1. A radio communication system with a base radio station and mobile radio stations, which in existing radio links continuously individually realise and maintain synchronism on the basis of received frame synchronization blocks, wherein the base radio station is capable of continuously transmitting radio messages, for example, data blocks containing signalling information, on a transmission channel in a changeable pattern of time frames, wherein, for permanently monitoring the radio link, the mobile radio stations are capable of monitoring the reception of radio messages in this pattern of time frames, wherein the mobile radio stations are capable of resetting a counter when valid radio messages are received and wherein, when invalid radio messages are received, the mobile radio stations are capable of incrementing the count of the counter, this count representing a criterion for the quality of the radio link. |
