  • the called-side MSC transmits routing information (a Temporary Local Directory Number (TLDN)) to the HLR in response to the request for routing information from the HLR. Thereafter, the HLR transmits the information about the location of the called terminal to the calling- side MSC based on the received routing information.
  • TLDN Temporary Local Directory Number

Abstract

La présente invention concerne un procédé et un dispositif permettant de fournir un contenu multimédia sous forme d'un signal de rappel au sein d'un à accès multiple par répartition en code à large bande (WCDMA). Ce procédé englobe les opérations suivantes : réception d'un premier signal de connexion d'appel émanant d'une passerelle MSC (mobile communication center) ; transmission d'un signal de demande de code de rappel multimédia (multimedia Ring Back Tone/MMRTB) à un serveur (MMRTB) ; réception d'un signal de réponse de code MMRTB comprenant des informations de code MMRTB fixé précédemment pour un terminal demandé depuis le serveur MMRTB ; transmission d'un second signal de réponse d'accès à un appel à la passerelle MSC en réponse au un premier signal de demande de connexion pour un premier appel ; ouverture d'un canal son-vidéo entre le MMRTB-IP et le terminal appelant en fonction du second signal de réponse d'accès et du troisième signal de réponse d'accès, et transmission d'un MMRTB correspondant aux informations de code MMRTB au terminal demandeur.
