In fifth embodiment of the invention, give a kind of specific implementation of above-mentioned steps 103 '.See Fig. 3, above-mentioned steps 103 ' regulates the power of the signal amplifier of AP equipment to make described AP equipment enter anti-interference state according to described abnormal Exception Type with the signal condition of the terminal of described AP equipment connection, comprising:
C1. when the current power of the signal amplifier of AP equipment does not reach maximum preset Modulating Power, if it is abnormal that described exception is the first kind, and being less than the first preset strength threshold value with the signal strength signal intensity of the terminal of described AP equipment connection, then the power heightening the signal amplifier of AP equipment makes described AP equipment enter anti-interference state;
C2. when the current power of the signal amplifier of described AP equipment is not low to moderate minimum default Modulating Power, if it is abnormal that described exception is Second Type, and being greater than the second preset strength threshold value with the signal strength signal intensity of the terminal of described AP equipment connection, then the power turning down the signal amplifier of AP equipment makes described AP equipment enter anti-interference state;
Wherein, the first preset strength threshold value is greater than the second preset strength threshold value.Wherein, the first preset strength threshold value is the lowest signal intensity that terminal normal received signal needs, as 40dBm.Second preset strength threshold value is the highest signal strength that terminal normal received signal needs, as 80dBm.
Those skilled in the art will be understood that above-mentioned first intensity predetermined threshold value and the second intensity predetermined threshold value are only citing; other existing or first intensity predetermined threshold value that may occur from now on and the second predetermined threshold value are as being applicable to the embodiment of the present invention; also within scope should being included in, and this is contained at this with way of reference.
In the present embodiment, when determining that network radio frequency abnormal state is first kind exception, show that the terminal that is connected with AP within the scope of AP equipment cannot normally demodulation, the first preset strength threshold value is less than with the signal strength signal intensity of the terminal of described AP equipment connection if now get, so prove that the power of the signal amplifier of AP equipment is really lower, in order to not affect and the normal access of the terminal of described AP equipment connection and demodulation, the power now should heightening the signal amplifier of AP equipment makes described AP equipment enter anti-interference state.And when determining that network radio frequency abnormal state is Second Type exception, show the data communication that there are non-AP needs in a large number within the scope of AP equipment, the second preset strength threshold value is greater than with the signal strength signal intensity of the terminal of described AP equipment connection if now get, then prove that the power of the signal amplifier of AP equipment is really higher, now, the power should turning down the signal amplifier of AP equipment makes described AP equipment enter anti-interference state, and the weak signal needed to make non-AP equipment and interference signal can not play the effect of amplification or directly be subject to the effect that circuit suppresses and be left in the basket.
Wherein, before the power of signal amplifier heightening AP equipment, need the current power of the signal amplifier determining AP equipment not reach maximum preset Modulating Power, otherwise just there is no need to carry out power adjustments.In like manner, before the power of signal amplifier turning down AP equipment, need the current power of the signal amplifier determining AP equipment not to be low to moderate minimum default Modulating Power, otherwise just there is no need to carry out power adjustments.
In sixth embodiment of the invention, see Fig. 4, in execution above-mentioned steps 101 or step 101 ' before, described method also comprises step 90-100.In the present embodiment, in execution above-mentioned steps 101 or step 101 ' before, first judge whether to need to enter the anti-interference state of AP equipment (namely determine that whether network radio frequency state is abnormal, and regulate the power of the signal amplifier of AP equipment according to Exception Type with the signal condition of the terminal of described AP equipment connection).Concrete judgment mode is: the signal strength signal intensity monitoring the beacon information of neighbor AP.When the signal strength signal intensity of the beacon information determining neighbor AP equipment is greater than the second predetermined threshold value as 30dBm or 35dBm, proof needs to enter the anti-interference state of AP equipment, at this time performs the network radio frequency state determined within the scope of access point AP equipment again and whether extremely waits subsequent operation.If the signal strength signal intensity monitoring the beacon information of neighbor AP equipment never more than the second predetermined threshold value, then there is no need to enter the anti-interference state of AP equipment.Such process, can maximize saving energy consumption.
Those skilled in the art will be understood that above-mentioned second predetermined threshold value is only citing; other existing or second predetermined threshold value that may occur from now on are as being applicable to the embodiment of the present invention; also within scope should being included in, and this is contained at this with way of reference.
Step 90: in each predetermined period, monitors the signal strength signal intensity of the beacon information of neighbor AP equipment.
In this step, the signal strength signal intensity of the beacon information of neighbor AP equipment is monitored in each predetermined period, when the signal strength signal intensity of the beacon information of neighbor AP equipment is greater than the second predetermined threshold value, prove that current scene belongs to dense deployment scene, now need opening network radio frequency status monitoring pattern, namely need to enter the anti-interference state of AP equipment, judge that within the scope of AP equipment, whether network radio frequency state is abnormal, as exception, then need automatically to regulate the power of the signal amplifier of AP equipment according to Exception Type and with the signal condition of the terminal of AP equipment connection.
Step 100: judge whether the signal strength signal intensity of the beacon information of neighbor AP equipment is greater than the second predetermined threshold value, if so, then performs above-mentioned steps 101 or step 101 '; Otherwise, continue to perform step 90.
In this step, when whether the signal strength signal intensity of the beacon information judging neighbor AP equipment is greater than the second predetermined threshold value, can judge whether the signal strength signal intensity of the beacon information of neighbor AP equipment continues to be greater than the second predetermined threshold value in preset time period, if so, then perform above-mentioned steps 101.The benefit of such judgement is, ensures accuracy or the validity of judged result.Because the signal strength signal intensity of the beacon information of neighbor AP equipment is greater than the second predetermined threshold value when putting sometime and do not mean that the signal strength signal intensity of the beacon information of neighbor AP equipment is genuine larger, it is likely the transient rise of the signal strength signal intensity that the interference of other equipment or other reasons cause, if just perform step 101 or step 101 according to this result ', likely can waste resource and power consumption, do the judgement of meaningless network radio frequency state.
