Abstract: A system and method for the management of telecommunication system subscriber data in conjunction with at least two duplex telecommunication networks handling separate subscriber data. The inventive system includes means for linking the system, in a transparent manner with respect to telecommunication network architecture, to telecommunication network elements handling subscriber data, means for storing the subscriber data of different telecommunication networks in the same logical database, and means for exchanging subscriber data between the telecommunication network elements handling subscriber data and/or the subscriber database. The system may for example be used to implement a subscriber accessibility service between and operable across different networks.
