Communication systems used for transmission of information, speech or data with the aid of electromagnetic waves via a radio interface between transmitting and receiving stations. An example of a radio system is a well-known network mobile radio standard GSM (global system for mobile communications)and the next version of GPRS (General services packet), the architecture of which is described, for example, in the publication B.Walke, Mobilfunknetze und ihre Protokolle, Band 1, Teubner-Verlag, Stuttgart, 1998, S.139-151, 295-311. At the same time to transmit the user signal, respectively, provided the channel formed by narrow-band frequency range and a temporary segment.
For packet data communication system includes, for example, the mobile radio network GSM with GPRS, the set of nodes of the packet data services (service nodes GPRS support nodes SGSN), which are interconnected by a network and which provide access to a fixed network data. Data circuit-switched radio system contains switches for mobile communications, which are connected to the network and which provide access to a fixed network. The nodes of the packet data services, and switches the mobile communication associated with base station controllers (BSC). Each base station controller who provides the very useful connection at least one base station (BTS) and manages the radio resources of the connected base stations. Such a base station is a transceiver unit, which is using the phone can establish a connection with the mobile stations to transmit messages.
There are two different operation mode of the mobile station in the dormant state, for which this technology uses the concept of "idle" (inactive) mode, there is no logical connection between the mobile station and the base station. In a special condition, which applies the term "specialized mode (mode a dedicated connection), there is a logical connection between the mobile station and the base station in which the mobile station corresponds to the selected channel, which can be sending messages.
They proposed new data services, in which the radio station, for example base station that transmits data without establishing a special connection to transfer this data. On the contrary, these data are transmitted like radio and can be taken all in the radio communication network of the mobile stations or a specific group of mobile stations in the communication system. The receiving mobile station can the ri to be in the inactive mode. To denote these services applies the term "multimedia services broadcast/multicast" (MBMS). These data services are provided as in radio systems, the relevant standard GERAN, or the like, and in the UTRAN standard. In this regard, we can refer to the Technical report 3GPP TR 23.846 6.1.0 (2002-12) Project partnership in creating systems of the third generation; Technical specifications group services and system aspects; Multimedia service and a broadcast/multicast (MBMS); Architecture and functional description (Release 6).
Potential users of such services, data transmission can register in the communication system. Then they are given a code, and they, as a group of specific signaling channels, such as the group of search and call, may be provided to one channel search call.
For future radio communication systems is required to ensure that such services data should only be transferred from the separate radio communication systems. In particular, when the coverage area of a different radio network radio stations overlap, it is considered sufficient when the individual network stations undertake the transfer of data transmission services.
The basis of the invention lies in the task of creating a method of implementation in the Luga data transmission in the communication system, when data transmission services data transmission, which can be used by mobile stations in the inactive state, only via a separate radio communication systems, and yet it is guaranteed that the mobile stations are in idle state, will be able to receive the data service.
This task in accordance with the invention is solved by a method according to paragraph 1 of the claims. Further embodiments of the invention are reflected in the dependent claims.
In accordance with the invention method for implementing data services in a communication system, which may be a mobile station in an idle state, the first network radio station transmits on channel signaling, which may be a mobile station in an idle state, information about the data service. Information includes, at least, the code data transmission services and instruction to identify a second network station, which is passed through the data in this data transmission services. The signaling path through which information is transmitted may, for example, be a channel broadcasting, in particular the control channel of the broadcast (SSN) or channel mobile call, which is referred to as the channel search is the first call (RSCN), and through which the called mobile station in an idle state, for which the radio system-generated call. In this way, the mobile station on the basis of existing in the communication system of selection rules listens to the first network station receives information about which network stations can be received service data.
The preferred way, information about the data service provides the indication to identify the second network radio station, through which data is transmitted data services. The indication for identification of the radio channel may, for example, include the transmission frequency, timing information, a scheme of changing the frequency, etc. If this information is provided to the mobile station, it is able to synchronize the receiver with the second network radio station, tune in to the applied frequency and receive data data services.
The preferred way, an indication to identify the channel contains a reference to another channel signaling, transmitting the message from the radio coordinates of the radio channel and the second radio station. This way it saves radio resources of the first named channel signaling, which, for example, must simultaneously be used the AK channel mobile call. The bigger message is transmitted on another channel signaling, which is only indicated in the service information data.
