<p>The invention relates to a random access method in a radio system comprising a plurality of radio stations (RS1, RS2, RS3, RS4, RS5, RS6) and at least one base station (BS) serving said radio stations, in which method the base station (BS) transmits an invoking message (HPK) to the radio stations (RS1, RS2, RS3, RS4, RS5, RS6) in a first time slot to grant the radio stations (RS1, RS2, RS3, RS4, RS5, RS6) the right to send a random access message (HP) to the base station (BS), one of the radio stations (RS1) transmits a random access message HP(S1) containing a random identifier (S1) to the base station (BS) in a second time slot (A1) subsequent to the first time slot, the base station (BS) transmits a response message V(S1, TT7, A1) containing the random identifier (S1) to said radio station (RS1) in a third time slot (A6) subsequent to the second time slot. In order that the problem which is caused if the same telecommunications resource is allocated to several radio stations could be avoided, the response message V(S1, TT7, A1) sent by the base station (BS) to said radio station (RS1) in the third time slot contains the identifier (A1) of said second time slot (A1).</p> |
