Abstract

A process provides access data to a transportable subscriber station, for establishing access to a service provider station. A first access mode which can be provided using first access data includes a first network that is accessible by means of a selectable network account, a first switching station, and a second network. A second access mode can be provided by means of second access data by way of the first network and a fixedly defined second switching station. If first access data for the selected network account are not available a request for the second access mode is made to the service provider station, using the stored second access data, and a request is made for first access data for the selected network account in the second access mode. This requested access data for the selected network account are transmitted to the subscriber station in the second access mode and stored for the selected network account in the subscriber station.
