ABSTRACT:
In a speed dialing method for a telephone unit, a dialed telephone number is automatically stored in a speed dialing memory. The memory is automatically sorted at each call, the telephone numbers always being in an order determined by their dialing frequency, with the most frequently dialed number at the top. By pressing step/skip buttons, the caller can scan such an adaptable memory. The method is applied in mobile telephones, in particular car radiophones.
