摘要

A method and a device for access control, whereby a control unit (13) is operatively connected with a memory (14) for storage of authorized identification numbers for current service or access in a register. The control unit (13) is operatively connected with a telephone unit (12) for reception of an identification number of a calling party by means of a telephone connection made by wireless telephony from a remote control unit (11). The control unit (13) is designed to compare the received identification number with the stored identification numbers without answering the telephone connection, and to emit a signal to accept authorization if the received identification number is in agreement with an identification number stored in the register.
