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.

Claims

a network unit, which offers services for subscribers in the mobile wireless network and operates the mobile wireless network;

a first wireless station, which is a mobile wireless station; and

a second wireless station, which is a base wireless station connected to the network unit;

wherein the network unit is configured to perform the following;

configure at least one protocol entity of a first convergence protocol layer of the first wireless station as a function of a configuration request received from the second wireless station, wherein the configuring includes specifying multiplexing properties to define at least one user, and wherein data units of the at least one user are assembled by the at least one protocol entity from the respective received user data before transmitting, in a multiplexed manner, to a link control layer via a carrier,

supply user data to the first convergence protocol layer by the at least one user in a network layer,

assemble the user data into at least one first data unit by the at least one protocol entity of the first convergence protocol layer, wherein the at least one first data unit is assembled before a transmission to a second convergence protocol layer of the second wireless station, and

transmit the at least one first data unit to the link control layer via the carrier; and

wherein a communication indicating which settings of the at least one protocol entity are supported by the first wireless station before receiving the configuration request from the second wireless station is transmitted from the first wireless station to the second wireless station.

2. The radio telecommunication system of claim 1, wherein the configuring includes:

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, wherein the at least one compression algorithm corresponds to a decompression algorithm in the second wireless station for decompressing one of protocol control data and user data.

3. The radio telecommunication system of claim 2, wherein the specifying includes:

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

4. The radio telecommunication system of claim 1, wherein the carrier, via which the user data are transmitted from the protocol entity to the link control layer, is set up, and wherein at least one selection of alternative settings for the protocol entity that are supported by the second wireless station is specified using the configuration request.

5. The radio telecommunication system according claim 1, wherein the carrier, via which the user data are transmitted from the protocol entity to the link control layer, is set up.

6. The radio telecommunication system of claim 1, wherein at least one selection of alternative settings for the protocol entity that are supported by the second wireless station is specified using the configuration request.

7. The radio telecommunication system of claim 6, wherein a confirmation signal, in which the setting selected and performed by the first wireless station is communicated, is transmitted from the first wireless station to the second wireless station.

8. The radio telecommunication system of claim 1, wherein at least one setting for the at least one protocol entity using the configuration request is permanently specified.

9. The radio telecommunication system of claim 1, wherein the configuring includes:

specifying a protocol entity identity (ID), through which the protocol entity is referenceable, during the configuration.

10. The radio telecommunication system of claim 9, wherein the protocol entity ID is specified, so that it corresponds to an ID of the carrier assigned to it.

11. The radio telecommunication system of claim 1, wherein the communication is transmitted to the second wireless station together with a message about the capabilities and the output range of the first wireless station.

12. The radio telecommunication system of claim 1, wherein the at least one protocol entity using the configuration request is established.

13. The radio telecommunication system of claim 12, wherein settings of the established at least one protocol entity using the configuration request are modified and reconfigured.

15. The radio telecommunication system of claim 7, wherein the configuration request is inserted into a carrier configuration message for the case in which the carrier is established, reconfigured and released by using the carrier configuration message.

16. The radio telecommunication system of claim 15, wherein one of the establishment and the reconfiguration of the carrier by inserting a confirmation signal into a message is acknowledged by the first wireless station.

17.
