METHODS AND DEVICES FOR QUERYING AUTHENTICATION INFORMATION OF A WIRELESS ACCESS POINT
The present application provides a method and a device for querying authentication information of a wireless access point. The present disclosure enables acquisition of a determined target wireless access point according to a scan list of wireless access points transmitted by a user, and further acquires authentication information of the corresponding wireless access point and stores the same to a user mobile equipment. When establishing wireless access, authentication information of the corresponding wireless access point is first queried in the user mobile equipment. A query request is only submitted to a server if the mobile equipment does not have the corresponding authentication information. The present application reduces the number of interaction with the server to reduce the load of the server and save data traffic of the user mobile equipment. The present disclosure also guarantees a timely update of authentication information of wireless access points on the user mobile equipment.
1 . A method for querying authentication information of a wireless access point at a server, the method comprising:
acquiring a query request transmitted by a user equipment and determining a target wireless access point according to the query request;
determining wireless access points associated with the target wireless access point according to an association rule;
acquiring authentication information of the target wireless access point and its associated wireless access points; and
transmitting the authentication information to the user equipment.
2 . The method as recited in claim 1 , wherein the acquiring of a query request transmitted by a user equipment and determining a target wireless access point according to the query request, comprising:
acquiring a query request transmitted by a user equipment, wherein the query request includes a scan list acquired by the user equipment and the scan list contains identifier information of the wireless access points scanned by the user equipment; and
determining a wireless access point contained in the scan list as the target wireless access point.
3 . The method as recited in claim 1 , the method further comprising:
acquiring a scan list transmitted by a user equipment, wherein the scan list contains identifier information of the wireless access points scanned by the user equipment;
wherein the association rule comprises:
wireless access points associated with a wireless access point comprise other wireless access points in one or more scan lists containing the wireless access point.
4 . The method as recited in claim 1 , wherein the authentication information comprises a hotspot password and an identifier indicating whether there is a hotspot password.
5 . A method for querying authentication information of a wireless access point at a user equipment, the method comprising:
determining a target wireless access point for query;
searching authentication information of the target wireless access point in an authentication information buffer, wherein the authentication information buffer is used to store authentication information of wireless access points acquired from a server;
reading the authentication information of the target wireless access point when the authentication information of the target wireless access point exists in the authentication information buffer;
transmitting a query request to the server when the authentication information of the target wireless access point does not exist in the authentication information buffer; and
receiving and storing the authentication information of the target wireless access point and its associated wireless access points transmitted and determined based on the query request by the server.
6 . The method as recited in claim 5 , wherein the step of determining a target wireless access point for query, comprising:
acquiring a scan list obtained via channel scanning, wherein the scan list contains identifier information of the wireless access points scanned by the user equipment; and
determining a wireless access point contained in the scan list as the target wireless access point.
7 . The method as recited in claim 5 , wherein the authentication information includes a hotspot password and an identifier indicating whether there is a hotspot password.
8 . The method as recited in claim 5 , wherein the method further comprising:
deleting authentication information in the authentication information buffer in chronological order after content capacity of the authentication information buffer exceeds a preset upper limit.
9 . The method as recited in claim 5 , wherein the method further comprising:
after failing to connect to a corresponding wireless access point using authentication information in the authentication information buffer, deleting the authentication information from the authentication information buffer.
10 . A device for querying authentication information of a wireless access point at a server, the device including a memory for storing computer program instructions and a processor for executing program instructions, wherein the computer program instructions, when executed by the processor, cause the device to:
acquire a query request transmitted by a user equipment and determining a target wireless access point according to the query request;
determine wireless access points associated with the target wireless access point according to an association rule;
acquire authentication information of the target wireless access point and its associated wireless access points; and
transmit the authentication information to the user equipment.
