An infrastructure and method for controlling wireless access to a telecommunications infrastructure for a device includes a first access grant time interval applicable for granting access for the device to the telecommunications infrastructure stored in a device register system. The first access grant time interval is applied when the device requests access to the telecommunications infrastructure via a first network node of the telecommunications infrastructure. However, a second access grant time interval is applied in a second network node of the telecommunications infrastructure when the device requests access via the second network node. The second access grant time interval is applicable for granting access for the device to the telecommunications infrastructure and is different from the first access grant time interval.
