Negotiation Request) to the second device;
there may be two reasons why the P2P connection information of the second device is not stored in the first device: for example, when the first device establishes a P2P connection with the second device for the first time, the P2P connection information of the second device is not stored in the first device. As another example, the first device may not maintain the P2P connection information of the second device when the first device and the second device last established a P2P connection.
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 to monitor a channel, and waits for receiving a second GO negotiation request sent by the second device;
s105, the second equipment executes P2P connection initialization;
s106, after the second device completes initialization of P2P connection, the second device sends the second GO negotiation request to the first device, where the second GO negotiation request carries 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, wherein the second GO negotiation response carries negotiation information of the first device;
similarly, the negotiation information of the first device generally includes the P2P MAC address of the first device, the P2P channels supported by the first device.
S108, after receiving the second GO Negotiation response, the second device returns a GO Negotiation confirmation (GO Negotiation confirmation) to the first device;
it should be noted that, after receiving the second GO negotiation response, the second device may determine that the role in P2P connection is the GO or the Group Client (GC), and if the role is the GO, wait to receive the connection request sent by the first device; if it is GC, a connection request is transmitted to the first device. In addition, the confirmation is negotiated, and simultaneously, the P2P channel used for subsequently establishing 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 that a P2P connection is established with the first device on a P2P channel where the second device operates, and the first connection request carries a P2P MAC address of the second device. After receiving the first connection request, the first device sends a first connection response to the second device on a P2P channel on which the second device operates based on a P2P MAC address of the second device, wherein the first connection response is used for informing that the second device can establish a P2P connection; after receiving the first connection response, the second device returns a second connection response to the first device, and at this time, the first device and the second device complete the establishment of the P2P connection.
Assuming that the second device determines that the second device is in a role of a client (i.e., the second device serves as a GC) after receiving the second GO negotiation response, at this time, the second device sends the first connection request to the first device after returning a GO negotiation confirmation to the first device.
S110, the first device receives the first connection request;
and S111, the first device responds to the first connection request and establishes P2P connection with the second device.
In this embodiment, before establishing a P2P connection with the second device, if the P2P connection information of the second device is not stored in the first device, the first device and the second device first need to complete a negotiation procedure, that is, the foregoing steps S102 to S108, first, so that it takes a long time for the first device to establish the P2P connection with the second device.
Based on this, in order to quickly establish a P2P connection between the first device and the second device, the present embodiment provides another connection establishment method, which is applied to the first device, and the first device may be various types of electronic devices with connection establishment capability in the implementation process, 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, a sensing device, a set-top box, and the like. The functions implemented by the method may be implemented by a processor in the first device calling program code, which may of course be stored in a computer storage medium, and the first device may, as seen, comprise at least a processor and a storage medium.
Fig. 2 is a schematic flow chart illustrating an implementation of another connection establishment method according to an embodiment of the present application, and as shown in fig. 2, the method includes steps S201 to S204:
s201, a first device receives an operation instruction, wherein the operation instruction is used for indicating the first device to establish P2P connection with a second device;
here, the first device determines whether it holds the P2P connection information of the second device in response to the operation instruction, and proceeds to step S202 if it does not hold the P2P connection information of the second device. If the first device itself stores the P2P connection information of the second device, the first device sends a second connection request to the second device to request to establish a P2P connection with the second device based on the P2P connection information of the second device.
S202, if the P2P connection information of the second device is not stored in the first device, the first device sends the P2P connection information of the first device to the second device to trigger the second device to send a first connection request to the first device based on the P2P connection information of the first device;
generally, the P2P connection information of the first device includes a P2P MAC address of the first device, a P2P channel supported by the first device, and a role (generally GO) when the first device makes a P2P connection with the second device. It can be understood that, if the P2P connection information of the second device is not stored in the first device, the first device skips the process of negotiating with the second device and directly sends its P2P connection information to the second device, thereby triggering the second device to send a first connection request to the first device based on the P2P connection information of the first device, and quickly establishing a P2P connection with the second device; the first connection request and the first device establish a P2P connection on a P2P channel where the second device operates, where the first connection request carries a P2P MAC address of the second device.
It should be noted that, in all the embodiments provided in this application, if the connection request is sent from the second device to the first device, it is referred to as a first connection request, and if the connection request is sent from the first device to the second device, it is referred to as a second connection request.
