VERFAHREN UND SYSTEM ZUR PUNKTUELLEN STEUERUNG DER NETZAUSWAHL IN EINEM VON MINDESTENS ZWEI MOBILKOMMUNIKATIONSNETZEN VERSORGTEN GEBIET

The invention relates to methods and systems for selectively controlling network selection in an area covered by at least two mobile communication networks. According to the first method, the area which is to be covered is divided up into zones and a specific code is allocated to each individual zone. Said codes are stored in a storage system and the network is selected on the basis thereof. Alternately, a correlation is made between information on a subscriber identification module(SIM) and signals from a cell broadcast channel which is used to select the network.
