CONCEPT OF EFFICIENTLY DISTRIBUTING ACCESS AUTHORIZATION INFORMATION

摘要

The invention relates to a device (100) for controlling service access authorisation for a user device in relation to an access restricted service. Said device comprises a service authorisation access provider (101) that is designed to control, corresponding to an authorisation message (103) provided with a service-dependent user identification (102), a period of time during which the service authorisation access (104) is present exists and to deactivate (105) authorisation that allows the service authorisation access (104) to be extended or reactivated using the previous service-dependent user identification (102), if at least one predetermined duration (123) has elapsed since the end of the last authorised time interval (106) for which one service authorisation access (104) was determined by the device (100).
