Abstract
In a cellular radiotelephone system, the data base of a visitor location register is protected from saturation by releasing n-tuplets from the data base corresponding to those temporary mobile identity words corresponding to mobiles which announced their presence more than some predetermined time earlier, and by changing the predetermined time when the register nears saturation.
