Mobile radio receiver for cellular radio telecommunications systems

The invention relates to a mobile radio receiver for cellular radio telecommunications systems according to the precharacterizing clause of patent claim 1. 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, 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.
