Abstract

System and method for the registration of a mobile part (MT, OA, HA) in a base station (BS) in a telecommunication system designed for wireless communication between a mobile part (MT, OA, HA) and a base station (BS. The base station and the mobile part are initially placed in an access standby state. Subsequently, a verification procedure determines a message exchange (MA) between the mobile part and the base station if the base station supports a voice-controlled registration and if the mobile part is theoretically connected to the base station. If the theoretical connection is determined, a user channel connection suitable for the transmission of voice data is established between the mobile part and the base station. The mobile part is then either registered in the base station, or the registration attempt is rejected.
