Embodiment
The invention discloses a kind of WAP cut-in method; Comprise: probe request is sent to WAP in the terminal, and the probe request that the WAP receiving terminal sends judges that whether self load is greater than preset threshold value; When self load is satisfied preset condition greater than preset threshold value and said probe request; Calculate and send parameter, and send probing response frame with said transmission parameter to said terminal, the terminal receives and obtains the transmission parameter of each said probing response frame; And, insert the lighter WAP of load according to said transmission parameter.
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of the invention discloses a kind of WAP cut-in method, be applied to following scene: two or more AP have identical SSID, and the terminal can be connected to wireless network through any AP; In order to be connected to AP; Probe request is sent with the form of radio broadcasting in the terminal, and each AP can receive said probe request, below is that example describes with any AP; As shown in Figure 1, said method comprises:
The probe request (Probe request) that the S101:AP receiving terminal sends;
S102: said AP judges that whether the load capacity of self is greater than preset threshold value;
Wherein, the load capacity of AP self can be judged through the current terminal quantity that has inserted this AP, also can judge with the current data traffic of this AP.Which kind of no matter judge, as long as load capacity greater than pre-set threshold, thinks that promptly this AP is in overload with mode.
S103: when self load capacity satisfies preset condition greater than preset threshold value and said probe request, calculate and send parameter;
Wherein, preset condition can be specially: (Media Access Control, MAC) address is not included in and connects in the tabulation medium access control in the probe request.
Because the MAC Address that carries in the probe request is its unique identification that sends the terminal; If this MAC Address is not present in the tabulation of connection of said AP; The terminal that then shows this MAC Address sign also is not connected with said AP; In order to make the heavy AP of load no longer insert new terminal, need to calculate and send parameter, with the loading condition of informing the said AP in terminal through the transmission parameter.
If this MAC Address is present in the tabulation of connection of this AP; Then this AP has been inserted at the terminal of this MAC Address sign, then need not to inform the loading condition of the said AP in this terminal, at this moment again; Useless probing response frame need be do not produced, normal wireless network traffic can be do not influenced.
In addition, preset condition also can be specially empty condition, promptly calculate to send load that the precondition of parameter has only AP self greater than preset threshold value, and does not have other condition.In practical application, can set the content of preset condition according to real needs, present embodiment is not done qualification.
In this step, send parameter and refer to parameter predefined, signal when sending probing response frame, can comprise:
The signal of said probing response frame sends intensity; Perhaps,
The transmission delay of said probing response frame; Perhaps,
The signal of said probing response frame sends intensity and transmission delay.
Correspondingly, in the present embodiment, calculate to send parameter and comprise: the signal that calculates said probing response frame sends at least one in the transmission delay of intensity and said probing response frame, wherein, the signal of said probing response frame send intensity computational methods can for:
Confirm the load factor that said WAP is current; Can calculate with the terminal amount of the current access of said AP; Promptly use formula: load factor=(the maximum terminal quantity that the number of terminals/AP of the current access of AP can insert) * 100%, calculate, also can calculate with the current data traffic of said AP; Promptly use formula: load factor=(maximum rate of AP present flow rate/AP) * 100%, calculate.
After calculating load factor; Again according to the minimum transmit signal strength of the radio frequency of said load factor and said WAP, radio frequency maximum adjustable joint signal strength signal intensity amplitude; The signal that calculates said probing response frame sends intensity, and computing formula is: the minimum transmit signal strength of the emissive porwer of signal=radio frequency+radio frequency maximum adjustable joint signal strength signal intensity amplitude * (1-load factor).
The computational methods of the transmission delay of said probing response frame are:
Confirm the load factor that said WAP is current, computational methods as stated;
According to the peak signal time delay of said load factor and said WAP, calculate the post-dialling delay of said probing response frame, computing formula is: post-dialling delay=peak signal time delay * load factor.
