Abstract: A method of assigning transmission channels in a telecommunications network and a user station are provided, which facilitate an increase in the capacity of a telecommunications network. The telecommunications network may include multiple base stations and mobile stations, the transmission channels being provided for transmitting signals between the base stations and the mobile stations. In uncoordinated operation of the base stations, at least one of the transmission channels is assigned for transmitting signals between one of the base stations and one of the mobile stations as a function of a channel measurement, in which the transmission power on all possible transmission channels is measured, if the previously measured transmission power on this transmission channel is minimal.

Abstract: A method for transmitting short messages (5) in a telecommunications network (10) is proposed, which enables especially simple, convenient downloading of data fields (15, 20, 25, 30) of the short message (5) from a network operator (70). A notice is sent to a subscriber (60) of the telecommunications network (10) as a function of a short message (5) transmitted to the telecommunications network (10) for the subscriber (60). With the notice, data that include items of information about the makeup and/or content of the short message (5) are transmitted to the subscriber (60).