S203, the first device receives the first connection request;
s204, the first device responds to the first connection request and establishes P2P connection with the second device.
It can be understood that, after receiving the first connection request, the first device sends a first connection response to the second device on a P2P channel where the second device operates based on a P2P MAC address of the second device, where the first connection response carries information that a P2P connection can be established with the second device, that is, the first connection response is used for informing that the second device can establish a P2P connection; after receiving the first connection response, the second device returns a second connection response to the first device, where the second connection response carries information confirming establishment of the P2P connection, that is, the second connection response is used to inform the first device that the P2P connection is successfully established, and at this time, the first device and the second device complete establishment of the P2P connection.
It should be noted that, in all the embodiments provided in this application, if the connection response is sent by the first device to the second device, the connection response is referred to as a first connection response, and if the connection response is sent by the second device to the first device, the connection response is referred to as a second connection response. The first connection response and the second connection response have the same function, and both are used for informing the opposite side that the P2P connection can be established. For example, both the first connection response and the second connection response carry "OK" confirmation information.
In this embodiment of the present application, when a first device needs to establish a P2P connection with a second device, if the first device does not store P2P connection information of the second device, at this time, the first device does not trigger a negotiation process, that is, does not send a negotiation request to the second device, but directly sends its P2P connection information to the second device, so as to trigger the second device to send a first connection request to the first device based on the P2P connection information of the first device, thereby quickly implementing the P2P connection between the first device and the second device.
The embodiment of the present application provides a further connection establishment method, and fig. 3 is a schematic flow chart illustrating an implementation of the further connection establishment method provided in the embodiment of the present application, and as shown in fig. 3, the method includes steps S301 to S308:
s301, a first device receives an operation instruction, wherein the operation instruction is used for indicating the first device to establish P2P connection with a second device;
s302, the first device detects whether the P2P connection information of the second device is saved or not; if yes, go to step S303; otherwise, executing step S306;
s303, the first device sends a second connection request to the second device to request to establish a P2P connection with the second device based on the P2P connection information of the second device, and then the step S304 is carried out;
in general, regardless of whether the P2P connection information of the second device includes the role played by the second device when performing P2P connection, if the P2P connection information of the second device includes the P2P MAC address of the second device and the P2P channel supported by the second device, the first device may send a second connection request to the second device based on the two information. The second connection request is used for requesting the second device to establish a P2P connection on a P2P channel where the first device operates, and the second connection request carries a P2P MAC address of the first device. After receiving the second connection request, the second device sends a second connection response to the first device on a P2P channel on which the first device operates based on the P2P MAC address of the first device, wherein the second connection response is used for informing that the first device can establish a P2P connection; after receiving the second connection response, the first device returns a first connection response to the second device, and at this time, the second device and the first device complete the establishment of the P2P connection.
S304, the first device detects whether a connection response fed back by the second device based on the second connection request (i.e. the second connection response) is received within a preset time period; if yes, go to step S305; otherwise, executing step S306;
s305, the first device establishes a P2P connection with the second device based on the connection response;
s306, the first device sends the P2P connection information of the first device to the second device to trigger the second device to send the first connection request to the first device based on the P2P connection information of the first device, and then the step S307 is carried out;
it is to be understood that, if the P2P connection information of the second device is already saved in the first device, after the second connection request is sent to the second device, if the second device does not respond for a long time, at this time, the first device does not perform a negotiation process, but sends its P2P connection information to the second device to trigger the second device to send the first connection request to the first device based on the P2P connection information of the first device, thereby implementing a fast P2P connection.
Generally, after the first device sends the second connection request to the second device, the second device does not respond for a long time, which may be because the P2P connection information of the first device is not saved in the second device or the second device cannot operate on the P2P channel used by the current P2P connection.
S307, the first device receives the first connection request;
s308, the first device responds to the first connection request and establishes P2P connection with the second device.
An embodiment of the present application provides another connection establishment method, and fig. 4 is a schematic flow chart illustrating an implementation of another connection establishment method provided in the embodiment of the present application, where as shown in fig. 4, the method includes steps S401 to S407:
s401, a first device receives an operation instruction, wherein the operation instruction is used for indicating the first device to establish a P2P connection with a second device;
s402, if the P2P connection information of the second device is not stored in the first device, the first device detects whether the first device and the second device have an established non-P2P connection link; if yes, go to step S403; otherwise, go to step S404;
it should be noted that, if the P2P connection information of the second device is already stored in the first device, but after the first device sends the second connection request to the second device based on the P2P connection information of the second device, if the first device does not receive the connection response fed back by the second device based on the second connection request within a preset time period, the first device may also send its P2P connection information to the second device in steps S403 to S405 or in a broadcast manner.
