An ATM network, adapted to support mobility of Mobile Terminals (MT) at ATM end points includes: a number of mobile terminals; a core network of ATM switches; mobility management means including a Location server (LS); at least one mobility enhanced ATM switch (MAS) having an Access Point (AP) for providing radio connectivity between MT and network; and at least one ATM Roaming Server (RS). The RS is, e.g., an ATM switch having a location server associated therewith, for handling location updates for roaming MTs, or mobility in the ATM network. Thereby reduction in the signalling load on the MT's home network is effected. The ATM RS includes a database for storing a network address for the LS, mappings between network addresses and temporary adresses for each MT, and an address of an authentication server. The database is updated when the MT first moves to and registers with, another network. |
