Definitions

  • the invention relates to a method for localizing a telephone terminal in a voice connection conducted over a packet network.
  • the invention is in the field of switching technology and affects in particular the provision of features for voice transmission over packet networks.
  • IP protocol Internet Protocol
  • Voice traffic is handled over packet networks. It is an endeavor to include as many features as possible, from telephony to circuit-switched networks (this is also referred to as TDM):
  • Time division multiplexing networks are known to also offer voice transmission over packet networks.
  • TDM networks A feature known from TDM networks is the localization of telephone subscribers based on their call numbers.
  • IP telephones i.e. Phones that send their voice data directly using the IP protocol and exchange signaling using the SIP protocol, for example, or PCs equipped with voice functionality
  • this function namely the localization of these end devices, is currently not available.
  • the object of the invention is to provide a method for localizing telephone terminals which also allows the localization of telephone terminals connected directly to packet networks.
  • a server in which telephone subscribers are registered with their call number and localization information assigned to the call number.
  • the location of the calling telephone set is triggered in the course of the voice connection (for example in the course of establishing the connection).
  • the localization information assigned to the number is queried from the server on the basis of the telephone number of the calling telephone device. The location of the calling telephone device is finally determined on the basis of this location information.
  • the method according to the invention is particularly advantageous with regard to telephony devices directly connected to the packet network, such as IP telephones or PCs provided with voice functionality.
  • the request to the server can be triggered in the switching system controlling the calling terminal. This request is then transmitted to the server where the location information is stored.
  • the telephone number of the calling telephone terminal can then be sent to the called terminal or a switching system responsible for this terminal, for example by email, SMS or fax.
  • the packet network address of the telephone terminal can also be stored in the server.
  • This additional information can e.g. serve to check the consistency of the information stored in the server.
  • the figure shows an IP telephone IP-Tnn, which is connected to an IP network IPNET.
  • a server SER is provided in this IP network IPNET for the registration of telephony devices.
  • the server SER is operated, for example, by an internet service provider or internet service provider.
  • the user of the IP telephone IP-Tnn is registered with the server SER. This can be an active registration by the user of the IP telephone IP-Tln or an automatic registration.
  • the figure shows a scenario for the case where the called subscriber is a PSTN (Public Switched Telephone Network) subscriber, ie is connected to the PSTN network via a local exchange Vst.
  • PSTN Public Switched Telephone Network
  • the exchanged data In the case of a voice connection between the IP telephone IP-Tln and the telephone of the B-subscriber B-Tln, the exchanged data must be adapted for the transmission over different networks. This adjustment is done in a gateway GW carried out, which adapts data coming from the IP network IPNET for the transmission via the PSTN network PSTN and also carries out an adaptation in the opposite direction.
  • the position of the IP telephone IP-Tln is localized.
  • the called subscriber B-subscriber is, for example, an emergency call center.
  • the local exchange VST of the B subscriber B-Tln determines that a connection to the emergency call center B-Tln is to be established, the information about the position of the A subscriber or IP telephone IP-Tln , which is to be determined for calls to the emergency call center, but is not available.
  • the local exchange VST then initiates the localization of the A subscriber or his terminal IP-Tln.
  • a message is sent to the server SER with which the desired information is queried based on the telephone number of the A subscriber IP subscriber.
  • Such a message is transmitted back to the gateway GW via the PSTN network and adapted there for transmission via the IPNET IP network.
  • the message for querying the desired localization information by means of the telephone number of the A subscriber IP-Tln is first transmitted to the IP-telephone IP-Tln and from there forwarded to the server SER.
  • multicast can be used, for example, to propagate the message to possible destinations through the network.
  • the message is then discarded by all recipients except the server SER.
  • a server SER is provided for the registration of telephone devices for each subnet.
  • a multicast can be carried out for the corresponding subnet.
  • servers SER which store the location information for terminals connected directly to the IP network
  • subscribers or terminals which generally require the location information, such as emergency services or emergency carriers, for example when setting up such a server SER be made known so that the B-subscriber B-subscriber already has the server address.
  • the server SER may send this localization information together with the telephone number of the A subscriber A-Tln (for better control) to the B-subscriber B-Tln or the associated local exchange VST. This can be done by first transmitting this information via the IPNET IP network, then adapting it to the gateway GW and finally transmitting it to the destination via the PSTN network PSTN. There the information is evaluated and the position of the calling subscriber IP-Tln is determined.

Abstract

La présente invention concerne un procédé pour localiser un terminal téléphonique (IP_Tln) dans le cadre d'une liaison téléphonique exécutée par l'intermédiaire d'un réseau à commutation de paquets (IPNET). A cet effet, un enregistrement du terminal téléphonique (IP-Tln), comprenant le numéro d'appel et des informations de localisation associées, est fait dans un serveur (SER) localisé dans le réseau à commutation de paquets (IPNET). Lorsque, à la suite d'une liaison téléphonique, la localisation du terminal téléphonique (IP-Tln) est déclenchée, la localisation du terminal téléphonique (IP-Tln) grâce au numéro d'appel du terminal téléphonique (IP-Tln), s'effectue par demande de la part du serveur (SER), des informations de localisation associées au numéro d'appel, et la position du terminal téléphonique (IP-Tln) est déterminée grâce aux informations de localisation. L'invention permet de mettre la caractéristique de puissance de la localisation de terminal, connue pour des réseaux TDM, également à la disposition de terminaux téléphoniques connectés directement à un réseau à commutation de paquets.
