D. if the index signal of step B is expression " closing ", then turn off the wireless radiofrequency transceiving chip immediately and continue to close main control integrated circuit, make radio-frequency SIM card be operated in little current-mode, stop waking operating state up, wait for the arrival of timing wake-up clock pulse Pwd next time simultaneously; Return steps A.
Described radio-frequency SIM card comprises wireless radiofrequency transceiving chip, interface treatment circuit and main control integrated circuit, and described radio-frequency SIM card is arranged in the portable terminal, communicates by letter with supporting peripheral unit by the wireless radiofrequency transceiving chip.
" looking different situations " described in the step B and be meant the wireless radiofrequency transceiving chip judges by the frequency or the data characteristics that detect the peripheral unit signal, whether this peripheral unit is communicating by letter with described radio-frequency SIM card or not communication and need to stop waking up at once operating state, thus the control radio-frequency SIM card wake operating time Twd up.
The peripheral unit that described step B and C relate to comprises radio-frequency card reader.
The signal that described peripheral unit sends when communicating by letter with described radio-frequency SIM card belongs to self-defined characteristic signal, comprises arbitrary characteristics sequence, arbitrary characteristics sign indicating number or analog signal.
Compare with prior art, beneficial effect of the present invention is:
1, radio-frequency SIM card and radio frequency hand-held device, its most of the time all is operated in standby (dormancy) pattern, can prolong total standby (dormancy) duration relatively;
2, needn't change the wakeup frequency of radio-frequency SIM card and radio frequency hand-held device, total standby (dormancy) duration is increased, thereby reduce the number of times of described device charging, the life-span of described device battery is prolonged.
