For example, terminal device can detect whether WIFI signal automatically, enter WIFI access point
During the region of WIFI signal covering, terminal device detects the WIFI signal of the WIFI access points, at this point, terminal device determines end
Whether the movement speed of end equipment is less than or equal to the first predetermined threshold value, and the first predetermined threshold value can be according to historical statistics
The user of using terminal equipment is averaged the speed of travel to determine, e.g., the user of the using terminal equipment of historical statistics averagely walks
Speed is 5km/h or 5~7m/s, and terminal device can save as the first predetermined threshold value as 5km/h or 5~7m/s.And it determines
It, can be with when whether the Strength Changes value of the WIFI signal of WIFI access points is less than or equal to the second predetermined threshold value in preset time
It is the use for the using terminal equipment that edge to center or center to edge are covered according to the WIFI signal of the WIFI access points of statistics
The family travel time that is averaged determines preset time, and the letter at WIFI signal covering center to the edge according to the WIFI access points of statistics
Number difference determines the second predetermined threshold value.Such as, when more than above-mentioned 5~7m/s of the speed of travel, user is average just can in 2s
Edge is run to from the WIFI signals of WIFI access points covering center, and the changing value of signal is 5dBm, in this manner it is possible to by the
Two predetermined threshold values are set as 5dBm, and preset time is set as 2s.Certainly, the second predetermined threshold value can also pass through its other party
Formula is pre-set, and is not limited in embodiments of the present invention.
Further, terminal device is when the movement speed for determining terminal device is less than or equal to 5m/s, if in 2s
The Strength Changes value of WIFI signal is more than 5dBm, then terminal device accesses the WIFI access points belonging to the WIFI signal, but by
5dBm may be less than in the next 2s changing values of WIFI signal that terminal device receives, therefore, terminal device can carry out often
Interval sampling primary 2s wouldn't need to switch to other to ensure the user using the terminal device after the WIFI has been accessed
Network.
S102, terminal device are if it is determined that movement speed is less than or equal to the first predetermined threshold value and Strength Changes value is less than or equal to
Second predetermined threshold value then accesses the WIFI access points belonging to WIFI signal.
For example, if terminal device movement speed is less than or equal to the first predetermined threshold value and Strength Changes value is less than or equal to
Second predetermined threshold value, the then access point belonging to terminal device access WIFI signal, as movement speed is less than 3m/s and first pre-
Gating limit value is 5m/s, and the pad value or yield value of signal are 1dBm, and the second predetermined threshold value is set as 5dBm, it is determined that are used
Family low-speed running in the WIFI signal overlay area of the WIFI access points, access WIFI access points will not cause high frequency to switch,
Therefore the WIFI access points belonging to terminal device access WIFI signal.

When, determine whether the movement speed of terminal device is less than or equal to the first predetermined threshold value, and determine that WIFI believes in preset time
Number Strength Changes value whether be less than or equal to the second predetermined threshold value, wherein, Strength Changes value for WIFI signal in preset time
The difference of interior maxima and minima；If movement speed is less than or equal to the first predetermined threshold value and Strength Changes value is less than or equal to second
Predetermined threshold value, then terminal device access WIFI signal belonging to access point.So, terminal device can by itself
Signal strength in movement speed and residing WIFI coverage areas judges whether to need the access point for being switched to the WIFI, need
When accessing, the operation from other network switchings access WIFI is just performed, so as to reduce unnecessary connection switching, and then is provided
Relatively stable network, and reduce power consumption caused by due to frequent switching.
Fig. 2 is the flow chart of another method for connecting network embodiment provided by the invention, and the present embodiment is with terminal device
To support to illustrate, but do not do any limit with this for the smart mobile phone of WIFI and 3G functions or support WIFI and LTE functions
It is fixed, as shown in Fig. 2, this method includes：
S201, smart mobile phone obtain the movement speed of smart mobile phone.
Further, smart mobile phone can determine whether user is in normal condition according to the movement speed of acquisition, i.e., such as
Fruit movement speed is then determined as normal condition for normal speed or so, which is the using terminal equipment of historical statistics
User is averaged the speed of travel, and smart mobile phone can perform step S202 in the case where being determined as normal condition, and smart mobile phone can not also
The judgement for carrying out normal condition directly performs S202.
S202, smart mobile phone determine whether the movement speed of smart mobile phone is less than or equal to the when detecting WIFI signal
One predetermined threshold value, and determine whether the Strength Changes value of the WIFI signal in preset time is less than or equal to the second pre-determined threshold
Value.
It should be noted that the Strength Changes value of WIFI signal has been unfolded to illustrate in the above-described embodiments, herein no longer
It repeats.
