Abstract
The present invention relates to a method of processing mobile station data in a mobile communication system in which the subscriber data of the mobile station are registered in a visitor location register which corresponds to the mobile services switching center the coverage area of which the mobile station enters, and in which the subscriber data of the mobile station are deleted from the visitor location register after it has left the coverage area. In order to avoid unnecessary deletion and re-registration of the subscriber data, the method comprises the steps of: defining an algorithm in order to determine a storage time for the subscriber data, storing in a memory information on the entries of the mobile station into the coverage area, determining the storage time with the help of the algorithm and the information stored in the memory, and after the mobile station has left the area, deleting its subscriber data from the visitor location register after the expiration of the storage time unless the mobile station has re-entered the coverage area.
