Abstract

A method of operating a mobile wireless network is described to ensure proper function of protocol entities during the transmission of data units between two wireless stations of the mobile wireless network. In this case, 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, in order to form the at least one first data unit from the data received from the at least one user and to transmit it through a carrier to a link control layer.

specifying at least one compression algorithm for compressing one of protocol control data for the transmission of the at least one first data unit and the user data, the at least one compression algorithm corresponding to a decompression algorithm in the second wireless station for decompressing one of the protocol control data and the user data.

5. The method according to claim 4, wherein the specifying step includes the substep of:

specifying at least one compression parameter along with the specification of the at least one compression algorithm, the compression parameter also being used for decompression in the second wireless station.

6. The method according to claim 5, wherein the at least one compression parameter includes a number of codes to be stored for the compression.

9. The method according to claim 1, wherein the configuring step includes the substep of:

specifying the carrier.

10. The method according to claim 1, wherein the configuring step includes the substep of:

specifying, using the configuration request, at least one selection of alternative settings for the at least one protocol entity that are supported by the second wireless station.

11. The method according to claim 10, further comprising the steps of:

selecting a setting from the at least one selection of alternative settings by the first wireless station;

performing the selected setting by the first wireless station; and

communicating the selected and performed setting to the second wireless station by transmitting a confirmation signal from the first wireless station to the second wireless station.

12. The method according to claim 1, further comprising the step of:

permanently specifying at least one setting for the at least one protocol entity using the configuration request.

13. The method according to claim 1, wherein the protocol entity ID is specified so that it corresponds with an ID of the carrier assigned to it.

14. The method according to claim 1, further comprising the step of:

transmitting a communication from the first wireless station to the second wireless station, before receipt of the configuration request, to indicate settings of the at least one protocol entity that are supported by the first wireless station.

15. The method according to claim 14, wherein the communication is transmitted to the second wireless station together with a message about capabilities and an output range of the first wireless station.
