Definitions
- the invention relates to a method for transmitting information in a radio communication system according to the preamble of claim 1.
- the invention further relates to a device for radio access control between at least one base station and subscriber stations via an air interface in a radio communication system according to the preamble of claim 6.
- information for example voice, image information, video information, SMS [Short Message Service] or other data
- information is generated with the aid of electromagnetic waves via a radio interface between the sending and receiving station (base station or
- 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). These systems essentially transmit voice, fax and short messages (SMS), as well as digital data.
- 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 means of multiple access methods (Multiple Access, MA).
- the connection between a base station and a subscriber station takes place via an air interface.
- the base station can operate several radio cells.
- At least one base station and a device for radio access control are components of a base station subsystem (RNS, radio network subsystem).
- RNC radio access control
- a radio communication system generally comprises several base station subsystems that are connected to a core network (CN, Core Network).
- CN Core Network
- Various methods are known for addressing subscriber stations in radio communication systems.
- the broadcast call in which all subscriber stations within the radio range of the sending base station are addressed, is most frequently represented.
- group-station call multicast
- a multicast in which all radio stations within the range of a base station are addressed, corresponds to a broadcast.
- MBMS Multimedia Broadcast / Multicast Service
- Different MBMS services multimedia broadcast / multicast service
- the subscriber stations of these subscribers who want to use the service are notified. This notification of the subscriber stations is necessary so that the receivers can be configured. Depending on the mode in which the subscriber stations are (e.g. "connected mode”, connection mode or "idle mode", idle period), the notification is given. Group-specific mechanisms are usually used for notification, in which several subscriber stations are addressed simultaneously.
- the invention has for its object to show a method of the type mentioned, which contributes to the efficient design of the notification of subscriber stations of a group. Furthermore, a device for radio access control of the type mentioned at the outset is to be shown which enables such effective notification of subscriber stations of a group. This object is achieved for the method by a method with the features of claim 1 and for the device for radio access control by a device with the features of claim 6.
- the radio communication system comprises subscriber stations and at least one device for radio access control between at least one base station and subscriber stations. Before user information is made available to a group of subscriber stations by radio, these subscriber stations are notified. According to the type of notification depends on at least one subscriber station
- a group consists of at least one subscriber station, but usually consists of a plurality or a plurality of subscriber stations.
- the maximum number of subscriber stations within the group corresponds to the number of subscriber stations in the radio communication system.
- the radio communication system can thus subscriber stations of the group and other subscriber stations, which e.g. can belong to other groups, or include only those subscriber stations that belong to the group.
- a property of the subscriber station can be a property that is present, for example, ex works, which cannot be changed without mechanical intervention in the hardware of the device, such as the number or structure of transmitting and receiving units. Furthermore, it can be a property that can be programmed, for example, by the operator or by the subscriber. Finally, a combination of properties can also be relevant for the type of notification.
- the dependency of the type of notification on at least one property of the subscriber station affects at least one subscriber station in the group. It can affect any number of group members up to the total number of subscriber stations in the group. It is also possible that the subscriber stations, which are subject to such a dependency with regard to the notification, by a condition or a common parameter, such as a regional restriction or a contract with the operator of the
- Radio communication system or an operating mode are determined.
- the type of notification is a group-specific or a subscriber-specific notification. While a group-specific notification is intended for reception and processing within a group of subscriber stations, the addressee of a subscriber-specific notification consists of an individual subscriber.
- the subscriber stations can use types of notification e.g. Use a service identification number to determine the service for which this notification is valid. Different types of notifications may be sent to different subscriber stations.
- the at least one property of the subscriber station is an ongoing or temporary ability to receive and possibly to process a group-specific notification. This capability thus affects the structure of the entire receiving device of the subscriber station.
- a temporary ability to receive is a ability to receive that is determined by circumstances such as the current operating mode can be disrupted or destroyed.
- the at least one device for radio access control makes a decision about the type of notification.
- the at least one device for radio access control preferably has identification information and local information of the at least one subscriber station about the type of notifying it which the at least one device for radio access control decides.
- Local information refers e.g. to the radio cell in which the subscriber station is currently located.
- the identification information e.g. in UMTS the U-RNTI (Utra Radio Network Temporary Identifier) of a subscriber station is known as unique identification information of the device for radio access control when the subscriber station is in connection mode.
- the device for radio access control has means for deciding on the type of notification of at least one subscriber station of the group based on at least one property of this subscriber station.
- Suitable means and devices for carrying out the method steps can be provided in the device for radio access control.
- FIG. 1 a section of a radio communication system
- FIG 2 a flow chart of a method according to the invention.
- the exemplary embodiment relates to a radio communication system according to the UMTS standard.
- Figure 1 shows a section of such a radio communication system of the third generation.
- This includes a device RNC for radio access control, which is connected to a base station ⁇ ODE B and a core network C ⁇ .
- the function of the RNC device for radio access control is to control and monitor the base stations connected to it with their respective radio cells.
- the base station ⁇ ODE B operates such a radio cell in which the subscriber stations UE1,
- UE2, UE3, UE4 and UE5 are located.
- the subscribers to the respective subscriber stations UE1, UE2, UE3, UE4 and UE5 were subscribed to a multicast service.
- the subscriber stations UE1, U2, UE3, UE4 and UE5 thus form a group.
