Abstract

In order to improve the logging in of battery-operated mobile parts (MT) in base stations (BS) with a battery charging device (ALE) in telecommunications systems for wireless telecommunication so that a log-in standby state between the mobile part (MT) which is logging in and the base station (BS) can be automatically produced without the user of the telecommunications system having to execute existing described procedures, said log-in standby for a battery operated mobile part (MT) in a base station (BS) with a battery charger in a telecommunications network for wireless telecommunication is produced by means of charging contacts (LK1-M, LK2-M, LK1-B, LK2-B) of the mobile part (MT) and base station (BS), whereupon the log-in procedure is carried out via the aerial interface of the telecommunications system.

the registration of the mobile part (MT) at the base station (BS), if this is ready for registration—

is undertaken by wireless telecommunications, in which case prespecified registration data, especially base station, mobile part, system and product-specific identifications, are transmitted between the mobile part (MT) and the base station (BS) and stored in the memory (SP-M, SP-B),
