Problems solved by technology

However, the authentication delay of complex authentication methods is very large, which is not feasible for real-time applications. Moreover, real-time applications focus on real-time rather than security. Therefore, in the case of no distinction between data applications and real-time applications ,

Embodiment Construction

[0053] The specific embodiment of the present invention is described below in conjunction with accompanying drawing:

[0054] In this embodiment, multiple virtual APs are configured on a single physical AP, and virtual APs can be implemented by creating multiple virtual interfaces on the AP, such as Figure 5 shown. Virtual interfaces are created and destroyed by the tool wlanconfig. Set an SSID for each virtual interface, and virtual interfaces with the same SSID on multiple APs form a virtual WLAN, so that one physical WLAN can be virtualized into multiple WLANs. For the same AP, it can serve multiple SSIDs, and users only need to select different SSIDs according to different services to connect to the corresponding virtual AP.

[0055] In addition, the corresponding relationship information between the service category and the authentication method is also configured on the AP. The corresponding relationship information can be the corresponding relationship between the SS...

Abstract

The invention relates to a method and a system for improving the quality of service (QoS) of a real-time service in a wireless local area network based on service differentiation. The method comprises the following steps of: establishing a plurality of virtual contacts at one access point (AP) and allocating different service set identifiers (SSID) to each virtual contact, wherein the SSIDs correspond to service types and corresponding relation information of the service types and authentication modes is also allocated at the AP; when a mobile terminal is associated/reassociated to the AP, acquiring each SSID allocated by the AP from the AP and carrying the SSID corresponding to the service type currently applied by the mobile terminal in an authentication request; selecting a corresponding authentication mode for authentication by the AP according to the service type corresponding to the received SSID, wherein the authentication of the real-time service is quicker than that of a non-real-time service. The method preferentially ensures the QoS of the real-time service based on service type differentiation.

Description

technical field [0001] The invention belongs to wireless local area network (WLAN) technology, and mainly relates to a method for improving real-time business service quality (QoS) in wireless local area network. Background technique [0002] First define the acronyms used in this manual: [0003] WLAN (Wireless Local Area Network): wireless local area network; [0004] AP (Access Point): base station, wireless base station, access point, providing wireless network access services for mobile terminals; [0005] Station: mobile terminal, a terminal user in WLAN, accesses WLAN through AP, and accesses the network; [0006] SSID (Service Set ID): Service Set ID, which is the network name of the WLAN, and SSID information needs to be exchanged during the association process between the Station and the AP; [0007] QoS (Quality of Service): quality of service, in the present invention, mainly pay attention to this QoS index of " delay "; [0008] EDCA (Enhanced Distributed Ch...
