The flow chart of the antenna selecting method embodiment tri-of the wireless network access device that Fig. 4 provides for the embodiment of the present invention, as shown in Figure 4, the method for the present embodiment comprises:
Step S401, when subscriber equipment accesses, receive the probe request that subscriber equipment sends, and the signal that obtains subscriber equipment covers parameter.
Particularly, this step is identical with step S301.
Whether step S402, judge in the set of antenna sets shuttering to exist with described signal to cover optimal antenna gang form corresponding to parameter.
Particularly, after AP gets the signal covering parameter of STA, judge whether the set of antenna sets shuttering exists the optimal antenna gang form corresponding with this signal covering parameter, if exist, performs step S403, if do not exist, performs step S405.In the present embodiment, the set of antenna sets shuttering can be preset in AP, also the set of antenna sets shuttering can be do not preset.If default antenna sets shuttering set in AP, when STA accesses, if have in the set of antenna sets shuttering with the signal of STA and cover optimal antenna gang form corresponding to parameter, AP can directly select this optimal antenna gang form, perform step S403, if with the signal of STA, do not cover optimal antenna gang form corresponding to parameter in the set of antenna sets shuttering, AP need to judge that this signal covers optimal antenna gang form corresponding to parameter, performs step S405.If Non-precondition antenna sets shuttering set in AP, when STA accesses, AP need to judge that this signal covers optimal antenna gang form corresponding to parameter, performs step S405.
Step S403 selects to cover optimal antenna gang form corresponding to parameter with described signal in the set of antenna sets shuttering.
Particularly, this step is identical with step S302.
Step S404, used antenna sets corresponding to described optimal antenna gang form to be combined into subscriber equipment access service be provided.
Particularly, this step is identical with step S303.
Step S405, the signal quality of subscriber equipment while detect using respectively all possible antenna sets to be combined into subscriber equipment to provide access service.
Particularly, if with the signal of STA, do not cover optimal antenna gang form corresponding to parameter in the antenna sets shuttering set in AP, AP need to detect and use all antennas combinations that can provide to be respectively the signal quality of the STA of STA when access service is provided, travels through all possible antenna and combines.Detecting all possible antenna combination is to cover optimal antenna combination corresponding to parameter in order to find with the signal of STA.Wherein, the signal quality of STA comprises: at least one in the data transmission rate of the packet loss of STA transmission data, the signal strength signal intensity that STA receives, STA.
Step S406, the antenna sets of use signal quality optimum is combined into subscriber equipment provides access service.
Particularly, after detecting all possible antenna combination, select the antenna combination of signal quality optimum, this antenna combination is the optimal antenna combination that STA access AP is used, and STA is used this antenna combination can reach best communication quality.AP is used this antenna sets to be combined into STA access service is provided, and STA can reach best communication quality.When the signal quality of STA is STA while sending the packet loss of data, the antenna sets that packet loss is minimum is combined into the antenna combination of signal quality optimum; When the signal quality of STA is the time time delay that STA sends data, the antenna sets that sends the time delay minimum of data is combined into the antenna combination of signal quality optimum; When the signal quality of STA is STA while sending the shake of data, the antenna sets that sends the shake minimum of data is combined into the antenna combination of signal quality optimum.But in the antenna selecting method of the wireless network access device that the embodiment of the present invention provides, when the signal quality of STA is not limited to the above-mentioned parameter of mentioning, when the signal quality of STA so long as characterize the parameter of the signal quality of STA and get final product.
Step S407 is that described signal covers optimal antenna gang form renewal antenna sets shuttering set corresponding to parameter by the antenna sets cooperation of signal quality optimum.
Particularly, when making STA again access AP or during other STA accesses AP, can directly in the set of antenna sets shuttering, select to cover optimal antenna gang form corresponding to parameter with the signal of STA, in the antenna sets of using the signal quality optimum, be combined into after STA provides access service, the signal that it be this STA by this antenna sets cooperation that AP needs covers optimal antenna gang form renewal antenna sets shuttering set corresponding to parameter.Like this when STA accesses again, if the signal of STA covers the signal covering parameter that parameter is still this access, AP can be directly selects the optimal antenna gang form corresponding with this signal covering parameter in the set of antenna sets shuttering, uses correspondingly antenna sets to be combined into STA access service is provided.
Further, in step S407, by the antenna sets cooperation of signal quality optimum, be that optimal antenna gang form renewal antenna sets shuttering set corresponding to described signal covering parameter can also comprise: if surpass predetermined threshold value the turn-on time of subscriber equipment, by the antenna sets cooperation of signal quality optimum, be that described signal covers optimal antenna gang form renewal antenna sets shuttering set corresponding to parameter.Particularly, due to the method for the present embodiment for wireless network, subscriber equipment in wireless network in state movably, when in step S406, AP detect to be used all possible antenna sets to be combined into STA to provide access service in the process of the signal quality of STA, STA may be in mobile status, and the detection for signal quality is insecure in this case.Therefore also need to detect the time that antenna sets splice grafting that STA uses the signal quality optimum enters AP, if this time long enough, mean that STA is positioned at substantially fixing zone access AP, the now antenna of signal quality optimum combination should be the optimal antenna combination that can use at this zone of STA access AP, can reach best communication quality, the signal that is now STA by the antenna sets cooperation of signal quality optimum again covers optimal antenna gang form corresponding to parameter and upgrades the set of antenna sets shuttering.Need a default time threshold in AP, when the time of STA access AP surpasses this time threshold, judge the time long enough of STA access AP.If the time of STA access AP does not surpass this time threshold, think that this access of STA AP is not once stable access procedure, the antenna that obtains by detection combination not necessarily this signal covers optimal antenna gang form corresponding to parameter, now not to the antenna sets shuttering set upgraded.
