Block includes:
First data transmission speed obtains submodule, if having in the accessible WLAN got
There is multiple signal intensity WLAN more than described preset first threshold value, then obtain the plurality of signal intensity
Data transmission bauds more than the WLAN of described preset first threshold value；
First object WLAN determines submodule, for being preset more than described by the plurality of signal intensity
In the WLAN of first threshold, the fastest WLAN of transmission speed is defined as first object WLAN；
First object WLAN switching submodule, is used for switching to described first object WLAN.
12. devices according to claim 11, it is characterised in that also include:
3rd signal intensity acquisition module, if the data network for being currently accessed is mobile network, and
Described currently accessible WLAN does not have signal intensity more than described preset first threshold value
WLAN, obtains the signal intensity of current mobile network the most in real time；
Target WLAN determines module, if the signal intensity for current mobile network is less than default second
Threshold value, then determine the second target WLAN in described currently accessible WLAN；
3rd network handover module, is switched to described second target WLAN.
13. devices according to claim 12, it is characterised in that described target WLAN determines
Module includes:
Presupposed information extracts submodule, is used for extracting and presets acquiescence WLAN information；
Second target WLAN determines submodule, for by corresponding for described default acquiescence WLAN information
WLAN, is defined as the second target WLAN.
14. devices according to claim 12, it is characterised in that described target WLAN determines
Module includes:
Second data transmission bauds obtains submodule, for obtaining described currently accessible WLAN's
Data transmission bauds；
3rd target WLAN determines submodule, for by described currently accessible WLAN, passing
Defeated fastest WLAN is defined as the second target WLAN.
