Definitions

  • the invention relates to methods and devices for establishing a connection between a mobile radio subscriber initiating the connection setup and a further mobile radio subscriber or further mobile radio subscribers from a group of mobile radio subscribers.
  • the invention relates to services in which it is important to set up connections as quickly as possible, for example a so-called "push-to-talk” service (ie a "press a button to speak” service) for a mobile radio network in which a mobile radio subscriber connects to predefined (and moreover currently accessible) members of a group of mobile radio subscribers (and possibly also fixed network subscribers) by entering an entry such as, for example, pressing a button in his mobile station etc.
  • a so-called "push-to-talk” service ie a "press a button to speak” service
  • Such connections can be set up in different mobile radio networks such as GSM / CDMA / TDMA / WCDMA / TDCCMA / TDCSDMA / 4G mobile radio networks etc.
  • Members of a group can also be mobile radio subscribers who communicate with the other members of the group via different mobile radio networks and radio interfaces.
  • a channel used for the transmission of signaling data in the form of a PDP context for the transmission of signaling data and a voice channel in the form can be used between the mobile radio terminal of a member of the group and a mobile radio network another PDP context for the transmission of voice data between the mobile terminal and a mobile network.
  • the PDP context provided for signaling can be used to signal session control (including connection establishment and processing).
  • the voice channel in the form of a further PDP context can transmit voice data between in each case at least one mobile radio subscriber and a mobile radio network (for forwarding to the other mobile radio subscribers in a group).
  • the PDP context to be provided for the transmission of voice data can have a better quality (with regard to the delay and / or the loss rate).
  • US 2002/0181423 AI describes an apparatus and system for channel management and overhead functions associated with the use of certain channels for point-to-multipoint services in a cellular communication system. This enables point-to-multipoint and point-to-point communication services in an existing cellular communication system.
  • the object of the present invention is to enable a connection between a mobile radio subscriber and members of a group to be established quickly and easily and efficiently via at least one mobile radio network after input of a mobile radio subscriber of the group (in particular push-to-talk).
  • the object is achieved in each case by the subject matter of the independent claims.
  • voice data are initially transmitted between a mobile radio subscriber and a mobile radio network via a user data channel (first PDP context) which is also used for the transmission of signaling data until a further ter useful channel (second PDP context) is set up between this subscriber and the mobile radio network, whereupon voice data are transmitted via the second user channel
  • first PDP context user data channel
  • second PDP context further ter useful channel
  • the transmission of voice data can be easily and efficiently when a connection is established between the mobile radio subscriber and the mobile radio network for a push to-talk services are accelerated, since the participant can initially speak over the (already established) user data channel used for the transmission of signaling data, so that delays until the establishment of the voice channel (which can be more complex, especially when negotiating resources and / or Codecs are required) can be avoided.
  • such a method could be implemented by a change alone in the mobile radio terminal of a subscriber, the user data (for example voice data, streaming video data or data of interactive applications) initially via a first channel used for the transmission of signaling data (first Transmits PDP context) and, after establishing a second channel (second PDP context), transmits the user data via the second channel (and, if applicable, communicates this to the mobile radio network and / or receiving mobile radio terminals).
  • first Transmits PDP context first Transmits PDP context
  • second PDP context transmits the user data via the second channel (and, if applicable, communicates this to the mobile radio network and / or receiving mobile radio terminals).
  • a mobile radio terminal which according to the invention can initially transmit, for example, voice data over a first channel used for the transmission of signaling data, is on the phone with a member of a group whose mobile radio terminal cannot do this, the mobile radio network can connect to the further mobile radio terminal (which only uses voice data a voice channel can receive) send voice data to be transmitted via a (only) PDP context intended for voice transmission.
  • FIG. 1 shows the connection establishment according to the invention between a mobile radio terminal and a mobile radio network
  • FIG. 2 as a concrete example, schematically the parties involved in a push-to-talk connection.
  • UE-A mobile radio terminal
  • P-CSCF mobile radio network
  • Which mobile radio subscribers ie which mobile radio subscriber identities in a mobile radio subscriber identity card SIM etc. or which mobile radio terminals) are members of a group can be stored in a mobile radio terminal (and can also be communicated to at least one mobile radio network) and / or stored in a mobile radio network , After an entry such as a push of a button etc. on the part of a mobile subscriber's mobile terminal, a connection can be established to the members of this group.
  • a first PDP is first between the mobile radio terminal (UE-Al) and a switching center (GGSN2).
  • Context (5) is activated and SIP-based IMS registration (6) takes place here between the mobile radio terminal and a control device S-CSCF (4) of a mobile radio network.
  • a mobile terminal UE-A (1) of a mobile subscriber determines an entry regarding a desired connection setup to one or more members of a group (for example, pressing a specific key for a push-to-talk service), it sends 1 via a signaling channel (which does not have to correspond to the first PDP context) a message (7) to a POC server controlling the establishment of a connection between the participants in a group
  • the POC server 5 responds with a confirmation (8) (message "2,200 ok for invite") to the mobile radio terminal 1.
  • a mobile radio network (at least) is used between a mobile radio terminal UE-A 1 and a switching center (GGSN) (2) further PDP context (10) is provided, which is intended for the transmission of user data.
  • This user data can include voice, video or other data.
  • the construction of this second PDP context (10) takes longer than the immediate use of the already available first PDP context (and / or is even built up later than the first PDP context), so that the second PDP context for the User data is available later than the PDP context for the signaling data.
  • voice data are first transmitted via the first channel used for the transmission of signaling data from a mobile radio terminal (1) (in a known manner via an air interface and base stations, etc.) to a switching device (2) of a mobile radio network until the one for the transmission second PDP context provided by voice data has also been set up.
  • FIG. 2 schematically illustrates the data transmission in the case of a group call.
  • the user data is transferred between the mobile radio terminals (1) (with mobile radio subscriber identity cards SIM etc.) via an air interface (11) of a mobile radio network, base stations etc. (12), switching devices (GGSN 2), further switching devices (here GGSNs 13, 14), and others Base stations etc. (15, 26) and air interfaces (16, 17) to other mobile subscribers (mobile stations 18, 19) of a group (1, 18, 19).
  • the transmission between the switching devices (2, 13, 14) can take place directly, via GGSNs, SGSNs or group call switches (5).
  • voice data firstly via a faster established first PDP context (20) intended for signaling and then via a later or slower established but possibly better quality second PDP context.
  • user data user data of a user
  • first PDP context 23 or 25 first user data channel
  • second PDP context 22 or 24 second channel for user data
