Abstract: A method for the geolocalization of a base station, referred to as the “sought base station”, of an access network of a wireless communication system. The wireless communication system also includes at least one terminal capable of transmitting messages bound for the access network. A message transmitted by a terminal can be received simultaneously by a plurality of base stations of the access network. The geographical position of the sought base station is determined as a function of the geographical position of at least one other base station of the access network, referred to as the “reference base station.” The geographical position of the reference base station is known. The reference base station having received a message transmitted by the terminal that has likewise been received by the sought base station.

Abstract: A method of transmitting, by a terminal of a wireless communication system, a message on a communication channel shared with other terminals. Before sending the message, the terminal listens on the communication channel until the terminal detects an absence of activity on the communication channel for an inactivity time ?Tin. When no activity is detected on the communication channel for the inactivity time ?Tin, the terminal waits for a waiting time ?Tat and then transmits the message on the communication channel. The waiting time ?Tat is identical for all of the terminals of the wireless communication system.
