Definitions
- the invention relates to a method for transmitting information in a communication system with at least two communicating devices according to the preamble of claim 1.
- the invention further relates to a communication system according to the preamble of claim 10.
- the radio communication systems are of great importance due to the mobility of the participants.
- information for example voice, image information, video information, SMS [Short Message Service] or other data
- information is transmitted with the aid of electromagnetic waves via a radio interface between the sending and receiving station (base station or subscriber station).
- the electromagnetic waves are emitted at carrier frequencies that lie in the frequency band provided for the respective system. Frequencies at 900, 1800 and 1900 MHz are used for the introduced GSM mobile radio system (Global System for Mobile Communication).
- GSM Global System for Mobile Communication
- the access of stations to the common radio resources of the transmission medium is regulated in these radio communication systems by multiple access methods (Multiple Access, MA).
- each transmit and receive frequency band is divided into time slots, with one or more cyclically repeated time slots being allocated to the stations.
- the radio resource time is separated station-specifically by TDMA.
- FDMA frequency domain multiple access methods
- the entire frequency range is divided into narrow-band areas, with one or more narrow-band frequency bands assigned to the stations.
- FDMA frequency domain multiple access methods
- the radio resource frequency is separated on a station-specific basis.
- CDMA code area multiple access methods
- the spreading code which consists of many individual so-called chips, encodes the power / information to be transmitted in a station-specific manner, as a result of which the power to be transmitted is randomly spread over a large frequency range due to the code.
- the spreading codes used by different stations within a cell / base station are mutually orthogonal or essentially orthogonal, as a result of which a receiver recognizes the signal power intended for it and suppresses other signals.
- CDMA the radio resource power is separated by spreading codes on a station-specific basis.
- OFDM orthogonal frequency division multiple access methods
- the data are transmitted in broadband, the frequency band being divided into equidistant, orthogonal subcarriers, so that the simultaneous phase shift of the subcarriers spans a two-dimensional data flow in the time-frequency range.
- OFDM separates the radio resource frequency using station-specific orthogonal subcarriers.
- the combined data symbols transmitted on the orthogonal subcarriers during a time unit are referred to as OFDM symbols.
- the multiple access methods can be combined. Many radio communication systems use a combination of the TDMA and FDMA methods, with each narrowband frequency band being divided into time slots.
- the TDD mode is characterized in particular by the fact that a common frequency band for both signal transmission in uplink 2716
- Downlink is used as the FDD mode bertragungscardien for the two Ü each uses a different frequency band.
- information can be transmitted channel-switched (CS circuit switched) or packet switched (PS packet switched).
- CS circuit switched channel-switched
- PS packet switched packet switched
- connection between the at least two communicating devices for information transmission takes place at least via a radio communication interface of a radio communication system with a plurality of base stations networked with one another via a base station network.
- the connection is carried out using channels divided into hierarchical protocol layers. These layers are described, for example, in the ISO / OSI reference model, which was created for the extensive standardization of communication systems.
- a mobile terminal as a communicating device on one side of the radio interface and a base station connected to a core network via the base station network.
- BTS Base Transceiver Station
- Node B in the UMTS system
- AP Access Point
- Modern mobile communication systems such as GPRS (General Packet Radio Service) or UMTS are based on proprietary protocols to ensure high mobility to be able to ask. This leads to disadvantages in particular in hybrid communication systems, which are composed of communication systems that are in themselves functioning properly.
- the proprietary radio communication protocols are not IP-transparent (Internet Protocol). Because of the different types of protocols, an end-to-end connection based on the Internet protocol is therefore not possible.
- a radio connection via the radio interface from a base station to a mobile terminal can be held in a specific radio channel (e.g. frequency), although a better quality of the radio connection could be ensured in another available radio channel (e.g. with a different frequency).
- a specific radio channel e.g. frequency
- another available radio channel e.g. with a different frequency
- the present invention is therefore based on the object of demonstrating a method and a communication system of the type mentioned at the outset by which the communication can be improved.
- the quality of the radio connection should be taken into account as far as possible.
- At least one channel for the radio connection between a communicating device and at least one base station is given channel-specific information to a higher hierarchical channel, which is an Internet protocol-based channel for the overall connection between the at least two communicating devices.
- the channel-specific information includes, in particular, layer-specific information which, for example, according to the ISO / OSI model, is not intended to be passed on and / or processed to higher layers, but is only used for information in the same and / or possibly lower layers.
