The recipient judges that according to the performance parameter of first request signal and second answer signal distance between transmit leg and the recipient is whether in preset range, transmit leg judges that according to the performance parameter of first answer signal and second request signal distance between transmit leg and the recipient is whether in preset range, when judging in preset range, communicating pair is set up radio communication and is connected.
10. portable terminal method for transmitting signals as claimed in claim 7 is characterized in that, described transmit leg arranges and sends first coil of frequency by transmit leg the processing procedure that first magnetic signal sends to the recipient is specifically comprised:
Sender-selected magnetic signal sending function is closed the magnetic signal receiving function, at first coil of the 3rd frequency by transmit leg first magnetic signal is sent to the recipient, when magnetic number sends the back unlatching magnetic signal receiving function that finishes;
Described recipient specifically comprises in the processing procedure that second coil of the 3rd frequency by the recipient receives first magnetic signal:
The recipient selects the magnetic signal receiving function, and at the 3rd frequency, second coil by the recipient receives first magnetic signal;
The recipient selects the magnetic sending function, closes the magnetic signal receiving function of self, at first coil of the 3rd frequency by the recipient second magnetic signal is sent to transmit leg, sends the magnetic signal receiving function of the back unlatching self that finishes when magnetic signal;
Sender-selected magnetic signal receiving function receives second magnetic signal at second coil of the 3rd frequency by transmit leg;
The recipient judges distance between transmit leg and the recipient whether within preset range according to the performance parameter of described first magnetic signal, and when judging in preset range, communicating pair is set up the processing procedure that radio communication connects and specifically comprised:
The recipient judges that according to the performance parameter of first magnetic signal distance between transmit leg and the recipient is whether in preset range, transmit leg judges that according to the performance parameter of second magnetic signal distance between transmit leg and the recipient is whether in preset range, when judging in preset range, communicating pair is set up radio communication and is connected.
11. as each described portable terminal method for transmitting signals of claim 7-10, it is characterized in that, magnetic signal to be sent among transmission one side also carries this side's identity identification information, the opposing party receives described magnetic signal, earlier judge distance between the communicating pair whether in preset range by the intensity of described magnetic signal, the identity identification information to entrained sender carries out authentication then, when judgement in preset range, and after the authentication success, communicating pair is set up radio communication and is connected.
