State the second wireless control chip described second wireless network corresponding with described secondary signal intensity level and set up communication connection, pass through
Described second wireless network carries out data interaction.
Such as, terminal is accessing the first wireless network by described first wireless control chip, and by the first wireless controlled
Coremaking sheet and the first wireless network carry out data interaction, and determine that the secondary signal intensity level of at least one second wireless network is big
When the first signal strength values of the first wireless network, it is also possible to further determine that secondary signal intensity level and the first signal intensity
Whether the difference of value is more than the signal strength difference preset, and confirming that this difference is more than or equal to the signal strength difference preset
Time, terminal is communicated to connect by the second wireless network foundation that the second wireless control chip is corresponding with this secondary signal intensity level,
Data interaction is carried out by second wireless network.So it can be avoided that when message transmission rate is close, terminal frequently switches nothing
Gauze network.Wherein, the signal strength difference preset can be configured according to actual needs, does not limits.
Wherein, the quantity of the second wireless network that satisfactory secondary signal intensity level is corresponding can be one, it is possible to
Think at least two, do not limit.Satisfactory secondary signal intensity level is: secondary signal intensity level is more than the first letter
Number intensity level, and the difference of secondary signal intensity level and the first signal strength values is more than or equal to the signal strength difference preset.
When the second nothing that secondary signal intensity level satisfactory in terminal check current radio signal coverage is corresponding
When gauze network has at least two, terminal can be built with arbitrary satisfactory second wireless network by the second wireless control chip
Vertical communication connection, it is also possible to more by force or the strongest second wireless network is set up logical by the second wireless control chip and signal intensity
Letter connects.
Alternatively, step S203 may include that when at least two secondary signal intensity level is more than described first signal intensity
During value, or when at least two secondary signal intensity level is more than described first signal strength values, and secondary signal described at least two
When intensity level is more than, with the described first each self-corresponding difference of signal strength values, the signal strength difference preset, described terminal is passed through
The second wireless network foundation communication connection that second wireless control chip is maximum with secondary signal intensity level.
Such as, determine that the secondary signal intensity level of at least one second wireless network is more than the first wireless network when terminal
During the first signal strength values, it is also possible to determine that at least two secondary signal intensity level and the first signal strength values are each the most respectively
Whether self-corresponding difference is more than or equal to the signal strength difference preset.Wherein, the signal strength difference preset can be according to reality
Border needs to be configured, and does not limits.
Terminal confirm this difference more than or equal to preset signal strength difference time, by the second wireless control chip with
The second wireless network that this secondary signal intensity level is corresponding sets up communication connection, carries out data interaction by second wireless network,
So it can be avoided that when message transmission rate is close, terminal frequently switches wireless network.
Wherein, when secondary signal intensity level satisfactory in terminal check current radio signal coverage corresponding
When two wireless networks have at least two, terminal is built by the second wireless network that the second wireless control chip and signal intensity are the strongest
Vertical communication connection.
Satisfactory secondary signal intensity level refers to: at least two secondary signal intensity level is more than the first signal intensity
Value；Or at least two secondary signal intensity level is more than the first signal strength values, and at least two secondary signal intensity level and first
The each self-corresponding difference of signal strength values is more than or equal to the signal strength difference preset.
