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, 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 described.
  • 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 SGSN) which are networked with one another and which provide access to a fixed data network.
  • the radio communication system comprises mobile switching centers 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 resources of the connected base stations.
  • BTS base station
  • Such a base station is a transceiver unit which can set up a message connection to mobile stations via a radio interface.
  • 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 mobile stations located in the radio communication network or by a defined group of mobile stations located in the radio communication system. The receiving mobile stations can be in the idle state, i.e. ldle fashion.
  • the term "multimedia broadcast multicast services” with the abbreviation "MBMS” is used for these services.
  • These data services are provided both in radio communication systems in accordance with or similar to the GERAN standard and the UTRAN standard. In this regard, please refer to the Technical Report 3GPP TR 23.846 6.1.0 (2002-12) 3rd Generation Partnership Project, "Technical Specification Group Services and System Aspects, - Multimedia Broadcast / Multicast Service
  • 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.
  • the invention is based on the problem of specifying a method for operating a data service in a radio communication system, in which the transmission of data from the data service, which can be used by mobile station stations in the idle state, only takes place via individual radio stations of the radio communication system and is nevertheless guaranteed, that mobile stations that are idle can receive the data service.
  • a first network radio station sends information about the data service on a signaling channel that can be received by mobile stations in the idle state.
  • the information contains at least one identifier of the data service and an indication for identifying a second network radio station via which data of the data service are transmitted.
  • the signaling channel, via which the information is transmitted can be, for example, a radio channel, in particular a broadcast control channel BCCH, or a mobile call channel, for which the name paging channel PCCH is common, and via the mobile stations in the idle state, for those in the radio communication system There is a call, be called. In this way, a mobile station that listens to the first network-based radio station on the basis of the selection rules present in the radio communication system receives the information of which rather network-side radio station the data service can be received.
  • the information about the data service preferably contains information for identifying a radio channel of the second network radio station via which data from the data service are sent.
  • the information for identifying the radio channel can include, for example, the transmission frequency, synchronization information, frequency change schemes and the like. If the mobile station has this information, it can synchronize its receiver to the radio channel of the second network radio station and tune it to the frequency used and receive the data from the data service.
  • the information for identifying the radio channel preferably contains a reference to another signaling channel on which a message with the radio-technical coordinates of the radio channel and the second radio station is sent.
  • the radio resources of the first-mentioned signaling channel which, for example, must be used simultaneously as a mobile call channel, are saved.
  • the more extensive message is sent via the other signaling channel, to which reference is merely made in the information about the data service.
  • the radio resource can, for example, consist of one or more radio blocks specially assigned for this purpose.
  • potential subscribers to the data service are registered in the radio communication system, it is advantageous to provide the information about the data service with an identifier for registered subscribers. This can be done, for example, by the potential participants in the data service can be combined to form a mobile call group or paging group that can be reached via the same mobile call channel or paging channel.
  • the first network radio station and the second network radio station are operated with different radio access technologies.
  • the information about the data service contains a list of network-side radio stations which are operated with the same radio access technology as the second network-side radio station and via which data of the data service are transmitted.
  • the first network radio station generally does not have any more specified radio coordinates of the network radio stations of the other radio access technology. Therefore, only the information about which network-side radio stations of the other radio access technology support the data service can be provided in the information about the data service.
  • a mobile station that wants to receive data from the data service must then make a selection from the possible network radio stations via which the data from the data service are transmitted.
  • the first network radio station can for example be operated with radio access technology according to the GERAN standard and the second network radio station with radio access technology according to the UTRAN standard or vice versa.
  • a mobile station which receives the information about the data service is thus able to direct its reception to the second network radio station and to receive the data of the data service transmitted by the second network radio station.
  • the more information about the second network radio station that is contained in the information about the data service the faster the mobile station can start receiving the data of the data service.
  • the information about the data service is preferably sent and the start of sending data of the data service takes place at a predetermined time delay. This allows mobile stations that have received the information about the data service during the delay time to direct their reception to the second network radio station.
  • the method makes it possible to save bandwidth in the radio communication system by not having to send out the data service that can be received by mobile stations in the idle state from all network-based radio stations, while at the same time ensuring that mobile stations in the idle state that want to receive the data service , Receive information about the network radio stations that send data from the data service.
  • the bandwidth requirement for information about the data service is much less than that for sending the data service itself.
  • the method is compatible with algorithms for cell selection with which a mobile station in the idle state selects signaling channels from network-based radio stations in existing radio communication systems.
  • the second network radio station and the first network radio station have the same location area, for which the terms “location area” and "routing area” are often used in the professional world, it is possible for the mobile station to receive data at the same time the data service can use the second network radio station to set up line or packet-switched connections to the second network radio station.
  • the selection of the network-side radio station via which the data is received is made exclusively in the radio access network.
  • the core network is not affected.
  • the method is compatible with existing mechanisms for receiving the MBMS data service. It can therefore be implemented without major changes to the existing system.
  • the figure shows a message flow between a first network radio station and a mobile station.
  • a mobile station MS is registered in the radio communication system as a potential subscriber to a data service with an identifier TMGI, which can be received by the mobile station MS in the idle state, that is to say without a logical connection between the mobile station MS and a network-side radio station.
  • a first network-side radio station FS1 for example a base station of a GERAN mobile radio system or a NodeB of a UTRAN system, transmits PCH on a paging channel that can be received by mobile stations that are registered as potential users of the data service with the identifier TMGI , Information 1 about the data service, which contains the identifier of the data service TMGI and a reference to a second signaling channel (PAGCH).
  • PAGCH second signaling channel
  • An allocation 2 of a radio resource, for example a radio block, for the downward direction takes place on the second signaling.
  • the first network-side radio station FS1 in the assigned radio block sends an indication 3 for identifying a radio channel of a second network-side radio station FS2 via which data from the data service TMGI are sent.
  • the specification 3 contains, for example, an identifier of the cell assigned to the second network radio station FS2, the frequency used for the data transmission, synchronization information, information on a frequency hopping method used and the like. Since the mobile station MS is registered as a potential subscriber to the data service TMGI, it can receive information 1 and information 3.
  • the mobile station MS synchronizes its receiver to the specified channel of the second network radio station FS2 and tunes it to the frequency used. Subsequently, it receives data 4, which are transmitted by the second network radio station FS2 for the data service.
  • the transmission of the data 4 of the data service starts a predetermined delay time after the information 1 has been transmitted by the first network radio station. For example, the delay time is 1 second.
  • the specification 3 for identifying the radio channel comprises only a little data
  • the assignment 2 of the resource can be omitted and the specification 3 can also be transmitted in a radio block which is transmitted anyway.
