PROCESSING SIGNALLING MESSAGES IN A MOBILE COMMUNICATION SYSTEM

The invention relates to a mobile communication system and a method of processing signalling messages (210, 211, 212) in a mobile communication system comprising mobile stations (x, y) and base stations (1-6) the receiver units of the base stations being tuned to the same channel, in which method more than one mobile station (x, y) transmits a signalling message (210, 211, 212) to the base stations (1-6) on the same channel in such a way that said signalling messages (210, 211, 212) are received at the base stations (1-6) 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 (210, 211, 212) are stored in a memory means, an examination is conducted on whether said signalling message transmitted by a mobile station (x) has been received in several similar versions (210, 211), and if it has been, one (210) of the signalling messages of that mobile station is selected for further examination, an examination is conducted on which mobile station (x, y) has transmitted the most urgent signalling message (210) received at least partly simultaneously with the other signalling messages (210, 212), and an operation is performed on the basis of the information included in said most urgent signalling message (210). L'invention concerne un système de télécommunications mobile et un procédé de traitement de messages de signalisation (210, 211, 212) dans un système de télécommunications mobile comprenant des stations mobiles (x, y) et des stations de base (1-6), les unités réceptrices des stations de base étant accordées sur le même canal. Dans le procédé de l'invention, plus d'une station mobile (x, y) transmet un message de signalisation (210, 211, 212) aux stations de base (1-6) sur le même canal, de manière que lesdits messages de signalisation (210, 211, 212) sont reçus au niveau des stations de base (1-6), de manière qu'ils se chevauchent au moins partiellement dans le temps. Afin d'utiliser les messages de signalisation reçus au niveau des stations de base, de manière qu'ils se chevauchent au moins partiellement dans le temps, ces messages de signalisation (210, 211, 212) sont stockés dans une mémoire, un test est effectué afin de déterminer si ledit message de signalisation transmis par une station mobile (x) a été reçu en plusieurs versions similaires (210, 211), et si tel est le cas, un message (210) desdits messages
