Abstract: A method provides first data via a pilot channel of a radio communication system with the pilot channel with the data transmitting information data on available access possibilities. To provide the first data, second data received from at least one terminal is used, with the second data referring to the access possibilities available for the at least one terminal.

Abstract: A terminal is confirmed to be authorized to operate in a communication system only when it is controlled with respect to the correctness thereof during the operation. Thus, it possible to recognize whether or not the terminal failures perform a negative action on the communication system.

Abstract: According to one aspect of the invention, in a radio communications system comprising at least one base station (BS1, BS2) provided with means for transmitting data via a communication link (BCCH; V), wherein the data is divided into a plurality of data packets and being transmitted via the communication link to at least one receiving station (UE). To reduce power consumption it is proposed that the downloading of the data packets is halted if it is determined that a data packet has not been received or a corrupted data packet has been received by the receiving station, the missing or corrupted data packet is retransmitted via the same or a different communication link at a later time.
