In order to make the aforementioned objects, features and advantages of the embodiments of the present invention more comprehensible, specific embodiments accompanied with figures are described in detail below.
Referring to fig. 1, a flowchart of a wireless connection scanning method in an embodiment of the present invention is shown. The method specifically comprises the following steps:
and step 11, in the scanning process of the target wireless connection, receiving link information sent by the first device based on the target wireless connection.
In a specific implementation, when a wireless connection is established between user equipments, scanning and discovery processes need to be performed first to start a user equipment of a subsequent connection process, and in a scanning process of a target wireless connection, link information sent by a first device based on the target wireless connection may be received.
In a specific implementation, the link information may include target wireless connection sub-device information of the first device and other wireless connection sub-device information of the first device, where the target wireless connection sub-device information is used to establish a target wireless connection between the user devices, and the other wireless connection sub-device information is used to establish other wireless connections between the user devices.
In an implementation, the target wireless connection sub-device information may include a device name of the target wireless connection sub-device, and may also include one or more of a Media Access Control (MAC) Address, a wireless capability, an operating frequency band, and the like. The specific content included in the target wireless connection sub-device information can be set according to actual requirements. The other wireless connection sub-device information may include device names of the other wireless connection sub-devices, and may also include one or more of MAC addresses, wireless capabilities, operating frequency bands, and the like.
In an embodiment of the present invention, the target wireless connection is WIFI, and the other wireless connections may include bluetooth, or other wireless connections that can be connected only by performing a scanning and discovery process when establishing a connection, which is not illustrated herein.
In another embodiment of the present invention, the target wireless connection is bluetooth, and the other wireless connections may include WIFI or other wireless connections that need to be scanned and discovered first to be connected when establishing a connection, which is not illustrated herein.
In a specific implementation, the target wireless connection sub-device and the other wireless connection sub-devices may be located in the same wireless communication chip of the first device, or may be located in different wireless communication chips. When the target wireless connection sub-device and other wireless connection sub-devices are located in different wireless communication chips, information interaction can be carried out among the different wireless communication chips.
And step 12, obtaining the target wireless connection sub-device information of the first device and other wireless connection sub-device information of the first device from the link information.
In a specific implementation, after receiving the link information, the target wireless connection sub-device information and the other wireless connection sub-device information of the first device may be obtained from the first link information.
According to the scheme, in the target wireless connection scanning process, the received link information not only includes the target wireless connection sub-device information, but also includes other wireless connection sub-device information of the first device, and the other wireless connection sub-device information is used for establishing other wireless connections. The target wireless connection sub-device information and the other wireless connection sub-device information of the first device can be obtained together from the link information sent by the first device based on the target wireless connection, so that the target wireless connection sub-device information and the other wireless connection sub-device information of the first device can be obtained together in the process of completing the target wireless connection scanning, and the other wireless connection sub-device information does not need to be obtained through other wireless connection scanning like the prior art. Therefore, compared with the prior art that the same type of wireless connection is completed, the wireless scanning method provided by the embodiment of the invention can reduce the scanning time. Wherein the target wireless connection and the other wireless connections are different wireless connections, e.g. one is bluetooth and the other is WIFI.
In a specific implementation, the link information may be of various types, for example, the link information includes a scan request response frame, that is, the link information is carried in the scan request response frame. For another example, when the target wireless connection is WIFI, the link information includes a beacon management frame, that is, the link information is carried in the beacon management frame. The existence mode or carrying mode of the link information is related to the type of the target wireless connection.
Referring to fig. 2, a flow chart of another wireless connection scanning method in an embodiment of the invention is shown. On the basis of the wireless connection scanning method shown in fig. 2 and the wireless connection scanning method shown in fig. 1, when the link information includes a scan request response frame, the wireless connection scanning method may further include the following step 21 before performing step 11.
In a specific implementation, the target wireless connection scanning request may include target wireless connection sub-device information of the second device and other wireless connection sub-device information of the second device. When the first device receives the target wireless connection scanning request, the link information is fed back to the second device, wherein the information specifically included in the fed back link information can be determined according to the information carried in the target wireless connection scanning request. When the first device has other corresponding wireless connections, the first device carries the information of the target wireless connection sub-device and simultaneously carries the information of the other wireless connection sub-devices in the link information fed back to the second device.
For example, when the target wireless connection is WIFI, the WIFI scanning request includes WIFI sub-device information and bluetooth sub-device information of the second device, and after the first device receives the WIFI scanning request, according to the bluetooth sub-device information in the WIFI scanning request, the link information carries the WIFI sub-device information and also carries the bluetooth sub-device information.
If the target wireless connection is bluetooth, the bluetooth scanning request includes bluetooth sub-device information of the second device and WIFI sub-device information of the second device, and after the first device receives the bluetooth scanning request, the link information carries the bluetooth sub-device information and also carries the WIFI sub-device information due to the WIFI sub-device information in the bluetooth scanning request.
In an embodiment of the present invention, the target wireless connection is WIFI, and the link information is a beacon management frame. Specifically, a scanning process needs to be started before two WIFI devices are connected, one WIFI device serves as a WIFI wireless Access Point (AP) role, the other WIFI device serves as a Station (STA) role, and the AP periodically broadcasts a Beacon management Frame (Beacon Frame), wherein the Beacon Frame carries WIFI sub-device information in the AP, such as a wireless AP node name (ssid), wireless capability (capability), and the like. The STA also actively initiates a WIFI scan request (probe request), where the WIFI scan request includes WIFI sub-device information and BT sub-device information. After receiving the scan request, the AP carries WIFI sub-device information (SSID, capability, etc.) and BT sub-device information (e.g., one or more of BT sub-device name, MAC address, etc.) of the AP in a request response frame (probe response), and replies the request response frame to the STA.
For a user equipment with a WIFI function, which may be a hotspot or a router, the AP periodically broadcasts a beacon management frame to carry WIFI sub-equipment information and other supported wireless connection sub-equipment information (e.g., BT sub-equipment information). After the STA receives the beacon management frame regularly broadcast by the AP, the WIFI sub-device information and the BT sub-device information of the AP can be acquired, so that a plurality of wireless connection sub-devices can be discovered simultaneously in one wireless connection scanning process.

In a specific implementation, the link information may include: target wireless connection sub-device information of a first device and other wireless connection sub-device information of the first device. And after receiving the link information, the second device acquires the target wireless connection sub-device information of the first device and other wireless connection sub-device information of the first device from the link information.
In an embodiment of the present invention, the target wireless connection is WIFI, and the other wireless connections include wireless connections such as bluetooth.
In another embodiment of the present invention, the target wireless connection is bluetooth, and the other wireless connections include wireless connections such as WIFI.
In a specific implementation, when the target wireless connection is WIFI, the link information sent based on the target wireless connection may include a beacon management frame, that is, the link information is carried in the beacon management frame. The first device may send out the beacon management frame by means of periodic broadcast.
In an implementation, the wireless connection scanning method may further include the following steps 31 and 32.
In a specific implementation, the target wireless connection scanning request is sent by a second device, and the target wireless connection scanning request includes target wireless connection sub-device information of the second device and other wireless connection sub-device information of the second device.
And step 32, generating the link information according to the target wireless connection scanning request.
In a specific implementation, according to the information of the other wireless connection sub-devices in the target wireless connection scanning request, when the own device has the corresponding information of the other wireless connection sub-devices, the information of the other wireless connection sub-devices is acquired.
