Definitions

  • the invention relates to an emergency call system between a telecommunication device, and an emergency call center according to the preamble of claim 1.
  • IP Internet Protocol
  • a phone permanently assigned to an account or requires a login with an identification with a password.
  • a telephone which includes a login or logout function such that it requires a login or logout for the telephone function, can also assume the "status logout.” In this state, the telephone can not be used for making telephone calls It's practically like turning it off - a problem will now appear if an emergency call is needed during the logout state, which is then not possible.
  • the invention has for its object to provide a permanent emergency call system between a telecommunication device and an emergency call center, in which the telecommunication device comprises a commissioning state via a switchable logon function at a VoIP telecommunications service provider. It is assumed that the telecommunications terminal recommends to an IP infrastructure (eg router) is connected. The emergency call is only possible if the IP infrastructure is intact.
  • IP infrastructure eg router
  • an emergency call system between a telecommunication device, and an emergency call center in which the telecommunication device comprises a commissioning or log-on and log-off via a switchable logon function at a VoIP telecommunications service provider via an IP infrastructure consisting of at least one router.
  • access to VoIP services is added to the telecommunications device registered with the VoIP telecommunications service provider.
  • one or more country or world emergency center may be introduced that accept anonymous emergency calls from unregistered or deregistered users.
  • the functionality is to be understood as in today's MobiIfunknetzen (in contrast to a VoIP network), in which an emergency call is possible even without an inserted SIM card in the mobile phone.
  • an emergency call server with the public IP number of the emergency center, access will therefore take place without registering the user.
  • this IP address should be accessible via IP networks from the IP infrastructure service provider, or should become an own emergency call center of the VoIP provider.
  • the global (or region-wide) public IP emergency number may be entered into the telecommunications device or provided with the device. Call e.g. to usual emergency call telephone numbers "112" "HO”, "911" are always possible over the emergency call server, other telephone numbers not.
  • the telecommunication device in the logged-out state, the telecommunication device always uses the "address" of the emergency call server in order to convey calls to the emergency call telephone numbers, while in the logged-in state, the access is made via a normal server of the VoIP telecommunication service provider.
  • one or more emergency call numbers in the emergency call system can be very easily stored by means of one or more public IP numbers of one or more emergency centers in the telecommunication device. However, if the emergency center provides international emergency coverage, this upgrade is no longer required.
  • an emergency call system is sketched at VoIP-registered telecommunications device SUBS_TEL.
  • the telecommunication device SUBS_TEL is a telephone with access to a VoIP server VoIP_SERV of a VoIP telecommunication service provider (Voice Service Provider).
  • VoIP_SERV Voice Service Provider
  • An emergency call (Invite: 112) is initiated from the telephone via the IP infrastructure and, with an existing and recognized registration (Register / Sip Registrar) on the VoIP server of the VoIP telecommunications service provider, the emergency call via the VoIP server becomes an emergency center or an emergency telephone coverage N0T_TEL be transferred.
  • the emergency center has an emergency server N0T_SERV, which may include an IP address with which emergency calls are detected from the VoIP server.
  • Another connection such as a public communications network or a wireless network, between the VoIP server and the emergency center or the emergency service telephone enclosure could also be used.
  • the connection between an IP infrastructure with e.g. a router SWITCH and the VoIP server VoIP_SERV can thus come about.
  • the emergency call center has a public IP address for Internet access to the emergency server NOT_SERV, which is stored in the telephone for emergency calls (Invite: 112) and is now called up, therefore a new connection can be made between the telecommunication terminal the IP infrastructure and the emergency server NOT_SERV or the emergency service telephone enclosure NOT_TEL are created.
  • This new emergency call connection redirects the connection via the VoIP server VoIP_SERV according to FIG. 1.
  • a call of the telecommunication terminal SUBS_TEL at the emergency call center can take place without registration of the telecommunication terminal with the emergency call center.

Abstract

L'invention concerne un système d'appel d'urgence entre un appareil de télécommunication (SUBS_TEL), de préférence un appareil mobile, et une centrale d'appels d'urgence (NOT_SERV, NOT_TEL). Selon l'invention, l'appareil de télécommunication présente un état de fonctionnement qui est déterminé par une fonction de connexion pouvant être activée et désactivée (état de connexion et de déconnexion) auprès d'un fournisseur de service de télécommunication VoIP, par l'intermédiaire d'une infrastructure IP. La centrale d'appels d'urgence dispose d'un numéro IP public qui permet d'établir une liaison d'appel d'urgence entre l'appareil de télécommunication et la centrale d'appels d'urgence, sans passer par le fournisseur de service de télécommunication VoIP, lorsque la fonction de connexion de l'appareil de télécommunication est désactivée (état déconnecté), ce qui garantit que, même à l'état de déconnexion, l'appareil de télécommunication peut émettre un appel d'urgence non enregistré auprès du fournisseur de service de télécommunication VoIP.
