PCT No. PCT/FI95/00062 Sec. 371 Date Dec. 18, 1995 Sec. 102(e) Date Dec. 18, 1995 PCT Filed Feb. 13, 1995 PCT Pub. No. WO95/22871 PCT Pub. Date Aug. 24, 1995A mobile communication system and a method of processing signalling messages in a mobile communication system comprising mobile stations and base stations, the receiver units of the base stations being tuned to the same channel, in which method more than one mobile station transmits a signalling message to the base stations on the same channel in such a way that the signalling messages are received at the base stations so that they overlap at least partly in time. In order to utilize the signalling messages which are received at the base stations so that they overlap at least partly in time, these signalling messages are stored in a memory, an examination is conducted on whether the signalling message transmitted by a mobile station has been received in several similar versions, and if it has been, one of the signalling messages of that mobile station is selected for further examination, an examination is conducted on which mobile station has transmitted the most urgent signalling message received at least partly simultaneously with the other signalling messages, and an operation is performed on the basis of the information included in the most urgent signalling message.
