The base station includes a signal controlling unit, a signal communicating unit and a signal storage unit. The signal controlling unit is electronically connected to the signal communicating unit and the signal storage unit. The calling terminal sets call displaying images, and the call displaying images are sent to the signal communicating unit under the control of the signal controlling unit.
