Abstract

A mobile station, as well as a method and communication system for adapting same, is provided. The mobile station is located in a radio coverage area of a mobile radiotelephone network and generates an adaptation to a radio interface access method of the mobile radiotelephone network based on signaling information that is transmitted on a pilot channel. The pilot channel is sent by at least one broadcast transmitting station of a public broadcast system in the radio coverage area of the mobile radiotelephone network and received and evaluated by the mobile station.
