The link is realized using channels arranged in hierarchical protocol layers. Channel-specific information is given to a hierarchical higher channel at least from one channel for the radio link between a communicating device and at least one base station. This hierarchically higher channel is an Internet protocol-based channel for the overall link between the at least two communicating devices. ## Claims ### Claim 1 A method for transmitting information in a communication system with at least two communicating devices, comprising: linking the at least two communicating devices for transmission of the information at least via a radio communication interface of a radio communication system having base stations interlinked via a base station network, said linking using channels arranged in hierarchical protocol layers; supplying channel-specific information, at least from one channel for a radio link between one of the communicating devices and at least one base station, to a hierarchically higher Internet protocol based channel for an overall link between the at least two communicating devices; and initiating at least one of a changeover in respect of at least one multiple access medium and a handover based on the channel-specific information supplied from the channel for the radio link to the hierarchically higher Internet protocol based channel for the overall link. ### Claim 2 (depends on 1) A method according to claim 1, wherein said supplying sends the channel-specific information to the hierarchically higher Internet protocol based channel via a bit transmission channel to provide specific information about a physical radio link between the one of the communicating devices and the at least one base station. ### Claim 3 (depends on 2) A method according to claim 2, wherein said supplying supplies the channel-specific information to the hierarchically higher Internet protocol based channel via a data link layer channel to ensure the radio link between the at least one of the communicating devices and the at least one base station. ### Claim 4 (depends on 2) A method according to claim 2, wherein the channel-specific information relates to parameter information about the radio link between the at least one of the communicating devices and the at least one base station. ### Claim 5 (depends on 2) A method according to claim 2, wherein the channel-specific information relates to calculations on data relating to the radio link between the at least one of the communicating devices and the at least one base station. ### Claim 6 (depends on 3) A method according to claim 3, wherein the channel-specific information is control information related to the radio link between the at least one of the communicating devices and the at least one base station. ### Claim 7 (depends on 1) A method according to claim 1, wherein said linking further uses an Internet protocol based channel between the at least two communicating devices in accordance with a stream control transmission protocol. ### Claim 8 (depends on 7) A method according to claim 7, wherein said linking uses different access networks to provide the radio communication interface. ### Claim 9 A communication system, comprising: at least two communicating devices; base stations; a base station network interlinking said base stations; means for transmitting channel-specific information at least from one channel for a radio link between one of said communicating devices and at least one of said base stations to a hierarchically higher Internet protocol based channel for an overall link between said communicating devices; and means for initiating at least one of a changeover in respect of at least one multiple access medium and a handover based on the information transmitted by said transmitting means from the channel for the radio link to the hierarchically higher Internet protocol based channel for the overall link. ### Claim 10 (depends on 9) A communication system according to claim 9, wherein said transmitting means sends the channel-specific information to the hierarchically higher Internet protocol based channel via a bit transmission channel to provide specific information about a physical radio link between the one of said communicating devices and the at least one of said base stations. ### Claim 11 (depends on 10) A communication system according to claim 10, wherein said transmitting means supplies the channel-specific information to the hierarchically higher Internet protocol based channel via a data link layer channel to ensure the radio link between the one of said communicating devices and the at least one of said base stations. ### Claim 12 (depends on 10) A communication system according to claim 10, wherein the channel-specific information relates to parameter information about the radio link between the one of said communicating devices and the at least one of said base stations. ### Claim 13 (depends on 11) A communication system according to claim 11, wherein the channel-specific information relates to calculations on data relating to the radio link between the one of said communicating devices and the at least one of said base stations. ### Claim 14 (depends on 11) A communication system according to claim 11, wherein the channel-specific information is control information related to the radio link between the one of said communicating devices and the at least one of said base stations. ### Claim 15 (depends on 10) A communication system according to claim 10, wherein said linking further uses an Internet protocol based channel between said at least two communicating devices in accordance with a stream control transmission protocol. ### Claim 16 (depends on 15) A communication system according to claim 15, further comprising different access networks providing the radio communication interface.