For example, the non-P2P connection link may be an infrared link, a Near Field Communication (NFC) link, a bluetooth Socket link, or the like.
S403, the first device sends the P2P connection information of the first device to the second device through the non-P2P connection link, and then the step S406 is carried out;
s404, the first device and the second device establish the non-P2P connection link;
in other embodiments, if there is no established non-P2P connection link between the first device and the second device, the first device may further send the P2P connection information of the first device to the second device in a broadcast manner, that is, the first device broadcasts its P2P connection information, and if the second device receives the P2P connection information of the first device, the second device sends a first connection request to the first device based on the P2P connection information of the first device. Generally, when the second device receives the P2P connection information of the first device, if the second device is idle at this time (e.g., the second device does not currently establish a P2P connection with another device, or the second device currently establishes a P2P connection with another device, but the number of devices connecting the second device through the P2P does not exceed a preset threshold), the second device sends a first connection request to the first device.
S405, the first device sends the P2P connection information of the first device to the second device through the established non-P2P connection link;
generally, the first device does not need to negotiate with the second device when establishing the non-P2P connection link, thus saving the time consumed for negotiation. Establishing a non-P2P connection link between the first device and the second device, for example, via Bluetooth Low Energy (BLE) technology.
In other embodiments, in order to reduce power consumption of the first device and the second device, in a normal case, after the first device sends the P2P connection information of the first device to the second device through the established non-P2P connection link, the non-P2P connection link is disconnected.
S406, the first device receives a first connection request sent by the second device to the first device based on the P2P connection information of the first device;
s407, the first device responds to the first connection request, and establishes a P2P connection with the second device.
The embodiment of the present application provides another connection establishment method, which is applied to a second device, where the second device may be various types of electronic devices with connection establishment capability in the implementation process, 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, a sensing device, a set-top box, and the like. The functions implemented by the method may be implemented by a processor in the first device calling program code, which may of course be stored in a computer storage medium, and the first device may, as seen, comprise at least a processor and a storage medium.

s501, a second device receives P2P connection information of a first device, wherein the P2P connection information of the first device is sent by the first device when the P2P connection information of the second device is not saved;
in other embodiments, the P2P connection information of the first device received by the second device may also be sent by the first device in the following example, that is: the P2P connection information of the second device is already saved in the first device, the first device sends a second connection request to the second device based on the P2P connection information of the second device, but if the first device does not receive a connection response fed back by the second device based on the second connection request within a preset time length, the first device sends own P2P connection information to the second device.
S502, if the working channel of the second device comprises the P2P channel indicated by the P2P connection information of the first device, the second device sends a first connection request to the first device to request to establish a P2P connection with the first device based on the P2P connection information of the first device.

s603, the second device sends a first connection request to the first device to request to establish a P2P connection with the first device based on the P2P connection information of the first device;
s604, the second device sends the P2P connection information of the second device to the first device to trigger the first device to send a second connection request to the second device to request to establish P2P connection with the second device based on the P2P connection information of the second device.
In practical applications, the second device may not support the P2P channel indicated by the P2P connection information of the first device, for example, the first device indicates that the P2P connection is established using the 5G channel, but since the second device can only operate on the 2.4G channel, in this case, to avoid a connection failure, in this embodiment of the present application, if the second device cannot operate on the P2P channel indicated by the P2P connection information of the first device, the second device sends its P2P connection information to the first device, and triggers the first device to request to connect the second device, so as to improve connection stability.
In other embodiments, the sending, by the second device, the P2P connection information of the second device to the first device may include: if the second device and the first device have an established non-P2P connection link, the second device sending P2P connection information of the second device to the first device through the non-P2P connection link; if there is no established non-P2P connection link between the second device and the first device, the second device broadcasting its own P2P connection information; or, if there is no established non-P2P connection link between the second device and the first device, the second device establishes the non-P2P connection link with the first device, and the second device sends the P2P connection information of the second device to the first device through the established non-P2P connection link.
