Abstract
Abstract The invention relates to a method of controlling subscriber registrations in a mobile communication system where subscriber data concerning visiting subscribers is temporarily stored in a visitor location register. The mobile subscribers are divided into subscriber groups, and subscriber registration quotas, i.e. a limited percentage of the total registration capacity is allocated to each of the subscriber groups by the operator. The visitor location register is arranged to count the number of registered subscribers in each group, and to reject further registrations in the subscriber group if the subscriber registration quota allocated to the respective subscriber group is occupied.
