Abstract:
1. A method for coupling a mobile terminal with an adapter, the method comprising at least the following steps: coupling the mobile terminal with the adapter by RF induction; decreasing transmitted power of the mobile terminal so that RF power leaking around is maintained below a specified value when the mobile terminal detects that it has been coupled with the adapter; and controlling a gain of the adapter by the mobile terminal, so that the transmitted power from an antenna of the adapter can reach a due power level transmitted by the mobile terminal before the mobile terminal is coupled with the adapter wherein in order that the RF power leaking around is maintained below the specified value, the mobile terminal whose transmitting power is between 5th and 9th grade in GSM or between zero and 3rd grade in DCS decreases its transmitting power by 10 dB, a power loss due to the coupling by RF induction being assumed to be 10 dB, then the mobile terminal controls a higher gain 20 dB increased by an amplifying means of the adapter to compensate the transmitting power decreased by the mobile terminal itself and the power loss due to the coupling.
