Abstract

A device for controlling a service access authorization for a user device with regard to an access-restricted service includes a service access authorization provider, the service access authorization provider being configured to set a period of time in which the service access authorization is valid, responsive to an authorization message provided with a service-dependent user identifier, and the service access authorization provider being configured to disable an authorization allowing the service access authorization to be extended or reactivated using the previous service-dependent user identifier when at least a predetermined duration has passed since an end of a last authorization time interval for which a service access authorization was determined by the device.
