Abstract

A method for accessing a wireless access point is provided. The method includes: receiving access information of the wireless access point broadcasted by a preset device, the access information including a Basic Service Set Identifier (BSSID) and an access password of the wireless access point, and the preset device having successfully accessed the wireless access point; unicasting device discovery information according to the BSSID, the device discovery information including the BSSID; receiving feedback information sent by the wireless access point, the feedback information including a Service Set Identifier (SSID) of the wireless access point; and accessing the wireless access point according to the SSID in the feedback information and the access password.

Claims

1. A method for accessing a wireless access point, comprising:

receiving, by a smart device, access information of the wireless access point broadcasted by a preset device, the access information including a Basic Service Set Identifier (BSSID) and an access password of the wireless access point, and the preset device having successfully accessed the wireless access point;

unicasting, by the smart device, device discovery information according to the BSSID, the device discovery information including the BSSID;

receiving, by the smart device, feedback information sent by the wireless access point, the feedback information including a Service Set Identifier (SSID) of the wireless access point; and

accessing, by the smart device, the wireless access point according to the SSID in the feedback information and the access password,

wherein the SSID of the wireless access point is a first SSID, and the access information broadcasted by the preset device further includes a second SSID, the method further comprising;

before unicasting the device discovery information according to the BSSID, detecting whether the second SSID in the access information includes a preset character, the preset character having a plurality of coding formats; and

when the preset character is included in the second SSID, performing the unicasting of the device discovery information according to the BSSID.

2. The method of claim 1, wherein the device discovery information comprises a probe request, the probe request including the BSSID.

3. The method of claim 2, wherein the feedback information sent by the wireless access point comprises a probe response sent by the wireless access point.

4. The method of claim 1, further comprising:

when the preset character is not included in the second SSID, accessing the wireless access point according to the second SSID broadcasted by the preset device and the access password.

5. The method of claim 1, wherein the preset device is a mobile phone, and the wireless access point is a wireless router.

6. An apparatus for accessing a wireless access point, comprising:

a processor; and

a memory for storing instructions executable by the processor;

wherein the processor is configured to execute the instructions to cause the apparatus to;

receive access information of the wireless access point broadcasted by a preset device, the access information including a Basic Service Set Identifier (BSSID) and an access password of the wireless access point, and the preset device having successfully accessed the wireless access point;

unicast device discovery information according to the BSSID, the device discovery information including the BSSID;

receive feedback information sent by the wireless access point, the feedback information including a Service Set Identifier (SSID) of the wireless access point; and

access the wireless access point according to the SSID in the feedback information and the access password,

wherein the SSID of the wireless access point is a first SSID, and the access information broadcasted by the preset device further includes a second SSID, the processor further being configured to;

before unicasting the device discovery information according to the BSSID, detect whether the second SSID in the access information includes a preset character, the preset character having a plurality of coding formats; and

when the preset character is included in the second SSID, unicast the device discovery information according to the BSSID.

7. The apparatus of claim 6, wherein the device discovery information comprises a probe request, the probe request including the BSSID.

8. The apparatus of claim 7, wherein the feedback information sent by the wireless access point comprises a probe response sent by the wireless access point.

9. The apparatus of claim 6, wherein the processor is further configured to:

when the preset character is not included in the second SSID, access the wireless access point according to the second SSID broadcasted by the preset device and the access password.

10. The apparatus of claim 6, wherein the preset device is a mobile phone, and the wireless access point is a wireless router.
