Enter to after access network, the network name according to the access network finds and accesses most suitable AC.For example, for network name
WNAME_EDU, operator is that the AC of network name configuration is the most abundant AC of education network interface bandwidth, so, WLAN user
Terminal will be linked into the most abundant AC of education network interface bandwidth；For network name WNAME_GAME, operator is the network name
The AC of configuration is called the AC of the AC of region where game base or neighbouring game bases, and so, WLAN user terminal will be linked into
The AC of the AC of region where game base or neighbouring game bases；
Wherein, name server can be integrated in domain name system (DNS, Domain Name System), integration mode
To add mapping table in the dns server, it is corresponding with AC addresses that the list item in the mapping table is network name
Relation；Additionally, name server is only opened to believable AP, for believable AP inquiry AC addresses, refuse the AP inquiries of untrusted
AC addresses, therefore, name server needs, when AP inquires about AC addresses, to verify the IP address of the AP；
After name server receives the inquiry request message of AP transmissions, first, according to the credible AP's being locally pre-configured with
Whether IP address storehouse, the IP address to the AP verifies there is the IP address of the AP in the IP address storehouse for judging credible AP, if
There is the IP address of the AP, be then verified, network name and local preservation of the name server in inquiry request message
Network name and AC addresses corresponding relation, search AC addresses corresponding with the network name, the AC addresses that will be found pass through
Query response message is sent to AP；If the not no IP address of the AP, authentication failed, name server refusal is AP inquiries
AC addresses, inquiry failed message is sent to AP.
Step 305, AP reflects according to the network name selected and the AC addresses for inquiring, establishment network name with AC addresses
Relation is penetrated, and sets up itself and the data tunnel between the AC addresses；
Specifically, AP receives name server by behind the AC addresses that query response message is returned, according to the AC addresses, building
Itself and the data tunnel WNAME_TUNNEL between the AC addresses are found, as long as shown in figure 4, AP receives one from name server
Individual AC addresses, you can set up data tunnel with the AC addresses, after multiple AC addresses are received, an AP can ACs different from multiple
Between set up data tunnel, it is convenient after AP user data is sent to different AC；After setting up data tunnel, AP is also needed to
The mapping relations of the AC addresses and network name for receiving are locallyd create, in this way, after WLAN user terminal is linked into certain access network,
The user data that WLAN user terminal sends, will be sent to the AC addresses corresponding to the network name of the access network by AP, by
Corresponding AC carries out the treatment of user data.
The method that the present invention also provides segmentation flow in a kind of WLAN, the method includes：WLAN user terminal root
According to the data service of itself network name is selected in the network name that AP is broadcasted.
Specifically, when WLAN user terminal searching network, WLAN user terminal can receive the broadcast that each AP sends
Message, at least two network names are obtained in the master data frame carried from the broadcast message；WLAN user terminal is according to itself
Data service in the network name that AP is broadcasted independently selection one network name, after selecting network name, WLAN user end
The connection that end is set up between access network corresponding with the network name, in this way, the AP in access system is it is known that WLAN
The network name that user terminal is selected；
For example, the data service of WLAN user terminal is related to education network, then the network name of WLAN user terminal selection is
WNAME_EDU；The data service of WLAN user terminal is related to online game, then the network name of WLAN user terminal is WNAME_
