Definitions
- Radio communication systems are used to transmit information, voice or data using electromagnetic waves via a radio interface between a transmitting and a receiving radio station.
- An example of a radio communication system is the well-known GSM mobile radio network, as well as its further development GPRS, the architecture of which is described, for example, in B Walke, mobile radio networks and their protocols, Volume 1, Teubner-Verlag Stuttgart, 1998, pages 139 to 151 and pages 295 to 311 is.
- a channel formed by a narrow-band frequency range and a time slot is provided for the transmission of a subscriber signal.
- a radio communication system for example a GSM mobile radio network with GPRS, comprises a large number of packet data service nodes (serving GPRS support node)
- the radio communication system comprises mobile switching parts which are networked with one another and which provide access to a fixed network.
- the packet data service nodes and the mobile switching centers are also connected to base station controllers (BSC).
- BSC base station controllers
- Each base station controller in turn enables a connection to at least one base station (BTS) and manages the radio technology resources of the connected base stations.
- BTS base station
- Base station and base station control are referred to as the base station system.
- a base station is a transceiver unit which can set up a communication link to subscriber stations via a radio interface.
- a radio channel from the base station to the subscriber station is used as a downward radio channel or downlink radio channel and a radio channel from the subscriber station to the base station is used as Radio channel called upward or uplink radio channel.
- a dedicated channel is assigned to the subscriber station, via which a message transmission can take place.
- Novel data services have been proposed in which a radio station, for example a base station, transmits data without these data being assigned to a special connection. Rather, the data are sent in the form of a radio broadcast and can be received by all subscriber stations located in the radio communication network, in particular within the range of the base station or by a defined group of subscriber stations located in the radio communication system. The receiving subscriber stations can be in the idle state, i.e. Tdle Mode.
- These services also include the service proposed under the term "Multimedia Broadcast Multicast Services" with the abbreviation "MBMS" for the GERAN standard and the UTRAN standard.
- MBMS Multimedia Broadcast Multicast Services
- Potential subscribers to such data services can be registered in the radio communication system. They are then provided with an identifier and can be assigned as a group to specific signaling channels, for example as a paging group to a paging channel. These services are billed through registration.
- the data are only transmitted by a network radio station. That is, it only radio channels in the downward direction are used.
- radio communication systems for example in accordance with or similar to the GERAN standard, one radio channel in the downward direction and one radio channel in the upward direction are permanently assigned to one another. In this case, only the downlink radio channel is used for these data services.
- the invention is based on the problem of specifying a method for operating a radio communication system in which
- Radio channels in the upward direction and radio channels in the downward direction can be used effectively.
- a subscriber station receives data which are transmitted by a network-side radio station via a radio channel in the downlink direction, without a logical connection between the subscriber station and the network side Radio station is set up.
- the network-side radio station is designed, for example, as a base station system with a base station and base station controller.
- the data is, for example, data from an MBMS service. From the subscriber station, one is assigned via a radio channel in the uplink direction, which is assigned to the radio channel in the downlink direction, via which the data is sent
- Sent message This message is from the network side Radio station transmitted via the radio channel in the downward direction.
- the message can also be received by all participants, the data from the network side
- Radio station are sent over the radio channel in the downward direction, received.
- the message can be, for example, a comment on the data received. If the received data represents a video clip, for example, the message can contain feedback on the video clip.
- the subscriber station takes the parameters of the assigned radio channel in the waiting direction of a signaling message from the network-side radio station.
- the subscriber station determines the parameters of the assigned radio channel in the upward direction based on the parameters of the radio channel in the downward direction.
- the transmission of the message over the radio channel in the downward direction is preferably carried out with a lower priority than the transmission of the data over the radio channel in the downward direction. This ensures that the deadline requirement for the transmission of data via the radio channel in the downward direction can be met.
- the message is preferably mirrored in the network-side radio station and transmitted multiplexed with the data via the radio channel in the downward direction.
- the message is received in the network-side radio station and transmitted together with the data by the network-side radio station via the radio channel in the downward direction.
- An advantage of this procedure is that the rest of the radio communication system is not burdened with the message. It is particularly conceivable that no fees are charged for the message that only reaches the network-side radio station.
- This identifier can be entered in the radio link control medium access control protocol, for example.
- the message can be sent from the subscriber station to the network-side radio station without a logical connection being established between the radio station and the network-side radio station, i. H. when the subscriber station is in idle mode or in so-called idle mode.
- the message can be transmitted between the subscriber station and the network-side radio station if a connection for packet data transmission is set up between the subscriber station and the network-side radio station.
- a special type of connection can be provided in the radio communication system, which is reserved for messages of this type that are sent via radio channels in the uplink direction and are assigned to the radio channels in the downlink direction, via which data are sent, without a logical connection between the transmitter network radio station and the data receiving subscriber stations is set up.
- the method allows the subscribers to interact without requiring a dedicated connection between the network radio station and the subscriber stations.
- the process can be carried out without the involvement of the core network.
- By appropriately prioritizing the messages a negative influence on the data transmission in the radio channel in the downward direction is avoided.
- the method is suitable for all data transmissions that take place without a logical connection between a subscriber station and a network radio station. When the message is received and retransmitted, neither data processing nor subscriber identification are required.
- the method is explained in more detail below using an example which is illustrated in the figure.
- the figure shows a message flow in a radio communication system.
- data is sent in an MBMS data service 1 from a packet switching unit SGSN via a base station system BSS, which comprises a base station controller BSC and a base station BTS.
- BSS which comprises a base station controller BSC and a base station BTS.
- a first subscriber station MSI and a second subscriber station MS2 receive the data transmitted by the MBMS service 1 without a logical connection between the first subscriber station MSI or the second subscriber station MS2 and the base station system BSS existed.
- the first subscriber station MSI sends a message, which contains, for example, feedback on the received data, via a radio channel in the upward direction, which is assigned to the radio channel in the downward direction, via which the data of the MBMS service 1 was sent, to the base station system BSS ,
- a rerouting 3 of the message 2 takes place in the base station system BSS.
- an identifier is entered for the message in the radio link control medium access control protocol, which identifies that this message is not transmitted to the packet switching unit SGSN.
- the message 2 is multiplexed with the data of the MBMS service 1, which are transmitted from the packet switching unit SGSN to the base station system BSS, and in a common transmission 4 via the channel in the downward direction to the first subscriber station MSI and second subscriber station MS2 sent.
- the priority of the message 2 is lower than that of the data of the MBMS service 1, so that real-time requests of the MBMS service 1 are retained. Both the subscriber station MSI and the subscriber station MS2 can now receive the data of the MBMS service 1 and the message 2. In this way, the message 2 is made available to all subscriber stations that receive data from the MBMS service 1.
- the reception, the redirection and the transmission of the message 2 can be carried out free of charge.
- This service is then included in the fee charged for MBMS service 1. No identification of message 2 is carried out in the base station system BSS. It is redirected transparently. It will too how the data of the MBMS service 1 is sent undirected in the sense of a radio transmission.