The present embodiment, on the basis of the various embodiments described above, increased the renewal process to the antenna sets shuttering, provide a kind of adaptive optimal antenna to select mechanism, can improve further the speed of subscriber equipment access, save system resource, and make subscriber equipment reach best communication quality.
The signal of subscriber equipment of below take covers the quantity that parameter is subscriber equipment place signaling zone, the packet loss that the signal quality of subscriber equipment is subscriber equipment transmission data is example, and the antenna selecting method of the wireless network access device that the embodiment of the present invention is provided is further described.Be understandable that, when the signal covering parameter of subscriber equipment and the signal quality of subscriber equipment are other situation, antenna selecting method and the following embodiment of the spider lines access device that the embodiment of the present invention provides are similar, repeat no more herein.
The flow chart of the antenna selecting method embodiment tri-of the wireless network access device that Fig. 5 provides for the embodiment of the present invention, as shown in Figure 5, the method for the present embodiment comprises:
Step S501, when subscriber equipment accesses, receive the probe request that subscriber equipment sends, and obtains the quantity of subscriber equipment place signaling zone.
Particularly, when STA need to access AP, at first AP can receive the probe request that STA sends, and this probe request comprises the various information of STA, comprising the quantity of STA place signaling zone.Description for the quantity of STA place signaling zone can be with reference to Figure 1A and Figure 1B and related description.
Step S502 selects the optimal antenna gang form corresponding with the quantity of subscriber equipment place signaling zone in the set of antenna sets shuttering.
Particularly, be preset with the set of antenna sets shuttering in AP, this antenna sets shuttering set comprises multiple antenna sets shuttering, and comprises the quantity of STA place signaling zone and the corresponding relation of antenna sets shuttering, the corresponding antenna sets shuttering of every kind of quantity of STA place signaling zone.The quantity of STA place signaling zone and the corresponding relation of antenna sets shuttering can be preset in by the mode of artificial setting in AP, also can automatically be identified and are stored in AP by AP.The antenna sets that this antenna sets shuttering is corresponding is combined into STA and accesses the optimal antenna template that this AP can be used, and STA is used antenna sets splice grafting that this antenna sets shuttering is corresponding to enter this AP can reach best communication quality.AP, by the quantity of the STA place signaling zone that obtains, selects the optimal antenna gang form corresponding with the quantity of this STA place signaling zone.
Step S503, used antenna sets corresponding to described optimal antenna gang form to be combined into subscriber equipment access service be provided.
Particularly, after AP determines the optimal antenna gang form used, the STA that uses this optimal antenna gang form respective antenna to be combined as access provides access service.Saved like this when STA access AP, AP travels through all antennas and combines the required time, has improved the speed of STA access, has saved system resource, and used antenna sets corresponding to optimal antenna gang form to be combined into STA access service is provided, made STA reach best communication quality.
For example AP has 4 antennas, can use 1 to 4 antenna to provide access service for STA, in antenna sets shuttering set in AP, the signaling zone of STA with the corresponding relation of optimal antenna gang form is: STA is corresponding 2 antennas in a signaling zone, STA is corresponding 3 antennas in two signaling zones, and STA is corresponding 4 antennas in three signaling zones.When STA accesses, the detectable signal frame judgement STA that AP sends by STA is arranged in 2 signaling zones, and AP selects 3 antennas to provide access service for STA, and now STA can reach best communication quality.
The present embodiment, when subscriber equipment accesses, the probe request sent by receiving subscriber equipment, obtain the quantity of subscriber equipment place signaling zone, select the optimal antenna gang form corresponding with the quantity of this subscriber equipment place signaling zone in default antenna sets shuttering set, and use antenna sets that this optimal antenna gang form is corresponding to be combined into subscriber equipment to provide access service, saved when subscriber equipment access of radio network access device, wireless network access device travels through all antennas and combines the required time, improved the speed of subscriber equipment access, saved system resource, and make subscriber equipment reach best communication quality.
The flow chart of the antenna selecting method embodiment five of the wireless network access device that Fig. 6 provides for the embodiment of the present invention, as shown in Figure 6, the method for the present embodiment comprises:
Step S601, when subscriber equipment accesses, receive the probe request that subscriber equipment sends, and obtains the quantity of subscriber equipment place signaling zone.
Particularly, this step is identical with step S501.
