Description
Technical field
The application is related to mobile communication technology field, more particularly to one kind realizes up-downgoing covering matching in wlan system
Method and wlan system.
Background technology
With the fast development that mobile communication business is applied and Internet service is applied, mobile subscriber does not require nothing more than mobile logical
Letter system can provide mobile communication business for it, also require that it can provide Internet service service.Therefore, it is many at present
Mobile terminal can be linked into as WLAN (WLAN) terminal by WAP (AP, Access Point)
In cable network, to obtain corresponding value-added service and Internet service.
Fig. 1 is the schematic flow sheet that WLAN terminal is associated with AP in the prior art.It is as shown in figure 1, of the prior art
The flow that WLAN terminal is associated with AP can include step as described below：
Step 101, WLAN terminal manages beacon (Beacon) frame to find AP by intercepting.
For example, as shown in figure 1, WLAN terminal finds whether have around it by intercepting the Beacon frames of down direction
AP.Wherein, Beacon frames are a kind of wireless management frames of broadcast, carry the information of the wireless service of AP issues, regular by AP
The WLAN terminal being sent to around it.
Step 102, detection process is carried out between WLAN terminal and AP.
For example, as shown in figure 1, WLAN terminal first sends a probe requests thereby (Probe Request) to AP, AP is received
After the probe requests thereby, a probe response (Probe Response) will be returned to the WLAN terminal, so as to complete above-mentioned spy
Survey process.
Step 103, process is authenticated between WLAN terminal and AP.
For example, as shown in figure 1, WLAN terminal first sends a certification request (Auth Request) to AP, AP is received
After the certification request, an authentication response (Auth Response) will be returned to the WLAN terminal, so as to complete above-mentioned certification
Process.
Step 104, process is associated between WLAN terminal and AP.
For example, as shown in figure 1, WLAN terminal first sends an association request (Association Request), AP to AP
After receiving the association request, an associated response (Association Response) will be returned to the WLAN terminal, so as to
Complete above-mentioned association process.
Step 105, WLAN terminal carries out the transmitting-receiving of data with establishing the AP associated.
By above-mentioned step 101~105, WLAN terminal can be established with AP and associate and carry out the transmitting-receiving of data.
It there is also some problems however, WLAN terminal of the prior art is associated with AP method.For example, above-mentioned
WLAN terminal is associated with AP method, and used up management frame is (for example, above-mentioned when accessing AP for WLAN terminal
Probe Request, Auth Request and Association Request) and down management frame (for example, above-mentioned
Beacon frames, Probe Response, Auth Response and Association Response) speed must identical (example
Such as, all it is 1Mbps).But because AP down transmitting power is typically greater than the uplink transmission power of WLAN terminal, therefore,
When WLAN terminal is distant from a distance from AP, it will occur due to up limited (i.e. the transmission power of WLAN terminal is insufficient) and
Up-downgoing is caused to cover unmatched situation.
Fig. 2 covers unmatched schematic diagram for the up-downgoing in wlan system in the prior art.As shown in Fig. 2 work as WLAN
When terminal is distant from a distance from AP, because AP down transmitting power is more than the uplink transmission power of WLAN terminal, therefore
WLAN terminal can receive the down management frame (for example, Beacon frames) of AP transmissions, but be sent by WLAN terminal up
Management frame is but likely to not received by AP, that is to say, that the descending coverage one in wlan system of the prior art
As both greater than up coverage, although therefore being easy to WLAN terminal occur when covering far point it can be seen that AP (is received
To AP signal) but the technical problem of the AP can not be accessed, so as to cause the Experience Degree of user poor.
In summary, in the wlan system of prior art, due to used up management when WLAN terminal accesses AP
The speed of frame and down management frame must be identical, therefore will appear from up-downgoing and cover unmatched situation.It is additionally, since existing skill
The speed of up management frame and down management frame can only be adjusted simultaneously in art, and can not individually adjust down management frame
Speed.So even if the speed of up-downgoing management frame is adjusted, uplink and downlink coverage will also expand or simultaneously simultaneously
Reduce, unmatched problem is covered so as to still solve up-downgoing.
