In the present embodiment, hot spot access device is the equipment that can at least provide two Wi-Fi hotspot connections, such as
Double frequency WiFi routers on sale or the double frequency WiFi handset that may be simultaneously operated in 2.4GHZ and 5GHZ.Double frequency Wifi refers to
Equipment supports 2.4GHz/5GHz dual-band radio signals at the same time, can support to include the complete wireless networks of 802.11a/b/g/n, its
Belong to the 5th generation Wi-Fi transmission technology.Wherein, 2.4GHz frequency ranges and 5GHz frequency ranges respectively have an advantage and disadvantage, the covering of 2.4GHz frequency ranges away from
From remote, property through walls is good, but poor anti-interference, and speed is lower, 5GHz frequency range strong interference immunities, and speed is high, but coverage distance is short,
Property through walls is poor.
First hot spot and second hot area of the present embodiment are exactly two hot spots that hot spot access device provides, wherein the first heat
Point and second hot area are usually two Wi-Fi hotspots for being operated in different frequency range, such as present most widely used 2.4GHZ and 5GHZ
Frequency range, when the frequency range of the first hot spot and second hot area can be respectively 2.4GHZ and 5GHZ or respectively 5GHZ and 2.4GHZ,
The present embodiment does not limit this, first hot spot of certain the present embodiment and the frequency range of second hot area be not limited to above-mentioned 5GHZ and
2.4GHZ。
In the present embodiment, the terminal of user has had already accessed to the first hot spot of hot spot access device, the mode of access
Usually user inputs the WiFi passwords (namely log-on message of the first hot spot) of the first hot spot by the operation interface of terminal, eventually
End carries out 4 handshake operations with the first hot spot, and during 4-Way Handshake, WiFi passwords are sent to the first hot spot, and first
Hot spot completes the verification of WiFi passwords, is verified then the first hot spot and the WiFi of terminal connections are established, otherwise connection failure.
After terminal and the first hot spot successful connection, transmission resources for transmitting data that terminal is provided by the first hot spot.When
When first hot spot nearby has a large amount of in running order same frequency range hot spot, the disturbing factor of the first hot spot sharply increases, and first
The WiFi signal quality of hot spot is decreased obviously；In addition, as user moves, terminal changes with WiFi distances, it is also possible to
Situations such as causing the WiFi signal quality of the first hot spot to decline.In consideration of it, in order to tackle the change of the signal quality of the first hot spot,
Detected for terminal and the connection status of the first hot spot, the connection status of terminal and the first hot spot can show the first heat
The signal strength that point provides for terminal, when good connection, the signal strength of the first hot spot of terminal access is high, Ke Yiwei
Terminal provides good data transfer.When connection status is poor, the signal strength of the first hot spot is low, the transmission provided for terminal
What is serviced is second-rate, it could even be possible to there is the situation of disconnecting.
During terminal accesses the first hot spot, both sides can produce largely interactive air message, hot spot access device
(such as router) can preserve the heading (beacon messages) of terminal transmission, and preserve end message (such as terminal of access
MAC Address etc.), afterwards, terminal can timing send beacon messages to the first hot spot, the first hot spot to beacon messages into
Row preserves.Usually, the information such as signal magnitude, signal value, noise magnitude, noise figure are included in beacon messages, it is contemplated that
The coverage of the hot spot of different frequency range is different, in order to increase the accuracy that the connection status of terminal and the first hot spot detects, this
In embodiment, terminal and the distance Distance Value of WiFi are further included in beacon messages, for terminal and the first hot spot
Connection status, can from terminal send beacon messages in extract signal magnitude, signal value, noise magnitude, noise figure, end
Analyzed with the information such as the distance of WiFi at end.Generally, the signal magnitude when user terminal, signal value are smaller, with Wi-Fi hotspot
Away from too far away, and when noise magnitude, noise figure are larger, terminal and the connection status of the first hot spot are poor.
The Beacon messages of the present embodiment are as shown in the table：
In order to simplify the judgment step to the connection status of terminal, connection status standard, the company are provided with the present embodiment
Connect and signal magnitude threshold value, signal value threshold value, noise magnitude, noise figure threshold value and terminal and hot spot are provided with status criteria

Wherein, in order to determine that terminal whether in the coverage of second hot area equipment, after S101, can obtain end
End and the actual range of access point apparatus and the coverage of second hot area equipment, are compared to obtain comparative result.Work as end
When in coverage of the end in second hot area, follow-up hot spot switching is just carried out.
According to it is above-mentioned to the connection procedure of terminal and the first hot spot according to, terminal established with hot spot when WiFi is connected, it is necessary to
The identity and the corresponding WiFi passwords of input of target hot spot are known, so by the first hot spot and the connection migration of terminal to second
On hot spot, terminal needs to know the required log-on message that connection is established with second hot area, could be carried out four times with second hot area
Shake hands, establish WiFi connections.Wherein, in order to avoid user finds second hot area and the corresponding password of input manually, reduce and use
Family is experienced, and in the present embodiment, using the connection between the first hot spot and terminal having built up, is sent out by the first hot spot to terminal
Second hot area link information is sent, which is used for terminal and determines to establish the login needed for connection with second hot area
Information.After S102, the login that terminal can determine to establish with second hot area needed for connection according to second hot area link information is believed
Breath.
