As shown in Figure 1, Fig. 1 is a kind of file transmitting method flow chart shown according to an exemplary embodiment, this method
It can be used in wireless access point device, include the following steps：
In a step 101, the first signal strength of associated terminal is detected.
Executive agent in the disclosure can be AP, which can be the wireless office being made of two or more AP
Any of which AP in the net of domain；The executive agent can also be wireless control be connected with each AP, for controlling each AP
Device (Access Controller, AC) is illustrated by taking AP as an example in the disclosure.
Terminal in the disclosure can be any intelligent terminal with function of surfing the Net, for example, can be specially mobile phone, flat
Plate computer, personal digital assistant (Personal Digital Assistant, PDA) etc..Wherein, terminal can pass through wireless office
Domain net couple in router, and pass through the server on router access public network.
In the wireless network, terminal will access the wireless network usually will send the probe requests message to AP, and terminal can
Can also send the probe requests message in a manner of unicast in a broadcast manner, in the disclosure in the way of unicast for carry out
Illustrate, the strongest AP of usual terminal signal strength into the wireless network sends probe requests thereby (Probe request) message, so
The AP is to terminal replies probe response (Probe response) message afterwards.In the feelings for needing certification that could access wireless network
Under condition, terminal also needs to send certification (Authentication) message, such as password to AP, is tested authentication information by AP
Card, in the case where certification passes through, the terminal association AP, and the wireless network of AP offers is provided.
In disclosure step, terminal associated with the AP may have multiple, and AP monitors the signal strength of each terminal in real time.
In order to mutually be distinguished with the signal strength from AP that terminal detects, the signal for carrying out self terminal for detecting AP in the disclosure is strong
Degree is known as the first signal strength, and the signal strength from AP that terminal detects is known as second signal intensity.The first of terminal
Signal strength can be for example received signal intensity instruction (Received Signal Strength Indication,
RSSI), in disclosure step, AP obtains the signal strength of terminal based on the message for carrying out self terminal.
In the disclosure, after the wireless network that terminal accesses AP offers, the message interacted between AP includes a variety of
Type.Such as in 802.11 wireless networks, type of message includes data message, management message and control message.Management report
Text can be subdivided into the subtypes such as beacon (Beacon) message, the probe requests message, detection response message and message identifying again
Message.The first signal that AP can access terminal by the message of any of the above described type come self terminal received is strong
Degree.
In a step 102, judge whether the first signal strength is less than signal strength threshold.
In disclosure step, signal strength threshold is set based on empirical value, and signal strength threshold can be understood as terminal
Positioned at the signal strength that AP is able to detect that when remote position with a distance from associated AP, the terminal energy on the remote position
The wireless signal strength of the AP enough received is weaker, can not obtain preferable online experience.
In step 103, it when being judged as that the first signal strength is less than signal strength threshold, reduces to the terminal sending tube
The power of message is managed, so that terminal is released when detecting the second signal intensity from AP less than roaming threshold value with the AP's
Association.
When AP is judged as that first signal strength is not less than signal strength threshold, illustrate that terminal distance AP is closer, AP is not
Do any processing.
When AP is judged as that the signal strength is less than signal strength threshold, illustrates terminal distance AP farther out or terminal is just remote
From the AP, AP reductions in this case are sent to the transmission power of the management message of the terminal.
In the disclosure, which may include beacon message and/or the uni-cast probe message for the terminal.
Due to the difference of manufacturer terminal, the difference of terminal type, the type of message that each terminal is supported is also different, such as makes
Beacon message is supported with the terminal of Intel network interface cards, and probe messages are supported using the terminal of some other network interface cards.Pipe in the disclosure
It may include beacon message and/or uni-cast probe message to manage message.Which kind of message what is supported in uncertain present terminal is
In the case of, in order to the various types of terminal of compatibility, AP can reduce the hair of beacon message and uni-cast probe message
Send power.
In the disclosure, the mode that AP reduces the transmission power of management message may include：
The transmission power for reducing management message, after sending message to terminal, then detection carrys out the first signal of self terminal
Intensity continues to reduce management if the first signal strength that this first signal intensity ratio last time detected detects is low
The transmission power of message.Wherein, AP can reduce the transmission power of management message as unit of predetermined power such as 1db~2db.
If the first signal strength that this first signal intensity ratio last time detected detects is low, it may be said that bright terminal
It is more farther apart from associated AP than last time, thus AP can continue reduce transmission power, with enable the terminals to faster with the AP
Connection is released, with the stronger AP of correlation signal intensity.
In the disclosure, the mode that AP reduces the transmission power of management message can also include：
The roaming threshold value being arranged in terminal is obtained, the transmission power of management message is reduced based on roaming threshold value.
