Step 101, radio reception device is added up the situation receiving or send message under each transmission rate of this radio reception device in transmission rate set, obtain the statistical value that each transmission rate is corresponding, and the statistical value corresponding according to each transmission rate determines the weight that each transmission rate is corresponding.
Wherein, above-mentioned transmission rate set is the transmission rate set of the predetermined Beacon message of radio reception device.Wherein, this transmission rate set needs in the limited field of Beacon message transmitting spped rate, and the speed in this transmission rate set is all basic rate or forces speed.
In a kind of implementation of the present embodiment, radio reception device is added up the situation receiving message under each transmission rate of this radio reception device in transmission rate set, and obtaining statistical value corresponding to each transmission rate can be: radio reception device adopts R to this radio reception device
ithe probe requests thereby message received when sending Beacon message is added up, and obtains this radio reception device and adopts R
ithe number of probe requests thereby message received when sending Beacon message, and the sum of probe requests thereby message that this radio reception device receives; Above-mentioned probe requests thereby message is that the terminal equipment (such as: STA) of radio reception device association sends to above-mentioned radio reception device; Wherein, R
ifor the transmission rate in above-mentioned transmission rate set; I=1,2 ..., N, N are the number of the transmission rate comprised in above-mentioned transmission rate set.
In this implementation, the statistical value corresponding according to above-mentioned each transmission rate determines that weight corresponding to each transmission rate can be: radio reception device determines R
icorresponding weight is the subtraction function of Numi/Numt; Wherein, Numi is that radio reception device adopts R
ithe number of the probe requests thereby message received when sending Beacon message; Numt is the sum of the probe requests thereby message that radio reception device receives.
For example, an example of the subtraction function of Numi/Numt can as the formula (1):
Wherein, Q
ifor R

Below by instantiation, the present invention's method provided embodiment illustrated in fig. 1 is introduced.
The transmission rate set of the Beacon message that assumed wireless equipment is determined is for { 1,2,5.5,11}, in this transmission rate set, transmission rate is designated as R respectively
0, R
1, R
2and R
3, unit is MBPS (Megabitpersecond; Hereinafter referred to as: Mbps).
Example one
First, radio reception device adopts R to this radio reception device
ithe probe requests thereby message received when sending Beacon message is added up, and obtains this radio reception device and adopts R
ithe number of probe requests thereby message received when sending Beacon message, and the sum of probe requests thereby message that this radio reception device receives.Wherein, above-mentioned probe requests thereby message is that the terminal equipment (such as: STA) that radio reception device associates sends to above-mentioned radio reception device.
The most at first, there is no STA and access this radio reception device, so there is no STA and send probe requests thereby message to this radio reception device, so this radio reception device statistics obtains this radio reception device adopt R
ithe number of the probe requests thereby message received when sending Beacon message is 0, i.e. Num0=Num1=Num2=Num3=0; At this moment Numt=Num0+Num1+Num2+Num3=0.
Then, now Q can be determined according to formula (1)
0=Q
1=Q
2=Q
3=1.
Next, the product of the theoretical value of each transmission rate weight corresponding with above-mentioned each transmission rate is calculated, as the combined value that each transmission rate is corresponding.
Particularly, R
0, R
1, R
2and R
3theoretical value be respectively L
0=9Kbps, L
1=1900Kbps, L
2=4900Kbps, L
3=8100Kbps; Due to Q
0=Q
1=Q
2=Q
3=1, therefore R
0, R
1, R
2and R
3corresponding combined value is respectively T
0=9Kbps, T
1=1900Kbps, T
2=4900Kbps, T
3=8100Kbps.
Finally, radio reception device selects greatest combined value T
3corresponding transmission rate, as the transmission rate of Beacon message, namely selects 11Mbps to send Beacon message.
After after a while, have STA to access this radio reception device, radio reception device adopts R
3the number (Num3) of probe requests thereby message received when sending Beacon message, and the sum (i.e. Numt) of probe requests thereby message that this radio reception device receives all can increase, assumed wireless access device is to this radio reception device employing R
3after the probe requests thereby message received when sending Beacon message is added up, obtain Num3=10, the then Numt+Num3=0+10=10 preserved before Numt=;

1=1900Kbps, T
2=4900Kbps, T
3=0Kbps.
At this moment T
2maximum, so radio reception device selects T
2corresponding transmission rate, as the transmission rate of Beacon message, namely selects 5.5Mbps to send Beacon message.
By that analogy, As time goes on, the transmission rate of Beacon message can reduce and also can improve.It should be noted that, radio reception device adopts R
ithe number Numi of the probe requests thereby message received when sending Beacon message is accumulated value, and in computational process, this value does not reset; The total Numt of the probe requests thereby message that same radio reception device receives also is an accumulated value, and in computational process, this value can not reset equally.

First, radio reception device adopts R to this radio reception device
ipacket loss when sending datagram is added up, and obtains R
icorresponding packet loss.
The most at first, this radio reception device does not send datagram, so this radio reception device statistics obtains R
icorresponding packet loss is 0, i.e. D
0=D
1=D
2=D
3=0.
Then, now Q can be determined according to formula (2)
0=Q
1=Q
2=Q
3=1.
Next, the product of the theoretical value of each transmission rate weight corresponding with above-mentioned each transmission rate is calculated, as the combined value that each transmission rate is corresponding.
Particularly, R
0, R
1, R
2and R
3theoretical value be respectively L
0=9Kbps, L
1=1900Kbps, L
2=4900Kbps, L
3=8100Kbps; Due to Q
0=Q
1=Q
2=Q
3=1, therefore R
0, R
1, R
2and R
3corresponding combined value is respectively T
0=9Kbps, T
1=1900Kbps, T
2=4900Kbps, T
3=8100Kbps.
Finally, radio reception device selects greatest combined value T
3corresponding transmission rate, as the transmission rate of Beacon message, namely selects 11Mbps to send Beacon message.
After after a while, assumed wireless access device adopts R to this radio reception device
3after packet loss when sending datagram is added up, obtain D
3=50%, then Q
3=1-D
3=1-50%=1-0.5=0.5; And at this moment, Q
0=Q
1=Q
2=1.
Like this, acquisition R can be calculated
0, R
1, R
2and R
3corresponding combined value is respectively T
0=9Kbps, T
1=1900Kbps, T
2=4900Kbps, T
3=4050Kbps.
At this moment T
2maximum, so radio reception device selects T
2corresponding transmission rate, as the transmission rate of Beacon message, namely selects 5.5Mbps to send Beacon message.
By that analogy, As time goes on, the transmission rate of Beacon message can reduce and also can improve.
