<p>A method of registering subscribers in a mobile communication system comprising a home location register for at least partly storing static subscriber information and dynamic subscriber information on the subscribers in the mobile communication system and at least a first visitor location register communicating with the home location register for storing the static subscriber information and the dynamic subscriber information on the subscribers registered in said visitor location register. When a registration of the subscriber is removed from the visitor location register, the visitor location register is arranged to retain the stored static subscriber information on the subscriber and to update the removal of the registration in the dynamic subscriber information on the subscriber. When the subscriber is registered, the visitor location register receives a registration message of the subscriber, checks whether the static subscriber information on the subscriber is found in the visitor location register, asks the home location register for the static subscriber information on the subscriber if the static subscriber information is found in the first visitor location register, and registers the subscriber in the visitor location register if the static subscriber information on the subscriber does not prevent the registration.</p> |
