8. mobile terminal signal transmission method as claimed in claim 7, it is characterised in that described
Recipient judges the distance between sender and recipient according to the performance parameter of described first magnetic signal
Whether within preset range, when judging in preset range, open radio frequency communications unit, and examine
Survey whether sender opens radio frequency communications unit, the most then communicating pair sets up radio communication connection tool
Body includes:
The intensity level of more described first magnetic signal of described recipient and the first distance threshold preset, root
Judge whether described recipient enters the efficient communication of default recipient and sender according to result of the comparison
Distance is interval；The intensity level of more described second magnetic signal of described sender and the second distance threshold preset
According to result of the comparison, value, judges whether sender enters default recipient and lead to the effective of sender
Communication distance is interval；When described recipient enters the effective communication distance district of default recipient and sender
Between, and described sender is interval with the effective communication distance of sender also into default recipient,
Communicating pair sets up radio communication.
9. as claimed in claim 7 mobile terminal signal transmission method, it is characterised in that described in connect
According to the performance parameter of described first magnetic signal, debit judges that the distance between sender and recipient is
No within preset range, when judging in preset range, open radio frequency communications unit, and detect
Whether sender opens radio frequency communications unit, the most then communicating pair sets up the place that radio communication connects
Reason process specifically includes:
Described sender compares the intensity level of the second request signal and the first answer signal and self presets
Communication distance threshold value；Described recipient compare the first request signal and the second answer signal intensity level and
The communication distance threshold value that self presets；When communicating pair is all in preset range, set up radio communication even
Connect.
10. mobile terminal signal transmission method as claimed in claim 7, it is characterised in that receive
Whether root judges the distance between sender and recipient according to the performance parameter of described first magnetic signal
Within preset range, when judging in preset range, open radio frequency communications unit, and detection is sent out
Whether the side of sending opens radio frequency communications unit, the most then communicating pair sets up the process that radio communication connects
Process specifically includes:
Described recipient according to the performance parameter of the first magnetic signal judge between sender and recipient away from
Whether from preset range, sender judges sender according to the performance parameter of the second magnetic signal and connects
Whether the distance between debit is in preset range；When judging that sender and recipient are all in preset range
In, sender and recipient set up radio communication and connect.