For example, AP can be using the signal strength not higher than roaming threshold value as the second signal intensity of itself, to determine hair
Send power.Since management message will produce decaying during being sent to terminal, thus with second not higher than roaming threshold value
Signal strength manages the transmission power of message to determine, it will be able to so that the second signal intensity from AP that terminal detects is low
In roaming threshold value, thus with AP disassociations.
In the disclosure, the mode that AP reduces the transmission power of management message can also include：
The difference for the second signal intensity and roaming threshold value from AP that terminal calculates is obtained, AP is reduced based on the difference
Manage the transmission power of message.
For example, AP still reduces transmission power as unit of predetermined power, then terminal receive the reduction transmission power it
After message afterwards, current first signal strength from AP is obtained, and current first signal strength and roaming threshold value are done
Compare and obtain difference, AP continues to reduce transmission power based on the difference, so that the difference that terminal obtains is not more than 0, Neng Goujin
Fast releasing is associated with the AP's.
In above process, when AP detects terminal and AP disassociations；Or detect that the first signal for carrying out self terminal is strong
Degree becomes strong, and when which is higher than signal strength threshold, AP no longer reduces the transmission power of management message, and restores it
Preceding reduced transmission power.
As shown in Fig. 2, Fig. 2 is another file transmitting method flow chart shown according to an exemplary embodiment, the party
Method can be used in wireless terminal device, include the following steps：
In step 201, the second signal intensity of associated AP is detected.
In conjunction with embodiment illustrated in fig. 1, terminal is associated with AP, accesses after the wireless network of AP offers, between AP
There is the interaction of message.Terminal determines the second signal intensity from AP based on the beacon message or probe messages received.
In step 202, judge second signal intensity whether less than roaming threshold value.
In the disclosure, terminal is located in the WLAN being made of multiple AP, when weaker from associated AP signals,
And the signal from other AP it is stronger when, can release with the connection of associated AP, roam on other AP.
In step 203, when being judged as second signal intensity less than roaming threshold value, releasing is associated with AP's, the second letter
Number intensity is caused by the transmission power that AP reduces management message less than roaming threshold value.
When terminal is judged as second signal intensity less than roaming threshold value, it can release and to be associated with the AP.
Terminal release with before being associated with of the AP, it can be determined that whether be able to detect that the stronger AP of signal strength, such as
Fruit is judged as detecting the stronger AP of signal strength, can release and is associated with current AP, and with the stronger AP of signal strength
It is associated.
For supporting the terminal of beacon message, when detecting that the transmission power of the beacon message from AP declines, judge
It dies down for the signal strength of AP.Although supporting the terminal of beacon message that can also receive the uni-cast probe report that transmission power has dropped
Text, but since the terminal only supports beacon message, thus the uni-cast probe message does not influence the terminal, since detection is reported
Text is unicast fashion transmission thus is not also had an impact to other-end.
For supporting the terminal of probe messages, when detecting that the transmission power of the uni-cast probe message from AP declines,
It is judged as that the signal strength of AP dies down.Although the terminal of probe messages is supported also to will receive the beacon report that transmission power has dropped
Text, but beacon message does not have an impact the terminal, and the terminal of other support beacon messages for being associated with the AP, such as
Fruit terminal distance AP would not more closely influence the online experience of the terminal, if it is possible to influence the terminal, illustrate the terminal
Distance AP farther out, needs the stronger AP of correlation signal intensity.
The transmission power for the message that terminal can be received by the transmission power for the message for receiving this with last time
It is compared, to determine that transmission power declines.
As shown in figure 3, Fig. 3 is a kind of wireless access control application scenarios of the disclosure shown according to an exemplary embodiment
Schematic diagram.In scene shown in Fig. 3, including：AP 1, AP 2 and millet smart mobile phone as terminal.Wherein 1 Hes of AP
AP 2 form WLAN, millet smart mobile phone enter the WLAN after, due to distance AP1 closer to, thus with
AP 1 is associated.AP 1 passes through the first signal strength with millet smart mobile phone mutual message detection millet smart mobile phone.One section
Millet smart mobile phone is moved to close to the direction of AP 2 after time, and distance AP 1 is increasingly remoter, and at this moment AP 1 detects first
Signal strength dies down, and the first signal strength is compared with preset signal strength threshold, and being less than in the first signal strength should
When signal strength threshold, AP 1 reduces the transmission power of beacon message and the uni-cast probe response for being sent to the millet smart mobile phone
The power of message after millet smart mobile phone receives message, detects the second signal weakened of AP 1, by second signal
Intensity is compared with roaming threshold value, when second signal intensity is less than roaming threshold value, detects the third signal from AP 2
Intensity, and it is judged as that third signal strength is higher than second signal intensity, thus release and be associated with AP 1, and it is related to AP 2
Connection.