In S102, log-on message can be carried in second hot area link information, then it is direct equivalent to by the first hot spot
The log-on message that terminal and second hot area are established needed for connection is sent to terminal, terminal can be connected directly from second hot area to be believed
Log-on message is extracted in breath.Using such a mode, the log-on message of second hot area terminal is sent to directly, terminal is without again
Log-on message is obtained by other means, and user can not have to the password of two hot spots of input, access the situation of the first hot spot
Under, terminal can get the information such as the password of second hot area automatically.
But in above-mentioned mode, the log-on message of second hot area is sent to terminal by the first hot spot, there is close
The possibility of code leakage, in order to protect the privacy of user, while in order to efficiently use the login of the hot spot accessed in terminal
Information.First it can determine whether second hot area was connected with terminal, if connecting, terminal can be from the historical connection information of itself
In find the log-on message of second hot area.
Wherein, before sending second hot area link information to terminal using the first hot spot, further include：
The identification information of terminal is sent to second hot area using the first hot spot；According to the identification information of terminal and second
The history linkage record of hot spot, judges whether second hot area connected terminal.
Generally, the hot spot of access terminal can retain relevant information of the end message as history linkage record, such as MAC
The information such as address, wherein the information that can be used for distinguishing each terminal can serve as identification information, so in the present embodiment, can
With by the MAC of terminal (Media Access Control or Medium Access Control, physical address) addresses or
Identification information of the information such as IMIE numbers as terminal, is connected in view of the first hot spot establishes WiFi in the terminal with the present embodiment
Afterwards, end message is just saved.The step of identification information of terminal is sent to second hot area by above-mentioned the first hot spot of utilization is real
It is that the identification information that terminal is obtained in the end message preserved from first hot spot (includes but not limited to the MAC of terminal on border
Location, No. IMIE), the identification information is sent to second hot area using the first hot spot.
Second hot area receive after, can utilize terminal identification information as index, from the history linkage record of itself
Whether inquiry connected the terminal, and query result is sky, then was not connected with, it is necessary to be believed the login of second hot area by the first hot spot
Breath is sent to terminal, and query result is non-NULL, then second hot area once accessed the terminal.
In the case of second hot area accessed the terminal, second hot area link information is sent to terminal using the first hot spot
Including：The identification information of second hot area is sent to terminal using the first hot spot, so that terminal is believed according to the identification of second hot area
Cease and obtain log-on message from the historical connection information that itself is preserved.
Wherein, for each hot spot, its corresponding SSID (Service Set Identifier, service set)
All it is different, so, identification information that can be using SSID as second hot area is sent to terminal, and terminal inquiry itself preserves
Historical connection information in whether there is the SSID, if so, then obtaining the corresponding log-on messages of the SSID.
For terminal, process is established with the second WiFi being connected, authentication is essential, so terminal and the second heat
Point establishes the log-on message needed for connection, includes the identification information SSID and authentication information of second hot area.
Wherein, it is contemplated that during user uses hot spot, it may modify to the log-on message of hot spot, such as
Modify at least one of user name or password, at this time, even if in the historical connection information that terminal inquiry itself preserves
There are the SSID, that is, even if terminal once accessed second hot area, the log-on message for the second hot area that terminal preserves may also
It is unable to Successful login second hot area.So in the present embodiment, second hot area obtains the identification of terminal transmission by the first hot spot
Information SSID by the authentication information of itself with after authentication information, if judging not being inconsistent for the authentication information of itself, passing through first
Hot spot is sent to terminal, is connected by terminal according to correct authentication information, foundation with the WiFi of second hot area.
In the present embodiment, for the first hot spot and second hot area, its bandwidth is fixed, accesses the terminal of hot spot
More, load is bigger, and the transfer resource that each terminal is got is fewer, if the unrestrictedly connection of receiving terminal, will lead
The connection status for having connected terminal is caused to be deteriorated, signal transmission quality reduces, in order to avoid such case occurs, it is preferred that
Before S102, further include：The terminal quantity of second hot area access and/or the connection status with each terminal are detected, according to the second heat
The terminal quantity of point access and/or the connection status with each terminal, judge whether second hot area can be with access terminal.If the
The terminal quantity saturation of two hot spots access, has reached the maximum in the case where ensureing the good connection of each terminal
Access quantity, or in the case that each terminal and the connection status of second hot area are not very good, then cannot inadequate second heat again
Point access new terminal, should terminate this handoff procedure, avoid causing the terminal for having connected second hot area situations such as suspension occur.
Wherein, if hot spot access device also has other at least one hot spots, the few hot spot of number of access terminals can be therefrom selected, then
The secondary process for carrying out above-mentioned S101-S104, realizes that hot spot switches.
If terminal quantity also has a certain distance, or most terminal and second from the upper limit that second hot area can access
The connection status of hot spot is all relatively good, then can carry out above-mentioned S102, and sending second hot area to terminal using the first hot spot connects
