Abstract
In order to improve the subscribing of telecommunication devices at cooperating stations connectable to the telecommunication devices by wireless telecommunication in wireless telecommunication systems, particularly DECT mobile parts at DECT base stations in DECT systems, all base stations transmitting received radio messages that have set and transmitted the “a44” bit are stored as in the mobile part, and a known log on procedure is implemented with a base station selected according to predetermined reception criteria. When this log on procedure miscarries, then this base station is marked as “invalid” and the same procedure, including the log on procedure, is implemented with a different base station. What is thereby utilized is that, in the log on, a PIN word and/or an AC word is interrogated. When the PIN word/AC word is incorrect, then the log on attempt is rejected. Otherwise, when the PIN word/AC word is correct, the mobile part has been successfully logged on at the base station.
