There are two types of situations for the bandwidth tool of terminal distribution：（1）, the first situation be access point（AP, Access Point）Not limiting terminal
The bandwidth of occupancy, the bandwidth that terminal occupies depend on AP performances and the concurrent terminal access situations of follow-up AP, the occupied band of terminal
Width is dynamic change, can not ensure bandwidth usage；（2）The second situation is the uplink and downlink band of advance static prescribed terminal
The wide upper limit, such as uplink and downlink 2M, bandwidth workable for terminal are up to 2Mbps.
For the first above-mentioned situation, there are the following problems：First, the WLAN hot spot utilization of resources is unreasonable, single terminal
May occupy the massive band width of AP, for example, terminal carry out it is point-to-point（P2P, Point to Point）It may be occupied during download big
The bandwidth of amount, so as to cause WLAN hot spot or the super busy phenomenon of WLA N AP bursts；Second, when new user accesses above-mentioned super busy AP
Afterwards, since WLAN is using simple wave carrier conflict detection technique, the bandwidth that accessed terminal occupies will be limited, also with accessed terminal
The bandwidth of AP is averraged, the user of such accessed terminal just can substantially perceive the decline of access rate, cause to user
The decline of the service quality of access.
As it can be seen that the first above-mentioned situation deposits the problem of bandwidth that can not dynamically efficiently control terminal occupancy in a wlan.
For above-mentioned the second situation, there are the following problems：First, after wide to tape above and below terminal limitation, even if AP
Bandwidth resources are sufficient, but terminal can only also use the bandwidth of static configuration, the problem of causing bandwidth usage insufficient；Second, i.e.,
When making terminal that there is preferable access capability, the bandwidth of static configuration can only be also used, so leads to not make full use of terminal
Access capability or in the access capability deficiency of terminal, using the bandwidth of static configuration, may result in the wave of bandwidth resources
Take namely the access capability of the bandwidth of static configuration and terminal reality mismatches.
As it can be seen that above-mentioned the second situation asking there is also the bandwidth that terminal occupancy can not be dynamically efficiently controlled in WLAN
Topic.
To sum up, the problem of bandwidth of terminal occupancy can not be dynamically efficiently controlled in existing WLAN.

It should；
According to the clooating sequence of user gradation, dispatch successively and the user identifier in the corresponding scheduling queue of user gradation；
For several user identifiers in same scheduling queue, the order joined the team according to user identifier, successively to receive
Actual access bandwidth corresponding with user identifier access terminal corresponding with user identifier.
13. device according to claim 12, which is characterized in that the AM access module is additionally operable to：
In a timeslice, a timeslice is divided by several according to default proportionate relationship corresponding with user gradation
With the user gradation corresponding period, the ratio of the time span between each period is consistent with the proportionate relationship,
The user identifier in scheduling queue corresponding with the user's grade is dispatched within the period corresponding with user gradation.
14. the device according to claim 12 or 13, which is characterized in that the AM access module is additionally operable to：
In the case of there is no user identifier in a scheduling queue, terminate the scheduling to the scheduling queue, carry out to next
The scheduling of scheduling queue.
15. a kind of access system of WLAN, which is characterized in that including：Remote customer dialing authentication system RADIUS, connect
Enter controller AC and access point AP；
The RADIUS, for receiving the wireless negotiated speed of the current terminal to be accessed from the AC and current to be accessed
The user identifier of login user in terminal；According in advance be the user identifier represent user set by user gradation, should
The bandwidth application of the pre- first to file of user and the wireless negotiated speed received actually connect for the distribution of current terminal to be accessed
Enter bandwidth；And the information of the actual access bandwidth of distribution is sent to the AC；
The AC, for will be stepped on the wireless negotiated speed of the current terminal to be accessed from the AP and current terminal to be accessed
The user identifier of land user is transmitted to the RADIUS；And the information of the actual access bandwidth from the RADIUS is transmitted to
The AP；
The AP for determining the wireless negotiated speed of current terminal to be accessed, and the wireless negotiated speed is currently treated with this
The user identifier of login user is sent to the AC in access terminal；The information of the actual access bandwidth from the AC is received,
With the actual current terminal to be accessed of access bandwidth access.
