Abstract

The present invention in particular relates to a method for initializing and/or activating at least one user account and/or a user identifier with at least one service provider by means of a first communications network, in particular a mobile network, whereby the user account and/or the user identifier has validity in at least one other second communications network that is independent of the first communications network. In order to be able to utilize transaction systems based on mobile networks, particularly in a simple and inexpensive manner also in situations outside the mobile sector, for example in WLAN via DSL situations, the method is characterized by the following steps: a) a request for initializing and/or activating the user account and/or the user identifier is generated by the user via a terminal device assigned to the first communications network and transmitted via a communication channel of the first communications network from the terminal device of the user to the service provider, in particular at least partially encrypted; b) during the transmission, an identifier characterizing the user and/or the terminal device of the user is assigned to the request on the part of the first communications network; c) after receiving the request with the added identifier, at least one user identifier that is independent of the communications network is generated on the part of the service provider; d) the generated user identifier is transmitted by the service provider to the terminal device of the user, in particular at least partially encrypted, and stored in this device.