Step S602, judge in the set of antenna sets shuttering whether have the optimal antenna gang form corresponding with the quantity of subscriber equipment place signaling zone.
Particularly, after AP gets the quantity of STA place signaling zone, judge whether the set of antenna sets shuttering exists the optimal antenna gang form corresponding with the quantity of STA place signaling zone, if exist, perform step S603, if do not exist, perform step S605.In the present embodiment, the set of antenna sets shuttering can be preset in AP, also the set of antenna sets shuttering can be do not preset.If default antenna sets shuttering set in AP, when STA accesses, if the optimal antenna gang form corresponding with the quantity of STA place signaling zone arranged in the set of antenna sets shuttering, AP can directly select this optimal antenna gang form, perform step S603, if there is no the optimal antenna gang form corresponding with the quantity of STA place signaling zone in the set of antenna sets shuttering, AP need to judge the optimal antenna gang form corresponding to quantity of this STA place signaling zone, performs step S605.If Non-precondition antenna sets shuttering set in AP, when STA accesses, AP need to judge the optimal antenna gang form that the quantity of this STA place signaling zone is corresponding, performs step S605.
Step S603 selects the optimal antenna gang form corresponding with the quantity of subscriber equipment place signaling zone in the set of antenna sets shuttering.
Particularly, this step is identical with step S502.
Step S604, used antenna sets corresponding to described optimal antenna gang form to be combined into subscriber equipment access service be provided.
Particularly, this step is identical with step S503.
Step S605, the packet loss while detect using respectively all possible antenna sets to be combined into subscriber equipment to provide access service.
Particularly, if there is no the optimal antenna gang form corresponding with the quantity of STA place signaling zone in the antenna sets shuttering set in AP, AP need to detect and use all antennas combinations that can provide to be respectively the packet loss of STA when access service is provided, and travels through all possible antenna and combines.Detecting all possible antenna combination is in order to find the optimal antenna combination corresponding with the quantity of STA place signaling zone.
Step S606, used the minimum antenna sets of packet loss to be combined into subscriber equipment access service be provided.
Particularly, after detecting all possible antenna combination, select the antenna combination that packet loss is minimum, this antenna combination is the optimal antenna combination that STA access AP is used, and STA is used this antenna combination can reach best communication quality.AP is used this antenna sets to be combined into STA access service is provided, and STA can reach best communication quality.
Step S607, optimal antenna gang form corresponding to the quantity that minimum antenna sets cooperation is subscriber equipment place signaling zone by packet loss upgrades the set of antenna sets shuttering.
Particularly, when making STA again access AP or during other STA accesses AP, can directly in the set of antenna sets shuttering, select the optimal antenna gang form corresponding with the quantity of STA place signaling zone, using the minimum antenna sets of packet loss to be combined into after STA provides access service, the optimal antenna gang form renewal antenna sets shuttering set that the quantity that it be this STA place signaling zone by this antenna sets cooperation that AP needs is corresponding.Like this when STA accesses again, the quantity of STA place signaling zone when if the quantity of STA place signaling zone still accesses for this, AP can be directly selects the optimal antenna gang form corresponding with the quantity of this STA place signaling zone in the set of antenna sets shuttering, uses correspondingly antenna sets to be combined into STA access service is provided.
Further, in step S407, optimal antenna gang form corresponding to the quantity that minimum antenna sets cooperation is subscriber equipment place signaling zone by packet loss upgrades the set of antenna sets shuttering and can also comprise: if surpass predetermined threshold value the turn-on time of subscriber equipment, optimal antenna gang form corresponding to the quantity that minimum antenna sets cooperation is subscriber equipment place signaling zone by packet loss upgrades the set of antenna sets shuttering.Particularly, due to the method for the present embodiment for wireless network, subscriber equipment in wireless network in state movably, in step S406, AP detect to be used all possible antenna sets to be combined into STA provides in the process of packet loss of access service, STA may be in mobile status, and the detection for packet loss is insecure in this case.Therefore also needing to detect STA uses the minimum antenna sets splice grafting of packet loss to enter the time of AP, if this time long enough, mean that STA is positioned at substantially fixing zone access AP, the antenna combination that now packet loss is minimum should be the optimal antenna combination that can use at this zone of STA access AP, can reach best communication quality, optimal antenna gang form corresponding to the quantity that now minimum antenna sets cooperation is STA place signaling zone by packet loss again upgrades the set of antenna sets shuttering.Need a default time threshold in AP, when the time of STA access AP surpasses this time threshold, judge the time long enough of STA access AP.If the time of STA access AP does not surpass this time threshold, think that this access of STA AP is not once stable access procedure, the antenna that obtains by the detection combination optimal antenna gang form that not necessarily this signal cover type is corresponding, now not to the antenna sets shuttering set upgraded.
The present embodiment, on the basis of the various embodiments described above, increased the renewal process to the antenna sets shuttering, provide a kind of adaptive optimal antenna to select mechanism, can improve further the speed of subscriber equipment access, save system resource, and make subscriber equipment reach best communication quality.
