the physical layer or a higher layer wherein the monitoring entity bypasses one or more intermediate layers and directly accesses the physical layer, which provides the necessary information. ## Claims ### Claim 1 A method for monitoring the quality of a data connection, wherein the data about a radio channel subject to interference in a cell of a transmission network are transmitted to at least one mobile subscriber station, wherein the state of the data connection is monitored in the subscriber station in a monitoring module as part of an application program in the application layer at least based on measurements in the physical layer, and that the measurements in the physical layer are passed on directly to the application layer without passing through one or more intermediate layers or are collected by the application layer from the layer providing the measurements, wherein information about the state of the transmission network is also taken into consideration for the state assessment in the monitoring module. ### Claim 2 (depends on 1) The method of claim 1, wherein parameters of the data connection, are also passed on to the application layer in addition to the measurements in the physical layer. ### Claim 3 (depends on 2) The method of claim 2, wherein the information passed on to the monitoring module about the state of the transmission network is the information about the network load and/or information about the state of the subscriber station in the network. ### Claim 4 (depends on 3) The method of claim 3, wherein the information about the state of the subscriber station in the network specifies whether the subscriber station has come close to a cell boundary. ### Claim 5 (depends on 4) The method of claim 4, wherein the subscriber station transmits the information about the current position of the subscriber station and the planned route to the network management unit. ### Claim 6 (depends on 2) The method of claim 2, wherein the information about the state of the transmission network is predicted by a network management unit into the future, and is sent from the network management unit to the subscriber station. ### Claim 7 (depends on 6) The method of claim 6, wherein the information about the current position of the subscriber station and the planned route of the subscriber station is considered for the prediction of the state of the transmission network. ### Claim 8 A subscriber station for use in a method for monitoring the quality of a data connection, wherein the data about a radio channel subject to interference in a cell of a transmission network are transmitted to at least one mobile subscriber station, wherein the state of the data connection is monitored in the subscriber station in a monitoring module as part of an application program in the application layer at least based on measurements in the physical layer, and that the measurements in the physical layer are passed on directly to the application layer without passing through one or more intermediate layers or are collected by the application layer from the layer providing the measurements, wherein information about the state of the transmission network is also taken into consideration for the state assessment in the monitoring module, the subscriber station further comprising a monitoring module monitoring the state of the data connection at least based on measurements in the physical layer, wherein the monitoring module is part of the application program on the application layer, and collects the information regarding the current state of the connection directly from the layer providing the measurements without passing through one or more intermediate layers or assembles the information from the layer providing the measurements, wherein the monitoring module collects information regarding the state of the transmission network from the layer providing the network state information or assembles the information from the layer delivering the network state information and performs a state assessment for the data connection based on at least the measurements in the physical layer and the information about the state of the transmission network. ### Claim 9 (depends on 8) The subscriber station of claim 8, wherein the subscriber station transmits the information about the current position of the subscriber station and the planned route to a network management unit, and receives the information about the state of the transmission network from the network management unit. ### Claim 10 (depends on 9) The subscriber station of claim 9, wherein the information regarding the current state of the connection relates not only to the measurements in the physical layer but also to parameters of the data connection. ### Claim 11 A network management unit for use in a method for monitoring the quality of a data connection, wherein the data about a radio channel subject to interference in a cell of a transmission network are transmitted to at least one mobile subscriber station, wherein the state of the data connection is monitored in the subscriber station in a monitoring module as part of an application program in the application layer at least based on measurements in the physical layer, and that the measurements in the physical layer are passed on directly to the application layer without passing through one or more intermediate layers or are collected by the application layer from the layer providing the measurements, wherein information about the state of the transmission network is also taken into consideration for the state assessment in the monitoring module, the network management unit further comprising a unit for monitoring the network state, wherein the unit for monitoring the network state sends particular information about the network state to one or more subscriber stations for receiver-end appraisal of the quality state of the network. ### Claim 12 (depends on 11) The network management unit of claim 11, wherein the unit for monitoring the network state predicts the information about the state of the transmission network into the future. ### Claim 13 (depends on 11) The network management unit of claim 11, wherein the unit for monitoring the network state sends the information about the network load and/or information about the state of the subscriber station in the network to one or more subscriber stations. ### Claim 14 (depends on 13) The network management unit of claim 13, wherein the information about the state of the subscriber station in the network specifies whether the subscriber station has come close to a cell boundary. ### Claim 15 (depends on 11) The network management unit claim 11, wherein the unit for monitoring the network state is part of a mobile radio base station eNodeB. ### Claim 16 (depends on 2) The method of claim 2, wherein the parameters of the data connection include the allocated bandwidth and/or the type of modulation used with the set modulation parameters. ### Claim 17 (depends on 10) The subscriber station of claim 10, wherein the parameters of the
