Method and system of using gateway device to provide differentiated services in wireless network

Abstract

The invention discloses a method and system of using a gateway device to provide differentiated services in a wireless network. The method comprises the following steps: an access controller (AC) obtains the correspondence of the MAC address and SSID in a message sent by a terminal and sends the correspondence to a transfer device; the transfer device receives the correspondence in the message sent by the terminal and obtains the correspondence of the IP address and SSID of the terminal according to the correspondence of MAC address and SSID obtained from the AC; and the gateway device storesthe corresponding correspondence of the IP address and SSID of the terminal sent by the transfer device, searches the IP address carried by the message sent by the terminal, searches the corresponding SSID according to the searched IP address, obtains the service type corresponding to the terminal according to the preset correspondence of SSID and service type and provides differentiated services. By using the method and device of the invention, the gateway device in WLAN environment can provides differentiated services for the terminal.

Description

technical field [0001] The present invention relates to the field of communications, in particular to a method and system for gateway equipment in a wireless network to provide differentiated services. Background technique [0002] With the development of wireless networks, especially when major operators begin to deploy their own hotspots, there are more and more cases of accessing networks through WLAN (Wireless Local Area Network, wireless local area network). Users accessing the network through WLANs have requirements for differentiated services, for example, some users require encryption services, and some users require larger bandwidth or higher priority. In the traditional fixed network, the location of the user equipment accessing the network is relatively fixed, and its IP address does not change much. These differentiated services are generally realized by distinguishing the user's IP address. However, in WLAN applications, user equipment may move at any time, and...

Problems solved by technology

[0004] When the application environment changes to a WLAN environment, such as figure 2 As shown, one wireless AP cannot cover all areas, and the user PC can move between several APs and access the network through different APs. At this time, the IP address of the fixed PC cannot be realized basically, and the gateway differentiates based on the IP address. Action rules can no longer be used
