Abstract: The invention relates to a device for processing datastreams in a communications unit with two mutually-separate data-processing regions, which provide at least two separate message paths. The message paths are connected respectively to a message transmitter and a message receiver, wherein, in each message path, an encoding module is provided, which is connected both to a first data-processing region and also to a second data-processing region. Furthermore, in the second data-processing region, a distribution unit is provided, which is connected to the message paths of the first data-processing region and to all encoding modules of the corresponding message paths in order to distribute given messages in a targeted manner.

Abstract: An approach is provided for operating a radio network, wherein the operating frequency is varied systematically according to an enciphered sudden-frequency-change scheme and retained only during a hop. Several hops are combined to form a service interval, a service window being arranged at a variable position within the service interval. Given hops for different functionalities (late traffic entry, break-in, hailing, late network entry) of the radio network are specified in the service window.
