Method for anonymous use of a radio communications system

The invention relates to a method for using a communication system with a data transmission system, in particular a mobile network, by individual participants for the transmission of information to at least one recipient, in which an access identifier is required as a user authorization for the use of services of the communication system. Nevertheless, in order to maintain a complete anonymity of each individual subscriber to the recipient, it is proposed that a group identifier, which prevents a passing on of the access identifier, is assigned to a group of subscribers and transmitted as part of the data. In addition, during each information transmission to the receiver, a constant individual identifier is transmitted for at least a period of time,
