METHOD FOR DEREGISTERING FUNCTIONAL NUMBERS FOR MOBILE STATIONS OF A RADIO COMMUNICATION SYSTEM

摘要

The method involves implementing a comparison between a characteristic value of a Global system for mobile communications (GSM)-railway network (3) and an international code of a functional number in a GSM-railway home network (5) of a mobile network (1). The functional number is deregistered in a configuration-database (10) of another GSM-railway network (4). The deregistration of the functional number is delayed with determined difference between the characteristic value of the railway network (3) and the international code of the functional number.
