  • Publication number: 20040209623
    Abstract: In a public land mobile network comprising a base station and a plurality of mobile subscribers, each subscriber is assigned at least one of a plurality of access classes, and the base station broadcasts signalisation to all subscribers comprising selected access classes which are barred from access to the network upon receipt of the signalisation. The load condition of the network is checked in regular time periods, and the number of barred access classes is increased or decreased dependent on whether a load threshold value is exceeded or not. Each time period is divided in a plurality of sub-intervals in which a rotation of the selected access classes is made to evenly distribute the bar to access onto the plurality of subscribers.
