Abstract: To transmit service data in telecommunication systems with wireless telecommunication based on a predefined radio interface protocol between telecommunication devices, especially voice data and/or packet data in DECT systems, with enhanced utilization of the bandwith of the telecommunication system and at a greater transmission rate, service data units to be transmitted are transported by radio cascaded (a cascade arrangement) in protocol data units adapted to the radio interface protocol. The protocol data units in each case contain as many information fields; configured especially as length indicators for specifying the respective service data length; as there are service data units or fragments of service data units contained in the respective protocol data unit. In addition, each information field contains an extension (a reference) in the form of a concatenated list whether further service data units or further fragments of service data units follow in the respective protocol data unit.

Abstract: To control the change, necessitated by the transmission of system information in the local information transmission loop, from a telecommunication channel—e.g. the Cf channel defined in the DECT standard—to a telecommunication channel—e.g. the Cs channel defined in the DECT standard, in a telecommunication subsystem which is tied into a telecommunication system as local information transmission loop—particularly a DECT-specific RLL/WLL subsystem tied into an ISDN system, the changing of channels is preferably initiated and performed by a time-limited interruption of the transmission of information in the telecommunication subsystem and subsequent resumption of the transmission of information.

Abstract: In order to re-log cordless mobile parts on at cordless base stations of universal mobile telecommunication systems, particularly DECT mobile parts at DECT base stations of CAP-specific telecommunication systems, without great outlay the stored, logon-specific data resulting from a preceding logon is copied. The copied data is subsequently at least partly processed. The copied, at least partly processed data is stored as re-logon-specific data.

Abstract: In a hybrid telecommunication system, a varying volume of data is transmitted between message transmission planes of telecommunication interfaces of the hybrid telecommunication system, each case it is transmitted with the least transmission complexity in the message transmission planes and, in a singe coherent data block particularly when the varying volume of data exceeds a volume of data that can be maximally transmitted between identical message transmission planes of the telecommunication interfaces. A transmission plane-specific information element in dependence on the varying volume of data at least twice, one behind the other, is used for the transmission of the volume of data in the data block.

Abstract: In order to be able to control the setting up of telecommunication connections efficiently and reliably in telecommunication subsystems serving as local message transmission loops of telecomunication systems and having network terminations which differ with regard to the transmission channel requirements, a first network termination specifies explicitly, for example in the form of a parameter, the requested transmission channel desired by it in a connection, set-up message of the network termination to the remote station in the telecommunication subsystem.

Abstract: In wire-free telecommunications systems, in particular in a DECT-specific RLL/WLL system which is included as a local message transmission loop in an ISDM system, in order to optimize the setting up and use of transmission paths with respect to the number of transmission paths for wire-free message transmission, transmission path numbers are assigned to the transmission paths such that collisions are avoided during the setting up and use of the transmission paths (links). In this way, the resources of the radio interface are used efficiently. In addition, the complexity of the telecommunications systems and the susceptibility to faults when setting up links (setting up the transmission paths) are minimized.

Abstract: To allocate telecommunication channels of different channel capacity, e.g. the ISDN D channel and DECT channels to one another (e.g. simulation of the ISDN channel structure by the DECT channel structure) with good (economic) utilization of the bandwidth and minimum technical complexity in a hybrid telecommunication system, particularly an “ISDN DECT-specific RLL/WLL” system, a DECT-specific Cs channel and a DECT-specific Cf channel are used in dependence on the amount of information transmitted on the ISDN D channel for transmitting information in the hybrid telecommunication system.
