Wireless local area network WLAN access method, terminal, and server

A wireless local area network (WLAN) access method, comprising:

• receiving, by a server, a request from a terminal, wherein the request is for a list of available wireless access points and to query information about the available wireless access points, and wherein the request includes a parameter that specifies a type of a preset rule;
• obtaining, by the server, the list of available wireless access points including information about the available wireless access points according to the request from the terminal, wherein the information about the available wireless access points is related to the preset rule;
• sending, by the server, the list of available wireless access points to the terminal, wherein the list includes the information about the available wireless access points;
• acquiring, by the server, wireless connection authentication information from at least one WLAN service provider by:
• sending, by the server to the at least one WLAN service provider, a request for applying for connection authentication information;
• receiving, by the server, authentication information from the WLAN service provider;
• and
• storing, by the server, the received authentication information;
• sending, by the server, authentication information corresponding to a specific wireless access point to the terminal when an authentication information request of the specific wireless access point is received from the terminal, wherein the authentication information is used to connect the terminal to the specific wireless access point;
• receiving, from the terminal, permission usage information, wherein the permission usage information comprises consumed permission information and either a terminal identifier or a user identifier;
• and
• sending, to the terminal, unused permission information, wherein the unused permission information is obtained according to a permission allocated to the terminal and the permission usage information, and wherein the unused permission information indicates that the permission corresponding to the terminal has been exhausted.

A terminal, comprising:

• one or more memories comprising instructions;
• and
• one or more computer processors coupled to the one or more memories, wherein the instructions, when executed by the one or more computer processors, cause the terminal to be configured to:
• send a request to a server, wherein the request is for a list of available wireless access points to query information about the available wireless access points, and wherein the request includes a parameter that specifies a type of a preset rule;
• receive a list of available wireless access points from the server, wherein the list includes information about the available wireless access points that is related to the preset rule;
• determine a specific wireless access point from the list of available wireless access points according to the preset rule and based on the information about the available wireless access points in the list, wherein the preset rule is one or more of a signal strength, a charge rate, and available traffic;
• acquire authentication information of the specific wireless access point from the server;
• access the specific wireless access point corresponding to the authentication information using the authentication information;
• send permission usage information to the server, wherein the permission usage information comprises consumed permission information and either a terminal identifier or a user identifier;
• receive unused permission information from the server, wherein the unused permission information is obtained according to a permission allocated to the terminal and the permission usage information;
• and
• disconnect the terminal from the specific wireless access point when the unused permission information indicates that the permission corresponding to the terminal has been exhausted.
