The method of random access comprises the selecting (112; 140) of an available uplink access slot; the transmission (136) of a preamble with a commanded power (CPP); the evaluation (138, 162) of the satisfaction of a send authorization criterion (AI) following the transmission of said preamble; and the transmission (164) of a message part when said send authorization criterion (AI) is satisfied. It comprises, after said step (112; 140) of selecting an available uplink access slot, the detecting (116; 142) of a possible overlap between said selected available uplink access slot and a measurement occasion and in case of detection of an overlap, the selecting (112; 140) of a new available uplink access slot. Application to a mobile station of a UMTS network.
-Method of random access to a physical random access channel (PRACH) of an uplink (18) associated with a downlink (16), for carrying out a random access transmission comprising the sending of at least one preamble and of a message part comprising the steps of:
Method according to any of the preceding claims, characterized in that said step (116;
-Method according to any of the preceding claims, characterized in that it comprises a step of calculating a cyclic ratio of the measurement occasions which is dependent on the duration of the measurement occasions which is used over a predetermined duration, and in that said step (112;
-Mobile station suitable for sending a random access transmission comprising at least one preamble and a message part by random access over a physical random access channel (PRACH) of an uplink associated with a downlink comprising:
