PCT No. PCT/FI93/00420 Sec. 371 Date Jun. 20, 1994 Sec. 102(e) Date Jun. 20, 1994 PCT Filed Oct. 14, 1993 PCT Pub. No. WO94/09597 PCT Pub. Date Apr. 28, 1994.A random access method in a radio system having a plurality of radio stations and at least one base station serving the radio stations, in which the base station transmits an invoking message to the radio stations in a first time slot to grant the radio stations the right to send a random access message to the base station. One of the radio stations transmits a random access message containing a random identifier to the base station in a second time slot subsequent to the first time slot. The base station transmits a response message containing the random identifier to the radio station in a third time slot subsequent to the second time slot. In order to avoid allocating the same telecommunications resource for simultaneous use by more than one of the radio stations, the response message sent by the base station to the radio station in the third time slot contains the identifier of the second time slot. |