Depending on the size of the message with a radio coordinates of the radio channel is expedient in another signaling path to send the message to provide the radio resource. The radio resource may, for example, represent one or more specifically for this purpose allocated blocks radio communication.
If potential users of data services registered in the communication system, it is preferable to provide information about the service transfer code for registered users. This can be done, for example, so that potential users of data services together in a group of mobile call or group search call, which is achievable through a single channel mobile call or channel search call.
According to a variant implementation of the invention, the first radio network and the second network radio station will operate according to different radio access methods. In this case, information about the data service contains a list of network stations, which are operated using the same radio access method, and the second network Redist ncia, and through which data are transferred to data services. In this case, the first radio station there is no detail given radio coordinates a network of radio stations with other methods of communication. Therefore, information about the data service can be provided only information about which network station support other methods of wireless access to the service data. A mobile station that would like to take data data services, should make a choice of the possible network of radio stations through which data is transmitted data services. The first network radio station may, for example, operate using radio access method corresponding to the GERAN standard, while the second network radio station can be operated using a radio access method corresponding to the standard UTRAN, or Vice versa.
A mobile station that receives information about the data service, thus, can send their admission to the second network radio station and receive data services data transmitted to the second network radio station. The more information about the second network station is contained in the service information data, the faster the mobile station may start receiving data plugoperate data.
The preferred way to transfer information about the data service and the beginning of data transmission services data transmission are offset in time by a specified delay time. Thus, mobile stations who have received service information, data, during this delay time is given time to adjust their admission to the second network radio station.
The method allows the communication system to save bandwidth due to the fact that the service data that can be received by mobile stations in the inactive state, must not be passed on all the network stations, and simultaneously ensures that the mobile station being in an idle state, which it is desirable to accept the service data, receive information about the network radios that transmit data data services. The need for bandwidth for information about the data service is much lower than the actual data.
The method is compatible with the algorithms for the selection of cells through which existing systems of radio communication mobile station located in an inactive state, selects the channel signaling network of radio stations.
Because the second network radio station and the first network radio station located in the ne region location, to indicate which used the terms "location" and "area routing", it is possible that a mobile station simultaneously with the reception data transmission data through the second network radio station may establish other connections to the circuit-switched or packet-switched from the second mobile station.
Choosing a network of radio stations through which the data should be taken will be made solely in the radio access network. The base network is not affected.
The method is compatible with existing mechanisms of reception data services type of MBMS. Therefore, it can be implemented without major changes to the existing system.
Hereinafter the invention is explained in more detail in the exemplary embodiment illustrated in the drawing.
The drawing shows the procedure of the transfer of messages between the first network radio station and mobile station.
The mobile station MS is registered in the mobile communication system as a potential service user data ID TMGI, which may be a mobile station MS in the idle state, then there is no logical connection between a mobile station FS1 and network radio. The first network radio station, for example base station of a mobile communication system GERAN or node In the system UTRAN transmits on channel PCH POI is the same call, which can be taken by the mobile stations that are registered as potential users of data services code TMGI, information 1 about the data service that contains the service code data TMGI and the indication of the second channel signaling(PAGCH). On the second signaling path is the allocation of 2 radio resource, for example a block to the radio for straight direction. Through the second channel signaling (PAGCH)) of the first network radio station FS1 passes in the selected block to the radio note 3 to identify the second network radio station FS2, through which data are transmitted data services code TMGI. Note 3 contains, for example, the code of the cell associated with the second network radio station FS2 used for data transmission frequency, timing information, information about the applied method, frequency-hopping, etc.
As the mobile station MS is registered as a potential user of the data transmission service ID TMGI, it can take the information 1 and note 3. Using these instructions, in particular the applied frequency and data synchronization, the mobile station MS synchronizes its receiver with the specified channel of the second network radio station FS2, and sets it on the used frequency. It then takes the data is e 4, which are transmitted to the second network radio station FS2 as data services. Data transfer 4 data services runs after a specified time delay after sending information 1 from the first network radio station. The delay time is, for example, 1 second.
If the note 3 for identification of the radio channel contains only a small amount of data, specifying 2 for resources may not take place, and the note 3 can be transmitted together with the passed block broadcasts.
