FIELD: cellular telecommunication systems. SUBSTANCE: device has first to third units, which receive all radio messages that provide possibility to establish communication and are transmitted by transmitter for possible connections within frequencies, channel intervals and/or channels. This results in possibility to establish at least one second radio connection, which serves as telecommunication radio connection in parallel to first connection. EFFECT: continuous connection, in particular, when stationary transmitters of telecommunication system are not synchronized (asynchronous radio telecommunication system). 19 cl, 9 dwg
