Definitions

  • the invention relates to a method for transferring an existing logical data connection.
  • the logical data connection here is between a first subscriber terminal connected to a subscriber line of a telecommunications network and a switching center of the telecommunications network.
  • Such a telecommunications network is shown, for example, in FIG. 1.
  • the telecommunications network is connected to an access computer AP of a data network DN, e.g. the Internet, m connection.
  • a data network DN e.g. the Internet
  • Various subscriber terminals e.g. B. a personal computer PC, a corded telephone TF and a cordless handset SL with its base station BS are connected to a switching center VST.
  • This switching center has a connection via a circuit-switched public telephone network PSTN or via a packet-switching data network PN, e.g. X.25, to said access computer AP of the data network DN.
  • PN packet-switching data network
  • the public telephone network is also connected to a mobile communication network PLMN, which comprises a plurality of radio devices RBS for connecting a plurality of subscriber terminals via a radio interface.
  • a mobile communication network PLMN which comprises a plurality of radio devices RBS for connecting a plurality of subscriber terminals via a radio interface.
  • Such subscriber terminal devices are, for example, mobile stations MS, a laptop LT or a personal computer being connectable to one of the indicated mobile stations via a serial interface or a mobile station being integrable into a laptop or personal computer.
  • a subscriber of the telecommunications network has various subscriber terminals, for example as shown in FIG. 1, which all give him access to a data network, for example the Internet. Accordingly, the subscriber can receive, read and edit electronic mail (email) from the data network with his subscriber terminal device with a display, for example TF. It is assumed that the subscriber has set up a data connection to the data network with such a subscriber terminal in order to transmit his electronic mail from a so-called mail server of the data network, not shown in FIG. 1, to his subscriber terminal.

  • the object of the invention is to develop a method that solves the stated problems.
  • the basis of the invention is a method for transferring an existing logical data connection between a first subscriber terminal connected to a subscriber connection of a telecommunication network and a switching center of the telecommunication network from the first subscriber terminal to a second subscriber terminal which is connected to the subscriber connection of the first subscriber terminal. direction or is connected to another subscriber line of the telecommunications network.
  • the first subscriber terminal transmits a message regarding the communication state of the existing logical data connection to the second subscriber terminal and takes over the data connection in the communicated communication state, adapting its own state.
  • the communication status is understood to mean all agreements between the communication partners of the logical data connection that have already been “negotiated” when the connection is being established or during the data connection.
  • the communication state also relates to states which relate to activated applications and device settings of the first subscriber terminal.
  • the message relating to the communication status can in particular contain: the assigned data network address of the first subscriber terminal and / or information about the transmission bandwidth and / or information about a reserved quality quality and / or authorization information and / or setting information from applications and / or status information via the applications and / or synchronization information activated in the first subscriber terminal for one or more data transmission devices present in the subscriber terminal.

  • One embodiment of the invention relates to the aforementioned telecommunications network, which consists of at least one fixed network and / or at least one mobile network. Accordingly, a logical data connection that exists between a mobile station of the mobile network and the data network can be sent to a second subscriber terminal, e.g. a personal computer, which is connected to a subscriber line of the fixed network, and vice versa. A personal computer can also be connected directly to the mobile station and take over the existing data connection. Accordingly, the method according to the invention can be applied to different types of networks.
  • a further embodiment of the invention relates to the exchange of messages between the first subscriber terminal and the second subscriber terminal, both of which belong to a digital, preferably an ISDN subscriber line.
  • the message exchange takes place in that one of the subscriber terminals (T1, T2) sends a message addressed to the other of the subscriber connection to terminate the network, and this directs it both back towards the other of the subscriber terminals and further towards the switching center that either ignores or processes this message upon receipt.
  • the signaling protocol only has to be modified slightly so that the switching center can ignore or evaluate the message received.
  • a further development of the invention provides that the logical data connection is transferred from a first analog subscriber terminal to a second analog subscriber terminal which is connected to the analog subscriber terminal of the first subscriber terminal, the one from the first subscriber terminal taking over the logical data link beforehand established connection between subscriber line and the switching center of the telecommunications network mentioned above is maintained.
  • Subscriber terminal is initiated and after the takeover of the logical data connection the transmission of data is initiated by the second subscriber terminal. This minimizes the loss of data that would normally cause the lost data to be retransmitted, thereby reducing transmission bandwidth.

Abstract

Une communication de données logique existante entre un premier terminal d'abonné (T1) relié à un raccordement d'abonné d'un réseau de télécommunication et un central téléphonique (VST, AP) du réseau de télécommunication est transférée d'un premier terminal d'abonné (T1) à un deuxième terminal d'abonné (T2) qui est relié au raccordement d'abonné du premier terminal d'abonné ou à un autre raccordement d'abonné du deuxième réseau de télécommunication. Ce faisant, le deuxième terminal d'abonné reçoit un message transmis par le premier terminal d'abonné et concernant l'état (contexte) de la communication de données logiques existante et il reprend cette communication de données dans l'état signalé en adaptant à son propre état.
