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.

Method and device for selectively controlling network selection in an area covered by at least two mobile communication networks

The invention pertains to a method for reaching subscribers in a radio communication system in which an object identification is temporarily assigned to the subscribers. The temporary object identifications are formed by subscriber data sets that respectively define a complete subscriber environment of a virtual communication network VP within the radio communication system, wherein one or more of such subscriber data sets can be assigned to subscribers of the communication system.
