Embodiment Construction

[0029] After the mobile station (MT) establishes 802.11 association with the network side of the wireless local area network, the present invention uses a logical network identifier to distinguish different logical networks on the same SSID.

[0030]According to actual application requirements, the mobile station can establish 802.11 association with the network side in the following two ways:

[0031] (1) Same as the prior art, rely on matching SSID to establish 802.11 association, that is, different physical APs are distinguished by SSID. In this way, if the SSID of the mobile station does not match the SSID of the AP, the mobile station cannot access the AP.

[0032] (2) Establish 802.11 associations without relying on matching SSIDs, that is, do not use SSIDs to distinguish physical APs. In this way, even if the SSID of the mobile station does not match the SSID of the AP, it can still access the AP. This is because the service set identifier (SSID) is transmitted in cle...

Abstract

The invention relates to a method for supporting several logic networks in the wireless local network, which can solve the problems of high complexity and wireless resource consumption when using WLAN network to support several logic network. When the mobile station of wireless local network is connected with 802.11 relationship to the network, the network attains the logic network label of logic network of said mobile station, and according to said logic network label to access into relative logic network. the invention also discloses a logic access controller, which comprises a 802.11 relate unit, a logic network select unit and a logic gateway relate unit.

Description

technical field [0001] The present invention relates to a wireless local area network, in particular to a method and device for supporting multiple logical networks in a wireless local area network (WLAN). Background technique [0002] There are many types of WLAN technologies, including Hiperlan of European ETSI, HiSWAN of Japan and IEEE 802.11 formulated by IEEE of the United States. At present, IEEE 802.11 has become the de facto standard and has been widely supported and applied, including enterprise wireless networking applications and public hotspot operation applications. Since WLAN mainly uses non-regulated frequency bands, simultaneous deployment of WLAN networks by multiple operators at the same location is likely to cause interference and eventually lead to service quality degradation or even network unavailability. Therefore, there is a demand for WLAN network facility sharing, such as multiple WLAN access service providers share the public hotspot WLAN infrastr...
