For mobile radio receivers (MT ) which are used in a cellular radio telecommunications system, in order to allow interruption-free relaying of a telecommunications link, in particular even if stationary radio transmitters (U-BS, H-BS) which are arranged in the cellular telecommunications system are not synchronized (asynchronous radio telecommunications system), the mobile radio receiver (MT ) has, in particular, first to third devices (FKT, SST, BMC, ZST, &mgr;P, SPGM, SWS). Using these devices, it is possible to receive all those radio messages which are transmitted for possible radio links at frequencies, in time slots and/or in channels by the radio transmitter (U-BS, H-BS) and allow radio links to be set up. In consequence, the mobile radio receiver is able to set up, in addition to a first radio link which is used as a telecommunications link, at least one second radio link, which is intended to be used as a telecommunications link, in the background.

Mobile radio receiver for cellular radio telecommunications systems

A cordless mobile part and method that detects selection features for a number operating modes. The mobile part also controls functional sequences specific to the mobile part and identifies the operating modes specific to the mobile part, the operating modes include a first operating mode for operating on a convenience charging station; a second operating mode for operating on a standard charging station; a third operating mode for operating on a headset fourth operating mode for operating as a handset. A controller connected to the detection system is designed in such a manner that interrogation is performed at all the branch points in each decision level on the basis of a selection feature in accordance with a decision tree having a plurality of decision levels and level-immanent branch points.
