(FR) IDENTIFICATION DES RAPPELS D'UN CENTRE DE RÉCEPTION D'APPELS D'URGENCE (PSAP) DANS DES SERVICES D'URGENCE D'UN SOUS-SYSTÈME MULTIMÉDIA IP
Abstract: front page image
(EN)A method and apparatus for identifying public safety answering point (PSAP) callbacks by transmitting, by a wireless transmit/receive unit (WTRU) in a first network, a registration message, to a PSAP in a second network. Upon registration, the WTRU receives a registration response including an information element (IE) and stores the IE. The PSAP, which may be located in either an internet protocol (IP) Network or a public switched telephone network (PSTN), transmits an emergency callback to the WTRU and includes the IE.
(FR)L'invention concerne un procédé et un appareil permettant d'identifier des rappels d'un centre de réception d'appels d'urgence (PSAP) en transmettant, par le biais d'une unité de transmission/réception sans fil (WTRU) dans un premier réseau, un message d'enregistrement à un PSAP dans un second réseau. Dès l'enregistrement, la WTRU reçoit une réponse d'enregistrement comprenant un élément d'information (IE) et enregistre l'IE. Le PSAP, qui peut se trouver dans un réseau IP ou un réseau téléphonique commuté public (PSTN), transmet un rappel d'urgence à la WTRU et comprend l'IE.
