Embodiment 1

[0041] Such as figure 1 As shown, it is a flowchart of the method for opening and changing WLAN services. The specific steps are as follows:

[0042] Step 101: The billing server (BOSS) receives a WLAN service activation request submitted by a terminal, where the WLAN service activation request includes a communication identifier and a terminal identifier.

[0043] When a terminal requests to enable WLAN services for itself or for other terminals, it needs to initiate registration with the BOSS. In the embodiment of the present invention, the communication identifier in the WLAN service activation request is the communication identifier of the terminal that initiated the request. If the terminal requests to activate the WLAN service for itself, the terminal identifier is the terminal of the terminal that initiated the WLAN service activation request. Identifier; if the terminal requests to open WLAN services for other terminals, the terminal identifier is the terminal identifier of...

Embodiment 2

[0066] After completing the opening and changing of the WLAN service, in the process of using the WLAN service, the second embodiment of the present invention provides a method for accessing the WLAN network to improve the security of the authentication process and prevent illegal users from using the WLAN service.

[0067] In this embodiment, it is assumed that after the WLAN service is activated and changed, the service status information corresponding to the activation of the WLAN service recorded in the authentication server is "offline".

[0068] Such as figure 2 As shown, it is a flowchart of a method for accessing a WLAN network provided by an embodiment of the present invention, and the specific steps are as follows:

[0069] Step 201: The first terminal sends an online service request to the authentication server.

[0070] When the second terminal needs to access the WLAN network, the first terminal bound to the second terminal during the service start-up process initiates an...

Embodiment 3

[0092] After using the method in the second embodiment of the present invention to access the WLAN network, the third embodiment of the present invention also provides a method for exiting the WLAN network, such as image 3 Shown is a flow chart of a method for exiting a WLAN network provided by Embodiment 3 of the present invention. In this embodiment, the authentication server and the service server may also be two independent devices, or may be integrated into one device. Similar to the second embodiment, if the authentication server and the service server are integrated into one server, the server can realize the functions of the authentication server and the service device in the following embodiment three, and the authentication server and service involved in the third embodiment The information exchange between servers will become the internal information transmission of the integrated server.

[0093] In the third embodiment of the present invention, the authentication ser...

Abstract

The invention provides a method, a system and an authentication server for being switched in and retreating from the wireless local area network (WLAN), which include storing corresponding relation among communication identification, terminal identification and business state information in advance in the authentication server, so that corresponding business state information can be updated to waiting for online according to the communication identification carried in online business request when the terminal demands to be on line. Therefore, when an AC conducts authentication on the terminal, the AC can search corresponding business state information according to the terminal identification, and only terminals with both the terminal identification and corresponding business state information meeting the requirements can be allowed to be switched in the WLAN network. Further, only terminals with terminal identification meeting the requirements are allowed to conduct off line operation when retreating from the WLAN network, so that generality of the WLAN business authentication is higher, no extra authentication link is required to be added, and authentication safety is higher.

Description

Technical field [0001] The present invention relates to the field of wireless communication, in particular to a method, system and authentication server for accessing and exiting a WLAN network. Background technique [0002] A wireless local area network (WLAN, Wireless LAN) is a technology that uses wireless technology to quickly access a local area network. Operators adopt a unified deployment method to build a wireless network environment to provide WLAN Internet services. [0003] WLAN services ensure the security of service execution through service authentication. Service authentication can adopt authentication methods such as client-based authentication, web page (WEB)-based authentication, and terminal-based network card (MAC) address authentication. Three authentication methods are explained. [0004] 1. The client-based authentication method is to install dedicated client software on the terminal. When the terminal needs to access the destination network via WLAN, the use...