Further, if the Strength Changes value of WIFI signal is less than or equal to the second predetermined threshold value in preset time,
Step S203, i.e. smart mobile phone are then performed if it is determined that movement speed is less than or equal to the intensity of the first predetermined threshold value and WIFI signal
Changing value is less than or equal to the second predetermined threshold value, then performs step S203；If it is not, performing step S206, even movement speed is big
And/or, Strength Changes value is more than the second predetermined threshold value, then performs step S206 in the first predetermined threshold value.
It should be noted that if determine that movement speed is less than or equal to the Strength Changes of the first predetermined threshold value and WIFI signal
Value is less than or equal to the second predetermined threshold value, then it is that can be detained in the WIFI signal overlay area of WIFI access points that can determine user
For a period of time rather than the WIFI signal overlay areas of the WIFI access points is run through, so smart mobile phone accesses the WIFI
The WIFI access points of the WIFI signal overlay area of access point.First predetermined threshold value, preset time and the second pre- gating
Limit value is in the above-described embodiments for example, details are not described herein.
Further, if movement speed be more than the first predetermined threshold value and/or, Strength Changes value be more than the second pre- gating
Limit value then illustrates that the user using the smart mobile phone can speed away the area of coverage of the WIFI signal of WIFI access points detected
Domain, therefore the access point of this WIFI is not accessed, and be to continue with keeping connecting with current network.
For example, smart mobile phone may enter the overlay area of the WIFI signal of WIFI access points with soon leaving
Two time points of the overlay area of the WIFI signal of WIFI access points have detected the Strength Changes value of signal, at this time, intensity
Although changing value be less than the second predetermined threshold value, due to movement speed be more than the first predetermined threshold value, user at once just
The overlay area of the WIFI signal of WIFI access points can be left, so not accessing WIFI access points.
The user of smart mobile phone may be sitting on the vehicle at the uniform velocity travelled covering for the WIFI signal that enters the WIFI access points
Cover area, at this moment, although movement speed is 0m/s, less than the first predetermined threshold value, Strength Changes value is so large that greatly
In the second predetermined threshold value, so this time user is also the overlay area for the WIFI signal that will leave the WIFI access points,
Therefore WIFI access points are not accessed.
If the user of smart mobile phone rapid walks through or ran at a high speed the area of coverage of the WIFI signal of the WIFI access points
Domain, then in the case of most of, movement speed is greater than the first predetermined threshold value and change in signal strength value is more than second in advance
Gating limit value, at this moment, it is also the overlay area for the WIFI signal that will leave the WIFI access points that can also determine user, because
This does not access WIFI access points.
S203, smart mobile phone obtain the intensity value of the WIFI signal after variation.
Further, if smart mobile phone can be changed after WIFI signal intensity value it is relatively stable, can be with
It obtains in the short period, such as intensity value of the average value as WIFI signal of the intensity value in 30ms.If the intensity value of signal becomes
Change larger, then wait for and obtain the intensity value of the WIFI signal after stablizing again.
S204, smart mobile phone determine whether the intensity value of the WIFI signal after variation is more than or equal to third predetermined threshold value.
Further, smart mobile phone is if it is determined that the intensity value of the WIFI signal after variation is more than or equal to third pre-determined threshold
Value, then perform step S205, and smart mobile phone is if it is determined that the intensity value of the WIFI signal after variation is less than third predetermined threshold value, then
Perform step S206.
Further, third predetermined threshold value can be the minimum of the access point belonging to the WIFI signal obtained according to statistics
Access signal strength setting, such as 100dBm.
If still further, smart mobile phone simultaneously in multiple WIFI access points WIFI signal overlay area,
Using the access point belonging to WIFI signal maximum intensity or the most stable of WIFI signal of WIFI signal as target access, when in satisfaction
When stating each threshold condition, the target access is accessed.
Further, third predetermined threshold value is the access point belonging to the WIFI signal obtained according to statistics as described above
Minimum access signal strength setting, such as 100dBm, if less than this signal strength, can not also be enjoyed after smart mobile phone access
The service or service quality provided by the network is very poor, so in this case, smart mobile phone still uses original network
Connection status.
Access point belonging to S205, smart mobile phone access WIFI signal.
It should be noted that for keep connection smooth excessiveness, access WIFI signal belonging to access point during 3G or
LTE is always maintained at connection status, until access point returning response message instruction with WIFI successful connections after just will disconnect 3G or
LTE is always maintained at the connection of 3G or LIE if response message instruction and WIFI connection failures that access point returns.
S206, smart mobile phone keep current network connection state.
For example, current network connection state can be smart mobile phone and another WIFI access point connection status；
Or, it is smart mobile phone and 3G network connection status；Again alternatively, smart mobile phone and LTE network connection status.
