Abstract
A method and an arrangement for detecting the misuse of the call forwarding service in a mobile communication system. In the invention, call forwarding is activated for routing a call addressed to a mobile subscriber to a forwarding number supplied by the mobile subscriber; the forwarding number is modified by registering call forwarding to another number; the number of call forwarding registrations is counted subscriber-specifically; and an alarm is generated when the number of call forwarding registrations exceeds a predetermined maximum value during a predetermined period of time.