Can be found out that by above-mentioned formula load factor is big more, then the emissive porwer of signal is more little, and the transmission delay of signal is big more, that is, the load of AP is heavy more, and the signal strength signal intensity of its feedback probing response frame is more little, and time delay is big more.
Need to prove that except using the aforementioned calculation formula calculates, post-dialling delay also can be set to infinity, when the transmission delay of signal is infinitely great, can regards the probe request that AP sends the terminal as and not do any response.
S104: send probing response frame (Probe response) with said transmission parameter to said terminal, so that the lighter WAP of load according to said transmission parameter, is inserted in said terminal.
That is to say; Signal emissive porwer to calculate among the S103 is sent probing response frame; Or the post-dialling delay transmission probing response frame to calculate among the S103, perhaps, send probing response frame with signal emissive porwer and the post-dialling delay that calculates among the S103.
The described WAP cut-in method of present embodiment, in the load of AP self greater than threshold value, i.e. when load is big; AP calculates the transmission parameter, sends probing response frame according to sending parameter to the terminal, and is heavier to inform the current load in terminal self; Compare with existing cut-in method, said method can initiatively that load is heavier information notification terminal, so that reduce the probability that the heavier AP of load is selected at the terminal; But not refuse the access at terminal passively; Thereby the problem that the terminal for a long time can't access of radio network can not appear, and, realized the load balancing of AP in the network.
Disclosed another the access point cut-in method of the embodiment of the invention; With said method accordingly, the executive agent of the said method of present embodiment is to send probe request to AP, and receives the terminal of the probing response frame that AP returns; As shown in Figure 2, said method comprises:

S202: the terminal receives the probing response frame that said a plurality of AP sends, and is of above-mentioned embodiment, and probing response frame is to be calculated by each WAP to send parameter, and send with said transmission parameter;
Be not more than the WAP of preset threshold value for load capacity; Send parameter and be the transmission parameter of confirming according to prior art; For the WAP of load capacity, send the signal transmission intensity that parameter comprises said probing response frame greater than preset threshold value; Perhaps, the transmission delay of said probing response frame; Perhaps, the signal of said probing response frame sends intensity and transmission delay.
S203: the transmission parameter of obtaining each probing response frame;
Usually; Probe request is sent with the form of radio broadcasting in the terminal; Arbitrary AP with identical SSID can receive said probe request in the range of receiving of himself, corresponding, and the terminal also can receive the probing response frame that two or more AP send usually; For each probing response frame, all carry out the described operation of S203.For a plurality of probing response frames, the terminal can obtain a plurality of transmission parameters, and each sends the loading condition that parameter has all reflected the AP that it is corresponding.
Probing response frame probing response frame probing response frame S204:, insert the lighter WAP of load according to said transmission parameter;
When the said transmission parameter signal that is probing response frame sent intensity, the signal of terminal Access Probe response frame sent the bigger WAP of intensity; When said transmission parameter is the transmission delay of probing response frame, the less WAP of transmission delay of terminal Access Probe response frame.
When the said transmission parameter signal that is probing response frame sends intensity with transmission delay, the signal transmission intensity or the less WAP of transmission delay of terminal Access Probe response frame.
Intensity is big more because the signal of probing response frame sends, and the transmission delay of probing response frame is more little, and the load of the AP that it is corresponding is just more little, so the terminal total energy inserts the lighter AP of load, and can not insert the heavier AP of load.
The described WAP cut-in method of present embodiment, the terminal obtains the transmission parameter from the probing response frame that the AP that receives feeds back, and different transmission parameters reflects the loading condition of the AP that it is corresponding; The lighter AP of load can be inserted through relatively sending parameter in the terminal, compares with existing cut-in method; Said method makes the terminal can on purpose select the lighter AP of load; Avoided request repeatedly to insert the heavy AP of load, therefore, the problem of having avoided the user can't surf the Net for a long time; Realized the load balancing of AP.
