On the contrary, if be sure " YES " in the judged result of step S1, if promptly received any one incoming call signal, program advances to step S7, at step S7, carries out the incoming call Signal Processing.Then program advances to step S8, carries out a judgement at step S8, judges whether the user has answered the incoming call signal, and promptly whether the user has picked up subscriber unit so that phone breaks away from relaying from the modulation station.If the judged result at step S8 is " YES ", if promptly the user has taken out subscriber unit from the modulation station, then program advances to step S9, and at step S9, communicator is placed in " TALK MODE " state.
On the other hand, if be " NO ", if promptly subscriber unit still is retained in the modulation station in the judged result of step S8, program advances to step S10, in this step, communicator is placed stand-by state again, to wait for any one incoming call signal.Therefore, carry out a judgement, judged whether that any one incoming call signal has been offered subscriber unit from base station at step S10.
If the judged result at step S10 is " YES ", if promptly received an incoming call signal, program turns back to step S8, carries out a judgement once more in this step, judges whether the user has answered the incoming call signal.On the other hand, if be " NO ", if promptly do not receive the incoming call signal in the judged result of step S10, program advances to step S11, and in this step, shake bell device is compelled to stop, to interrupt radio communication line, the what is called of promptly carrying out after the incoming call signal returned is handled.After this, program turns back to step S1, and at this step S1, communicator is in stand-by state once more, to wait for any one incoming call signal.
