Abstract
A method for disseminating value-added information is described, starting from known radio paging services in which on one or more frequencies, by means of an address code which establishes the identity of a certain receiver, a message can be transmitted to the receiver, wherein at least one second standard address code is provided for identifying several receivers of the radio paging service, which is transmitted on one or more frequencies used by the radio paging service. By setting up a second address code, several subscribers to a radio paging service can be addressed simultaneously. The subscribers can in this case select and call up desired value-added information.
