Network connection method, application authentication server, terminal and router

A network connection method, comprising:

• broadcasting a network connection request, so that a router receiving the network connection request returns first router identification information;
• receiving the first router identification information, and acquiring a corresponding first application account;
• submitting the first application account and the first router identification information to an application authentication server, so that the application authentication server authenticates, according to the first application account and the first router identification information, permission to connect to a network through the router, and after determining that the permission authentication succeeds, the application authentication server returns authentication information of connecting to the network through the router;
• and
• receiving the authentication information, and connecting to the network through the router according to the authentication information.

An application authentication server, comprising:

• an acquiring module, configured to acquire a first application account corresponding to a terminal and first router identification information received by the terminal, the first router identification information being sent by a router corresponding to the first router identification information;
• a determining module, configured to determine, according to the first application account and the first router identification information, whether the terminal has permission to connect to a network through the router;
• and
• a returning module, configured to return, to the terminal when it is determined that the terminal has permission to connect to the network through the router, authentication information of connecting to the network through the router, so that the terminal connects to the network through the router according to the authentication information after receiving the authentication information.

A terminal, comprising:

• a broadcast module, configured to broadcast a network connection request, so that a router receiving the network connection request returns first router identification information;
• a first receiving module, configured to receive the first router identification information;
• an acquiring module, configured to acquire a corresponding first application account;
• a submission module, configured to submit the first application account and the first router identification information to an application authentication server, so that the application authentication server authenticates, according to the first application account and the first router identification information, permission to connect to a network through the router, and after determining that the permission authentication succeeds, the application authentication server returns authentication information of connecting to the network through the router;
• and
• a second receiving module, configured to receive the authentication information;
• and
• a connection module, configured to connect to the network through the router according to the authentication information.
