Method for implementing WiFi communication, user equipment and wireless routing device

A method for implementing wireless fidelity (WiFi) communication comprising:

• accessing, by a user equipment, a mobile communication network by using a wireless routing device, wherein the mobile communication network is different from a WiFi communication network;
• detecting, by the user equipment, a signaling message broadcast by the WiFi communication network;
• initiating, by the user equipment, an access request to the WiFi communication network;
• receiving, by the user equipment, an authentication request from the WiFi communication network, wherein the authentication request comprises an authentication request parameter for the WiFi communication network to authenticate the user equipment;
• sending, by the user equipment, a request to the wireless routing device, wherein the request comprises the authentication request parameter;
• receiving, by the user equipment, response sent from the wireless routing device, wherein the response comprises an expected authentication result, and wherein the wireless routing device obtains the expected authentication result from a subscriber identity module in the wireless routing device;
• and
• sending, by the user equipment, the expected authentication result to the WiFi communication network such that the WiFi communication network authenticates the user equipment according to the expected authentication result;
• and
• accessing, by the user equipment, the WiFi communication network.

A wireless routing device comprising:

• a receiving module configured to receive a request sent by a user equipment, wherein the request comprises an authentication request parameter for a wireless fidelity (WiFi) communication network to authenticate the user equipment, wherein the wireless routing device accesses a mobile communication network, wherein the mobile communication network is different from the WiFi communication network such that the user equipment accesses the mobile communication network by using the wireless routing device;
• a sending module configured to send the authentication request parameter to a subscriber identity module and send a response to the request to the user equipment, wherein the response comprises an expected authentication result, wherein the expected authentication result is returned to the WiFi communication network by the user equipment, and wherein the subscriber identity module is in the wireless routing device;
• and
• an obtaining module configured to obtain the expected authentication result from the subscriber identity module, wherein the expected authentication result is generated by the subscriber identity module according to the authentication request parameter and an authentication key saved in the subscriber identity module.

A user equipment comprising:

• a receiving module configured to receive an authentication request from a wireless fidelity (WiFi) communication network after a signaling message broadcast b the WiFi communication network is detected by the user equipment and an access request is initiated to the WiFi communication network by the user equipment, and receive, a response sent from a wireless routing device, wherein the user equipment accesses a mobile communication network by using the wireless routing device, wherein the mobile communication network is different from the WiFi communication network, wherein the authentication request comprises an authentication request parameter for the WiFi communication network to authenticate the user equipment, wherein the response comprises an expected authentication result;
• and
• a sending module configured to send a request to the wireless routing device and send the expected authentication result to the WiFi communication network such that the WiFi communication network authenticates the user equipment according to the expected authentication result, wherein the request comprises the authentication request parameter, and wherein the expected authentication result is used for the user equipment to access the WiFi communication network, and wherein the wireless routing device obtains the expected authentication result from a subscriber identity module in the wireless routing device.
