Abstract
A method of picking up mobile stations (DMRU1 to DMRU6) onto a direct mode channel (f2) in a radio system that comprises a first (f2) and a second (f1) direct mode channel, a repeater (R1) to which the first direct mode channel (f2) is allocated, and mobile stations (DMRU1 to DMRU6). In the method, the repeater (R1) tunes to and listens to the second direct mode channel (f1) and determines the moment when it can transmit on the second direct mode channel; the repeater (R1) transmits one or more pick-up messages on the second direct mode channel; the mobile stations (DMRU4, DMRU6, DMRU7) that communicate on the second direct mode channel (f1) receive the pick-up messages; and the desired mobile stations that communicate on the second direct mode channel (f1) switch, in response to the pick-up messages, to the first direct mode channel (f2) for communication.
