Abstract

See full text

A communications system, in particular a telephone system, is provided for the connection of mobile subscriber terminal devices via radio links, in which a central and/or sub-central location there are arranged storage devices which, for all of the users, each store an item of information concerning the relevant location of a user. The particular stored item of location information is used to control the switch-through of a connection to be established to the mobile user. The subscriber terminal devices include identification read-out devices for reading user identification cards. The subscriber terminal device temporarily receives the user call code stored on the user identification card which provides the facility of passive access to the user. Facilities are also provided for automatic charge accounting.
