Abstract (en)
[origin: WO9962222A2] The invention relates to a method for safe telephony with mobility in a tele and data communications system (1) which includes an IP-network (15), at which the telephony is executed with mobile units and at which the method for each mobile unit includes the steps: to create a unique identity code and store it in the unit; to, at the switching on of the unit, at least at switching it on in a home domain, transmit the identity code to a mobility manager (9); to, via the IP-network, establish contact between the mobility manager and an initiating database (13) for transmission of initiating information for Internet communication from the initiating data base to the mobility manager, which step includes to, by utilisation of the identity code, authenticate the mobility manager for access to the initiating data base, and to encrypt the initiating information at the transmission; and to, by means of the initiating information, start a proxy (11) which represents the unit towards the Internet.
