Operating a mobile wireless network to ensure proper function of protocol entities during the transmission of data units between two wireless stations of the mobile wireless network. User data is assembled by a first convergence protocol layer of the first wireless station into at least one first data unit, particularly a packet data unit, before transmission to a second convergence protocol layer of a second wireless station, particularly on the same protocol level, with the user data being supplied to the first convergence protocol layer by at least one user in a network layer. At least one protocol entity of the first convergence protocol layer is configured as a function of a configuration request received by the second wireless station and transmits the at least one first data unit through a carrier to a link control layer.