- Further subscriber stations (not shown in FIG. 1) outside the group defined by the subscription of the subscribers can be in the radio cell of the base station, but these are not significant for the explanation of the method according to the invention.
- the base station ⁇ ODE uses information such as Exchange information or videos sent, which the subscriber stations UE1, UE2, UE3, UE4 and UE5 of the group can receive and decrypt. Subscriber stations other than the subscriber stations UE1, UE2, UE3, UE4 and UE5 of the group cannot decrypt this multicast information. In order to be able to configure the subscriber stations UE1, UE2, UE3, UE4 and UE5 of the multicast group, it is necessary to notify them before the user information is transmitted.
- a subscriber station in the radio communication system After a subscriber station in the radio communication system is switched on, it is in an idle mode.
- This mode is characterized in that this subscriber station is known in the core network CN, but not in the radio access network (RAN) of the radio communication system by means of identification information.
- An RNC device for radio access control it remains hidden which subscriber stations are in idle mode in the radio cells of the base stations connected to them.
- a subscriber station in idle mode does not exchange any information with the radio network until a connection request is made by the subscriber station. After such a connection request, the subscriber station switches to connection mode.
- a connection request can be initiated, for example, by the subscriber station's request for a service or also by a paging request from the radio network.
- the subscriber stations of the radio communication system which are in a connection mode, are known to the respective radio access control device on the basis of identification information and can thus be localized.
- the corresponding identification information was transmitted to the radio access control device by the subscriber station.
- the core network can also transmit information about the respective subscriber station to the device for radio access control. While the connection mode is active, the respective subscriber stations monitor different radio channels than the subscriber stations which are currently in idle mode. A subscriber station can also be in a connection mode if no physical channel is currently assigned to it.
- the subscriber stations UE1, UE2 and U ⁇ 3 are in the idle mode IM, whereas the subscriber stations UE4 and UE5 are in the connection mode CM.
- the RNC for radio access control thus knows the subscriber stations UE4 and UE5, while it has no knowledge of the location of the subscriber stations UE1, UE2 and UE3 within the coverage area of the base station NODE B.
- the notification of the subscriber stations UE1, UE2 and UE3 in the idle mode IM via an expected multicast Information is provided via a paging channel, which these subscriber stations UE1, UE2 and UE3 observe in the idle mode IM.
- This notification is group-specific information which is addressed exclusively to the subscriber stations UE1, UE2, UE3, UE4 and UE5 of the group. Other subscriber stations do not have to watch the paging channel in question.
- This group-specific notification means that several subscriber stations are addressed simultaneously.
- connection mode CM Whether the subscriber stations UE4 and UE5 in connection mode CM can receive and process the information of the paging channel depends on the capacities of these subscriber stations UE4 and UE5 in connection mode CM. As a rule, some subscriber facilities are so-called simple
- Subscriber facilities unable to simultaneously use dedicated channels for e.g. Receive voice connections and channels for group-specific notifications. These subscriber stations require a subscriber-specific notification addressed to them about the expected one
- the separate notification of subscriber stations about expected multicast information increases the utilization of the respective radio access control device considerably, especially with a large number of group subscribers within a radio cell. Due to this undesirable effect, a separate notification is only sent to a subscriber station in connection mode if the subscriber station is not able to evaluate the corresponding paging channel. The "better equipped" subscriber stations, which can monitor the paging channel in connection mode, are not sent such a separate subscriber-specific notification.
- the procedure according to the invention can achieve a more effective use of the scarce radio resources. Through the: ' . By sending unnecessary separate notifications and thus by reducing the signaling effort, the interference can be reduced, which results in an increase in the transmission quality within the radio communication system.
- the radio access control device has information about the capacity of the subscriber stations * in connection mode for receiving the paging channel.
- the device for radio access control may have received this information from the subscriber station when changing to the connection mode or also from the core network. On the basis of this information, the device for radio access control can decide how the subscriber stations are to be notified of the multicast information in connection mode.
- Figure 2 shows the sequence of this method.
- the RNC device for radio access control decides which notification each subscriber station should receive in connection mode within the radio cells of the base stations assigned to it.
- the left branch of FIG. 2 describes the procedure in relation to subscriber stations in idle mode and to those subscriber stations in connection mode which can observe the paging channel in this mode.
- the right branch of FIG. 2 on the other hand, relates to those subscriber stations in connection mode which cannot observe the paging channel in this mode.
- a subscriber station If a subscriber station is able to evaluate the paging channel in the connection mode, this takes - like the subscriber stations in the idle mode - the signal PAGING des Paging channel the relevant information about the multicast service.
- the subscriber stations which have received the paging message reply with a signal ANSWER to the respective base station NODE B. This answer can be found by the radio access control device as to whether there is a need to transmit the multicast information in the radio cells concerned. It is also possible that the subscriber stations do not answer the notification through the paging channel.
- a subscriber-specific notification MESSAGE is sent to each subscriber station in connection mode which cannot receive the paging channel.
- This MESSAGE notification contains the same information as the PAGING signal.
- the subscriber station can send a response ANSWER to the relevant base station NODE B.
- the MULTICAST INFO of the multicast service is sent from the base stations NODE B to the subscriber stations UE of the group.
- connection mode and the idle mode can also be included in the decision about the type of notification.
