Fig. 5 is the flow chart of a kind of working channel method of adjustment according to an exemplary embodiment, and as shown in Figure 5, interaction agent is access point and terminal, comprises the following steps.
In step 501, the bit error rate information of at least one the terminal timing acquiring protocol layer be connected with current access point, the bit error rate information collected is sent to current access point by timing.
Wherein, protocol layer refers to the physical layer and MAC layer that 802.11 protocol layers comprise.The whole terminals connected with current access point all gather the bit error rate information of physical layer and MAC layer.Wherein, the error rate weighs the index that data transmit accuracy at the appointed time.The gross yards * 100% of the error code in the error rate=transmission/transmit.If there is error code just to have the error rate.Under normal conditions, the generation of error code is because in Signal transmissions, decay changes the voltage of signal, causes signal to be destroyed in the transmission, produces error code.The pulse that noise, alternating current or lightning cause, transmission equipment fault and other factors all can cause error code.In the disclosed embodiments, if access point number is too much in the working channel of work at present access point, then the serious interference between each access point, the error rate just can be higher.Wherein, at least one terminal be connected with current access point can gather a bit error rate information every Preset Time and report to current access point.The size of Preset Time can be 1 minute, 30 seconds etc., disclosure embodiment does not specifically limit this.
In step 502, current access point is after the bit error rate information receiving the transmission of at least one terminal, and whether the terminal number detecting bit error rate information and connection meets pre-conditioned; When the terminal number of bit error rate information and connection meets pre-conditioned, perform following step 503.
Wherein, when the terminal number detecting bit error rate information and connection meets pre-conditioned, following manner can be taked to realize:
Whether the error rate detecting the first preset number terminal is greater than predetermined threshold value, and whether the terminal number of connection is greater than the second preset number; When the error rate of the first preset number terminal is greater than predetermined threshold value, and when the terminal number connected is greater than the second preset number, determine that the terminal number of bit error rate information and connection meets pre-conditioned.
Wherein, the size of the first preset number and the second preset number can depend on the circumstances, and disclosure embodiment does not specifically limit this, only needs guarantee first preset number to be less than the second preset number.
In the disclosure is implemented, when the terminal number detecting bit error rate information and connection meets pre-conditioned, except taking aforesaid way and realizing, following two kinds of modes also can be taked to realize, that chooses in three kinds of modes in the specific implementation is any, disclosure embodiment does not specifically limit this, can depend on the circumstances.
Whether first kind of way, the error rate detecting the first preset number terminal are greater than predetermined threshold value; When the error rate of the first preset number terminal is greater than predetermined threshold value, determine to meet pre-conditioned.
Whether the terminal number that the second way, detection are connected with current access point is greater than the second preset number; When the terminal number be connected with current access point is greater than the second preset number, determine to meet pre-conditioned.
In step 503, when the terminal number of bit error rate information and connection meets pre-conditioned, current access point scanning work at multiple access points of other channels, and obtains the signal strength signal intensity of multiple access point.
Wherein, other channels are the channel that current access point can switch, and this scanning work is completed by the scan module of current access point.This scan module can scan the multiple access points at other multi-channel operation under current network conditions, and the signal strength signal intensity of the plurality of access point.Such as, the number of other channels is 13, then which each channel in these 13 channels of scanning had at the access point of work by scan module, and the signal strength signal intensity of each access point.
In the disclosed embodiments, chained list can be set up according to the multiple access point scanned and respective signal intensity in current access point.Wherein, with current access point, the number of chained list supports that the number of channel is identical.Also namely, the number of chained list equals the number of other channels.Comprise multiple node at a chained list, each node comprises two information, is respectively service set (SSID) and the signal strength signal intensity of the access point be scanned.
In step 504, to be switched channel, according to the signal strength signal intensity of the multiple access points scanned, is chosen in current access point in other channels.
In the disclosed embodiments, if the terminal number of the bit error rate information that current access point is corresponding and connection meets pre-conditioned, then show channel that current access point works due to the terminal number connected too much, signal disturbing between each access point is serious, and current access point need switch to the less channel of other interference by present channel.Wherein, in the signal strength signal intensity according to multiple access point, when choosing to be switched channel in other channels, following manner can be taked to realize:
For each channel in other channels, the cumulative signal strength signal intensity being connected to whole access points of channel, obtain signal strength signal intensity and; In other channels, choose signal strength signal intensity and minimum channel, signal strength signal intensity and minimum channel are defined as to be switched channel.
Because disclosure embodiment is that each channel that current access point is supported all establishes a chained list, in this chained list, include all access points and corresponding signal strength signal intensity that are operated in this channel.Therefore, the signal strength signal intensity of whole node in each chained list that can add up, obtain signal strength signal intensity and.All signal strength signal intensities and in, the minimum intensity of numerical value and corresponding channel are just to be switched channel.Signal strength signal intensity and less, show that in this channel, channel seizure ratio is lower, the signal disturbing between each access point is less, so choose this channel as to be switched channel.
In step 505, current access point is detected at least one terminal and whether is all supported to be switched channel; If at least one terminal all supports to be switched channel, then perform following step 506.
Because terminal is not all can carry out transfer of data in all channels, so current access point is after determining to be switched channel, also need to detect connected whole terminal and whether all support to be switched channel, also namely detect and whether can carry out transfer of data in this to be switched channel.Wherein, when whether at least one terminal described in described detection all supports described to be switched channel, following manner can be taked to realize:
