Definitions
- group call connections between more than two subscribers are known in which traffic channels (traffic channels) exist between at least one speaker and at least one listener.
- traffic channels traffic channels
- group call connections are the "Voice Group Call Service (VGCS) ⁇ according to 3GPP-TS-42.068 (according to which specification speaking, listening, speaking and listening participants as well as dispatchers (who can speak without speech authorization token) are provided) corresponding to a special conference call and the "Voice Broadcast Service (VBS)" according to 3GPP-TS42.069, (according to which speech data of a speaker is transmitted to several listeners in a given area (Voice Broadcast Call Area)) according to a broadcast over one or more cells and / or to specified participants receiving the DDPS.
- VCS Voice Group Call Service
- VBS Voice Broadcast Service
- the object of the present invention is to enable the most extensive possible monitoring of subscribers in a telecommunications network even when using group call connections.
- the object is achieved in each case by the subject matter of the independent claims.
- it is determined for the subscriber initiating the establishment of a group call connection (a connection between more than two subscribers) and for further subscribers of the group call connection whether eavesdropping is provided and (if this is for at least one of the If the group call connection is provided) and the voice data transmitted via the group call connection is made available to a listening device, interception by subscribers of a telecommunications network is more extensive than in the prior art, since the state of the art does provide good monitoring of origination connections (such as from the subscriber requesting the establishment of the group call connection), but not efficiently granted for terminating connections (subscribers who join the group call as listeners).
- Group Call ID Listening device
- Whether at least one subscriber of a group call connection and thus the group call connection as a whole (all voice data transmitted via it) is to be listened to can be done in particular by querying a home register or visitor register of a mobile radio network which contains data on this subscriber.
- group call connections are listened to, in which at least one subscriber to be monitored actively participates in the group connection, that is to say (in particular upon request) has requested the receipt of voice data and / or the transmission of voice data (listener / talker / dispatcher) or automatically for this group call connection has such a status based on specifications.
- groups of subscribers can be defined, whose subscribers participate in a group call connection (ie receive and / or send voice data sent via traffic channels) by answering a registration request for the group call connection positively or by automatically for each Incoming group call connection of this group are provided.
- Checks of participants in a group can be carried out to determine whether they are to be listened to or not during the establishment (i.e. request whether they want to participate in the group call) and / or cyclically. It is also expedient to check participants in the group who join a group call connection later (after a call has been set up). As soon as a subscriber is in the broadcasting area of this / his group or he is classified as listening, all voice data transmitted via the group call connection can be listened to, while it can otherwise be omitted.
- Broadcast service can be transmitted or can be transmitted according to a specification, so that (in particular with a voice broadcast call) a group is only listened to if a subscriber is in the intended service area of the voice broadcast call, which means that the subscriber is asked whether they want to join the group call connection or not.
- a very efficient identification of participants actively participating in a group call is possible in particular by sending a signaling message (in particular an uplink Access Reguest message) to one or all participants of a group for whom a group call is possible ( in particular in an uplink request message on a voice group call down link), whereupon the participants in the group call identify themselves insofar as they are in the transmission area (and possibly insofar as they are interested in and / or activated in the group call) (for example by an IMSI / MSISDN in an answer).
- a signaling message in particular an uplink Access Reguest message
- the participants in the group call identify themselves insofar as they are in the transmission area (and possibly insofar as they are interested in and / or activated in the group call) (for example by an IMSI / MSISDN in an answer).
- the new speaker can be asked with a signaling message to indicate his identity (in a signaling message) before he becomes the speaker, which is checked can be whether this speaker is to be heard.
- Voice data to be eavesdropped is expediently copied in a switching facility, etc. and sent as CC (Content of Communication) to a (usually state) listening center.

- Fig. 1 shows schematically a known group call
- FIG. 2 schematically shows a known VGCS group call according to 3GPPTS42.068
- FIG. 3 shows schematically a known VBS group call according to 3GPPTs42.069
- Fig. 4 shows a group call register GCR
- FIG. 6 shows a monitoring according to the invention by means of a group call ID monitoring in a switching device
- FIG. 7 shows a change of speaker when monitoring a group call.
- FIG. 1 shows an example of a group call (Voice Group Call Service / Voice Broadcast Service) in a mobile radio network.
- the general structure of a mobile radio network is known to the person skilled in the art, for example for a GSM network or 3GGP network from www.etsi.org.
- a switching device indicated as a circle
- dispatchers E, F and the switching device in each case at least one traffic channel.
- subscriber A mobile station A
- speaks while mobile stations B, C, D and dispatchers E, F only listen.
- FIG. 2 illustrates an example of a group call connection in the form of a voice group call service VGCS according to 3GPPTS42.068 (according to which specification speaking, listening, speaking and listening participants and dispatchers (who can speak without a speech authorization token) are provided), which are intended for a group (VGCS1 each defines a group address a (group identity of the group of the switching centers), a group call area I, and the identities of dispatchers x for this group.
- the group addresses a thus indicate all subscribers (service subscribers) which potential subscribers to a group call connection a group call area I can define a geographical area such as one or more radio cells or radio cell sectors.
- Dispatchers x are potential subscribers (ie according to the invention)
- SS also has a monitoring device), which can be added for example the GSM or external networks also ne regardless of their location intruruftagenen. If a group call VGCS is set up in accordance with 3GPPTS42.068, group call participants are asked if they want to participate and those who want to participate will be through traffic channels in
- Uplink and / or downlink direction connected to each other, with alternating speaker roles can be provided.
- FIG. 3 shows a group call connection in the form of a voice broadcast service VBS in accordance with, for example, 3GPPTS42.069.
- VBS voice broadcast service
- FIG. 4 shows a group call register GCR, in which data relating to group calls, such as the group call area, potential participants in the group call, dispatcher, etc., can be stored, the GCR being accessible from anchor MSCs and / or other switching devices or telecommunication network components.
- MC Monitoring Center
- FIG. 6 shows another example of a listening device according to the invention, in which a group device (“MSC w / GGSN / SGSN / etc.) Between the subscribers A - F (or AD) of the group call connection
- FIG. 7 shows a change of speaker during the monitoring of a group call, the reason for determining the identity of the speaker and checking whether the speaker is to be monitored (and thus whether the voice data and / or other data (for example image data)) of the group call connection are intercepted should be).
- a subscriber register determines the membership of a subscriber
- Subscriber registers can in particular be home registers of a mobile radio network (HLRs) with regard to subscribers entered there.
- HLRs mobile radio network
- VLR visitor registers visited by participants
- group identity information could be 'deselected' by a subscriber on the SIM, i.e. in the HLR and on the SIM, the subscriber is a member of this group, but does not listen to the calls (so it does not necessarily have to be monitored). It is therefore advisable to identify the "active" (listening and / or speaking) participants to the group IDs (e.g. at the start of a group connection and / or dynamically according to time intervals):
- a switching facility uses the status flag indication in the GCR to determine the current (ongoing)
- Group / broadcast calls with the given group ID's. This information is delivered via HI2 / IRI.
- the priority indicator can be used to decide in which group the monitored participant is participating. If two groups with the same priority are active, it cannot be decided in which group the monitored subscriber is listening. Both groups can register.
- a switching center sends an "Uplink Access Request" in an "Uplink Free Message on the Voice Group Call Channel Downlink.
- IMSI / MSISDN an indication representing their identity
- the subscriber sought can be identified, after which it can be decided whether the monitoring is to be ended again (a monitored person does not participate in the group call connection) or continued, as it could later happen that a monitored person takes part.
- Identification of a "subsequent talker” A subsequent talker (a subscriber who subsequently takes part in an already existing group call connection) should send his IMSI / MSISDN to a telecommunications network if he wants to receive an uplink (for the transmission of voice data sent by him).
- the message Uplink_Request is to be expanded with an identity information, after which it can be decided whether the monitoring is to be ended again (a monitored person does not participate in the group call connection) or continued because it
