acquiring access information corresponding to the wireless access point returned by the network device based on the access request, and displaying accessible prompt information on a wireless access point list of native system of the user equipment;

establishing, based on the access information of the wireless access point, a wireless connection between the user equipment and the wireless access point;

detecting a network connection state of the connected wireless access point;

if a wireless connection between the user equipment and the wireless access point fails, acquiring the network connection failure information; and

reselecting, based on the network connection failure information, a wireless access point with the accessible prompt information for connection.

2. The method for establishing a wireless connection according to claim 1 , further comprising:

presenting advertisement information corresponding to the wireless access point on the user equipment.

3. The method for establishing a wireless connection according to claim 2 , wherein the step of presenting advertisement information corresponding to the wireless access point on the user equipment specifically comprises:

detecting whether a trigger condition for presenting the advertisement information is satisfied; and

when the trigger condition is satisfied, presenting the advertisement information corresponding to the wireless access point on the user equipment,

wherein the trigger condition comprises:

acquiring a wireless access point that the user equipment selects to connect to; and

acquiring, based on SSID information of the wireless access point, advertisement information corresponding to the wireless access point.

4. The method for establishing a wireless connection according to claim 1 , further comprising:

detecting a security state of the acquired wireless access point.

5. The method for establishing a wireless connection according to claim 4 , wherein the step of detecting a security state of the acquired wireless access point comprises:

receiving a wireless signal from the wireless access point near the user equipment;

acquiring the SSID information of the wireless access point;

sending, to the network device, a security state detection request for the wireless access point, wherein the detection request comprises the SSID information; and

acquiring security state detection information of the wireless access point.

6. The method for establishing a wireless connection according to claim 1 , further comprising:

detecting a connection state of the selected wireless access point with the accessible prompt information at the user equipment;

if the wireless access point with the accessible prompt information is in a first-time-connection state at the user equipment, authenticating the access information of the wireless access point; and

allowing the user equipment to establish a connection with the wireless access point, after the authentication is passed.

7. The method for establishing a wireless connection according to claim 6 , further comprising:

if a connection record of the wireless access point with the accessible prompt information has been stored at the user equipment, the user equipment directly establishing a wireless connection with the wireless access point.

8. A method for establishing a wireless connection at a network device end, comprising:

receiving an access request for a wireless access point sent by a user equipment;

determining, based on the access request from the user equipment, access information corresponding to the wireless access point;

sending the access information of the wireless access point to the user equipment;

receiving a detection request for a security state of the wireless access point sent by the user equipment;

determining, based on the detection request from the user equipment, one or more security states of wireless access points; and

sending security state detection information of the wireless access points to the user equipment.

9. The method for establishing a wireless connection to claim 8 , wherein the step of determining the access information comprises:

determining, based on the access request from the user equipment, access information and point of interest POI information corresponding to the wireless access point; and

wherein the step of sending the access information comprises:

sending the access information and the POI information of the wireless access point to the user equipment.

10. A method for establishing a wireless connection at a user equipment end, comprising:

acquiring a wireless access point near the user equipment;

sending, to a network device, an access request for the wireless access point, wherein the access request comprises SSID information of the wireless access point;

acquiring access information and POI information corresponding to the wireless access point returned by the network device based on the access request, and displaying accessible prompt information and the POI information on a wireless access point list of the user equipment, wherein the wireless access point list comprises the wireless access point list of a native system of the user equipment or the wireless access point list of a third-party application of the user equipment;

establishing, based on the access information and the POI information of the wireless access point, a wireless connection between the user equipment and the wireless access point;

detecting a network connection state of the connected wireless access point;

if a wireless connection between the user equipment and the wireless access point fails, acquiring network connection failure information; and

reselecting, based on the network connection failure information, a wireless access point with the accessible prompt information for connection.