- the invention therefore means a certain break with the strict system architecture of the protocol layers.
- the information to be passed on to hierarchically higher channels or layers relates primarily to information from layer 1 and / or layer 2 according to the ISO / OSI model.
- the hierarchically higher channel or channels to which the information from hierarchically subordinate channels are transmitted according to the invention relate in particular to layer 4 or higher layers according to the ISO / OSI model.
- the hierarchically higher layer can act proactively, so that overall there is a quick and effective possibility for the communication system to maintain or establish the best connection, if for example, there are signs of a loss in quality with regard to the radio connection.
- bit transmission channel-specific information about the physical radio connection between a communicating device and at least one base station and on a hierarchically higher, Internet protocol-based channel are given. This means that layer 1 information is transmitted to higher layers.
- channel-specific information is given to the hierarchically higher, Internet protocol-based channel from a data link layer channel for securing the radio connection between a communicating device and at least one base station.
- layer 2 information is transmitted to higher layers.
- the data link layer can, for example, fall into the sub-layers Medium Access Control (MAC), Radio Link Control (RLC), Packet Data Convergence Protocol (PDCP) and Broadcast / Multicast Control (BMC).
- MAC Medium Access Control
- RLC Radio Link Control
- PDCP Packet Data Convergence Protocol
- BMC Broadcast / Multicast Control
- the information given to hierarchically higher channels can in principle include and contain all suitable information.
- parameter information relating to the radio connection between the communicating device and the base station can be transmitted to higher layers.
- information about the quality of service (QoS Quality of Service) of the radio connection can be affected.
- the parameter information can in particular contain measurement results - for example from measurements of the radio channel quality.
- the information can also relate to calculations from information relating to the radio connection between the communicating device and the base station. In particular, calculations that are carried out on layer 1 and / or for layer 1 are addressed here.
- the information can advantageously relate to control information relating to the radio connection between the communicating device and the base station.
- information from the RLC layer can be transmitted.
- an Internet protocol-based channel is used for the connection between the at least two communicating devices in accordance with the SCTP protocol.
- SCTP Stream Control Transmission Protocol
- This SCTP Stream Control Transmission Protocol
- Stream Control Transmission Protocol relates to a recently developed technology for the transport of signaling messages via IP-based wired networks.
- a use in connection with radio communication networks was not previously planned. Surprisingly, it has now been shown that this protocol can be used advantageously for radio communication networks.
- SCTP In contrast to other Internet protocol communications such as TCP / IP, SCTP enables, in addition to the pair of IP addresses active in the physical connection, one or more additional IP address pairs, via which other physical connections could be activated immediately. In the event of a malfunction or an interruption in communication, a significantly faster change to an alternative physical connection can therefore be carried out.
- IP addresses can be about what the Be ⁇ may drop a connection made to be allocated.
- the various radio communication systems can be used additively or alternatively.
- the various access networks can relate, for example, to a UMTS system, a GSM system and / or a WLAN system (Wireless LAN - Local Area Network).
- the WLAN system can be specified according to the HIPERLAN / 2 standard, according to the IEEE 802.1lla standard or according to the HiSWAN-A standard.
- a change with respect to at least one multiple access medium and / or a handover is initiated on the basis of the higher hierarchical information.
- the frequency, the time slot and / or the code used can be changed based on the information transmitted.
- all known types of handover can be initiated, for example the variants known as so-called hard (break-before-make) or soft (make-before-break) handovers.
- a laptop can switch the connection from one base station to another if, for example, a person stands between the laptop and the initially active base station and the line (sight) connection has been interrupted or impaired.
- a similar change can be made for handovers between different base stations of the same technical radio communication system. For example, if a radio connection deteriorates, the mobile station can set an IP
- a handover between base stations belonging to different radio communication systems is also possible.
- a base station can belong to the UMTS network and another base station can be part of a WLAN network.
- a change can be initiated here, for example, because of the quality of the connection, because of the network-specific nature of the different network connections, such as different costs, and / or because of network-specific availability of special services.
- the invention leads to an increase in performance with a simultaneous reduction in the signaling effort and thus to a reduction in interference.
- knowledge that has been obtained in connection with the publicly funded projects BRAIN and MIND can be used. This applies in particular to the so-called IP 2 W interface (IP to Wireless Interface).
