Accesstyrning för kommunikation i ett radiokommunikationssystem med kort räckvidd

摘要

A method and a device for access control in a radio communication system (3) with short range, for instance Bluetooth, at which a first unit (1) with a first identity (y) in said radio communication system wants to communicate with a second unit (2) with a second identity (x) in the radio communication system. The invention is characterized in the steps to transmit said first identity to said second unit; check/control access information in the second unit depending on said first identity; and to grant the first unit access for communication with the second unit over said system depending on said access information. The step to check/control access information is preceded preferably by the step to transmit (6) said access information from an access control device (4) via a secure connection on a carrier in a second communication system (5) to the second unit.
