Problems solved by technology

[0004] However, with the continuous development of wireless communication technology, the performance of the AC has gradually been unable to meet the user data forwarding under each AP. Therefore, the local forwarding technology came into being, that is, the AP and STA are still managed by the AC through the CAPWAP tunnel, but the STA's The data is forwarded through the AP connected to it, and no longer centrally forwarded by the AC through the CAPWAP tunnel
Since the data no longer passes through the AC, the user's Portal authentication cannot be realized through the existing authentication architecture, and an additional Portal server needs to be added at a place reachable to the second layer of the AP, such as figure 2 shown
In this way, in the case of using AP local forwarding, the existing network architecture cannot be directly used, and the number of devices in the network has to be increased, thereby increasing the cost

Embodiment 1

[0038] Figure 4 The detailed method flow chart that provides for the first embodiment of the present invention, in this flow process still uses such as figure 1 The existing authentication architecture shown is used to realize the authentication in the case of AP local forwarding. In this method, the local forwarding function is disabled before configuring the STA authentication on the AP, and the downlink local forwarding function is enabled by default. Such as Figure 4 As shown, the method may include the following steps:

[0039] Step 401: After the STA is connected to the AP, it sends a Dynamic Host Configuration Protocol (DHCP) request message.

[0040] After the STA initially connects to the AP, it will find that the STA does not have any IP address settings, so it will send a DHCP request message carrying the MAC address of the STA. The source address of the DHCP request message will be 0.0.0.0, while The destination address is 255.255.255.255.

[0041] Step 402: ...

Embodiment 2

[0072] Figure 7 The detailed method flow chart that provides for the second embodiment of the present invention, also, still use such as in this flow process figure 1 The existing authentication architecture shown in Figure 1 is used to realize the authentication in the case of AP local forwarding, such as Figure 7 As shown, the method may include the following steps:

[0073] Steps 701-707 are the same as steps 401-407 and will not be repeated here.

[0074] In this embodiment, the AP initially disables the uplink and downlink local forwarding functions of the STA by default.

[0075] Step 708: After receiving the authentication request, the Portal server authenticates the user, and sends an authentication success response to the STA after the authentication is passed.

[0076] The destination IP address of the authentication success response is the IP address of the STA.

[0077] In this embodiment, since the AP initially disables the downlink local forwarding function...

Abstract

The invention provides a method, a system and a device for authenticating a portal in a wireless network. The method comprises the following steps: after receiving an authenticating request of a mobile terminal (STA) by a wireless access point (AP), transmitting the authenticating request to an accessing controller (AC) through the control of the wireless accessing point and a supply protocol (CAPWAP) tunnel, and forwarding the authenticating request to a portal server by the AC; after the AC successfully authenticates the STA by the Portal server, transmitting configuration information to indicate the AP to start a local forwarding function to the STA through the CAPWAP tunnel by the AC; and after learning a condition that the STA quits the authentication, transmitting configuration information to indicate the AP to close the local retransmission function to the STA through the CAPWAP tunnel. The invention is capable of using a prior network authentication framework to perform a Portal authentication under the condition of an AP local retransmission without extra increasing authenticating apparatuses, thereby saving the networking cost.

Description

technical field [0001] The invention relates to the technical field of wireless local area network (WLAN), in particular to an entrance authentication method, system and device in a wireless network. Background technique [0002] In the current wireless network, the centralized wireless local area network is more and more widely used because of its advantages of strong manageability and suitability for large-scale deployment. In a centralized wireless local area network, the AC and AP can be connected through a proprietary protocol tunnel, commonly used is the Wireless Access Point Control and Provisioning (CAPWAP, Controlling and Provisioning of Wireless Access Point) protocol, through the CAPWAP tunnel can be Data transmission and configuration management between APs and ACs. [0003] In a traditional centralized WLAN, the portal (Portal) authentication is sent to the Portal server through the AC. After the user's Portal authentication is passed, the AC forwards the data ...
